  • 1 INDICATIONS AND USAGE

    1.1 Healing of Erosive or Ulcerative GERD in Adults

    ACIPHEX delayed-release tablets are indicated for short-term (4 to 8 weeks) treatment in the healing and symptomatic relief of erosive or ulcerative gastroesophageal reflux disease (GERD).  For those patients who have not healed after 8 weeks of treatment, an additional 8-week course of ACIPHEX may be considered.

    1.2 Maintenance of Healing of Erosive or Ulcerative GERD in Adults

    ACIPHEX delayed-release tablets are indicated for maintaining healing and reduction in relapse rates of heartburn symptoms in patients with erosive or ulcerative gastroesophageal reflux disease (GERD Maintenance).  Controlled studies do not extend beyond 12 months.

    1.3 Treatment of Symptomatic GERD in Adults 

    ACIPHEX delayed-release tablets are indicated for the treatment of daytime and nighttime heartburn and other symptoms associated with GERD in adults for up to 4 weeks. 

    1.4 Healing of Duodenal Ulcers in Adults

    ACIPHEX delayed-release tablets are indicated for short-term (up to four weeks) treatment in the healing and symptomatic relief of duodenal ulcers.  Most patients heal within four weeks.

    1.5 Helicobacter pylori Eradication to Reduce the Risk of Duodenal Ulcer Recurrence in Adults

    ACIPHEX delayed-release tablets, in combination with amoxicillin and clarithromycin as a three drug regimen, are indicated for the treatment of patients with H. pylori infection and duodenal ulcer disease (active or history within the past 5 years) to eradicate H. pylori.  Eradication of H. pylori has been shown to reduce the risk of duodenal ulcer recurrence. 

    In patients who fail therapy, susceptibility testing should be done.  If resistance to clarithromycin is demonstrated or susceptibility testing is not possible, alternative antimicrobial therapy should be instituted [see Clinical Pharmacology (12.2) and the full prescribing information for clarithromycin].

    1.6 Treatment of Pathological Hypersecretory Conditions, Including Zollinger-Ellison Syndrome in Adults

    ACIPHEX delayed-release tablets are indicated for the long-term treatment of pathological hypersecretory conditions, including Zollinger-Ellison syndrome.

    1.7 Treatment of Symptomatic GERD in Adolescent Patients 12 Years of Age and Older

    ACIPHEX delayed-release tablets are indicated for the treatment of symptomatic GERD in adolescents 12 years of age and above for up to 8 weeks.

  • 2 DOSAGE AND ADMINISTRATION

    Table 1 shows the recommended dosage of ACIPHEX delayed-release tablets in adults and adolescent patients 12 years of age and older. The use of ACIPHEX delayed-release tablets is not recommended for use in pediatric patients 1 year to less than 12 years of age because the lowest available tablet strength (20 mg) exceeds the recommended dose for these patients. Use another rabeprazole formulation for pediatric patients 1 year to less than 12 years of age.

  • 4 CONTRAINDICATIONS

    ACIPHEX is contraindicated in patients with known hypersensitivity to rabeprazole, substituted benzimidazoles, or to any component of the formulation.  Hypersensitivity reactions may include anaphylaxis, anaphylactic shock, angioedema, bronchospasm, acute interstitial nephritis, and urticaria [see Adverse Reactions (6)].

     PPIs, including ACIPHEX, are contraindicated with rilpivirine-containing products [see Drug Interactions (7)].

    For information about contraindications of antibacterial agents (clarithromycin and amoxicillin) indicated in combination with ACIPHEX delayed-release tablets, refer to the Contraindications section of their package inserts.

  • 5 WARNINGS AND PRECAUTIONS

    5.1 Presence of Gastric Malignancy

    Symptomatic response to therapy with ACIPHEX does not preclude the presence of gastric malignancy.

    Patients with healed GERD were treated for up to 40 months with ACIPHEX delayed-release tablets and monitored with serial gastric biopsies.  Patients without H. pylori infection (221 of 326 patients) had no clinically important pathologic changes in the gastric mucosa.  Patients with H. pylori infection at baseline (105 of 326 patients) had mild or moderate inflammation in the gastric body or mild inflammation in the gastric antrum.  Patients with mild grades of infection or inflammation in the gastric body tended to change to moderate, whereas those graded moderate at baseline tended to remain stable.  Patients with mild grades of infection or inflammation in the gastric antrum tended to remain stable.  At baseline 8% of patients had atrophy of glands in the gastric body and 15% had atrophy in the gastric antrum.  At endpoint, 15% of patients had atrophy of glands in the gastric body and 11% had atrophy in the gastric antrum.  Approximately 4% of patients had intestinal metaplasia at some point during follow-up, but no consistent changes were seen.

    5.2 Interaction with Warfarin

    Steady state interactions of rabeprazole and warfarin have not been adequately evaluated in patients.  There have been reports of increased INR and prothrombin time in patients receiving a proton pump inhibitor and warfarin concomitantly.  Increases in INR and prothrombin time may lead to abnormal bleeding and even death.  Patients treated with ACIPHEX delayed-release tablets and warfarin concomitantly may need to be monitored for increases in INR and prothrombin time [see Drug Interactions (7)].

    5.3 Acute Interstitial Nephritis

    Acute interstitial nephritis has been observed in patients taking PPIs including ACIPHEX.  Acute interstitial nephritis may occur at any point during PPI therapy and is generally attributed to an idiopathic hypersensitivity reaction.  Discontinue ACIPHEX if acute interstitial nephritis develops [see Contraindications (4)].

    5.4 Cyanocobalamin (vitamin B-12) Deficiency

    Daily treatment with any acid-suppressing medications over a long period of time (e.g., longer than 3 years) may lead to malabsorption of cyanocobalamin (vitamin B-12) caused by hypo- or achlorhydria.  Rare reports of cyanocobalamin deficiency occurring with acid-suppressing therapy have been reported in the literature.  This diagnosis should be considered if clinical symptoms consistent with cyanocobalamin deficiency are observed in patients treated with ACIPHEX.

    5.5 Clostridium difficile Associated Diarrhea

    Published observational studies suggest that PPI therapy like ACIPHEX may be associated with an increased risk of Clostridium difficile associated diarrhea, especially in hospitalized patients.  This diagnosis should be considered for diarrhea that does not improve [see Adverse Reactions (6.2)].

    Patients should use the lowest dose and shortest duration of PPI therapy appropriate to the condition being treated.

    Clostridium difficile associated diarrhea (CDAD) has been reported with use of nearly all antibacterial agents.  For more information specific to antibacterial agents (clarithromycin and amoxicillin) indicated for use in combination with ACIPHEX, refer to Warnings and Precautions sections of the corresponding prescribing information.

    5.6 Bone Fracture

    Several published observational studies in adults suggest that PPI therapy may be associated with an increased risk for osteoporosis-related fractures of the hip, wrist, or spine.  The risk of fracture was increased in patients who received high-dose, defined as multiple daily doses, and long-term PPI therapy (a year or longer).  Patients should use the lowest dose and shortest duration of PPI therapy appropriate to the condition being treated.  Patients at risk for osteoporosis-related fractures should be managed according to established treatment guidelines [see Dosage and Administration (2), Adverse Reactions (6.2)].

    5.7 Hypomagnesemia

    Hypomagnesemia, symptomatic and asymptomatic, has been reported rarely in patients treated with PPIs for at least three months, in most cases after a year of therapy.  Serious adverse events include tetany, arrhythmias, and seizures.  In most patients, treatment of hypomagnesemia required magnesium replacement and discontinuation of the PPI. 

