Drug Details [pdf]

  • 1 INDICATIONS AND USAGE

    1.1 Duodenal Ulcer


    Omeprazole and sodium bicarbonate capsules are indicated for short-term treatment of active duodenal ulcer. Most patients heal within four weeks. Some patients may require an additional four weeks of therapy. [See Clinical Studies (14.1)]

    1.2 Gastric Ulcer


    Omeprazole and sodium bicarbonate capsules are indicated for short-term treatment (4 to 8 weeks) of active benign gastric ulcer. [See Clinical Studies (14.2)]

    1.3 Treatment of Gastroesophageal Reflux Disease (GERD)

    Symptomatic GERD

    Omeprazole and sodium bicarbonate capsules are indicated for the treatment of heartburn and other symptoms associated with GERD. [See Clinical Studies (14.3)]

    Erosive Esophagitis

    Omeprazole and sodium bicarbonate capsules are indicated for the short-term treatment (4 to 8 weeks) of erosive esophagitis which has been diagnosed by endoscopy.

    The efficacy of omeprazole and sodium bicarbonate used for longer than 8 weeks in these patients has not been established. If a patient does not respond to 8 weeks of treatment, it may be helpful to give up to an additional 4 weeks of treatment. If there is recurrence of erosive esophagitis or GERD symptoms (e.g., heartburn), additional 4 to 8 week courses of omeprazole and sodium bicarbonate may be considered. [See Clinical Studies (14.3)]

    1.4 Maintenance of Healing of Erosive Esophagitis


    Omeprazole and sodium bicarbonate capsules are indicated to maintain healing of erosive esophagitis. Controlled studies do not extend beyond 12 months. [See Clinical Studies (14.4)]

  • 2 DOSAGE AND ADMINISTRATION


    Omeprazole and sodium bicarbonate is available as a capsule in 20 mg and 40 mg strengths of omeprazole for adult use. Directions for use for each indication are summarized in Table 1.


    All recommended doses throughout the labeling are based upon omeprazole.


    Since both the 20 mg and 40 mg capsules contain the same amount of sodium bicarbonate (1100 mg), two capsules of 20 mg are notequivalent to one capsule of omeprazole and sodium bicarbonate 40 mg; therefore, two 20 mg capsules of omeprazole and sodium bicarbonate should not be substituted for one capsule of omeprazole and sodium bicarbonate 40 mg.

    Omeprazole and sodium bicarbonate capsules should be taken on an empty stomach at least one hour before a meal.

  • 3 DOSAGE FORMS AND STRENGTHS


    Omeprazole and Sodium Bicarbonate Capsules, 20 mg/1100 mg: each hard gelatin capsule has a light blue opaque cap and white opaque body, imprinted in black ink with ‘U’ on the cap, ‘88’ on the body and contains 20 mg omeprazole, USP and 1100 mg sodium bicarbonate, USP.


    Omeprazole and Sodium Bicarbonate Capsules, 40 mg/1100 mg: each hard gelatin capsule has a dark blue opaque cap and white opaque body, imprinted in black ink with ‘U’ on the cap, ‘89’ on the body and contains 40 mg omeprazole, USP and 1100 mg sodium bicarbonate, USP.

  • 4 CONTRAINDICATIONS


    Omeprazole and sodium bicarbonate is contraindicated in patients with known hypersensitivity to any components of the formulation. Hypersensitivity reactions may include anaphylaxis, anaphylactic shock, angioedema, bronchospasm, interstitial nephritis, and urticaria. [See Adverse Reactions (6)]


  • 5 WARNINGS AND PRECAUTIONS

    5.1 Concomitant Gastric Malignancy


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

    5.2 Atrophic gastritis


    Atrophic gastritis has been noted occasionally in gastric corpus biopsies from patients treated long-term with omeprazole.

    5.3 Acute Interstitial Nephritis

    Acute interstitial nephritis has been observed in patients taking PPIs including omeprazole and sodium bicarbonate. Acute interstitial nephritis may occur at any point during PPI therapy and is generally attributed to an idiopathic hypersensitivity reaction. Discontinue omeprazole and sodium bicarbonate 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.

    5.5 Buffer Content

    Each omeprazole and sodium bicarbonate capsule contains 1100 mg (13 mEq) of sodium bicarbonate. The total content of sodium in each capsule is 304 mg.


    The sodium content of omeprazole and sodium bicarbonate capsules should be taken into consideration when administering to patients on a sodium restricted diet.


    Because omeprazole and sodium bicarbonate capsules contain sodium bicarbonate, they should be used with caution in patients with Bartter’s syndrome, hypokalemia, hypocalcemia, and problems with acid-base balance. Long-term administration of bicarbonate with calcium or milk can cause milk-alkali syndrome.


    Chronic use of sodium bicarbonate may lead to systemic alkalosis and increased sodium intake can produce edema and weight increase.

    5.6 Clostridium difficile Associated Diarrhea

    Published observational studies suggest that PPI therapy like omeprazole and sodium bicarbonate 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.

    5.7 Interaction with Clopidogrel

    Avoid concomitant use of omeprazole and sodium bicarbonate with clopidogrel. Clopidogrel is a prodrug. Inhibition of platelet aggregation by clopidogrel is entirely due to an active metabolite. The metabolism of clopidogrel to its active metabolite can be impaired by use with concomitant medications, such as omeprazole, that interfere with CYP2C19 activity. Concomitant use of clopidogrel with 80 mg omeprazole reduces the pharmacological activity of clopidogrel, even when administered 12 hours apart. When using omeprazole and sodium bicarbonate, consider alternative anti-platelet therapy. [See Drug Interactions (7.5) and Pharmacokinetics (12.3)]

    5.8 Bone Fracture


    Several published observational studies suggest that proton pump inhibitor (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 the established treatment guidelines. [See Dosage and Administration (2) and Adverse Reactions (6.2)]

    5.9 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), health care professionals may consider monitoring magnesium levels prior to initiation of PPI treatment and periodically.[See Adverse Reactions (6.2)]

    5.10 Concomitant Use of Omeprazole and Sodium Bicarbonate with St John's

    Drugs which induce CYP2C19 OR CYP34A (such as St John's Wort or rifampin) can substantially decrease omeprazole concentrations [See Drug Interactions (7.2)].Avoid concomitant use of omeprazole and sodium bicarbonate with St John's Wort or rifampin.

