Drug Details [pdf]

  • 1 INDICATIONS AND USAGE

    Therapy with lipid-altering agents should be only one component of multiple risk factor intervention in individuals at significantly increased risk for atherosclerotic vascular disease due to hyperlipidemia. Niacin therapy is indicated as an adjunct to diet when the response to a diet restricted in saturated fat and cholesterol and other nonpharmacologic measures alone has been inadequate.


    1. Niacin extended-release tablets, USP are indicated to reduce elevated TC, LDL-C, Apo B and TG levels, and to increase HDL-C in patients with primary hyperlipidemia and mixed dyslipidemia.
    2. In patients with a history of myocardial infarction and hyperlipidemia, niacin is indicated to reduce the risk of recurrent nonfatal myocardial infarction.
    3. In patients with a history of coronary artery disease (CAD) and hyperlipidemia, niacin, in combination with a bile acid binding resin, is indicated to slow progression or promote regression of atherosclerotic disease.
    4. Niacin extended-release in combination with a bile acid binding resin is indicated to reduce elevated TC and LDL-C levels in adult patients with primary hyperlipidemia.
    5. Niacin is also indicated as adjunctive therapy for treatment of adult patients with severe hypertriglyceridemia who present a risk of pancreatitis and who do not respond adequately to a determined dietary effort to control them.

    Limitations of Use

    Addition of niacin extended-release did not reduce cardiovascular morbidity or mortality among patients treated with simvastatin in a large, randomized controlled trial (AIM-HIGH) [see Warnings and Precautions (5.1)].

  • 2 DOSAGE AND ADMINISTRATION

    Niacin extended-release tablets, USP should be taken at bedtime, after a low-fat snack, and doses should be individualized according to patient response. Therapy with niacin extended-release tablets, USP must be initiated at 500 mg at bedtime in order to reduce the incidence and severity of side effects which may occur during early therapy. The recommended dose escalation is shown in Table 1 below.

    *

    2,000 mg

    2 niacin extended-release 1,000 mg tablets or 4 niacin extended-release 500 mg tablets at bedtime

    * After Week 8, titrate to patient response and tolerance. If response to 1,000 mg daily is inadequate, increase dose to 1,500 mg daily; may subsequently increase dose to 2,000 mg daily. Daily dose should not be increased more than 500 mg in a 4-week period, and doses above 2,000 mg daily are not recommended. Women may respond at lower doses than men.


    Maintenance Dose
    The daily dosage of niacin extended-release tablets, USP should not be increased by more than 500 mg in any 4–week period. The recommended maintenance dose is 1,000 mg (two 500 mg tablets or one 1,000 mg tablet) to 2,000 mg (two 1,000 mg tablets or four 500 mg tablets) once daily at bedtime. Doses greater than 2,000 mg daily are not recommended. Women may respond at lower niacin extended-release tablets, USP doses than men [see Clinical Studies (14.2)].

    Single-dose bioavailability studies have demonstrated that two of the 500 mg and one of the 1,000 mg tablet strengths are interchangeable but three of the 500 mg and two of the 750 mg tablet strengths are not interchangeable.
     
    Flushing of the skin [see Adverse Reactions (6.1)] may be reduced in frequency or severity by pretreatment with aspirin (up to the recommended dose of 325 mg taken 30 minutes prior to niacin extended-release tablets, USP dose). Tolerance to this flushing develops rapidly over the course of several weeks. Flushing, pruritus, and gastrointestinal distress are also greatly reduced by slowly increasing the dose of niacin and avoiding administration on an empty stomach. Concomitant alcoholic, hot drinks or spicy foods may increase the side effects of flushing and pruritus and should be avoided around the time of niacin extended-release tablets, USP ingestion.
     
    Equivalent doses of niacin extended-release tablets, USP should not be substituted for sustained-release (modified-release, timed-release) niacin preparations or immediate-release (crystalline) niacin [see Warnings and Precautions (5)]. Patients previously receiving other niacin products should be started with the recommended niacin extended-release tablets, USP titration schedule (see Table 1), and the dose should subsequently be individualized based on patient response.
     
    If niacin extended-release tablets, USP therapy is discontinued for an extended period, reinstitution of therapy should include a titration phase (see Table 1).

    Niacin extended-release tablets, USP should be taken whole and should not be broken, crushed or chewed before swallowing.

    Dosage in Patients with Renal or Hepatic Impairment
    Use of niacin extended-release tablets, USP in patients with renal or hepatic impairment has not been studied. Niacin extended-release tablets, USP are contraindicated in patients with significant or unexplained hepatic dysfunction. Niacin extended-release tablets, USP should be used with caution in patients with renal impairment [see Warnings and Precautions (5)].

