Side Effects & Adverse Reactions
ADVICOR should not be substituted for equivalent doses of immediate-release (crystalline) niacin. For patients switching from immediate-release niacin to NIASPAN, therapy with NIASPAN should be initiated with low doses (i.e., 500 mg once daily at bedtime) and the NIASPAN dose should then be titrated to the desired therapeutic response (see DOSAGE AND ADMINISTRATION).
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.
ADVICOR should be used with caution in patients who consume substantial quantities of alcohol and/or have a past history of liver disease. Active liver disease or unexplained transaminase elevations are contraindications to the use of ADVICOR.
Niacin preparations and lovastatin preparations have been associated with abnormal liver tests. In studies using NIASPAN alone, 0.8% of patients were discontinued for transaminase elevations. In studies using lovastatin alone, 0.2% of patients were discontinued for transaminase elevations.2 In three safety and efficacy studies involving titration to final daily ADVICOR doses ranging from 500 mg/10 mg to 2500 mg/40 mg, ten of 1028 patients (1.0%) experienced reversible elevations in AST/ALT to more than 3 times the upper limit of normal (ULN). Three of ten elevations occurred at doses outside the recommended dosing limit of 2000 mg/40 mg; no patient receiving 1000 mg/20 mg had 3-fold elevations in AST/ALT.
In clinical studies with ADVICOR, elevations in transaminases did not appear to be related to treatment duration; elevations in AST and ALT levels did appear to be dose related. Transaminase elevations were reversible upon discontinuation of ADVICOR.
It is recommended that liver enzyme tests be obtained prior to initiating therapy with ADVICOR and repeated as clinically indicated.
There have been rare postmarketing reports of fatal and non-fatal hepatic failure in patients taking statins, including lovastatin. If serious liver injury with clinical symptoms and/or hyperbilirubinemia or jaundice occurs during treatment with ADVICOR, promptly interrupt therapy. If an alternate etiology is not found do not restart ADVICOR.
Lovastatin and other inhibitors of HMG-CoA reductase occasionally cause myopathy, which is manifested as muscle pain or weakness associated with grossly elevated creatine kinase (> 10 times ULN). Rhabdomyolysis, with or without acute renal failure secondary to myoglobinuria, has been reported rarely and can occur at any time. In a large, long-term, clinical safety and efficacy study (the EXCEL study)3,4 with lovastatin, myopathy occurred in up to 0.2% of patients treated with lovastatin 20 to 80 mg for up to 2 years. When drug treatment was interrupted or discontinued in these patients, muscle symptoms and creatine kinase (CK) increases promptly resolved. The risk of myopathy is increased by concomitant therapy with certain drugs, some of which were excluded by the EXCEL study design.
The risk of myopathy/rhabdomyolysis is increased by concomitant use of lovastatin with the following:
Strong inhibitors of CYP3A4: The risk of myopathy appears to be increased by high levels of HMG-CoA reductase inhibitory activity in plasma. Lovastatin is metabolized by the cytochrome P450 isoform 3A4. Certain drugs which share this metabolic pathway can raise the plasma levels of lovastatin and may increase the risk of myopathy. These include itraconazole, ketoconazole, and posaconazole, the macrolide antibiotics erythromycin and clarithromycin, and the ketolide antibiotic telithromycin, HIV protease inhibitors, boceprevir, telaprevir, the antidepressant nefazodone, or large quantities of grapefruit juice (>1 quart daily). Combination of these drugs with lovastatin is contraindicated. If treatment with itraconazole, ketoconazole, erythromycin, clarithromycin or telithromycin is unavoidable, therapy with lovastatin should be suspended during the course of treatment.
Although not studied clinically, voriconazole has been shown to inhibit lovastatin metabolism in vitro (human liver microsomes). Therefore, voriconazole is likely to increase the plasma concentration of lovastatin. It is recommended that dose adjustment of lovastatin be considered during coadministration. Increased lovastatin concentration in plasma has been associated with an increased risk of myopathy/rhabdomyolysis.
Gemfibrozil: The combined use of lovastatin with gemfibrozil should be avoided.
Other fibrates: Caution should be used when prescribing other fibrates with lovastatin, as these agents can cause myopathy when given alone. The benefit of further alterations in lipid levels by the combined use of lovastatin with other fibrates should be carefully weighed against the potential risks of this combination.