    For patients expected to be on prolonged treatment or who take PPIs with medications such as digoxin or drugs that may cause hypomagnesemia (e.g., diuretics), healthcare professionals may consider monitoring magnesium levels prior to initiation of PPI treatment and periodically [see Adverse Reactions (6.2)].

    5.8 Interaction with Methotrexate

    Literature suggests that concomitant use of PPIs with methotrexate (primarily at high dose; see methotrexate prescribing information) may elevate and prolong serum concentrations of methotrexate and/or its metabolite, possibly leading to methotrexate toxicities.  In high-dose methotrexate administration, a temporary withdrawal of the PPI may be considered in some patients [see Drug Interactions (7)].

  • 6 ADVERSE REACTIONS

    The following serious adverse reactions are described below and elsewhere in labeling:

    6.1 Clinical Studies Experience

    Because clinical trials are conducted under varying conditions, adverse reaction rates observed in the clinical trials of a drug cannot be directly compared to rates in the clinical trials of another drug and may not reflect the rates observed in practice.

    Adults

    The data described below reflect exposure to ACIPHEX delayed-release tablets in 1064 adult patients exposed for up to 8 weeks.  The studies were primarily placebo- and active-controlled trials in adult patients with Erosive or Ulcerative Gastroesophageal Reflux Disease (GERD), Duodenal Ulcers and Gastric Ulcers.  The population had a mean age of 53 years (range 18-89 years) and had a ratio of approximately 60% male: 40% female.  The racial distribution was 86% Caucasian, 8% African American, 2% Asian, and 5% other.  Most patients received either 10 mg, 20 mg or 40 mg per day of ACIPHEX delayed-release tablets. 

    An analysis of adverse reactions appearing in ≥2% of patients treated with ACIPHEX delayed-release tablets (n=1064) and with a greater frequency than placebo (n=89) in controlled North American and European acute treatment trials, revealed the following adverse reactions:  pain (3% vs. 1%), pharyngitis (3% vs. 2%), flatulence (3% vs. 1%), infection (2% vs. 1%), and constipation (2% vs. 1%). 

    Three long-term maintenance studies consisted of a total of 740 adult patients; at least 54% of adult patients were exposed to ACIPHEX delayed-release tablets for 6 months and at least 33% were exposed for 12 months.  Of the 740 adult patients, 247 (33%) and 241 (33%) patients received 10 mg and 20 mg of ACIPHEX delayed-release tablets, respectively, while 169 (23%) patients received placebo and 83 (11%) received omeprazole.

    The safety profile of rabeprazole in the maintenance studies in adults was consistent with what was observed in the acute studies.

    Less common adverse reactions seen in controlled clinical trials (<2% of patients treated with ACIPHEX delayed-release tablets and greater than placebo) and for which there is a possibility of a causal relationship to rabeprazole, include the following:  headache, abdominal pain, diarrhea, dry mouth, dizziness, peripheral edema, hepatic enzyme increase, hepatitis, hepatic encephalopathy, myalgia, and arthralgia.

    Combination Treatment with Amoxicillin and Clarithromycin:  In clinical trials using combination therapy with rabeprazole plus amoxicillin and clarithromycin (RAC), no adverse reactions unique to this drug combination were observed.  In the U.S. multicenter study, the most frequently reported drug related adverse reactions for patients who received RAC therapy for 7 or 10 days were diarrhea (8% and 7%) and taste perversion (6% and 10%), respectively.

    No clinically significant laboratory abnormalities particular to the drug combinations were observed.

    For more information on adverse reactions or laboratory changes with amoxicillin or clarithromycin, refer to their respective prescribing information, Adverse Reactions section.

    Pediatrics

    In a multicenter, open-label study of adolescent patients 12 to 16 years of age with a clinical diagnosis of symptomatic GERD or endoscopically proven GERD, the adverse event profile was similar to that of adults.  The adverse reactions reported without regard to relationship to ACIPHEX delayed-release tablets that occurred in ≥2% of 111 patients were headache (9.9%), diarrhea (4.5%), nausea (4.5%), vomiting (3.6%), and abdominal pain (3.6%).  The related reported adverse reactions that occurred in ≥2% of patients were headache (5.4%) and nausea (1.8%).  There were no adverse reactions reported in this study that were not previously observed in adults.

    6.2 Postmarketing Experience

    The following adverse reactions have been identified during post approval use of rabeprazole.  Because these reactions are reported voluntarily from a population of uncertain size, it is not always possible to reliably estimate their frequency or establish a causal relationship to drug exposure:  sudden death; coma, hyperammonemia; jaundice; rhabdomyolysis; disorientation and delirium; anaphylaxis; angioedema; bullous and other drug eruptions of the skin; severe dermatologic reactions, including toxic epidermal necrolysis (some fatal), Stevens-Johnson syndrome, and erythema multiforme; interstitial pneumonia; interstitial nephritis; TSH elevations; bone fractures; hypomagnesemia and Clostridium difficile-associated diarrhea.  In addition, agranulocytosis, hemolytic anemia, leukopenia, pancytopenia, and thrombocytopenia have been reported.  Increases in prothrombin time/INR in patients treated with concomitant warfarin have been reported.

  • 7 DRUG INTERACTIONS

    Table 2 includes drugs with clinically important drug interactions when administered concomitantly with ACIPHEX delayed-release tablets and instructions for preventing or managing them.

    Consult the labeling of concomitantly used drugs to obtain further information about interactions with PPIs.

    Table 2: Clinically Relevant Interactions Affecting Drugs Co-Administered with ACIPHEX Delayed-Release Tablets 
    Antiretrovirals
    Clinical Impact:The effect of PPI on antiretroviral drugs is variable.  The clinical importance and the mechanisms behind these interactions are not always known.
    • Decreased exposure of some antiretroviral drugs (e.g., rilpivirine, atazanavir, and nelfinavir) when used concomitantly with rabeprazole may reduce antiviral effect and promote the development of drug resistance.
    • Increased exposure of other antiretroviral drugs (e.g., saquinavir) when used concomitantly with rabeprazole may increase toxicity.
    • There are other antiretroviral drugs which do not result in clinically relevant interactions with rabeprazole.
    Intervention:Rilpivirine-containing products:  Concomitant use with ACIPHEX delayed-release tablets is contraindicated [see Contraindications (4)].  See prescribing information.
         
    Atazanavir:  See prescribing information for atazanavir for dosing information.
        
    Nelfinavir: Avoid concomitant use with ACIPHEX delayed-release tablets. See prescribing information for nelfinavir.
        
    Saquinavir:  See the prescribing information for saquinavir and monitor for potential saquinavir toxicities.
         