  • 3 DOSAGE FORMS AND STRENGTHS


    • 500 mg unscored, pink, film-coated, capsule-shaped tablets
    • 750 mg unscored, pink, film-coated, capsule-shaped tablets
    • 1,000 mg unscored, pink, film-coated, capsule-shaped tablets


  • 4 CONTRAINDICATIONS


    Niacin extended-release tablets are contraindicated in the following conditions: 


    • Active liver disease or unexplained persistent elevations in hepatic transaminases [see Warnings and Precautions (5.3)] 
    • Patients with active peptic ulcer disease 
    • Patients with arterial bleeding 
    • Hypersensitivity to niacin or any component of this medication [see Adverse Reactions (6.1)] 


  • 5 WARNINGS AND PRECAUTIONS

    Niacin extended-release tablets preparations should not be substituted for equivalent doses of immediate-release (crystalline) niacin. For patients switching from immediate-release niacin to niacin extended-release tablets, therapy with niacin extended-release tablets should be initiated with low doses (i.e., 500 mg at bedtime) and the niacin extended-release tablets dose should then be titrated to the desired therapeutic response [see Dosage and Administration (2)].


    Caution should also be used when niacin extended-release is used in patients with unstable angina or in the acute phase of an MI, particularly when such patients are also receiving vasoactive drugs such as nitrates, calcium channel blockers, or adrenergic blocking agents.


    Niacin is rapidly metabolized by the liver, and excreted through the kidneys. Niacin extended-release is contraindicated in patients with significant or unexplained hepatic impairment [see Contraindications (4) and Warnings and Precautions (5.3)] and should be used with caution in patients with renal impairment. Patients with a past history of jaundice, hepatobiliary disease, or peptic ulcer should be observed closely during niacin extended-release therapy.


    5.1 Mortality and Coronary Heart Disease Morbidity

    Niacin extended-release tablets

    have not been shown to reduce cardiovascular morbidity or mortality among patients already treated with a statin.

    The Atherothrombosis Intervention in Metabolic Syndrome with Low HDL/High Triglycerides: Impact on Global Health Outcomes (AIM-HIGH) trial was a randomized placebo-controlled trial of 3,414 patients with stable, previously diagnosed cardiovascular disease. Mean baseline lipid levels were LDL-C 74 mg/dL, HDL-C 35 mg/dL, non-HDL-C 111 mg/dL and median triglyceride level of 163 to 177 mg/dL. Ninety-four percent of patients were on background statin therapy prior to entering the trial. All participants received simvastatin, 40 to 80 mg per day, plus ezetimibe 10 mg per day if needed, to maintain an LDL-C level of 40 to 80 mg/dL, and were randomized to receive niacin extended-release 1,500 to 2,000 mg/day (n=1,718) or matching placebo (IR Niacin, 100 to 150 mg, n=1,696). On-treatment lipid changes at two years for LDL-C were -12% for the simvastatin plus niacin extended-release group and -5.5% for the simvastatin plus placebo group. HDL-C increased by 25% to 42 mg/dL in the simvastatin plus niacin extended-release group and by 9.8% to 38 mg/dL in the simvastatin plus placebo group (P<0.001). Triglyceride levels decreased by 28.6% in the simvastatin plus niacin extended-release group and by 8.1% in the simvastatin plus placebo group. The primary outcome was an ITT composite of the first study occurrence of coronary heart disease death, nonfatal myocardial infarction, ischemic stroke, hospitalization for acute coronary syndrome or symptom-driven coronary or cerebral revascularization procedures. The trial was stopped after a mean follow-up period of 3 years owing to a lack of efficacy. The primary outcome occurred in 282 patients in the simvastatin plus niacin extended-release group (16.4%) and in 274 patients in the simvastatin plus placebo group (16.2%) (HR 1.02 [95% CI, 0.87 to 1.21], P=0.79. In an ITT analysis, there were 42 cases of first occurrence of ischemic stroke reported, 27 (1.6%) in the simvastatin plus niacin extended-release group and 15 (0.9%) in the simvastatin plus placebo group, a non-statistically significant result (HR 1.79, [95%CI = 0.95 to 3.36], p=0.071). The on-treatment ischemic stroke events were 19 for the simvastatin plus niacin extended-release group and 15 for the simvastatin plus placebo group [see Adverse Reactions (6.1)].

    5.2 Skeletal Muscle

    Cases of rhabdomyolysis have been associated with concomitant administration of lipid-altering doses (≥1 g/day) of niacin and statins. Elderly patients and patients with diabetes, renal failure, or uncontrolled hypothyroidism are particularly at risk. Monitor patients for any signs and symptoms of muscle pain, tenderness, or weakness, particularly during the initial months of therapy and during any periods of upward dosage titration. Periodic serum creatine phosphokinase (CPK) and potassium determinations should be considered in such situations, but there is no assurance that such monitoring will prevent the occurrence of severe myopathy.

    5.3 Liver Dysfunction

    Cases of severe hepatic toxicity, including fulminant hepatic necrosis, have occurred in patients who have substituted sustained-release (modified-release, timed-release) niacin products for immediate-release (crystalline) niacin at equivalent doses.

     

    Niacin extended-release should be used with caution in patients who consume substantial quantities of alcohol and/or have a past history of liver disease. Active liver diseases or unexplained transaminase elevations are contraindications to the use of niacin extended-release.