Cyclosporine: The use of lovastatin with cyclosporine should be avoided.
Danazol, diltiazem or verapamil with higher doses of lovastatin: In patients taking concomitant danazol, diltiazem or verapamil, the dose of lovastatin should not exceed 20 mg (see DOSAGE AND ADMINISTRATION), as the risk of myopathy increases at higher doses. The benefits of the use of lovastatin in patients receiving danazol, diltiazem, or verapamil should be carefully weighed against the risks of these combinations.
Amiodarone: In patients taking concomitant amiodarone, the dose of lovastatin should not exceed 40 mg (see DOSAGE AND ADMINISTRATION), as the risk of myopathy increases at higher doses.
Colchicine: Cases of myopathy, including rhabdomyolysis, have been reported with lovastatin coadministered with colchicine, and caution should be exercised when prescribing lovastatin with colchicine.
Ranolazine: The risk of myopathy, including rhabdomyolysis, may be increased by concomitant administration of ranolazine. Dose adjustment of lovastatin may be considered during co-administration with ranolazine.
Prescribing recommendations for interacting agents are summarized in Table 9.

Myopathy and/or rhabdomyolysis have been reported when lovastatin is used in combination with lipid-altering doses (≥1g/day) of niacin. Physicians contemplating the use of ADVICOR, a combination of lovastatin and niacin, should weigh the potential benefits and risks, and should carefully monitor patients for any signs and symptoms of muscle pain, tenderness, or weakness, particularly during the initial month of treatment or during any period of upward dosage titration of either drug. Periodic CK determinations may be considered in such situations, but there is no assurance that such monitoring will prevent myopathy.
In clinical studies, no cases of rhabdomyolysis and one suspected case of myopathy have been reported in 1079 patients who were treated with ADVICOR at doses up to 2000 mg/40 mg for periods up to 2 years.
Patients starting therapy with ADVICOR should be advised of the risk of myopathy, and told to report promptly unexplained muscle pain, tenderness, or weakness. A CK level above 10 times ULN in a patient with unexplained muscle symptoms indicates myopathy. ADVICOR therapy should be discontinued if myopathy is diagnosed or suspected.
In patients with complicated medical histories predisposing to rhabdomyolysis, such as preexisting renal insufficiency, dose escalation requires caution. ADVICOR therapy should be discontinued if markedly elevated CPK levels occur or myopathy is diagnosed or suspected. ADVICOR therapy should also be temporarily withheld in any patient experiencing an acute or serious condition predisposing to the development of renal failure secondary to rhabdomyolysis, e.g., sepsis; hypotension; major surgery; trauma; severe metabolic, endocrine, or electrolyte disorders; or uncontrolled epilepsy.

Uses
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 hypercholesterolemia. Drug 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 (see also Table 8 and the NCEP treatment guidelines1).
ADVICOR (niacin extended-release and lovastatin) is indicated for use when treatment with both NIASPAN and lovastatin is appropriate. As described in the labeling for Niaspan and lovastatin below, the components of ADVICOR are both indicated for the treatment of hypercholesterolemia. Patients receiving treatment with ADVICOR should be on a standard cholesterol-lowering diet and should continue on this diet during treatment.
NIASPAN is indicated as an adjunct to diet for reduction of elevated TC, LDL-C, Apo B and TG levels, and to increase HDL-C in patients with primary hypercholesterolemia (heterozygous familial and nonfamilial) and mixed dyslipidemia (Table 7), when the response to an appropriate diet has been inadequate.
In patients with a history of myocardial infarction and hypercholesterolemia, niacin is indicated to reduce the risk of recurrent nonfatal myocardial infarction.
Niacin is also indicated as adjunctive therapy for treatment of adult patients with very high serum triglyceride levels (Table 7) who present a risk of pancreatitis and who do not respond adequately to a determined dietary effort to control them. Such patients typically have serum TG levels over 2000 mg/dL and have elevations of VLDL-C as well as fasting chylomicrons (Table 7). Patients who consistently have total serum or plasma TG below 1000 mg/dL are unlikely to develop pancreatitis. Therapy with niacin may be considered for those patients with TG elevations between 1000 and 2000 mg/dL who have a history of pancreatitis or of recurrent abdominal pain typical of pancreatitis. Some patients with TG under 1000 mg/dL may, through dietary or alcohol indiscretion, convert to a pattern with massive TG elevations accompanying fasting chylomicronemia, but the influence of niacin therapy on risk of pancreatitis in such situations has not been adequately studied. Drug therapy is not indicated for patients with hyperlipoproteinemia, who have elevations of chylomicrons and plasma TG, but who have normal levels of VLDL-C.