    5.11 Interactions with Investigations for Neuroendocrine Tumors

    Serum chromogranin A (CgA) levels increase secondary to drug-induced decreases in gastric acidity. The increased CgA level may cause false positive results in diagnostic investigations for neuroendocrine tumors. Providers should temporarily stop omeprazole treatment before assessing CgA levels and consider repeating the test if initial CgA levels are high. If serial tests are performed (e.g. for monitoring), the same commercial laboratory should be used for testing, as reference ranges between tests may vary. [See Pharmacodynamics (12.2)].

    5.12 Concomitant use of Omeprazole and Sodium Bicarbonate with Methotrexate


    Literature suggests that concomitant use of PPIs with methotrexate (primarily at high dose; see methotrexate prescribing information) may elevate and prolong serum levels 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 (7.8)].

  • 6 ADVERSE REACTIONS

    6.1 Clinical Trials Experience

    Because clinical trials are conducted under widely 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 clinical practice.

    In the U.S. clinical trial population of 465 patients, the adverse reactions summarized in Table 2 were reported to occur in 1% or more of patients on therapy with omeprazole. Numbers in parentheses indicate percentages of the adverse reactions considered by investigators as possibly, probably or definitely related to the drug.

    6.2 Postmarketing Experience


    The following adverse reactions have been identified during post-approval use of omeprazole. Because these reactions are voluntarily reported from a population of uncertain size, it is not always possible to reliably estimate their actual frequency or establish a causal relationship to drug exposure.


    Body as a Whole:Hypersensitivity reactions, including anaphylaxis, anaphylactic shock, angioedema, bronchospasm, interstitial nephritis, urticaria (see also Skinbelow), fever, pain, fatigue, malaise.


    Cardiovascular:Chest pain or angina, tachycardia, bradycardia, palpitation, elevated blood pressure, and peripheral edema.


    Gastrointestinal:Pancreatitis (some fatal), anorexia, irritable colon, flatulence, fecal discoloration, esophageal candidiasis, mucosal atrophy of the tongue, dry mouth, stomatitis and abdominal swelling. During treatment with omeprazole, gastric fundic gland polyps have been noted rarely. These polyps are benign and appear to be reversible when treatment is discontinued. Gastroduodenal carcinoids have been reported in patients with Zollinger-Ellison syndrome on long-term treatment with omeprazole. This finding is believed to be a manifestation of the underlying condition, which is known to be associated with such tumors.


    Hepatic:Mild and, rarely, marked elevations of liver function tests [ALT (SGPT), AST (SGOT), γ-glutamyl transpeptidase, alkaline phosphatase, and bilirubin (jaundice)]. In rare instances, overt liver disease has occurred, including hepatocellular, cholestatic, or mixed hepatitis, liver necrosis (some fatal), hepatic failure (some fatal), and hepatic encephalopathy.


    Infections and Infestations: Clostridium difficile associated diarrhea.

     

    Metabolism and Nutritional Disorders:Hyponatremia, hypoglycemia, hypomagnesemia, and weight gain.


    Musculoskeletal:Muscle cramps, myalgia, muscle weakness, joint pain, bone fracture, and leg pain.


    Nervous System/Psychiatric: Psychic disturbances including depression, agitation, aggression, hallucinations, confusion, insomnia, nervousness, tremors, apathy, somnolence, anxiety, dream abnormalities; vertigo; paresthesia; and hemifacial dysesthesia.


    Respiratory:Epistaxis, pharyngeal pain.


    Skin:Severe generalized skin reactions including toxic epidermal necrolysis (TEN; some fatal), Stevens-Johnson syndrome, and erythema multiforme (some severe); purpura and/or petechiae (some with rechallenge); skin inflammation, urticaria, angioedema, pruritus, photosensitivity, alopecia, dry skin, and hyperhidrosis.


    Special Senses:Tinnitus, taste perversion.


    Ocular:Blurred vision, ocular irritation, dry eye syndrome, optic atrophy, anterior ischemic optic neuropathy, optic neuritis and double vision.


    Urogenital: Interstitial nephritis (some with positive rechallenge), urinary tract infection, microscopic pyuria, urinary frequency, elevated serum creatinine, proteinuria, hematuria, glycosuria, testicular pain, and gynecomastia.


    Hematologic:Rare instances of pancytopenia, agranulocytosis (some fatal), thrombocytopenia, neutropenia, leukopenia, anemia, leucocytosis, and hemolytic anemia have been reported.


    The incidence of clinical adverse experiences in patients greater than 65 years of age was similar to that in patients 65 years of age or less.

    Additional adverse reactions that could be caused by sodium bicarbonate include metabolic alkalosis, seizures, and tetany.

  • 7 DRUG INTERACTIONS

    7.1 Drugs for which gastric pH can affect bioavailability


    Due to its effects on gastric acid secretion, omeprazole can reduce the absorption of drugs where gastric pH is an important determinant of their bioavailability.  Like with other drugs that decrease the intragastric acidity, the absorption of drugs such as ketoconazole, atazanavir, iron salts, erlotinib, and mycophenolate mofetil (MMF) can decrease, while the absorption of drugs such as digoxin can increase during treatment with omeprazole.


    Concomitant treatment with omeprazole (20 mg daily) and digoxin in healthy subjects increased the bioavailability of digoxin by 10% (30% in two subjects). Coadministration of digoxin with omeprazole and sodium bicarbonate is expected to increase the systemic exposure of digoxin. Therefore, patients may need to be monitored when digoxin is taken concomitantly with omeprazole and sodium bicarbonate.


    Co-administration of omeprazole 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 omeprazole and sodium bicarbonate and MMF. Use omeprazole and sodium bicarbonate with caution in transplant patients receiving MMF. [See Clinical Pharmacology (12.3)]

    7.2 Drugs metabolized by cytochrome P450 (CYP)


    Omeprazole can prolong the elimination of diazepam, warfarin and phenytoin, drugs that are metabolized by oxidation in the liver. There have been reports of increased INR and prothrombin time in patients receiving proton pump inhibitors, including omeprazole, and warfarin concomitantly. Increases in INR and prothrombin time may lead to abnormal bleeding and even death. Patients treated with proton pump inhibitors and warfarin may need to be monitored for increases in INR and prothrombin time.