    Niacin preparations have been associated with abnormal liver tests. In three placebo-controlled clinical trials involving titration to final daily niacin extended-release doses ranging from 500 mg to 3,000 mg, 245 patients received niacin extended-release for a mean duration of 17 weeks. No patient with normal serum transaminase levels (AST, ALT) at baseline experienced elevations to more than 3 times the upper limit of normal (ULN) during treatment with niacin extended-release. In these studies, fewer than 1% (2/245) of niacin extended-release patients discontinued due to transaminase elevations greater than 2 times the ULN.


    Liver-related tests should be performed on all patients during therapy with niacin extended-release. Serum transaminase levels, including AST and ALT (SGOT and SGPT), should be monitored before treatment begins, every 6 to 12 weeks for the first year, and periodically thereafter (e.g., at approximately 6-month intervals). Special attention should be paid to patients who develop elevated serum transaminase levels, and in these patients, measurements should be repeated promptly and then performed more frequently. If the transaminase levels show evidence of progression, particularly if they rise to 3 times ULN and are persistent, or if they are associated with symptoms of nausea, fever, and/or malaise, the drug should be discontinued.

    5.4 Laboratory Abnormalities

    Increase in Blood Glucose: Niacin treatment can increase fasting blood glucose. Frequent monitoring of blood glucose should be performed to ascertain that the drug is producing no adverse effects.
    Diabetic patients may experience a dose-related increase in glucose intolerance. Diabetic or potentially diabetic patients should be observed closely during treatment with
    niacin extended-release, particularly during the first few months of use or dose adjustment; adjustment of diet and/or hypoglycemic therapy may be necessary.


    Reduction in platelet count: Niacin extended-release has been associated with small but statistically significant dose-related reductions in platelet count (mean of -11% with 2,000 mg). Caution should be observed when niacin extended-release is administered concomitantly with anticoagulants; platelet counts should be monitored closely in such patients.


    Increase in Prothrombin Time (PT): Niacin extended-release has been associated with small but statistically significant increases in prothrombin time (mean of approximately +4%); accordingly, patients undergoing surgery should be carefully evaluated. Caution should be observed when niacin extended-release is administered concomitantly with anticoagulants; prothrombin time should be monitored closely in such patients.


    Increase in Uric Acid: Elevated uric acid levels have occurred with niacin therapy, therefore use with caution in patients predisposed to gout.


    Decrease in Phosphorus: In placebo-controlled trials, niacin extended-release has been associated with small but statistically significant, dose-related reductions in phosphorus levels (mean of -13% with 2,000 mg). Although these reductions were transient, phosphorus levels should be monitored periodically in patients at risk for hypophosphatemia.

  • 6 ADVERSE REACTIONS

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

    6.1 Clinical Studies Experience


    In the placebo-controlled clinical trials database of 402 patients (age range 21 to 75 years, 33% women, 89% Caucasians, 7% Blacks, 3% Hispanics, 1% Asians) with a median treatment duration of 16 weeks, 16% of patients on niacin extended-release and 4% of patients on placebo discontinued due to adverse reactions. The most common adverse reactions in the group of patients treated with niacin extended-release that led to treatment discontinuation and occurred at a rate greater than placebo were flushing (6% vs. 0%), rash (2% vs. 0%), diarrhea (2% vs. 0%), nausea (1% vs. 0%), and vomiting (1% vs. 0%). The most commonly reported adverse reactions (incidence >5% and greater than placebo) in the niacin extended-release controlled clinical trial database of 402 patients were flushing, diarrhea, nausea, vomiting, increased cough and pruritus.


    In the placebo-controlled clinical trials, flushing episodes (i.e., warmth, redness, itching and/or tingling) were the most common treatment-emergent adverse reactions (reported by as many as 88% of patients) for niacin extended-release. Spontaneous reports suggest that flushing may also be accompanied by symptoms of dizziness, tachycardia, palpitations, shortness of breath, sweating, burning sensation/skin burning sensation, chills, and/or edema, which in rare cases may lead to syncope. In pivotal studies, 6% (14/245) of niacin extended-release patients discontinued due to flushing. In comparisons of immediate-release (IR) niacin and niacin extended-release tablets, although the proportion of patients who flushed was similar, fewer flushing episodes were reported by patients who received niacin extended-release tablets. Following 4 weeks of maintenance therapy at daily doses of 1,500 mg, the incidence of flushing over the 4-week period averaged 8.6 events per patient for IR niacin versus 1.9 following niacin extended-release tablets.


    Other adverse reactions occurring in ≥5% of patients treated with niacin extended-release tablets and at an incidence greater than placebo are shown in Table 2 below.