Lovastatin is indicated as an adjunct to diet for the reduction of elevated TC and LDL-C levels in patients with primary hypercholesterolemia (Table 7), when the response to diet restricted in saturated fat and cholesterol and to other nonpharmacological measures alone has been inadequate.
In individuals without symptomatic cardiovascular disease, average to moderately elevated TC and LDL-C, and below average HDL-C, lovastatin is indicated to reduce the risk of:
- Myocardial infarction
- Unstable angina
- Coronary revascularization procedures
Lovastatin is also indicated to slow the progression of coronary atherosclerosis in patients with coronary heart disease as part of a treatment strategy to lower TC and LDL-C to target levels.
The National Cholesterol Education Program (NCEP) Treatment Guidelines are summarized below:
| TC = total cholesterol; TG = triglycerides; LDL = low-density lipoprotein; VLDL = very low-density lipoprotein; IDL = intermediate-density lipoprotein ↑→ = increased or no change | |||||
| Table 7. Classification of Hyperlipoproteinemias | |||||
| Type | Lipoproteins Elevated | Lipid Elevations | |||
| I (rare) | Chylomicrons | Major | Minor | ||
| IIa | LDL | TG | ↑→TC | ||
| IIb | LDL,VLDL | TC | - | ||
| III (rare) | IDL | TC | TG | ||
| IV | VLDL | TC/TG | - | ||
| V (rare) | Chylomicrons, VLDL | TG | ↑→TC | ||
Prior to initiating therapy with a lipid-lowering agent, secondary causes for hypercholesterolemia (e.g., poorly controlled diabetes mellitus, hypothyroidism, nephrotic syndrome, dysproteinemias, obstructive liver disease, other drug therapy, alcoholism) should be excluded, and a lipid profile performed to measure TC, HDL-C, and TG. For patients with TG < 400 mg/dL, LDL-C can be estimated using the following equation:
LDL-C = TC - [(0.20 x TG) + HDL-C]
For TG levels > 400 mg/dL, this equation is less accurate and LDL-C concentrations should be determined by ultracentrifugation. Lipid determinations should be performed at intervals of no less than 4 weeks and dosage adjusted according to the patient's response to therapy. The NCEP Treatment Guidelines are summarized in Table 8.
| Table 8. NCEP Treatment Guidelines: LDL-C Goals and Cutpoints for Therapeutic Lifestyle Changes and Drug Therapy in Different Risk Categories | |||
| Risk Category | LDL Goal (mg/dL) |
LDL Level at Which to Initiate Therapeutic Lifestyle Changes (mg/dL) |
LDL Level at Which to Consider Drug Therapy (mg/dL) |
| CHD† or CHD risk equivalents (10-year risk >20%) |
<100 | ≥ 100 | ≥ 130 (100-129:drug optional) †† |
| 2+ Risk factors (10-year risk ≤20%) |
<130 | ≥ 130 | 10-year risk 10%-20%: ≥ 130 10-year risk <10%: ≥ 160 |
| 0-1 Risk factor ††† | <160 | ≥ 160 | ≥ 190 (160-189:LDL-lowering drug optional) |
| † CHD, coronary heart disease †† Some authorities recommend use of LDL-lowering drugs in this category if an LDL-C level of <100 mg/dL cannot be achieved by therapeutic lifestyle changes. Others prefer use of drugs that primarily modify triglycerides and HDL-C, e.g., nicotinic acid or fibrate. Clinical judgement also may call for deferring drug therapy in this subcategory. ††† Almost all people with 0-1 risk factor have 10-year risk <10%; thus, 10-year risk assessment in people with 0-1 risk factor is not necessary. |
|||
After the LDL-C goal has been achieved, if the TG is still ≥200 mg/dL, non-HDL-C (TC minus HDL-C) becomes a secondary target of therapy. Non-HDL-C goals are set 30 mg/dL higher than LDL-C goals for each risk category.

Advicor | Physicians Total Care, Inc.