    Other antiretrovirals:  See prescribing information.
    Warfarin
    Clinical Impact:Increased INR and prothrombin time in patients receiving PPIs, including rabeprazole, and warfarin concomitantly.  Increases in INR and prothrombin time may lead to abnormal bleeding and even death [see Warnings and Precautions (5.2)].
    Intervention:Monitor INR and prothrombin time. Dose adjustment of warfarin may be needed to maintain target INR range.  See prescribing information for warfarin.
    Methotrexate
    Clinical Impact:Concomitant use of rabeprazole with methotrexate (primarily at high dose) may elevate and prolong serum levels of methotrexate and/or its metabolite hydroxymethotrexate, possibly leading to methotrexate toxicities.  No formal drug interaction studies of methotrexate with PPIs have been conducted [see Warnings and Precautions (5.8)].
    Intervention:A temporary withdrawal of ACIPHEX delayed-release tablets may be considered in some patients receiving high dose methotrexate administration.
    Digoxin
    Clinical Impact:Potential for increased exposure of digoxin [see Clinical Pharmacology (12.3)].
    Intervention:Monitor digoxin concentrations. Dose adjustment of digoxin may be needed to maintain therapeutic drug concentrations. See prescribing information for digoxin.
    Drugs Dependent on Gastric pH for Absorption (e.g., iron salts, erlotinib, dasatinib, nilotinib, mycophenolate mofetil, ketoconazole, itraconazole)
    Clinical Impact:Rabeprazole can reduce the absorption of drugs due to its effect on reducing intragastric acidity. 
    Intervention:Mycophenolate mofetil (MMF): Co-administration of PPIs in healthy subjects and in transplant patients receiving MMF has been reported to reduce the exposure to the active metabolite, mycophenolic acid (MPA), possibly due to a decrease in MMF solubility at an increased gastric pH.  The clinical relevance of reduced MPA exposure on organ rejection has not been established in transplant patients receiving PPIs and MMF.  Use ACIPHEX delayed-release tablets with caution in transplant patients receiving MMF.
    See the prescribing information for other drugs dependent on gastric pH for absorption.
    Combination Therapy with Clarithromycin and Amoxicillin
    Clinical Impact:Concomitant administration of clarithromycin with other drugs can lead to serious adverse reactions, including potentially fatal arrhythmias, and are contraindicated .
         
    Amoxicillin also has drug interactions.
    Intervention:See Contraindications and Warnings and Precautions in prescribing information for clarithromycin.
          
    See Drug Interactions in prescribing information for amoxicillin.
        
  • 8 USE IN SPECIFIC POPULATIONS

    8.1 Pregnancy 

    Risk Summary

    There are no available human data on ACIPHEX use in pregnant women to inform the drug associated risk. The background risk of major birth defects and miscarriage for the indicated populations are unknown. However, the background risk in the U.S. general population of major birth defects is 2 to 4% and of miscarriage is 15 to 20% of clinically recognized pregnancies.  No evidence of adverse developmental effects were seen in animal reproduction studies with rabeprazole administered during organogenesis at 13 and 8 times the human area under the plasma concentration-time curve (AUC) at the recommended dose for GERD,in rats and rabbits, respectively [see Data].

    Changes in bone morphology were observed in offspring of rats treated with oral doses of a different PPI through most of pregnancy and lactation [see Data].  Advise pregnant women of the potential risk to a fetus.

    Data

    Animal Data

    Embryo-fetal developmental studies have been performed in rats during organogenesis at intravenous doses of rabeprazole up to 50 mg/kg/day (plasma AUC of 11.8 µghr/mL, about 13 times the human exposure at the recommended oral dose for GERD) and rabbits at intravenous doses up to 30 mg/kg/day (plasma AUC of 7.3 µghr/mL, about 8 times the human exposure at the recommended oral dose for GERD) and have revealed no evidence of harm to the fetus due to rabeprazole.

    Administration of rabeprazole to rats in late gestation and during lactation at an oral dose of 400 mg/kg/day (about 195-times the human oral dose based on mg/m2) resulted in decreases in body weight gain of the pups.

    A pre- and postnatal developmental toxicity study in rats with additional endpoints to evaluate bone development was performed with a different PPI at about 3.4 to 57 times an oral human dose on a body surface area basis. Decreased femur length, width and thickness of cortical bone, decreased thickness of the tibial growth plate, and minimal to mild bone marrow hypocellularity were noted at doses of this PPI equal to or greater than 3.4 times an oral human dose on a body surface area basis.  Physeal dysplasia in the femur was also observed in offspring after in utero and lactational exposure to the PPI at doses equal to or greater than 33.6 times an oral human dose on a body surface area basis.  Effects on maternal bone were observed in pregnant and lactating rats in a pre- and postnatal toxicity study when the PPI was administered at oral doses of 3.4 to 57 times an oral human dose on a body surface area basis.  When rats were dosed from gestational day 7 through weaning on postnatal day 21, a statistically significant decrease in maternal femur weight of up to 14% (as compared to placebo treatment) was observed at doses equal to or greater than 33.6 times an oral human dose on a body surface area basis.

    8.2 Lactation

    Risk Summary

    Lactation studies have not been conducted to assess the presence of rabeprazole in human milk, the effects of rabeprazole on the breastfed infant, or the effects of rabeprazole on milk production.  Rabeprazole is present in rat milk. The development and health benefits of breastfeeding should be considered along with the mother’s clinical need for ACIPHEX and any potential adverse effects on the breastfed infant from ACIPHEX or from the underlying maternal condition.

    8.4 Pediatric Use

    The safety and effectiveness of ACIPHEX delayed-release tablets have been established in pediatric patients for adolescent patients 12 years of age and older for the treatment of symptomatic GERD. Use of ACIPEX delayed-release tablets in this age group is supported by  adequate and well controlled studies in adults and a multicenter, randomized, open-label, parallel-group study in 111 adolescent patients 12 to 16 years of age. Patients had a clinical diagnosis of symptomatic GERD, or suspected or endoscopically proven GERD and were randomized to either 10 mg or 20 mg once daily for up to 8 weeks for the evaluation of safety and efficacy.  The adverse reaction profile in adolescent patients was similar to that of adults.  The related reported adverse reactions that occurred in ≥2% of patients were headache (5%) and nausea (2%).  There were no adverse reactions reported in these studies that were not previously observed in adults. 

    The safety and effectiveness of ACIPHEX delayed-release tablets have not been established in pediatric patients for:

    • Healing of Erosive or Ulcerative GERD
    • Maintenance of Healing of Erosive or Ulcerative GERD
    • Treatment of Symptomatic GERD
    • Healing of Duodenal Ulcers
    • Helicobacter pylori Eradication to Reduce the Risk of Duodenal Ulcer Recurrence
    • Treatment of Pathological Hypersecretory Conditions, Including Zollinger-Ellison Syndrome

    ACIPHEX delayed-release 20 mg tablets are not recommended for use in pediatric patients less than 12 years of age because the tablet strength exceeds the recommended dose for these patients [see Dosage and Administration (2)].  For pediatric patients 1 year to less than 12 years of age consider another rabeprazole formulation.  The safety and effectiveness of a different dosage form and dosage strength of rabeprazole has been established in pediatric patients 1 to 11 years for the treatment of GERD.

    Juvenile Animal Data

    Studies in juvenile and young adult rats and dogs were performed.  In juvenile animal studies rabeprazole sodium was administered orally to rats for up to 5 weeks and to dogs for up to 13 weeks, each commencing on Day 7 post-partum and followed by a 13-week recovery period.  Rats were dosed at 5, 25, or 150 mg/kg/day and dogs were dosed at 3, 10, or 30 mg/kg/day.  The data from these studies were comparable to those reported for young adult animals.  Pharmacologically mediated changes, including increased serum gastrin levels and stomach changes, were observed at all dose levels in both rats and dogs.  These observations were reversible over the 13-week recovery periods.  Although body weights and/or crown-rump lengths were minimally decreased during dosing, no effects on the development parameters were noted in either juvenile rats or dogs.

    When juvenile animals were treated for 28 days with a different PPI at doses equal to or greater than 34 times the daily oral human dose on a body surface area basis, overall growth was affected and treatment-related decreases in body weight (approximately 14%) and body weight gain, and decreases in femur weight and femur length were observed.  

    8.5 Geriatric Use

    Of the total number of subjects (n=2009) in clinical studies of ACIPHEX delayed-release tablets, 19% were 65 years and over, while 4% were 75 years and over.  No overall differences in safety or effectiveness were observed between these subjects and younger subjects, and other reported clinical experience has not identified differences in responses between the elderly and younger patients, but greater sensitivity of some older individuals cannot be ruled out.