    Atherothrombosis Intervention in Metabolic Syndrome with Low HDL/High Triglycerides: Impact on Global Health Outcomes (AIM-HIGH)

    In AIM-HIGH involving 3,414 patients (mean age of 64 years, 15% women, 92% Caucasians, 34% with diabetes mellitus) with stable, previously diagnosed cardiovascular disease, all patients received simvastatin, 40 to 80 mg per day, plus ezetimibe 10 mg per day if needed, to maintain an LDL-C level of 40 to 80 mg/dL, and were randomized to receive niacin extended-release 1,500 to 2,000 mg/day (n=1,718) or matching placebo (IR Niacin, 100 mg to 150 mg, n=1,696). The incidence of the adverse reactions of “blood glucose increased” (6.4% vs. 4.5%) and “diabetes mellitus” (3.6% vs. 2.2%) was significantly higher in the simvastatin plus niacin extended-release group as compared to the simvastatin plus placebo group. There were 5 cases of rhabdomyolysis reported, 4 (0.2%) in the simvastatin plus niacin extended-release group and one (<0.1%) in the simvastatin plus placebo group [see Warnings and Precautions (5.1)].

    6.2 Postmarketing Experience

    Because the below reactions are reported voluntarily from a population of uncertain size, it is generally not possible to reliably estimate their frequency or establish a causal relationship to drug exposure.


    The following additional adverse reactions have been identified during post-approval use of niacin extended-release tablets:


    Hypersensitivity reactions, including anaphylaxis, angioedema, urticaria, flushing, dyspnea, tongue edema, larynx edema, face edema, peripheral edema, laryngismus, and vesiculobullous rash; maculopapular rash; dry skin; tachycardia; palpitations; atrial fibrillation; other cardiac arrhythmias; syncope; hypotension; postural hypotension; blurred vision; macular edema; peptic ulcers; eructation; flatulence; hepatitis; jaundice; decreased glucose tolerance; gout; myalgia; myopathy; dizziness; insomnia; asthenia; nervousness; paresthesia; dyspnea; sweating; burning sensation/skin burning sensation; skin discoloration, and migraine.


    Clinical Laboratory Abnormalities

    Chemistry: Elevations in serum transaminases [see Warnings and Precautions (5.3)], LDH, fasting glucose, uric acid, total bilirubin, amylase and creatine kinase, and reduction in phosphorus.


    Hematology: Slight reductions in platelet counts and prolongation in prothrombin time [see Warnings and Precautions (5.4)].

  • 7 DRUG INTERACTIONS

    7.1 Statins

    Caution should be used when prescribing niacin (≥1 gm/day) with statins as these drugs can increase risk of myopathy/rhabdomyolysis [see Warnings and Precautions (5) and Clinical Pharmacology (12.3)]

    7.2 Bile Acid Sequestrants

    An in vitro study results suggest that the bile acid-binding resins have high niacin binding capacity. Therefore, 4 to 6 hours, or as great an interval as possible, should elapse between the ingestion of bile acid-binding resins and the administration of niacin extended-release [see Clinical Pharmacology (12.3)]. 

    7.3 Aspirin

    Concomitant aspirin may decrease the metabolic clearance of nicotinic acid. The clinical relevance of this finding is unclear.

    7.4 Antihypertensive Therapy

    Niacin may potentiate the effects of ganglionic blocking agents and vasoactive drugs resulting in postural hypotension.

    7.5 Other

    Vitamins or other nutritional supplements containing large doses of niacin or related compounds such as nicotinamide may potentiate the adverse effects of niacin extended-release.

    7.6 Laboratory Test Interactions

    Niacin may produce false elevations in some fluorometric determinations of plasma or urinary catecholamines. Niacin may also give false-positive reactions with cupric sulfate solution (Benedict’s reagent) in urine glucose tests.

  • 8 USE IN SPECIFIC POPULATIONS

    8.1 Pregnancy

    Pregnancy Category C.

    Animal reproduction studies have not been conducted with niacin or with niacin extended-release tablets. It is also not known whether niacin at doses typically used for lipid disorders can cause fetal harm when administered to pregnant women or whether it can affect reproductive capacity. If a woman receiving niacin for primary hyperlipidemia becomes pregnant, the drug should be discontinued. If a woman being treated with niacin for hypertriglyceridemia conceives, the benefits and risks of continued therapy should be assessed on an individual basis.

    8.3 Nursing Mothers

    Niacin is excreted into human milk but the actual infant dose or infant dose as a percent of the maternal dose is not known. Because of the potential for serious adverse reactions in nursing infants from lipid-altering doses of nicotinic acid, a decision should be made whether to discontinue nursing or to discontinue the drug, taking into account the importance of the drug to the mother. No studies have been conducted with niacin extended-release tablets in nursing mothers.

    8.4 Pediatric Use

    Safety and effectiveness of niacin therapy in pediatric patients (≤16 years) have not been established. 

    8.5 Geriatric Use

    Of 979 patients in clinical studies of niacin extended-release, 21% of the patients were age 65 and over. No overall differences in safety and effectiveness were observed between these patients and younger patients, 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 Renal Impairment

    No studies have been performed in this population. Niacin extended-release should be used with caution in patients with renal impairment [see Warnings and Precautions (5)].

    8.7 Hepatic Impairment

    No studies have been performed in this population. Niacin extended-release should be used with caution in patients with a past history of liver disease and/or who consume substantial quantities of alcohol. Active liver disease, unexplained transaminase elevations and significant or unexplained hepatic dysfunction are contraindications to the use of niacin extended-release [see Contraindications (4) and Warnings and Precautions (5.3)]. 