    Although in normal subjects no interaction with theophylline or propranolol was found, there have been clinical reports of interaction with other drugs metabolized via the cytochrome P-450 system (e.g., cyclosporine, disulfiram, benzodiazepines). Patients should be monitored to determine if it is necessary to adjust the dosage of these drugs when taken concomitantly with omeprazole and sodium bicarbonate.


    Concomitant administration of omeprazole and voriconazole (a combined inhibitor of CYP2C19 and CYP3A4) resulted in more than doubling of the omeprazole exposure. Dose adjustment of omeprazole is not normally required. When voriconazole (400 mg every 12 hours for one day, then 200 mg for 6 days) was given with omeprazole (40 mg once daily for 7 days) to healthy subjects, it significantly increased the steady-state Cmax and AUC0-24 of omeprazole, an average of 2 times (90% CI: 1.8, 2.6) and 4 times (90% CI: 3.3, 4.4) respectively as compared to when omeprazole was given without voriconazole.


    Drugs known to induce CYP2C19 or CYP3A4 (such as rifampin) may lead to decreased omeprazole serum levels. In a cross-over study in 12 healthy male subjects, St John's wort (300 mg three times daily for 14 days), an inducer of CYP3A4, decreased the systemic exposure of omeprazole in CYP2C19 poor metabolisers (Cmax and AUC decreased by 37.5% and 37.9%, respectively) and extensive metabolisers (Cmax and AUC decreased by 49.6% and 43.9%, respectively). Avoid concomitant use of St. John's Wort or rifampin with omeprazole.

    7.3 Antiretroviral Agents


    Concomitant administration of atazanavir and proton pump inhibitors is not recommended. Co-administration of atazanavir with proton pump inhibitors is expected to substantially decrease atazanavir plasma concentrations and thereby reduce its therapeutic effect.


    Omeprazole has been reported to interact with some antiretroviral drugs. The clinical importance and the mechanisms behind these interactions are not always known. Increased gastric pH during omeprazole treatment may change the absorption of the antiretroviral drug. Other possible interaction mechanisms are via CYP2C19. For some antiretroviral drugs, such as atazanavir and nelfinavir, decreased serum levels have been reported when given together with omeprazole. Following multiple doses of nelfinavir (1250 mg, twice daily) and omeprazole (40 mg, daily), AUC was decreased by 36% and 92%, Cmax by 37% and 89% and Cmin by 39% and 75% respectively for nelfinavir and M8. Following multiple doses of atazanavir (400 mg, daily) and omeprazole (40 mg, daily, 2 hours before atazanavir), AUC was decreased by 94%, Cmax by 96%, and Cmin by 95%. Concomitant administration with omeprazole and drugs such as atazanavir and nelfinavir is therefore not recommended.


    Increased Concentration of Saquinavir

    For other antiretroviral drugs, such as saquinavir, elevated serum levels have been reported with an increase in AUC by 82%, in Cmax by 75% and in Cmin by 106% following multiple dosing of saquinavir/ritonavir (1000/100 mg) twice daily for 15 days with omeprazole 40 mg daily co-administered days 11 to 15. Dose reduction of saquinavir should be considered from the safety perspective for individual patients. There are also some antiretroviral drugs of which unchanged serum levels have been reported when given with omeprazole.

    7.4 Combination Therapy with Clarithromycin

    Concomitant administration of clarithromycin with other drugs can lead to serious adverse reactions due to drug interaction [See Warnings and Precautions in prescribing information for clarithromycin]. Because of these drug interactions, clarithromycin is contraindicated for co-administration with certain drugs. [See Contraindications in prescribing information for clarithromycin]

    7.5 Clopidogrel


    Omeprazole is an inhibitor of CYP2C19 enzyme. Clopidogrel is metabolized to its active metabolite in part by CYP2C19. Concomitant use of omeprazole80 mg results in reduced plasma concentrations of the active metabolite of clopidogrel and a reduction in platelet inhibition. Avoid concomitant administration of omeprazole and sodium bicarbonate with clopidogrel. When using omeprazole and sodium bicarbonate, consider use of alternative anti-platelet therapy. [See Pharmacokinetics (12.3)]

    7.6 Tacrolimus


    Concomitant administration of omeprazole and tacrolimus may increase the serum levels of tacrolimus.

    7.7 Interactions With Investigations of Neuroendocrine Tumors

    Drug-induced decrease in gastric acidity results in enterochromaffin-like cell hyperplasia and increased Chromogranin A levels which may interfere with investigations for neuroendocrine tumors. [See Clinical Pharmacology (12)].


    7.8 Methotrexate


    Case reports, published population pharmacokinetic studies, and retrospective analyses suggest that concomitant administration of PPIs and methotrexate (primarily at high dose; see methotrexate prescribing information) may elevate and prolong serum levels of methotrexate and/or its metabolite hydroxymethotrexate. However, no formal drug interaction studies of methotrexate with PPIs have been conducted. [See Warnings and Precautions (5.12)].


  • 8 USE IN SPECIFIC POPULATIONS

    8.1 Pregnancy


    Pregnancy Category C

    Risk Summary

    There are no adequate and well-controlled studies on the use of omeprazole and sodium bicarbonate in pregnant women. Available epidemiologic data fail to demonstrate an increased risk of major congenital malformations or other adverse pregnancy outcomes with first trimester omeprazole use. Teratogenicity was not observed in animal reproduction studies with administration of oral esomeprazole magnesium in rats and rabbits with doses about68 times and 42 times, respectively, an oral human dose of 40 mg (based on a body surface area basis for a 60 kg person). However, changes in bone morphology were observed in offspring of rats dosed through most of pregnancy and lactation at doses equal to or greater than approximately 33.6 times an oral human dose of 40 mg (see Animal Data).  Because of the observed effect at high doses of esomeprazole magnesium on developing bone in rat studies, omeprazole and sodium bicarbonate should be used during pregnancy only if the potential benefit justifies the potential risk to the fetus.


    Human Data

    Four published epidemiological studies compared the frequency of congenital abnormalities among infants born to women who used omeprazole during pregnancy with the frequency of abnormalities among infants of women exposed to H2-receptor antagonists or other controls.