The patient should be placed on a standard cholesterol-lowering diet before receiving ADVICOR or its individual active components and should continue on this diet during treatment with lipid-altering therapy (see NCEP Treatment Guidelines for details on dietary therapy).
ADVICORADVICOR should be taken at bedtime, with a low-fat snack. ADVICOR tablets should be taken whole and should not be broken, crushed, or chewed before swallowing. Patients not currently on NIASPAN must start ADVICOR at the lowest initial ADVICOR dose, a single 500 mg/20 mg tablet once daily at bedtime. The dose of ADVICOR should not be increased by more than 500 mg daily (based on the NIASPAN component) every 4 weeks. The dose of ADVICOR should be individualized based on targeted goals for cholesterol and triglycerides, and on patient response. Doses of ADVICOR greater than 2000 mg/40 mg daily are not recommended. If ADVICOR therapy is discontinued for an extended period (>7 days), reinstitution of therapy should begin with the lowest dose of ADVICOR.
Flushing of the skin (see ADVERSE REACTIONS) may be reduced in frequency or severity by pretreatment with aspirin up to the recommended dose of 325 mg (taken up to approximately 30 minutes prior to ADVICOR dose). Flushing, pruritus, and gastrointestinal distress are also greatly reduced by slowly increasing the dose of niacin and avoiding administration on an empty stomach.
Equivalent doses of ADVICOR may be substituted for equivalent doses of NIASPAN but should not be substituted for other modified-release (sustained-release or time-release) niacin preparations or immediate-release (crystalline) niacin preparations (see WARNINGS). Patients previously receiving niacin products other than NIASPAN should be started on NIASPAN with the recommended NIASPAN titration schedule, and the dose should subsequently be individualized based on patient response. A relative bioavailability study results indicated that ADVICOR tablet strengths (i.e. two tablets of 500 mg/20 mg and one tablet of 1000 mg/40 mg) are not interchangeable.
NIASPANNIASPAN should be taken at bedtime, after a low-fat snack, and doses should be individualized according to patient response. Therapy with NIASPAN must be initiated at 500mg at bedtime in order to reduce the incidence and severity of side effects which may occur during early therapy. NIASPAN must be titrated and the dose should not be increased by more than 500 mg every 4 weeks up to a maximum dose of 2000 mg a day. The recommended dose escalation is shown in Table 11 below. Patients already receiving a stable dose of NIASPAN may be switched directly to a niacin-equivalent dose of ADVICOR.
Table 11. Recommended Dosing
Maintenance Dose:The daily dosage of NIASPAN should not be increased by more than 500 mg in any 4-week period. The recommended maintenance dose is 1000 mg (two 500 mg tablets) to 2000 mg (two 1000 mg tablets or four 500 mg tablets) once daily at bedtime. Doses greater than 2000 mg daily are not recommended. Women may respond at lower NIASPAN doses than men.
Flushing of the skin (see ADVERSE REACTIONS) may be reduced in frequency or severity by pretreatment with aspirin up to the recommended dose of 325 mg (taken 30 minutes prior to NIASPAN 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 ADVICOR ingestion.
Equivalent doses of NIASPAN should not be substituted for sustained-release (modified-release, timed-release) niacin preparations or immediate-release (crystalline) niacin (see WARNINGS). Patients previously receiving other niacin products should be started with the recommended NIASPAN titration schedule (see Table 11), and the dose should subsequently be individualized based on patient response. Single-dose bioavailability studies have demonstrated that NIASPAN tablet strengths are not interchangeable.
If NIASPAN therapy is discontinued for an extended period, reinstitution of therapy should include a titration phase (see Table 11).
NIASPAN tablets should be taken whole and should not be broken, crushed or chewed before swallowing.
Concomitant Therapy Concomitant Therapy with LovastatinPatients already receiving a stable dose of lovastatin who require further TG-lowering or HDL-raising (e.g., to achieve NCEP non-HDL-C goals), may receive concomitant dosage titration with NIASPAN per NIASPAN recommended initial titration schedule (see Table 10, DOSAGE AND ADMINISTRATION section). For patients already receiving a stable dose of NIASPAN who require further LDL-lowering (e.g., to achieve NCEP LDL-C goals; Table 8), the usual recommended starting dose of lovastatin is 20 mg once a day. Dose adjustments should be made at intervals of 4 weeks or more. Combination therapy with NIASPAN and lovastatin should not exceed doses of 2000 mg and 40 mg daily, respectively.