    8.8 Gender

    Data from the clinical trials suggest that women have a greater hypolipidemic response than men at equivalent doses of niacin extended-release. 

  • 10 OVERDOSAGE

    Supportive measures should be undertaken in the event of an overdose.

  • 11 DESCRIPTION

    Niacin extended-release tablet, USP contains niacin, which at therapeutic doses is an antihyperlipidemic agent. Niacin (nicotinic acid, or 3-pyridinecarboxylic acid) is a white, crystalline powder, sparingly soluble in water, with the following structural formula:


    niacin-structure

    Niacin extended-release tablets, USP are unscored, pink, film-coated tablets for oral administration and are available in three tablet strengths containing 500 mg, 750 mg, and 1,000 mg niacin USP. Niacin extended-release tablets, USP also contain the inactive ingredients hypromellose, hydrogenated vegetable oil Type I, glyceryl behenate, colloidal silicon dioxide, magnesium stearate, polyvinyl alcohol-partially hydrolyzed, titanium dioxide, polyethylene glycol, talc, iron oxide red and iron oxide yellow.
    USP Dissolution Test Pending

  • 12 CLINICAL PHARMACOLOGY

    12.1 Mechanism of Action

    The mechanism by which niacin alters lipid profiles has not been well defined. It may involve several actions including partial inhibition of release of free fatty acids from adipose tissue, and increased lipoprotein lipase activity, which may increase the rate of chylomicron triglyceride removal from plasma. Niacin decreases the rate of hepatic synthesis of VLDL and LDL, and does not appear to affect fecal excretion of fats, sterols, or bile acids.

    12.3 Pharmacokinetics

    Absorption

    Due to extensive and saturable first-pass metabolism, niacin concentrations in the general circulation are dose dependent and highly variable. Time to reach the maximum niacin plasma concentrations was about 5 hours following niacin extended-release tablets. To reduce the risk of gastrointestinal (GI) upset, administration of niacin extended-release tablets with a low-fat meal or snack is recommended.


    Single-dose bioavailability studies have demonstrated that the 500 mg and 1,000 mg tablet strengths are dosage form equivalent but the 500 mg and 750 mg tablet strengths are not dosage form equivalent.


    Metabolism

    The pharmacokinetic profile of niacin is complicated due to extensive first-pass metabolism that is dose-rate specific and, at the doses used to treat dyslipidemia, saturable. In humans, one pathway is through a simple conjugation step with glycine to form nicotinuric acid (NUA). NUA is then excreted in the urine, although there may be a small amount of reversible metabolism back to niacin. The other pathway results in the formation of nicotinamide adenine dinucleotide (NAD). It is unclear whether nicotinamide is formed as a precursor to, or following the synthesis of, NAD. Nicotinamide is further metabolized to at least N-methylnicotinamide (MNA) and nicotinamide-N-oxide (NNO). MNA is further metabolized to two other compounds, N-methyl-2-pyridone-5-carboxamide (2PY) and N-methyl-4-pyridone-5-carboxamide (4PY). The formation of 2PY appears to predominate over 4PY in humans. At the doses used to treat hyperlipidemia, these metabolic pathways are saturable, which explains the nonlinear relationship between niacin dose and plasma concentrations following multiple-dose niacin extended-release tablets administration.


    Nicotinamide does not have hypolipidemic activity; the activity of the other metabolites is unknown.


    Elimination

    Following single and multiple doses, approximately 60 to 76% of the niacin dose administered as niacin extended-release tablets was recovered in urine as niacin and metabolites; up to 12% was recovered as unchanged niacin after multiple dosing. The ratio of metabolites recovered in the urine was dependent on the dose administered.


    Pediatric Use

    No pharmacokinetic studies have been performed in this population (≤16 years) [see Use in Specific Populations (8.4)].

     
    Geriatric Use

    No pharmacokinetic studies have been performed in this population (> 65 years) [see Use in Specific Populations (8.5)].


    Renal Impairment 

    No pharmacokinetic studies have been performed in this population. Niacin extended-release tablets should be used with caution in patients with renal disease [see Warnings and Precautions (5)].


    Hepatic Impairment

    No pharmacokinetic studies have been performed in this population. Active liver disease, unexplained transaminase elevations and significant or unexplained hepatic dysfunction are contraindications to the use of niacin extended-release tablets [see Contraindications (4) and Warnings and Precautions (5.3)].


    Gender
    Steady-state plasma concentrations of niacin and metabolites after administration of niacin extended-release tablets are generally higher in women than in men, with the magnitude of the difference varying with dose and metabolite. This gender differences observed in plasma levels of niacin and its metabolites may be due to gender-specific differences in metabolic rate or volume of distribution. Recovery of niacin and metabolites in urine, however, is generally similar for men and women, indicating that absorption is similar for both genders [see Gender (8.8)].

      

    Drug interactions 

    Fluvastatin
    Niacin did not affect fluvastatin pharmacokinetics [see Drug Interactions (7.1)].