    8.6 Hepatic Impairment

    Administration of ACIPHEX delayed-release tablets to patients with mild to moderate hepatic impairment (Child-Pugh Class A and B, respectively) resulted in increased exposure and decreased elimination [see Clinical Pharmacology (12.3)].  No dosage adjustment is necessary in patients with mild to moderate hepatic impairment. There is no information in patients with severe hepatic impairment (Child-Pugh Class C).  Avoid use of ACIPHEX delayed-release tablets in patients with severe hepatic impairment; however, if treatment is necessary, monitor patients for adverse reactions [see Warnings and Precautions (5), Adverse Reactions (6)].

  • 10 OVERDOSAGE

    Seven reports of accidental overdosage with rabeprazole have been received.  The maximum reported overdose was 80 mg.  There were no clinical signs or symptoms associated with any reported overdose.  Patients with Zollinger-Ellison syndrome have been treated with up to 120  mg rabeprazole once daily.  No specific antidote for rabeprazole is known.  Rabeprazole is extensively protein bound and is not readily dialyzable.

    In the event of overdosage, treatment should be symptomatic and supportive.  

    If over-exposure occurs, call your Poison Control Center at 1-800-222-1222 for current information on the management of poisoning or overdosage.

  • 11 DESCRIPTION

    The active ingredient in ACIPHEX delayed-release tablets is rabeprazole sodium, which is a proton pump inhibitor.  It is a substituted benzimidazole known chemically as 2-[[[4-(3-methoxypropoxy)-3-methyl-2-pyridinyl]-methyl]sulfinyl]-1H–benzimidazole sodium salt.  It has an empirical formula of C18H20N3NaO3S and a molecular weight of 381.42.  Rabeprazole sodium is a white to slightly yellowish-white solid.  It is very soluble in water and methanol, freely soluble in ethanol, chloroform, and ethyl acetate and insoluble in ether and n-hexane.  The stability of rabeprazole sodium is a function of pH; it is rapidly degraded in acid media, and is more stable under alkaline conditions.  The structural figure is:

  • 12 CLINICAL PHARMACOLOGY

    12.1 Mechanism of Action

    Rabeprazole belongs to a class of antisecretory compounds (substituted benzimidazole proton-pump inhibitors) that do not exhibit anticholinergic or histamine H2-receptor antagonist properties, but suppress gastric acid secretion by inhibiting the gastric H+, K+ATPase at the secretory surface of the gastric parietal cell.  Because this enzyme is regarded as the acid (proton) pump within the parietal cell, rabeprazole has been characterized as a gastric proton-pump inhibitor. Rabeprazole blocks the final step of gastric acid secretion.

    In gastric parietal cells, rabeprazole is protonated, accumulates, and is transformed to an active sulfenamide.  When studied in vitro, rabeprazole is chemically activated at pH 1.2 with a half-life of 78 seconds.  It inhibits acid transport in porcine gastric vesicles with a half-life of 90 seconds.

    12.2 Pharmacodynamics

    Antisecretory Activity

    The antisecretory effect begins within one hour after oral administration of 20 mg ACIPHEX delayed-release tablets.  The median inhibitory effect of rabeprazole on 24 hour gastric acidity is 88% of maximal after the first dose.  A 20 mg dose of ACIPHEX delayed-release tablets inhibits basal and peptone meal-stimulated acid secretion versus placebo by 86% and 95%, respectively, and increases the percent of a 24-hour period that the gastric pH>3 from 10% to 65% (see table below).  This relatively prolonged pharmacodynamic action compared to the short pharmacokinetic half-life (1 to 2 hours) reflects the sustained inactivation of the H+, K+ATPase.

    Compared to placebo, 10 mg, 20 mg, and 40 mg of ACIPHEX delayed-release tablets, administered once daily for 7 days significantly decreased intragastric acidity with all doses for each of four meal-related intervals and the 24-hour time period overall.  In this study, there were no statistically significant differences between doses; however, there was a significant dose-related decrease in intragastric acidity.  The ability of rabeprazole to cause a dose-related decrease in mean intragastric acidity is illustrated below.

    Effects on Esophageal Acid Exposure

    In patients with GERD and moderate to severe esophageal acid exposure, a dose of 20 mg and 40 mg per day of ACIPHEX delayed-release tablets decreased 24-hour esophageal acid exposure.  After seven days of treatment, the percentage of time that the esophageal pH was less than 4 decreased from baselines of 24.7% for 20 mg and 23.7% for 40 mg, to 5.1% and 2.0%, respectively.  Normalization of 24-hour intraesophageal acid exposure was correlated to gastric pH greater than 4 for at least 35% of the 24-hour period; this level was achieved in 90% of subjects receiving ACIPHEX 20 mg and in 100% of subjects receiving ACIPHEX 40 mg.  With ACIPHEX 20 mg and 40 mg per day, significant effects on gastric and esophageal pH were noted after one day of treatment, and more pronounced after seven days of treatment.

    Effects on Serum Gastrin

    The median fasting gastrin level increased in a dose-related manner in patients treated once daily with ACIPHEX delayed-release tablets for up to eight weeks for ulcerative or erosive esophagitis and in patients treated for up to 52 weeks to prevent recurrence of disease.  The group median values stayed within the normal range.

    In a group of subjects treated with 20 mg ACIPHEX delayed-release tablets for 4 weeks a doubling of mean serum gastrin concentrations was observed.  Approximately 35% of these treated subjects developed serum gastrin concentrations above the upper limit of normal.

    Effects on Enterochromaffin-like (ECL) Cells

    Increased serum gastrin secondary to antisecretory agents stimulates proliferation of gastric ECL cells which, over time, may result in ECL cell hyperplasia in rats and mice and gastric carcinoids in rats, especially in females [see Nonclinical Toxicology (13.1)].

    In over 400 patients treated with ACIPHEX delayed-release tablets (10 or 20 mg) once daily for up to one year, the incidence of ECL cell hyperplasia increased with time and dose, which is consistent with the pharmacological action of the proton-pump inhibitor.  No patient developed the adenomatoid, dysplastic or neoplastic changes of ECL cells in the gastric mucosa.  No patient developed the carcinoid tumors observed in rats.

    Endocrine Effects

    Studies in humans for up to one year have not revealed clinically significant effects on the endocrine system.  In healthy male subjects treated with ACIPHEX delayed-release tablets for 13 days, no clinically relevant changes have been detected in the following endocrine parameters examined:  17 β-estradiol, thyroid stimulating hormone, tri-iodothyronine, thyroxine, thyroxine-binding protein, parathyroid hormone, insulin, glucagon, renin, aldosterone, follicle-stimulating hormone, luteotrophic hormone, prolactin, somatotrophic hormone, dehydroepiandrosterone, cortisol-binding globulin, and urinary 6β-hydroxycortisol, serum testosterone and circadian cortisol profile.

    Other Effects

    In humans treated with ACIPHEX delayed-release tablets for up to one year, no systemic effects have been observed on the central nervous, lymphoid, hematopoietic, renal, hepatic, cardiovascular, or respiratory systems.  No data are available on long-term treatment with ACIPHEX delayed-release tablets and ocular effects.

    12.3 Pharmacokinetics

    After oral administration of 20 mg ACIPHEX delayed-release tablets, peak plasma concentrations (Cmax) of rabeprazole occur over a range of 2 to 5 hours (Tmax).  The rabeprazole Cmax and AUC are linear over an oral dose range of 10 mg to 40 mg.  There is no appreciable accumulation when doses of 10 mg to 40 mg are administered every 24 hours; the pharmacokinetics of rabeprazole is not altered by multiple dosing.