    A population-based retrospective cohort epidemiological study from the Swedish Medical Birth Registry, covering approximately 99% of pregnancies, from 1995-99, reported on 955 infants (824 exposed during the first trimester with 39 of these exposed beyond first trimester, and 131 exposed after the first trimester) whose mothers used omeprazole during pregnancy. The number of infants exposed in utero to omeprazole that had any malformation, low birth weight, low Apgar score, or hospitalization was similar to the number observed in this population. The number of infants born with ventricular septal defects and the number of stillborn infants was slightly higher in the omeprazole-exposed infants than the expected number in this population.


    A population-based retrospective cohort study covering all live births in Denmark from 1996-2009, reported on 1,800 live births whose mothers used omeprazole during the first trimester of pregnancy and 837, 317 live births whose mothers did not use any proton pump inhibitor. The overall rate of birth defects in infants born to mothers with first trimester exposure to omeprazole was 2.9% and 2.6% in infants born to mothers not exposed to any proton pump inhibitor during the first trimester.


    A retrospective cohort study reported on 689 pregnant women exposed to either H2-blockers or omeprazole in the first trimester (134 exposed to omeprazole) and 1,572 pregnant women unexposed to either during the first trimester.  The overall malformation rate in offspring born to mothers with first trimester exposure to omeprazole, an H2-blocker, or were unexposed was 3.6%, 5.5%, and 4.1% respectively.


    A small prospective observational cohort study followed 113 women exposed to omeprazole during pregnancy (89% first trimester exposures).  The reported rate of major congenital malformations was 4% in the omeprazole group, 2% in controls exposed to non-teratogens, and 2.8% in disease-paired controls.  Rates of spontaneous and elective abortions, preterm deliveries, gestational age at delivery, and mean birth weight were similar among the groups.


    Several studies have reported no apparent adverse short-term effects on the infant when single dose oral or intravenous omeprazole was administered to over 200 pregnant women as premedication for cesarean section under general anesthesia.


    Animal Data

    Reproductive studies conducted with omeprazole in rats at oral doses up to 138 mg/kg/day (about 33.6 times an oral human dose of 40 mg on a body surface area basis) and in rabbits at doses up to 69 mg/kg/day (about 33.6times an oral human dose of 40 mg on a body surface area basis) did not disclose any evidence for a teratogenic potential of omeprazole. In rabbits, omeprazole in a dose range of 6.9 to 69.1 mg/kg/day (about 3.36 to 33.6 times an oral human dose of 40 mg on a body surface area basis) produced dose-related increases in embryo-lethality, fetal resorptions, and pregnancy disruptions. In rats, dose-related embryo/fetal toxicity and postnatal developmental toxicity were observed in offspring resulting from parents treated with omeprazole at 13.8 to 138.0 mg/kg/day (about 3.36 to 33.6 times an oral human dose of 40 mg on a body surface area basis).


    Reproduction studies have been performed with esomeprazole magnesium in rats at oral doses up to 280 mg/kg/day (about 68 times an oral human dose of 40 mg on a body surface area basis) and in rabbits at oral doses up to 86 mg/kg/day (about42 times an oral human dose of 40 mg on a body surface area basis) and have revealed no evidence of impaired fertility or harm to the fetus due to esomeprazole magnesium.


    A pre- and postnatal developmental toxicity study in rats with additional endpoints to evaluate bone development were performed with the S- enantiomer, esomeprazole magnesium at oral doses of 14 to 280 mg/kg/day (about 3.4 to 68 times an oral human dose of 40 mg of esomeprazole on a body surface area basis).   Neonatal/early postnatal (birth to weaning) survival was decreased at doses equal to or greater than 138 mg/kg/day (about 33.6 times an oral human dose of 40 mg on a body surface area basis). Body weight and body weight gain were reduced and neurobehavioral or general developmental delays in the immediate post-weaning timeframe were evident at doses equal to or greater than 69 mg /kg/day (about 16.8 times an oral human dose of 40 mg on a body surface area basis). In addition, 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 esomeprazole magnesium equal to or greater than 14 mg/kg/day (about 3.4 times an oral human dose of 40 mg on a body surface area basis). Physeal dysplasia in the femur was observed in offspring of rats treated with oral doses of esomeprazole magnesium at doses equal to or greater than 138 mg/kg/day (about 33.6 times an oral human dose of 40 mg 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 esomeprazole magnesium was administered at oral doses of 14 to 280 mg/kg/day (about 3.4 to 68 times an oral human dose of 40 mg 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 of esomeprazole magnesium equal to or greater than 138 mg/kg/day (about 33.6 times an oral human dose of 40 mg on a body surface area basis).


    A pre- and post natal development study in rats with esomeprazole strontium (using equimolar doses compared to esomeprazole magnesium study) produced similar results in dams and pups as described above.

    8.3 Nursing Mothers


    Omeprazole concentrations have been measured in breast milk of a woman following oral administration of 20 mg. The peak concentration of omeprazole in breast milk was less than 7% of the peak serum concentration.


    The concentration will correspond to 0.004 mg of omeprazole in 200 mL of milk. Because omeprazole is excreted in human milk, because of the potential for serious adverse reactions in nursing infants from omeprazole, and because of the potential for tumorigenicity shown for omeprazole in rat carcinogenicity studies, a decision should be made to discontinue nursing or to discontinue the drug, taking into account the importance of the drug to the mother. In addition, sodium bicarbonate should be used with caution in nursing mothers.

    8.4 Pediatric Use


    Safety and effectiveness of omeprazole and sodium bicarbonate have not been established in pediatric patients less than 18 years of age.


    Juvenile Animal Data

    In a juvenile rat toxicity study, esomeprazole was administered with both magnesium and strontium salts at oral doses about 34 to 68 times a daily human dose of 40 mg on a body surface area basis.  Increases in death were seen at the high dose, and at all doses of esomeprazole, there were decreases in body weight, body weight gain, femur weight and femur length, and decreases in overall growth. [See Nonclinical Toxicology (13.2)]


    8.5 Geriatric Use



    Omeprazole was administered to over 2000 elderly individuals (≥ 65 years of age) in clinical trials in the U.S. and Europe. There were no differences in safety and effectiveness between the elderly and younger subjects. Other reported clinical experience has not identified differences in response between the elderly and younger subjects, but greater sensitivity of some older individuals cannot be ruled out.