    Lovastatin

    When niacin extended-release 2,000 mg and lovastatin 40 mg were co-administered, niacin extended-release increased lovastatin Cmax and AUC by 2% and 14%, respectively, and decreased lovastatin acid Cmax and AUC by 22% and 2%, respectively. Lovastatin reduced niacin extended-release bioavailability by 2 to 3% [see Drug Interactions (7.1)].


    Simvastatin
    When niacin extended-release 2,000 mg and simvastatin 40 mg were co-administered, niacin extended-release increased simvastatin Cmax and AUC by 1% and 9%, respectively, and simvastatin acid Cmax and AUC by 2% and 18%, respectively. Simvastatin reduced niacin extended-release bioavailability by 2% [see Drug Interactions (7.1)].


    Bile Acid Sequestrants

    An in vitro study was carried out investigating the niacin-binding capacity of colestipol and cholestyramine. About 98% of available niacin was bound to colestipol, with 10 to 30% binding to cholestyramine [see Drug Interactions (7.2)].

  • 13 NONCLINICAL TOXICOLOGY

    13.1 Carcinogenesis and Mutagenesis and Impairment of Fertility

    Niacin administered to mice for a lifetime as a 1% solution in drinking water was not carcinogenic. The mice in this study received approximately 6 to 8 times a human dose of 3,000 mg/day as determined on a mg/m2 basis. Niacin was negative for mutagenicity in the Ames test. No studies on impairment of fertility have been performed. No studies have been conducted with niacin extended-release regarding carcinogenesis, mutagenesis, or impairment of fertility.

  • 14 CLINICAL STUDIES

    14.1 Niacin Clinical Studies

    Niacin’s ability to reduce mortality and the risk of definite, nonfatal myocardial infarction (MI) has been assessed in long-term studies. The Coronary Drug Project, completed in 1975, was designed to assess the safety and efficacy of niacin and other lipid-altering drugs in men 30 to 64 years old with a history of MI. Over an observation period of 5 years, niacin treatment was associated with a statistically significant reduction in nonfatal, recurrent MI. The incidence of definite, nonfatal MI was 8.9% for the 1,119 patients randomized to nicotinic acid versus 12.2% for the 2,789 patients who received placebo (p<0.004). Total mortality was similar in the two groups at 5 years (24.4% with nicotinic acid versus 25.4% with placebo; p=N.S.). At the time of a 15-year follow-up, there were 11% (69) fewer deaths in the niacin group compared to the placebo cohort (52% versus 58.2%; p=0.0004).


    However, mortality at 15 years was not an original endpoint of the Coronary Drug Project. In addition, patients had not received niacin for approximately 9 years, and
    confounding variables such as concomitant medication use and medical or surgical treatments were not controlled.


    The Cholesterol-Lowering Atherosclerosis Study (CLAS) was a randomized, placebo-controlled, angiographic trial testing combined colestipol and niacin therapy in 162 non-smoking males with previous coronary bypass surgery.


    The primary, per-subject cardiac endpoint was global coronary artery change score. After 2 years, 61% of patients in the placebo cohort showed disease progression by global change score (n=82), compared with only 38.8% of drug-treated subjects (n=80), when both native arteries and grafts were considered (p<0.005); disease regression also occurred more frequently in the drug-treated group (16.2% versus 2.4%; p=0.002). In a follow-up to this trial in a subgroup of 103 patients treated for 4 years, again, significantly fewer patients in the drug-treated group demonstrated progression than in the placebo cohort (48% versus 85%, respectively; p<0.0001).


    The Familial Atherosclerosis Treatment Study (FATS) in 146 men ages 62 and younger with Apo B levels ≥125 mg/dL, established coronary artery disease, and family histories of vascular disease, assessed change in severity of disease in the proximal coronary arteries by quantitative arteriography. Patients were given dietary counseling and randomized to treatment with either conventional therapy with double placebo (or placebo plus colestipol if the LDL-C was elevated); lovastatin plus colestipol; or niacin plus colestipol. In the conventional therapy group, 46% of patients had disease progression (and no regression) in at least one of nine proximal coronary segments; regression was the only change in 11%. In contrast, progression (as the only change) was seen in only 25% in the niacin plus colestipol group, while regression was observed in 39%. Though not an original endpoint of the trial, clinical events (death, MI, or revascularization for worsening angina) occurred in 10 of 52 patients who received conventional therapy, compared with 2 of 48 who received niacin plus colestipol. 

    14.2 Niacin Extended-Release Tablets Clinical Studies


    Placebo-Controlled Clinical Studies in Patients with Primary Hyperlipidemia and Mixed Dyslipidemia: In two randomized, double-blind, parallel, multi-center, placebo-controlled trials, niacin extended-release tablets dosed at 1,000 mg, 1,500 mg or 2,000 mg daily at bedtime with a low-fat snack for 16 weeks (including 4 weeks of dose escalation) favorably altered lipid profiles compared to placebo (Table 3). Women appeared to have a greater response than men at each niacin extended-release tablets dose level (see Gender Effect, below).