    Absorption

    Absolute bioavailability for a 20 mg oral tablet of rabeprazole (compared to intravenous administration) is approximately 52%.  When ACIPHEX delayed-release tablets are administered with a high fat meal, Tmax is variable; which concomitant food intake may delay the absorption up to 4 hours or longer.  However, the Cmax and the extent of rabeprazole absorption (AUC) are not significantly altered.  Thus ACIPHEX delayed-release tablets may be taken without regard to timing of meals.

    Distribution

    Rabeprazole is 96.3% bound to human plasma proteins.

    Elimination

    Metabolism:  Rabeprazole is extensively metabolized.  A significant portion of rabeprazole is metabolized via systemic nonenzymatic reduction to a thioether compound.  Rabeprazole is also metabolized to sulphone and desmethyl compounds via cytochrome P450 in the liver.  The thioether and sulphone are the primary metabolites measured in human plasma.  These metabolites were not observed to have significant antisecretory activity.  In vitro studies have demonstrated that rabeprazole is metabolized in the liver primarily by cytochromes P450 3A (CYP3A) to a sulphone metabolite and cytochrome P450 2C19 (CYP2C19) to desmethyl rabeprazole. CYP2C19 exhibits a known genetic polymorphism due to its deficiency in some sub-populations (e.g., 3 to 5% of Caucasians and 17 to 20% of Asians).  Rabeprazole metabolism is slow in these sub-populations, therefore, they are referred to as poor metabolizers of the drug.

    Excretion:  Following a single 20 mg oral dose of 14C-labeled rabeprazole, approximately 90% of the drug was eliminated in the urine, primarily as thioether carboxylic acid; its glucuronide, and mercapturic acid metabolites.  The remainder of the dose was recovered in the feces.  Total recovery of radioactivity was 99.8%.  No unchanged rabeprazole was recovered in the urine or feces.

    Specific Populations

    Age: Geriatric Population:  In 20 healthy elderly subjects administered 20 mg ACIPHEX delayed-release tablets once daily for seven days, AUC values approximately doubled and the Cmax increased by 60% compared to values in a parallel younger control group. There was no evidence of drug accumulation after once daily administration [see Use in Specific Population (8.5)].

    Age: Pediatric Population:  The pharmacokinetics of rabeprazole was studied in 12 adolescent patients with GERD 12 to 16 years of age, in a multicenter study.  Patients received 20 mg ACIPHEX delayed-release tablets once daily for five or seven days.  An approximate 40% increase in rabeprazole exposure was noted following 5 to 7 days of dosing compared with the exposure after 1 day dosing.  Pharmacokinetic parameters in adolescent patients with GERD 12 to 16 years of age were within the range observed in healthy adult subjects.

    Sex and Race/Ethnicity:  In analyses adjusted for body mass and height, rabeprazole pharmacokinetics showed no clinically significant differences between male and female subjects.  In studies that used different formulations of rabeprazole, AUC0-∞ values for healthy Japanese men were approximately 50 to 60% greater than values derived from pooled data from healthy men in the United States.

    Renal Impairment:  In 10 patients with stable end-stage renal disease requiring maintenance hemodialysis (creatinine clearance ≤5 mL/min/1.73 m2), no clinically significant differences were observed in the pharmacokinetics of rabeprazole after a single 20 mg dose of ACIPHEX delayed-release tablets when compared to 10 healthy subjects.

    Hepatic Impairment:  In a single dose study of 10 patients with mild to moderate hepatic impairment (Child-Pugh Class A and B, respectively) who were administered a single 20 mg dose of ACIPHEX delayed-release tablets, AUC0-24 was approximately doubled, the elimination half-life was 2- to 3-fold higher, and total body clearance was decreased to less than half compared to values in healthy men.

    In a multiple dose study of 12 patients with mild to moderate hepatic impairment administered 20 mg ACIPHEX delayed-release tablets once daily for eight days, AUC0-∞ and Cmax values increased approximately 20% compared to values in healthy age- and gender-matched subjects.  These increases were not statistically significant.

    No information exists on rabeprazole disposition in patients with severe hepatic impairment (Child-Pugh Class C) [see Use in Specific Populations (8.6)]. 

    Drug Interaction Studies

    Combined Administration with Antimicrobials:  Sixteen healthy subjects genotyped as extensive metabolizers with respect to CYP2C19 were given 20 mg ACIPHEX delayed-release tablets, 1000 mg amoxicillin, 500 mg clarithromycin, or all 3 drugs in a four-way crossover study.  Each of the four regimens was administered twice daily for 6 days.  The AUC and Cmax for clarithromycin and amoxicillin were not different following combined administration compared to values following single administration.  However, the rabeprazole AUC and Cmax increased by 11% and 34%, respectively, following combined administration.  The AUC and Cmax for 14-hydroxyclarithromycin (active metabolite of clarithromycin) also increased by 42% and 46%, respectively.  This increase in exposure to rabeprazole and 14-hydroxyclarithromycin is not expected to produce safety concerns.

    Effects of Other Drugs on Rabeprazole

    Antacids: Co-administration of ACIPHEX delayed-release tablets and antacids produced no clinically relevant changes in plasma rabeprazole concentrations.

    Effects of Rabeprazole on Other Drugs

    Studies in healthy subjects have shown that rabeprazole does not have clinically significant interactions with other drugs metabolized by the CYP450 system, such as theophylline (CYP1A2) given as single oral doses, diazepam (CYP2C9 and CYP3A4) as a single intravenous dose, and phenytoin (CYP2C9 and CYP2C19) given as a single intravenous dose (with supplemental oral dosing).  Steady state interactions of rabeprazole and other drugs metabolized by this enzyme system have not been studied in patients.

    Clopidogrel:  Clopidogrel is metabolized to its active metabolite in part by CYP2C19.  A study of healthy subjects including CYP2C19 extensive and intermediate metabolizers receiving once daily administration of clopidogrel 75 mg concomitantly with placebo or with 20 mg ACIPHEX delayed-release tablets (n=36), for 7 days was conducted.  The mean AUC of the active metabolite of clopidogrel was reduced by approximately 12% (mean AUC ratio was 88 %, with 90% CI of 81.7 to 95.5%) when ACIPHEX delayed-release tablets were coadministered compared to administration of clopidogrel with placebo [see Drug Interactions (7)].

    Digoxin:  In healthy adult subjects (n=16), co-administration of 20 mg rabeprazole sodium delayed-release tablets with 2.5 mg once daily doses of digoxin at steady state resulted in approximately 29% and 19% increase in mean Cmax and AUC(0-24) of digoxin [see Drug Interactions (7)].

    Ketoconazole: In healthy adult subjects (n=19), co-administration of 20 mg rabeprazole sodium delayed-release tablets at steady state with a single 400 mg oral dose ketoconazole resulted in approximately an average of 31% reduction in both Cmax and AUC(0-inf) of ketoconazole [see Drug Interactions (7)].

    Cyclosporine:  In vitro incubations employing human liver microsomes indicated that rabeprazole inhibited cyclosporine metabolism with an IC50 of 62 micromolar, a concentration that is over 50 times higher than the Cmax in healthy volunteers following 14 days of dosing with 20 mg of ACIPHEX delayed-release tablets.  This degree of inhibition is similar to that by omeprazole at equivalent concentrations.

    12.4 Microbiology

    The following in vitro data are available but the clinical significance is unknown.