    Pharmacokinetic studies with buffered omeprazole have shown the elimination rate was somewhat decreased in the elderly and bioavailability was increased. The plasma clearance of omeprazole was 250 mL/min (about half that of young subjects). The plasma half-life averaged one hour, about twice that in nonelderly, healthy subjects taking omeprazole and sodium bicarbonate. However, no dosage adjustment is necessary in the elderly. [See Clinical Pharmacology(12.3)]

    8.6 Hepatic Impairment


    Consider dose reduction, particularly for maintenance of healing of erosive esophagitis. [See Clinical Pharmacology (12.3)]

    8.7 Renal Impairment


    No dose reduction is necessary. [See Clinical Pharmacology (12.3)]

    8.8 Asian Population


    Recommended dose reduction, particularly for maintenance of healing of erosive esophagitis. [See Clinical Pharmacology (12.3)]

  • 10 OVERDOSAGE



    Reports have been received of overdosage with omeprazole in humans. Doses ranged up to 2400 mg (120 times the usual recommended clinical dose). Manifestations were variable, but included confusion, drowsiness, blurred vision, tachycardia, nausea, vomiting, diaphoresis, flushing, headache, dry mouth, and other adverse reactions similar to those seen in normal clinical experience. [See Adverse Reactions (6)]  Symptoms were transient, and no serious clinical outcome has been reported when omeprazole was taken alone. No specific antidote for omeprazole overdosage is known. Omeprazole is extensively protein bound and is, therefore, not readily dialyzable. In the event of overdosage, treatment should be symptomatic and supportive.


    As with the management of any overdose, the possibility of multiple drug ingestion should be considered. For current information on treatment of any drug overdose, a certified Regional Poison Control Center should be contacted. Telephone numbers are listed in the Physicians’ Desk Reference (PDR) or local telephone book.


    Single oral doses of omeprazole at 1350, 1339, and 1200 mg/kg were lethal to mice, rats, and dogs, respectively. Animals given these doses showed sedation, ptosis, tremors, convulsions, and decreased activity, body temperature, and respiratory rate and increased depth of respiration.


    In addition, a sodium bicarbonate overdose may cause hypocalcemia, hypokalemia, hypernatremia, and seizures.

  • 11 DESCRIPTION


    Omeprazole and sodium bicarbonate capsules is a combination of omeprazole, a proton-pump inhibitor, and sodium bicarbonate, an antacid. Omeprazole is a substituted benzimidazole, 5-methoxy-2-[[(4-methoxy-3,5-dimethyl-2-pyridinyl)methyl]sulfinyl]-1H-benzimidazole, a racemic mixture of two enantiomers that inhibits gastric acid secretion. Its structural formula is C17H19N3O3S, with a molecular weight of 345.42. The structural formula is:


    omeprazole-str


    Omeprazole is a white to off-white crystalline powder which melts with decomposition at about 155°C. It is a weak base, freely soluble in ethanol and methanol, and slightly soluble in acetone and isopropanol and very slightly soluble in water. The stability of omeprazole is a function of pH; it is rapidly degraded in acid media, but has acceptable stability under alkaline conditions.

    Omeprazole and sodium bicarbonate is supplied as immediate-release capsules. Each capsule contains either 40 mg or 20 mg of omeprazole and 1100 mg of sodium bicarbonate with the following excipients: croscarmellose sodium and magnesium stearate. The capsule shell contains gelatin, titanium dioxide, sodium lauryl sulfate, NF and the colorants FD&C Blue #1 (40 mg and 20 mg), FD&C Red# 3 (20 mg) and the components of ink, Edible ink type TekPrintTM SW-9008 Black Ink (Shellac, NF; Dehydrated Alcohol, USP; Isopropyl Alcohol, USP; Butyl Alcohol, NF; Propylene Glycol, USP; Strong Ammonia Solution, NF; Black Iron Oxide, NF, E172; Potassium Hydroxide, NF) or Opacode® Monogramming ink S-1-17823 Black (Shellac, NF; Isopropyl Alcohol, USP; Iron Oxide Black, NF; N-Butyl Alcohol, NF; Propylene Glycol, USP; Ammonium Hydroxide, NF). 

  • 12 CLINICAL PHARMACOLOGY

    12.1 Mechanism of Action



    Omeprazole belongs to a class of antisecretory compounds, the substituted benzimidazoles, that do not exhibit anticholinergic or H2 histamine antagonistic properties, but that suppress gastric acid secretion by specific inhibition of the H+/K+ ATPase enzyme system at the secretory surface of the gastric parietal cell. Because this enzyme system is regarded as the acid (proton) pump within the gastric mucosa, omeprazole has been characterized as a gastric acid-pump inhibitor, in that it blocks the final step of acid production. This effect is dose related and leads to inhibition of both basal and stimulated acid secretion irrespective of the stimulus. Animal studies indicate that after rapid disappearance from plasma, omeprazole can be found within the gastric muscosa for a day or more.


    Omeprazole is acid labile and thus rapidly degraded by gastric acid. Omeprazole and sodium bicarbonate capsules is an immediate-release formulation that contains sodium bicarbonate which raises the gastric pH and thus protects omeprazole from acid degradation.

    12.2 Pharmacodynamics


    Enterochromaffin-like (ECL) Cell Effects

    In 24-month carcinogenicity studies in rats, a dose-related significant increase in gastric carcinoid tumors and ECL cell hyperplasia was observed in both male and female animals. [See Nonclinical Toxicology(13.1)]Carcinoid tumors have also been observed in rats subjected to fundectomy or long-term treatment with other proton pump inhibitors or high doses of H2-receptor antagonists. Human gastric biopsy specimens have been obtained from more than 3000 patients treated with omeprazole in long-term clinical trials. The incidence of ECL cell hyperplasia in these studies increased with time; however, no case of ECL cell carcinoids, dysplasia, or neoplasia has been found in these patients. These studies are of insufficient duration and size to rule out the possible influence of long-term administration of omeprazole on the development of any premalignant or malignant conditions.


    Serum Gastrin Effects

    In studies involving more than 200 patients, serum gastrin levels increased during the first 1 to 2 weeks of once-daily administration of therapeutic doses of omeprazole in parallel with inhibition of acid secretion. No further increase in serum gastrin occurred with continued treatment. In comparison with histamine H2-receptor antagonists, the median increases produced by 20 mg doses of omeprazole were higher (1.3 to 3.6 fold vs. 1.1 to 1.8 fold increase). Gastrin values returned to pretreatment levels, usually within 1 to 2 weeks after discontinuation of therapy.