    Other Patient Populations: In a double-blind, multi-center, 19-week study the lipid-altering effects of niacin extended-release tablets (forced titration to 2,000 mg at bedtime) were compared to baseline in patients whose primary lipid abnormality was a low level of HDL-C (HDL-C ≤40 mg/dL, TG ≤400 mg/dL, and LDL-C ≤160, or <130 mg/dL in the presence of CHD). Results are shown below (Table 7).

  • 17 PATIENT COUNSELING INFORMATION

    17.1 Patient Counseling

    Patients should be advised to adhere to their National Cholesterol Education Program (NCEP) recommended diet, a regular exercise program, and periodic testing of a fasting lipid panel.


    Patients should be advised to inform other healthcare professionals prescribing a new medication that they are taking niacin extended-release tablets.


    The patient should be informed of the following:


    Dosing Time

    Niacin extended-release tablets should be taken at bedtime, after a low-fat snack. Administration on an empty stomach is not recommended.

     
    Tablet Integrity

    Niacin extended-release tablets should not be broken, crushed or chewed, but should be swallowed whole.


    Dosing Interruption

    If dosing is interrupted for any length of time, their physician should be contacted prior to restarting therapy; re-titration is recommended.


    Muscle Pain

    Notify their physician of any unexplained muscle pain, tenderness, or weakness promptly. They should discuss all medication, both prescription and over the counter, with their physician.


    Flushing
    Flushing (warmth, redness, itching and/or tingling of the skin) is a common side effect of niacin therapy that may subside after several weeks of consistent niacin extended-release tablets use. Flushing may vary in severity and is more likely to occur with initiation of therapy, or during dose increases. By dosing at bedtime, flushing will most likely occur during sleep. However, if awakened by flushing at night, the patient should get up slowly, especially if feeling dizzy, feeling faint, or taking blood pressure medications. Advise patients of the symptoms of flushing and how they differ from the symptoms of a myocardial infarction.

     
    Use of Aspirin Medication

    Taking aspirin (up to the recommended dose of 325 mg) approximately 30 minutes before dosing can minimize flushing.

     
    Diet
    Avoid ingestion of alcohol, hot beverages and spicy foods around the time of taking niacin extended-release tablets to minimize flushing.

     
    Supplements

    Notify their physician if they are taking vitamins or other nutritional supplements containing niacin or nicotinamide.


    Dizziness
    Notify their physician if symptoms of dizziness occur.


    Diabetics

    If diabetic, to notify their physician of changes in blood glucose.

    Pregnancy
    Discuss future pregnancy plans with your patients, and discuss when to stop niacin extended-release tablets if they are trying to conceive. Patients should be advised that if they become pregnant, they should stop taking niacin extended-release tablets and call their healthcare professional.


    Breastfeeding
    Women who are breastfeeding should be advised to not use niacin extended-release tablets. Patients, who have a lipid disorder and are breastfeeding, should be advised to discuss the options with their healthcare professional.

  • PATIENT INFORMATION

    Niacin (nahy-uh-sin)

    Extended-release Tablets, USP

    Read this information carefully before you start taking niacin extended-release tablets and each time you get a refill. There may be new information. This information does not take the place of talking with your doctor about your medical condition or your treatment.

    What are niacin extended-release tablets?


    Niacin extended-release tablets are prescription medicines used with diet and exercise to increase the good cholesterol (HDL) and lower the bad cholesterol (LDL) and fats (triglycerides) in your blood.


    • Niacin extended-release tablets are also used to lower the risk of heart attack in people who have had a heart attack and have high cholesterol.
    • In people with coronary artery disease and high cholesterol, niacin extended-release tablets, when used with a bile acid-binding resin (another cholesterol medicine) can slow down or lessen the build-up of plaque (fatty deposits) in your arteries
    • In people with heart problems and well-controlled cholesterol, taking niacin extended-release tablets with another cholesterol-lowering medicine (simvastatin)does not reduce heart attacks or strokes more than taking simvastatin alone.

    It is not known if niacin extended-release tablets are safe and effective in children 16 years of age and under.

    Who should not take niacin extended-release tablets?

    Do not take niacin extended-release tablets if you have:

    • liver problems
    • a stomach ulcer
    • bleeding problems
    • an allergy to niacin or any of the ingredients in niacin extended-release tablets. See the end of this leaflet for a complete list of ingredients in niacin extended-release tablets.

    What should I tell my doctor before taking niacin extended-release tablets?

    Before you take niacin extended-release tablets, tell your doctor, if you:

    • have diabetes. Tell your doctor if your blood sugar levels change after you take niacin extended-release tablets.
    • have gout
    • have kidney problems
    • are pregnant or plan to become pregnant. It is not known if niacin extended-release tablets will harm your unborn baby. Talk to your doctor if you are pregnant or plan to become pregnant while taking niacin extended-release tablets.
    • are breastfeeding or plan to breastfeed. Niacin can pass into your breast milk. You and your doctor should decide if you will take niacin extended-release tablets or breastfeed. You should not do both. Talk to your doctor about the best way to feed your baby if you take niacin extended-release tablets.