Dosage in Patients with Renal or Hepatic InsufficiencyUse of NIASPAN in patients with renal or hepatic insufficiency has not been studied. NIASPAN is contraindicated in patients with significant or unexplained hepatic dysfunction (see WARNINGS, PRECAUTIONS. NIASPAN should be used with caution in patients with renal insufficiency (see CLINICAL PHARMACOLOGY).
LovastatinThe usual recommended starting dose is 20 mg once a day given with the evening meal. The recommended dosing range is 10-80 mg/day in single or two divided doses; the maximum recommended dose is 80 mg/day. Doses should be individualized according to the recommended goal of therapy (see NCEP Guidelines and CLINICAL PHARMACOLOGY). Patients requiring reductions in LDL cholesterol of 20% or more to achieve their goal (see INDICATIONS AND USAGE) should be started on 20 mg/day of lovastatin. A starting dose of 10 mg may be considered for patients requiring smaller reductions. Adjustments should be made at intervals of 4 weeks or more.
Cholesterol levels should be monitored periodically and consideration should be given to reducing the dosage of lovastatin if cholesterol levels fall significantly below the targeted range.
Dosage in Patients taking Danazol, Diltiazem or Verapamil
In patients taking danazol, diltiazem, or verapamil concomitantly with lovastatin (see WARNINGS, Myopathy/Rhabdomyolysis), therapy should begin with 10 mg of lovastatin and should not exceed 20 mg/day.
Dosage in Patients taking Amiodarone
In patients taking amiodarone concomitantly with lovastatin, the dose should not exceed 40 mg/day (see WARNINGS, Myopathy/Rhabdomyolysis and PRECAUTIONS, Drug Interactions, Other drug interactions).
Concomitant Lipid-Lowering Therapy
Use of lovastatin with gemfibrozil should be avoided.
Caution should be used when prescribing other fibrates with lovastatin, as fibrates can cause myopathy when given alone.
Dosage in Patients with Renal Insufficiency
In patients with severe renal insufficiency (creatinine clearance <30 mL/min), dosage increases above 20 mg/day should be carefully considered and, if deemed necessary, implemented cautiously (see CLINICAL PHARMACOLOGY and WARNINGS, Myopathy/Rhabdomyolysis).
LovastatinThe usual recommended starting dose is 20 mg once a day given with the evening meal. The recommended dosing range is 10-80 mg/day in single or two divided doses; the maximum recommended dose is 80 mg/day.

The recommended dosing range is 10-80 mg/day in single or two divided doses; the maximum recommended dose is 80 mg/day. Doses should be individualized according to the recommended goal of therapy (see NCEP Guidelines and CLINICAL PHARMACOLOGY). Patients requiring reductions in LDL cholesterol of 20% or more to achieve their goal (see INDICATIONS AND USAGE) should be started on 20 mg/day of lovastatin. A starting dose of 10 mg may be considered for patients requiring smaller reductions. Adjustments should be made at intervals of 4 weeks or more.
Cholesterol levels should be monitored periodically and consideration should be given to reducing the dosage of lovastatin if cholesterol levels fall significantly below the targeted range.
Dosage in Patients taking Danazol, Diltiazem or Verapamil
In patients taking danazol, diltiazem, or verapamil concomitantly with lovastatin (see WARNINGS, Myopathy/Rhabdomyolysis), therapy should begin with 10 mg of lovastatin and should not exceed 20 mg/day.
Dosage in Patients taking Amiodarone
In patients taking amiodarone concomitantly with lovastatin, the dose should not exceed 40 mg/day (see WARNINGS, Myopathy/Rhabdomyolysis and PRECAUTIONS, Drug Interactions, Other drug interactions).
Concomitant Lipid-Lowering Therapy
Use of lovastatin with gemfibrozil should be avoided.
Caution should be used when prescribing other fibrates with lovastatin, as fibrates can cause myopathy when given alone.
Dosage in Patients with Renal Insufficiency
In patients with severe renal insufficiency (creatinine clearance <30 mL/min), dosage increases above 20 mg/day should be carefully considered and, if deemed necessary, implemented cautiously (see CLINICAL PHARMACOLOGY and WARNINGS, Myopathy/Rhabdomyolysis).