     
    Increased gastrin causes enterochromaffin-like cell hyperplasia and increased serum Chromogranin A (CgA) levels. The increased CgA levels may cause false positive results in diagnostic investigations for neuroendocrine tumors.


    Other Effects

    Systemic effects of omeprazole in the CNS, cardiovascular and respiratory systems have not been found to date. Omeprazole, given in oral doses of 30 or 40 mg for 2 to 4 weeks, had no effect on thyroid function, carbohydrate metabolism, or circulating levels of parathyroid hormone, cortisol, estradiol, testosterone, prolactin, cholecystokinin or secretin.

    No effect on gastric emptying of the solid and liquid components of a test meal was demonstrated after a single dose of omeprazole 90 mg. In healthy subjects, a single I.V. dose of omeprazole (0.35 mg/kg) had no effect on intrinsic factor secretion. No systematic dose-dependent effect has been observed on basal or stimulated pepsin output in humans. However, when intragastric pH is maintained at 4.0 or above, basal pepsin output is low, and pepsin activity is decreased.


    As do other agents that elevate intragastric pH, omeprazole administered for 14 days in healthy subjects produced a significant increase in the intragastric concentrations of viable bacteria. The pattern of the bacterial species was unchanged from that commonly found in saliva. All changes resolved within three days of stopping treatment.


    The course of Barrett’s esophagus in 106 patients was evaluated in a U.S. double-blind controlled study of omeprazole 40 mg b.i.d. for 12 months followed by 20 mg b.i.d. for 12 months or ranitidine 300 mg b.i.d. for 24 months. No clinically significant impact on Barrett’s mucosa by antisecretory therapy was observed. Although neosquamous epithelium developed during antisecretory therapy, complete elimination of Barrett’s mucosa was not achieved. No significant difference was observed between treatment groups in development of dysplasia in Barrett’s mucosa and no patient developed esophageal carcinoma during treatment. No significant differences between treatment groups were observed in development of ECL cell hyperplasia, corpus atrophic gastritis, corpus intestinal metaplasia, or colon polyps exceeding 3 mm in diameter.

    12.3 Pharmacokinetics

    Absorption

    In separate in vivo bioavailability studies, when omeprazole and sodium bicarbonate oral suspension and capsules are administered on an empty stomach 1 hour prior to a meal, the absorption of omeprazole is rapid, with mean peak plasma levels (% CV) of omeprazole being 1954 ng/mL (33%) and 1526 ng/mL (49%), respectively, and time to peak of approximately 30 minutes (range 10 to 90 min) after a single-dose or repeated-dose administration.

    Following single or repeated once daily dosing, peak plasma concentrations of omeprazole from omeprazole and sodium bicarbonate are approximately proportional from 20 to 40 mg doses, but a greater than linear mean AUC (three-fold increase) is observed when doubling the dose to 40 mg. The bioavailability of omeprazole from omeprazole and sodium bicarbonate increases upon repeated administration.

    When omeprazole and sodium bicarbonate is administered 1 hour after a meal, the omeprazole AUC is reduced by approximately 24% relative to administration 1 hour prior to a meal.

    Distribution

    Omeprazole is bound to plasma proteins. Protein binding is approximately 95%.

    Metabolism

    Following single-dose oral administration of omeprazole, the majority of the dose (about 77%) is eliminated in urine as at least six metabolites. Two metabolites have been identified as hydroxyomeprazole and the corresponding carboxylic acid. The remainder of the dose was recoverable in feces. This implies a significant biliary excretion of the metabolites of omeprazole.

    Three metabolites have been identified in plasma – the sulfide and sulfone derivatives of omeprazole, and hydroxyomeprazole. These metabolites have very little or no antisecretory activity.

    Excretion

    Following single-dose oral administration of omeprazole, little if any, unchanged drug is excreted in urine. The mean plasma omeprazole half-life in healthy subjects is approximately 1 hour (range 0.4 to 3.2 hours) and the total body clearance is 500 to 600 mL/min.

    Special Populations

    Geriatric

    The elimination rate of omeprazole was somewhat decreased in the elderly, and bioavailability was increased. Omeprazole was 76% bioavailable when a single 40 mg oral dose of omeprazole (buffered solution) was administered to healthy elderly subjects, versus 58% in young subjects given the same dose. Nearly 70% of the dose was recovered in urine as metabolites of omeprazole and no unchanged drug was detected. The plasma clearance of omeprazole was 250 mL/min (about half that of young subjects) and its plasma half-life averaged one hour, similar to that of young healthy subjects.

    Pediatric

    The pharmacokinetics of omeprazole and sodium bicarbonate has not been studied in patients < 18 years of age.

    Gender

    There are no known differences in the absorption or excretion of omeprazole between males and females.

    Hepatic Insufficiency

    In patients with chronic hepatic disease, the bioavailability of omeprazole from a buffered solution increased to approximately 100% compared to an I.V. dose, reflecting decreased first pass effect, and the mean plasma half-life of the drug increased to nearly 3 hours compared to the mean half-life of 1 hour in normal subjects. Plasma clearance averaged 70 mL/min, compared to a value of 500 to 600 mL/min in normal subjects. Dose reduction, particularly where maintenance of healing of erosive esophagitis is indicated, for the hepatically impaired should be considered.

    Renal Insufficiency

    In patients with chronic renal impairment, whose creatinine clearance ranged between 10 and 62 mL/min/1.73 m2, the disposition of omeprazole from a buffered solution was very similar to that in healthy subjects, although there was a slight increase in bioavailability. Because urinary excretion is a primary route of excretion of omeprazole metabolites, their elimination slowed in proportion to the decreased creatinine clearance. No dose reduction is necessary in patients with renal impairment.

    Asian Population

    In pharmacokinetic studies of single 20 mg omeprazole doses, an increase in AUC of approximately four-fold was noted in Asian subjects compared to Caucasians. Dose adjustment, particularly where maintenance of healing of erosive esophagitis is indicated, for Asian subjects should be considered.