    Tell your doctor about all the medicines you take, including prescription and non-prescription medicines, vitamins, herbal supplements or other nutritional supplements containing niacin or nicotinamide. Niacin extended-release tablets and other medicines may affect each other causing side effects. Niacin extended-release tablets may affect the way other medicines work, and other medicines may affect how niacin extended-release tablets work.

    Especially tell your doctor if you take:

    • other medicines to lower cholesterol or triglycerides
    • aspirin
    • blood pressure medicines
    • blood thinner medicines
    • large amounts of alcohol

    Know the medicines you take. Keep a list of them to show your doctor and pharmacist when you get a new medicine.

    How should I take niacin extended-release tablets?


    • Take niacin extended-release tablets exactly as your doctor tells you to take it.
    • Take niacin extended-release tablets whole. Do not break, crush or chew niacin extended-release tablets before swallowing.
    • Take niacin extended-release tablets 1 time a day at bedtime after a low-fat snack. Niacin extended-release tablets should not be taken on an empty stomach.
    • All forms of niacin are not the same as niacin extended-release tablets. Do not switch between forms of niacin without first talking to your doctor as severe liver damage can occur.
    • Do not change your dose or stop taking niacin extended-release tablets unless your doctor tells you to.
    • If you need to stop taking niacin extended-release tablets, call your doctor before you start taking niacin extended-release tablets again. Your doctor may need to lower your dose of niacin extended-release tablets.
    • If you forget to take a dose of niacin extended-release tablets, take it as soon as you remember.
    • If you take too many niacin extended-release tablets, call your doctor right away.
    • Medicines used to lower your cholesterol called bile acid resins, such as colestipol and cholestyramine, should not be taken at the same time of day as niacin extended-release tablets. You should take niacin extended-release tablets and the bile acid resin medicine at least 4 to 6 hours apart.
    • Your doctor may do blood tests before you start taking niacin extended-release tablets and during your treatment. You should see your doctor regularly to check your cholesterol and triglyceride levels and to check for side effects.

    What are the possible side effects of niacin extended-release tablets?

    Niacin extended-release tablets may cause serious side effects, including:

    • severe liver problems. Signs of liver problems include:
      • increased tiredness
      • dark colored urine (tea-colored)
      • loss of appetite
      • light colored stools
      • nausea
      • right upper stomach (abdomen) pain
      • yellowing of your skin or whites of your eye
      • itchy skin
    • unexplained muscle pain, tenderness or weakness
    • high blood sugar level (glucose)

    Call your doctor right away if you have any of the side effects listed above.


    The most common side effects of niacin extended-release tablets include:

    • flushing
    • diarrhea
    • nausea
    • vomiting
    • increased cough
    • rash

    Flushing is the most common side effect of niacin extended-release tablets. Flushing happens when tiny blood vessels near the surface of the skin (especially on the face, neck, chest and/or back) open wider. Symptoms of flushing may include any or all of the following:

    • warmth
    • redness
    • itching
    • tingling of the skin

    Flushing does not always happen. If it does, it is usually within 2 to 4 hours after taking a dose of niacin extended-release tablets. Flushing may last for a few hours. Flushing is more likely to happen when you first start taking niacin extended-release tablets or when your dose of niacin extended-release tablets is increased. Flushing may get better after several weeks.


    If you wake up at night because of flushing, get up slowly, especially if you:

    • feel dizzy or faint
    • take blood pressure medicines

    To lower your chance of flushing:


    • Ask your doctor if you can take aspirin to help lower the flushing side effect from niacin extended-release tablets. You can take aspirin (up to the recommended dose of 325 mg) about 30 minutes before you take niacin extended-release tablets to help lower the flushing side effect.
    • Do not drink hot beverages (including coffee), alcohol, or eat spicy foods around the time you take niacin extended-release tablets.
    • Take niacin extended-release tablets with a low-fat snack to lessen upset stomach.

    People with high cholesterol and heart disease are at risk for a heart attack. Symptoms of a heart attack may be different from a flushing reaction from niacin extended-release tablets. The following may be symptoms of a heart attack due to heart disease and not a flushing reaction:

    • chest pain
    • pain in other areas of your upper body such as one or both arms, back, neck, jaw or stomach
    • shortness of breath
    • sweating
    • nausea
    • lightheadedness

    The chest pain you have with a heart attack may feel like uncomfortable pressure, squeezing, fullness or pain that lasts more than a few minutes, or that goes away and comes back. Heart attacks may be sudden and intense, but often start slowly, with mild pain or discomfort.


    Call your doctor right away if you have any symptoms of a heart attack.


    Tell your doctor if you have any side effect that bothers you or does not go away.


    These are not all the possible side effects of niacin extended-release tablets. For more information, ask your doctor or pharmacist.


    Call your doctor for medical advice about side effects. You may report side effects to FDA at 1-800-FDA-1088.

    How should I store niacin extended-release tablets?

    • Store at 20° to 25°C (68° to 77°F); excursions permitted between 15° and 30°C (59° and 86°F).

    Keep niacin extended-release tablets and all medicines out of the reach of children.