    Rabeprazole sodium, amoxicillin and clarithromycin as a three drug regimen has been shown to be active against most strains of Helicobacter pylori in vitro and in clinical infections [see Indications and Usage (1), Clinical Studies (14.5)].

    Helicobacter pylori

    Susceptibility testing of H. pylori isolates was performed for amoxicillin and clarithromycin using agar dilution methodology1, and minimum inhibitory concentrations (MICs) were determined.

    Standardized susceptibility test procedures require the use of laboratory control microorganisms to control the technical aspects of the laboratory procedures.

    Incidence of Antibiotic-Resistant Organisms Among Clinical Isolates

    Pretreatment Resistance:  Clarithromycin pretreatment resistance rate (MIC ≥1 mcg/mL) to H. pylori was 9% (51/560) at baseline in all treatment groups combined.  Greater than 99% (558/560) of patients had H. pylori isolates which were considered to be susceptible (MIC ≤0.25  mcg/mL) to amoxicillin at baseline.  Two patients had baseline H. pylori isolates with an amoxicillin MIC of 0.5 mcg/mL.

    For susceptibility testing information about Helicobacter pylori, see Microbiology section in prescribing information for clarithromycin and amoxicillin.

    b Susceptible (S) MIC ≤0.25 mcg/mL, Intermediate (I) MIC = 0.5 mcg/mL, Resistant (R) MIC ≥1 mcg/mL

    Patients with persistent H. pylori infection following rabeprazole, amoxicillin, and clarithromycin therapy will likely have clarithromycin resistant clinical isolates.  Therefore, clarithromycin susceptibility testing should be done when possible.  If resistance to clarithromycin is demonstrated or susceptibility testing is not possible, alternative antimicrobial therapy should be instituted.

    Amoxicillin Susceptibility Test Results and Clinical/Bacteriological Outcomes:  In the U.S. multicenter study, greater than 99% (558/560) of patients had H. pylori isolates which were considered to be susceptible (MIC ≤0.25 mcg/mL) to amoxicillin at baseline.  The other 2 patients had baseline H. pylori isolates with an amoxicillin MIC of 0.5 mcg/mL, and both isolates were clarithromycin-resistant at baseline; in one case the H. pylori was eradicated.  In the 7- and 10-day treatment groups 75% (107/145) and 79% (112/142), respectively, of the patients who had pretreatment amoxicillin susceptible MICs (≤0.25 mcg/mL) were eradicated of H. pylori.  No patients developed amoxicillin-resistant H. pylori during therapy.

    12.5 Pharmacogenomics

    In a clinical study in evaluating ACIPHEX delayed-release tablets in Japanese adult patients categorized by CYP2C19 genotype (n=6 per genotype category), gastric acid suppression was higher in poor metabolizers as compared to extensive metabolizers.  This could be due to higher rabeprazole plasma levels in poor metabolizers.  The clinical relevance of this is not known.  Whether or not interactions of rabeprazole sodium with other drugs metabolized by CYP2C19 would be different between extensive metabolizers and poor metabolizers has not been studied.

  • 13 NONCLINICAL TOXICOLOGY

    13.1 Carcinogenesis, Mutagenesis, Impairment of Fertility

    In a 88/104-week carcinogenicity study in CD-1 mice, rabeprazole at oral doses up to 100 mg/kg/day did not produce any increased tumor occurrence.  The highest tested dose produced a systemic exposure to rabeprazole (AUC) of 1.40 µghr/mL which is 1.6 times the human exposure (plasma AUC0-∞ = 0.88 µghr/mL) at the recommended dose for GERD (20 mg/day).  In a 28-week carcinogenicity study in p53+/- transgenic mice, rabeprazole at oral doses of 20, 60, and 200 mg/kg/day did not cause an increase in the incidence rates of tumors but produced gastric mucosal hyperplasia at all doses.  The systemic exposure to rabeprazole at 200 mg/kg/day is about 17 to 24 times the human exposure at the recommended dose for GERD.  In a 104-week carcinogenicity study in Sprague-Dawley rats, males were treated with oral doses of 5, 15, 30 and 60 mg/kg/day and females with 5, 15, 30, 60, and 120 mg/kg/day.  Rabeprazole produced gastric enterochromaffin-like (ECL) cell hyperplasia in male and female rats and ECL cell carcinoid tumors in female rats at all doses including the lowest tested dose.  The lowest dose (5 mg/kg/day) produced a systemic exposure to rabeprazole (AUC) of about 0.1 µghr/mL which is about 0.1 times the human exposure at the recommended dose for GERD.  In male rats, no treatment related tumors were observed at doses up to 60 mg/kg/day producing a rabeprazole plasma exposure (AUC) of about 0.2 µghr/mL (0.2 times the human exposure at the recommended dose for GERD).

    Rabeprazole was positive in the Ames test, the Chinese hamster ovary cell (CHO/HGPRT) forward gene mutation test, and the mouse lymphoma cell (L5178Y/TK+/–) forward gene mutation test.  Its demethylated-metabolite was also positive in the Ames test.  Rabeprazole was negative in the in vitro Chinese hamster lung cell chromosome aberration test, the in vivo mouse micronucleus test, and the in vivo and ex vivo rat hepatocyte unscheduled DNA synthesis (UDS) tests.

    Rabeprazole at intravenous doses up to 30 mg/kg/day (plasma AUC of 8.8 µghr/mL, about 10 times the human exposure at the recommended dose for GERD) was found to have no effect on fertility and reproductive performance of male and female rats.

    14.1 Healing of Erosive or Ulcerative GERD in Adults

    In a U.S., multicenter, randomized, double-blind, placebo-controlled study, 103 patients were treated for up to eight weeks with placebo, 10 mg, 20 mg, or 40 mg ACIPHEX delayed-release tablets once daily.  For this and all studies of GERD healing, only patients with GERD symptoms and at least grade 2 esophagitis (modified Hetzel-Dent grading scale) were eligible for entry. Endoscopic healing was defined as grade 0 or 1.  Each rabeprazole dose was significantly superior to placebo in producing endoscopic healing after four and eight weeks of treatment.  The percentage of patients demonstrating endoscopic healing was as follows:

    In addition, there was a statistically significant difference in favor of the ACIPHEX 10 mg, 20  mg, and 40 mg doses compared to placebo at Weeks 4 and 8 regarding complete resolution of GERD heartburn frequency (p≤0.026).  All ACIPHEX groups reported significantly greater rates of complete resolution of GERD daytime heartburn severity compared to placebo at Weeks 4 and 8 (p≤0.036).  Mean reductions from baseline in daily antacid dose were statistically significant for all ACIPHEX groups when compared to placebo at both Weeks 4 and 8 (p≤0.007).  

    In a North American multicenter, randomized, double-blind, active-controlled study of 336 patients, the percentage of patients healed at endoscopy after four and eight weeks of treatment was statisticially superior in the patients treated with ACIPHEX delayed-release tablets compared to ranitidine:

    A dose of 20 mg once daily of ACIPHEX delayed-release tablets was significantly more effective than ranitidine 150 mg four times daily in the percentage of patients with complete resolution of heartburn at Weeks 4 and 8 (p<0.001).  ACIPHEX was also more effective in complete resolution of daytime heartburn (p≤0.025), and nighttime heartburn (p≤0.012) at both Weeks 4 and 8, with significant differences by the end of the first week of the study.

    The recommended dosage of ACIPHEX delayed-release tablets is 20 mg once daily for 4 to 8 weeks.