  • 13 NONCLINICAL TOXICOLOGY

    13.1 Carcinogenesis, Mutagenesis, Impairment of Fertility


    In two 24-month carcinogenicity studies in rats, omeprazole at daily doses of 1.7, 3.4, 13.8, 44.0 and 140.8 mg/kg/day (approximately 0.4 to 34.2 times the human dose of 40 mg/day on a body surface area basis) produced gastric ECL cell carcinoids in a dose-related manner in both male and female rats; the incidence of this effect was markedly higher in female rats, which had higher blood levels of omeprazole. Gastric carcinoids seldom occur in the untreated rat. In addition, ECL cell hyperplasia was present in all treated groups of both sexes. In one of these studies, female rats were treated with 13.8 mg omeprazole/kg/day (approximately 3.36 times the human dose of 40 mg/day on a body surface area basis) for one year, then followed for an additional year without the drug. No carcinoids were seen in these rats. An increased incidence of treatment-related ECL cell hyperplasia was observed at the end of one year (94% treated versus 10% controls). By the second year the difference between treated and control rats was much smaller (46% versus 26%) but still showed more hyperplasia in the treated group. Gastric adenocarcinoma was seen in one rat (2%). No similar tumor was seen in male or female rats treated for two years. For this strain of rat no similar tumor has been noted historically, but a finding involving only one tumor is difficult to interpret. In a 52-week toxicity study in Sprague-Dawley rats, brain astrocytomas were found in a small number of males that received omeprazole at dose levels of 0.4, 2, and 16 mg/kg/day (about 0.1 to 3.9 times the human dose of 40 mg/day on a body surface area basis). No astrocytomas were observed in female rats in this study. In a 2-year carcinogenicity study in Sprague-Dawley rats, no astrocytomas were found in males and females at the high dose of 140.8 mg/kg/day (about 34 times the human dose of 40 mg/day on a body surface area basis). A 78-week mouse carcinogenicity study of omeprazole did not show increased tumor occurrence, but the study was not conclusive. A 26-week p53 (+/-) transgenic mouse carcinogenicity study was not positive.


    Omeprazole was positive for clastogenic effects in an in vitro human lymphocyte chromosomal aberration assay, in one of two in vivo mouse micronucleus tests, and in an in vivo bone marrow cell chromosomal aberration assay. Omeprazole was negative in the in vitro Ames Test, an in vitro mouse lymphoma cell forward mutation assay and an in vivo rat liver DNA damage assay.


    In 24-month carcinogenicity studies in rats, a dose-related significant increase in gastric carcinoid tumors and ECL cell hyperplasia was observed in both male and female animals [See Warnings and Precautions (5)]. Carcinoid tumors have also been observed in rats subjected to fundectomy or long-term treatment with other proton pump inhibitors or high doses of H2-receptor antagonists.


    Omeprazole at oral doses up to 138 mg/kg/day (about 33.6 times the human dose of 40 mg/day on a body surface area basis) was found to have no effect on the fertility and general reproductive performance in rats.

    13.2 Animal Toxicology and/or Pharmacology



    Reproductive Toxicology Studies

    Reproduction studies conducted in pregnant rats with omeprazole at doses up to 138 mg/kg/day (about 33.6times an oral human dose of 40 mg on a body surface area basis) and in pregnant rabbits at doses up to 69 mg/kg/day (about 33.6times an oral human dose of 40 mg on a body surface area basis) did not disclose any evidence for a teratogenic potential of omeprazole. In rabbits, omeprazole in a dose range of 6.9 to 69 mg/kg/day (about 3.3 to 33.6 times the human dose of 40 mg/day on a body surface area basis) produced dose-related increases in embryo-lethality, fetal resorptions and pregnancy disruptions. In rats, dose-related embryo/fetal toxicity and postnatal developmental toxicity were observed in offspring resulting from parents treated with omeprazole at 13.8 to 138.0 mg/kg/day (about 3.3 to 33.6 times the human dose of 40 mg/day on a body surface area basis).


    Juvenile Animal Study

    A 28-day toxicity study with a 14-day recovery phase was conducted in juvenile rats with esomeprazole magnesium at doses of 70 to 280 mg /kg/day (about 17 to 68 times a daily oral human dose of 40 mg on a body surface area basis). An increase in the number of deaths at the high dose of 280 mg /kg/day was observed when juvenile rats were administered esomeprazole magnesium from postnatal day 7 through postnatal day 35. In addition, doses equal to or greater than 140 mg/kg/day (about 34 times a daily oral human dose of 40 mg on a body surface area basis), produced treatment-related decreases in body weight (approximately 14%) and body weight gain, decreases in femur weight and femur length, and affected overall growth. Comparable findings described above have also been observed in this study with another esomeprazole salt, esomeprazole strontium, at equimolar doses of esomeprazole.

    Active Duodenal Ulcer - In a multicenter, double-blind, placebo controlled study of 147 patients with endoscopically documented duodenal ulcer, the percentage of patients healed (per protocol) at 2 and 4 weeks was significantly higher with omeprazole 20 mg once a day than with placebo (p < 0.01).

    In this study, the 40-mg dose was not superior to the 20-mg dose of omeprazole in the percentage healing rate. Other controlled clinical trials have also shown that omeprazole is effective in severe GERD. In comparisons with histamine H2-receptor antagonists in patients with erosive esophagitis, grade 2 or above, omeprazole in a dose of 20 mg was significantly more effective than the active controls. Complete daytime and nighttime heartburn relief occured significantly faster (p< 0.01) in patients treated with omeprazole than in those taking placebo or histamine H2-receptor antagonists.


    In this and five other controlled GERD studies, significantly more patients taking 20 mg omeprazole (84%) reported complete relief of GERD symptoms than patients receiving placebo (12%).

    14.4 Long Term Maintenance Treatment of Erosive Esophagitis


    In a U.S. double-blind, randomized, multicenter, placebo controlled study; two dose regimens of omeprazole were studied in patients with endoscopically confirmed healed esophagitis. Results to determine maintenance of healing of erosive esophagitis are shown in Table 11.

    In an international multicenter double-blind study, omeprazole 20 mg daily and 10 mg daily were compared to ranitidine 150 mg twice daily in patients with endoscopically confirmed healed esophagitis. Table 12 provides the results of this study for maintenance of healing of erosive esophagitis.