    14.2 Long-term Maintenance of Healing of Erosive or Ulcerative GERD in Adults

    The long-term maintenance of healing in patients with erosive or ulcerative GERD previously healed with gastric antisecretory therapy was assessed in two U.S., multicenter, randomized, double-blind, placebo-controlled studies of identical design of 52 weeks duration.  The two studies randomized 209 and 285 patients, respectively, to receive either 10 mg or 20 mg of ACIPHEX delayed-release tablets once daily or placebo.  As demonstrated in Tables 10 and 11 below, patients treated with ACIPHEX delayed-release tablets were significantly superior to placebo in both studies with respect to the maintenance of healing of GERD and the proportions of patients remaining free of heartburn symptoms at 52 weeks. The recommended dosage of ACIPHEX delayed-release tablets is 20 mg once daily.

    14.3 Treatment of Symptomatic GERD in Adults

    Two U.S., multicenter, double-blind, placebo controlled studies were conducted in 316 adult patients with daytime and nighttime heartburn.  Patients reported 5 or more periods of moderate to very severe heartburn during the placebo treatment phase the week prior to randomization. Patients were confirmed by endoscopy to have no esophageal erosions.

    The percentage of heartburn free daytime and/or nighttime periods was greater with 20 mg ACIPHEX delayed-release tablets compared to placebo over the 4 weeks of study in Study RAB-USA-2 (47% vs. 23%) and Study RAB-USA-3 (52% vs. 28%).  The mean decreases from baseline in average daytime and nighttime heartburn scores were significantly greater for ACIPHEX 20 mg as compared to placebo at week 4.  Graphical displays depicting the daily mean daytime and nighttime scores are provided in Figures 2 to 5.

    In addition, the combined analysis of these two studies showed 20 mg of ACIPHEX delayed-release tablets significantly improved other GERD-associated symptoms (regurgitation, belching, and early satiety) by week 4 compared with placebo (all p values <0.005).

    A dose of 20 mg ACIPHEX delayed-release tablets also significantly reduced daily antacid consumption versus placebo over 4 weeks (p<0.001).

    The recommended dosage of ACIPHEX delayed-release tablets is 20 mg once daily for 4 weeks.

    14.4 Healing of Duodenal Ulcers in Adults

    In a U.S., randomized, double-blind, multicenter study assessing the effectiveness of 20 mg and 40 mg of ACIPHEX delayed-release tablets once daily versus placebo for healing endoscopically defined duodenal ulcers, 100 patients were treated for up to four weeks.  ACIPHEX was significantly superior to placebo in producing healing of duodenal ulcers.  The percentages of patients with endoscopic healing are presented below:

    * p≤0.001 versus placebo

    At Weeks 2 and 4, significantly more patients in the ACIPHEX 20 and 40 mg groups reported complete resolution of ulcer pain frequency (p≤0.018), daytime pain severity (p≤0.023), and nighttime pain severity (p≤0.035) compared with placebo patients.  The only exception was the 40 mg group versus placebo at Week 2 for duodenal ulcer pain frequency (p=0.094).  Significant differences in resolution of daytime and nighttime pain were noted in both ACIPHEX groups relative to placebo by the end of the first week of the study.  Significant reductions in daily antacid use were also noted in both ACIPHEX groups compared to placebo at Weeks 2 and 4 (p<0.001).

    An international randomized, double-blind, active-controlled trial was conducted in 205 patients comparing 20 mg ACIPHEX delayed-release tablets once daily with 20 mg omeprazole once daily.  The study was designed to provide at least 80% power to exclude a difference of at least 10% between ACIPHEX and omeprazole, assuming four-week healing response rates of 93% for both groups.  In patients with endoscopically defined duodenal ulcers treated for up to four weeks, ACIPHEX was comparable to omeprazole in producing healing of duodenal ulcers.  The percentages of patients with endoscopic healing at two and four weeks are presented below:

    ACIPHEX and omeprazole were comparable in providing complete resolution of symptoms.

    The recommended dosage of ACIPHEX delayed-release tablets is 20 mg once daily for 4 weeks.

    14.5 Helicobacter pylori Eradication in Patients with Peptic Ulcer Disease or Symptomatic Non-Ulcer Disease in Adults

    The U.S. multicenter study was a double-blind, parallel-group comparison of ACIPHEX delayed-release tablets, amoxicillin, and clarithromycin for 3, 7, or 10 days vs. omeprazole, amoxicillin, and clarithromycin for 10 days.  Therapy consisted of rabeprazole 20 mg twice daily, amoxicillin 1000 mg twice daily, and clarithromycin 500 mg twice daily (RAC) or omeprazole 20 mg twice daily, amoxicillin 1000 mg twice daily, and clarithromycin 500 mg twice daily (OAC).  Patients with H. pylori infection were stratified in a 1:1 ratio for those with peptic ulcer disease (active or a history of ulcer in the past five years) [PUD] and those who were symptomatic but without peptic ulcer disease [NPUD], as determined by upper gastrointestinal endoscopy.  The overall H. pylori eradication rates, defined as negative 13C-UBT for H. pylori ≥6 weeks from the end of the treatment are shown in the following table.  The eradication rates in the 7-day and 10-day RAC regimens were found to be similar to 10-day OAC regimen using either the Intent-to-Treat (ITT) or Per-Protocol (PP) populations.  Eradication rates in the RAC 3-day regimen were inferior to the other regimens.

    a Patients were included in the analysis if they had H. pylori infection documented at baseline, defined as a positive 13C-UBT plus rapid urease test or culture and were not protocol violators.  Patients who dropped out of the study due to an adverse event related to the study drug were included in the evaluable analysis as failures of therapy.
    b Patients were included in the analysis if they had documented H. pylori infection at baseline as defined above and took at least one dose of study medication.  All dropouts were included as failures of therapy.
    * The 95% confidence intervals for the difference in eradication rates for 7-day RAC minus 10-day RAC are (- 9.3, 6.0) in the PP population and (-9.0, 7.5) in the ITT population.

    The recommended dosage of ACIPHEX delayed-release tablets is 20 mg twice daily with amoxicillin and clarithromycin for 7 days.

    14.6 Pathological Hypersecretory Conditions, Including Zollinger-Ellison Syndrome in Adults

    Twelve patients with idiopathic gastric hypersecretion or Zollinger-Ellison syndrome have been treated successfully with ACIPHEX delayed-release tablets at doses from 20 to 120 mg for up to 12 months.  ACIPHEX produced satisfactory inhibition of gastric acid secretion in all patients and complete resolution of signs and symptoms of acid-peptic disease where present.  ACIPHEX also prevented recurrence of gastric hypersecretion and manifestations of acid-peptic disease in all patients.  The high doses of ACIPHEX used to treat this small cohort of patients with gastric hypersecretion were well tolerated.

    The recommended starting dosage of ACIPHEX delayed-release tablets is 60 mg once daily.