    In patients who initially had grades 3 or 4 erosive esophagitis, for maintenance after healing 20 mg daily of omeprazole was effective, while 10 mg did not demonstrate effectiveness.

  • 17 PATIENT COUNSELING INFORMATION



    See FDA-Approved Medication Guide.

    Instruct patients that omeprazole and sodium bicarbonate capsules should be taken on an empty stomach at least one hour prior to a meal. [See Dosage and Administration (2)]


    Instruct patients in Directions for Use as follows:


    Capsules: Swallow intact capsule with water. DO NOT USE OTHER LIQUIDS. DO NOT OPEN CAPSULE AND SPRINKLE CONTENTS INTO FOOD.


    Omeprazole and sodium bicarbonate is available either as 40 mg or 20 mg capsules with 1100 mg sodium bicarbonate.


    Patients should be instructed not to substitute omeprazole and sodium bicarbonate capsules for other omeprazole and sodium bicarbonate dosage forms because different dosage forms contain different amounts of sodium bicarbonate. [See Dosage and Administration (2)]


    Patients should be advised that since both the 20 mg and 40 mg capsules contain the same amount of sodium bicarbonate (1100 mg), two capsules of 20 mg are notequivalent to one capsule of omeprazole and sodium bicarbonate 40 mg; therefore, two 20 mg capsules of omeprazole and sodium bicarbonate should not be substituted for one capsule of omeprazole and sodium bicarbonate 40 mg. [See Dosage and Administration(2)]


    Patients should be advised that this drug is not approved for use in patients less than 18 years of age. [See Pediatric Use (8.4)]


    Patients on a sodium-restricted diet or patients at risk of developing congestive heart failure (CHF) should be informed of the sodium content of omeprazole and sodium bicarbonate capsules (304 mg per capsule). Patients should be informed that chronic use of sodium bicarbonate may cause problems and increased sodium intake can cause swelling and weight gain. If this occurs, they should contact their healthcare provider. [See Warnings and Precautions (5.5)]


    Patients should be informed that the most frequent adverse reactions associated with omeprazole and sodium bicarbonate capsules include headache, abdominal pain, nausea, diarrhea, vomiting and flatulence. [See Adverse Reactions (6)]


    Pregnant women should be advised that a harmful effect of omeprazole and sodium bicarbonate on the fetus can not be ruled out and that the drug should be used with caution during pregnancy. [See Pregnancy (8.1)]


    Patients should be advised to use this drug with caution if they are regularly taking calcium supplements. [See Warnings and Precautions (5.3)]


    Advise patients to immediately report and seek care for any cardiovascular or neurological symptoms including palpitations, dizziness, seizures and tetany as these may be signs of hypomagnesemia. [See Warnings and Precautions (5.6)]

  • 18 MEDICATION GUIDE

    Omeprazole and Sodium Bicarbonate Capsules

    (oh mep' ra zole and soe' dee um bye kar' bo nate)

     


    Read this Medication Guide before you start taking omeprazole and sodium bicarbonate capsules and each time you get a refill.  There may be new information.  This information 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 omeprazole and sodium bicarbonate capsules?


    Omeprazole and sodium bicarbonate capsules may help with your acid-related symptoms, but you could still have serious stomach problems.  Talk with your doctor.

    Omeprazole and sodium bicarbonate capsules can cause serious side effects, including:

         Omeprazole and sodium bicarbonate capsules contains sodium bicarbonate.  Tell your doctor if you are on a sodium restricted diet or if you have Bartter's Syndrome (a rare kidney disorder).


    Tell your doctor right away if you have confusion, shaking hands, dizziness, muscle twitching, nausea, vomiting, and numbness or tingling in the face, arms, or legs.


         Diarrhea. Omeprazole and sodium bicarbonate capsules 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 medicines for a long period of time (a year or longer) may have an increased risk of fractures of the hip, wrist or spine.  You should take omeprazole and sodium bicarbonate capsules 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 omeprazole and sodium bicarbonate capsules.


    Omeprazole and sodium bicarbonate capsules can have other serious side effects.  See “What are the possible side effects of omeprazole and sodium bicarbonate capsules?"

     

    What is omeprazole and sodium bicarbonate capsule?


    Omeprazole and sodium bicarbonate capsules are a medicine called a proton pump inhibitor (PPI). Omeprazole and sodium bicarbonate capsules reduce the amount of acid in your stomach.


    Omeprazole and sodium bicarbonate capsules are used in adults for:


    • for 4 weeks to heal ulcers in the first part of the small bowel (duodenal ulcers). Your doctor may prescribe an additional 4 weeks of omeprazole and sodium bicarbonate capsules.
    • for up to 8 weeks for healing stomach ulcers
    • for up to 4 weeks to treat heartburn and other symptoms that happen with gastroesophageal reflux disease (GERD).

    GERD happens when acid from the 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 8 weeks to heal acid-related damage to the lining of the esophagus (called erosive esophagitis or EE)
    • to maintain healing of the esophagus. Omeprazole and sodium bicarbonate capsules have not been studied for treatment lasting longer than 12 months (1 year)

    It is not known if omeprazole and sodium bicarbonate capsules are safe and effective in children and adolescents less than 18 years of age.

    Who should not take omeprazole and sodium bicarbonate capsules?


    Do not take omeprazole and sodium bicarbonate capsules if you:


    • are allergic to any of the ingredients in omeprazole and sodium bicarbonate capsules. See the end of this leaflet for a complete list of ingredients in omeprazole and sodium bicarbonate capsules.
    • are allergic to any other PPI medicine.

    • have any allergies
    • have any other medical conditions
    • are pregnant or plan to become pregnant.  It is not known if omeprazole and sodium bicarbonate capsules can harm your unborn baby.
    • are breastfeeding or plan to breastfeed. Omeprazole and sodium bicarbonate capsules can pass into your breast milk and may harm your baby. You and your doctor should decide if you will take omeprazole and sodium bicarbonate capsules or breastfeed.  You should not do both.  Talk with your doctor about the best way to feed your baby if you take omeprazole and sodium bicarbonate capsules.

    Tell your doctor about all the medicines you take, including prescription and non-prescription medicines, vitamins and herbal supplements. Omeprazole and sodium bicarbonate capsules may affect how other medicines work, and other medicines may affect how omeprazole and sodium bicarbonate capsules works.