  • MEDICATION GUIDE

    MEDICATION GUIDE
    ACIPHEX® (a-se-feks)
    (rabeprazole sodium)
    delayed-release tablets
    Read the Medication Guide that comes with ACIPHEX before you start taking it and each time you get a refill. There may be new information. This Medication Guide does not take the place of talking to your doctor about your medical condition or treatment.
    What is the most important information I should know about ACIPHEX?
    ACIPHEX may help your acid-related symptoms, but you could still have serious stomach problems. Talk with your doctor.
    ACIPHEX can cause serious side effects, including:
    • Diarrhea. ACIPHEX may increase your risk of getting severe diarrhea. This diarrhea may be caused by an infection (Clostridium difficile) in your intestines.
      Call your doctor right away if you have watery stool, stomach pain, and fever that does not go away. 
    • Bone fractures.  People who take multiple daily doses of Proton Pump Inhibitor (PPI) medicines for a long period of time (1 year or longer) may have an increased risk of fractures of the hip, wrist, or spine. You should take ACIPHEX exactly as prescribed, at the lowest dose possible for your treatment and for the shortest time needed. Talk to your doctor about your risk of bone fracture if you take ACIPHEX.  
    ACIPHEX can have other serious side effects. See “What are the possible side effects of ACIPHEX?”
    What is ACIPHEX?
    ACIPHEX is a prescription medicine called a Proton Pump Inhibitor (PPI).
    ACIPHEX reduces the amount of acid in your stomach.
    ACIPHEX is used in adults:
    • for up to 8 weeks to heal acid-related damage to the lining of the esophagus (called erosive esophagitis or EE) and to relieve symptoms, such as heartburn pain. If needed, your doctor may decide to prescribe another 8 weeks of ACIPHEX.
    • to maintain the healing of the esophagus and relief of symptoms related to EE. It is not known if ACIPHEX is safe and effective if used longer than 12 months (1 year).
    • for up to 4 weeks to treat daytime and nighttime heartburn and other symptoms that happen with Gastroesophageal Reflux Disease (GERD).
      GERD happens when acid in your stomach backs up into the tube (esophagus) that connects your mouth to your stomach. This may cause a burning feeling in your chest or throat, sour taste, or burping.
    • for up to 4 weeks for the healing and relief of duodenal ulcers. The duodenal area is the area where food passes when it leaves the stomach.
    • for 7 days with certain antibiotic medicines to treat an infection caused by bacteria called H. pylori. Sometimes H. pylori bacteria can cause duodenal ulcers. The infection needs to be treated to prevent the ulcers from coming back.
    • for the long-term treatment of conditions where your stomach makes too much acid. This includes a rare condition called Zollinger-Ellison syndrome.
    ACIPHEX is used in adolescents 12 years of age and older to treat symptoms of Gastroesophageal Reflux Disease (GERD) for up to 8 weeks.
    It is not known if ACIPHEX is safe and effective in children to:
    • heal acid-related damage to the lining of the esophagus (called erosive esophagitis or EE)
    • maintain the healing of the esophagus and relief of symptoms related to EE
    • treat symptoms that happen with Gastroesophageal Reflux Disease (GERD)
    • heal duodenal ulcers
    • treat an infection caused by bacteria called H. pylori to reduce the risk of duodenal ulcers from coming back
    • treat conditions where your stomach makes too much acid, including Zollinger-Ellison Syndrome.
    ACIPHEX delayed-release tablets should not be used in children under 12 years of age.
    Who should not take ACIPHEX?
    Do not take ACIPHEX if you:
    • are allergic to rabeprazole or any of the other ingredients in ACIPHEX. See the end of this Medication Guide for a complete list of ingredients in ACIPHEX.
    • are allergic to any other Proton Pump Inhibitor (PPI) medicine
    • are taking a medicine that contains rilpivirine (Edurant, Complera) used to treat HIV-1 (Human Immunodeficiency Virus)
    What should I tell my doctor before taking ACIPHEX?
    Before you take ACIPHEX tell your doctor if you:
    • have been told that you have low magnesium levels in your blood
    • have liver problems
    • have any allergies
    • have any other medical conditions
    • are pregnant or plan to become pregnant. It is not known if ACIPHEX can harm your unborn baby. Talk to your doctor about the possible risks to an unborn baby if ACIPHEX is taken during pregnancy.
    • are breastfeeding or plan to breastfeed. It is not known if ACIPHEX passes into your breast milk or if it will affect your baby or your breast milk. Talk to your doctor about the best way to feed your baby if you take ACIPHEX.
    Tell your doctor about all the medicines you take, including prescription and over-the-counter medicines, vitamins, and herbal supplements. ACIPHEX may affect how other medicines work, and other medicines may affect how ACIPHEX works.  Especially tell your doctor if you take an antibiotic that contains clarithromycin or amoxicillin or if you take warfarin (COUMADIN, JANTOVEN) or methotrexate (Otrexup, Rasuvo, Trexall).
    Know the medicines that you take. Keep a list of them to show your doctor and pharmacist when you get a new medicine.
    How should I take ACIPHEX?
    • Take ACIPHEX exactly as prescribed. Your doctor will prescribe the dose that is right for you and your medical condition. Do not change your dose or stop taking ACIPHEX unless you talk to your doctor. Take ACIPHEX for as long as it is prescribed even if you feel better.
    • ACIPHEX is usually taken 1 time each day. Your doctor will tell you the time of day to take ACIPHEX, based on your medical condition.
    • ACIPHEX can be taken with or without food. Your doctor will tell you whether to take this medicine with or without food based on your medical condition.
    • Swallow each ACIPHEX tablet whole. Do not chew, crush, or split ACIPHEX tablets. Tell your doctor if you cannot swallow tablets whole.
    • If you miss a dose of ACIPHEX, take it as soon as possible. If it is almost time for your next dose, skip the missed dose and go back to your normal schedule. Do not take 2 doses at the same time.
    • If you take too much ACIPHEX, call your doctor or your poison control center at 1-800-222-1222 right away, or go to the nearest hospital emergency room.
    • Your doctor may prescribe antibiotic medicines with ACIPHEX to help treat a stomach infection and heal stomach (duodenal) ulcers that are caused by bacteria called H. pylori. Make sure you read the patient information that comes with an antibiotic before you start taking it. 
    What are the possible side effects of ACIPHEX?
    ACIPHEX may cause serious side effects, including:
    • See “What is the most important information I should know about ACIPHEX?”
    • Interaction with warfarin. Taking warfarin with a Proton Pump Inhibitor (PPI) may lead to an increased risk of bleeding and death. If you take warfarin, your doctor may check your blood to see if you have an increased risk of bleeding.  If you take warfarin during treatment with ACIPHEX, tell your doctor right away if you have any signs or symptoms of bleeding, including:
      ° unexpected bleeding or bleeding that lasts a long time, such as:
       ▪ nosebleeds that happen often
       ▪ unusual bleeding from the gums
       ▪ menstrual bleeding that is heavier than normal or unusual vaginal bleeding
       ▪ bleeding that is severe or that you cannot control
      ° red, pink or brown urine
      ° bright red or black stools (looks like tar)
      ° coughing up blood or blood clots
      ° vomiting blood or your vomit looks like “coffee grounds”
      ° headaches
      ° feel dizzy or weak
    • Vitamin B-12 deficiency.  ACIPHEX reduces the amount of acid in your stomach. Stomach acid is needed to absorb vitamin B-12 properly. Talk with your doctor about the possibility of vitamin B-12 deficiency if you have been on ACIPHEX for a long time (more than 3 years).
    • Low magnesium levels in your body. This problem can be serious. Low magnesium can happen in some people who take a Proton Pump inhibitor (PPI) medicine for at least 3 months. If low magnesium levels happen, it is usually after a year of treatment. You may or may not have symptoms of low magnesium.
    Tell your doctor right away and get medical care if you have any of these symptoms:
    • seizures
    • dizziness
    • abnormal or fast heart beat
    • jitteriness
    • jerking movements or shaking (tremors)
    • muscle weakness
    • spasms of the hands and feet
    • cramps or muscle aches
    • spasm of the voice box
    Your doctor may check the level of magnesium in your body before you start taking ACIPHEX, during treatment, or if you will be taking ACIPHEX for a long period of time.
    The most common side effects of ACIPHEX in adults include:
    • pain
    • sore throat
    • gas
    • infection
    • constipation
    The most common side effects of ACIPHEX in adolescents 12 years of age and older include:
