Drug Interaction Report

The niacin in Advicor has a major potential interaction with Alcoholism.

The use of nicotinic acid and its derivatives is contraindicated in patients with significant or unexplained liver disease. Hepatotoxicity, including biochemical abnormalities of liver function, cholestatic jaundice, increased prothrombin time, and fulminant hepatic necrosis and failure, has been reported during therapy with niacin and niacinamide (nicotinamide), particularly in patients who have substituted sustained-release nicotinic acid products for immediate-release preparations at equivalent dosages. Treatment using pharmacologic dosages (e.g., lipid-lowering dosages) of these agents should be administered cautiously in patients with gallbladder disease or a history of jaundice, liver disease and/or heavy alcohol use. Liver transaminase levels should be evaluated prior to initiation of therapy, every 6 to 12 weeks for the first year, and periodically thereafter (e.g., semiannually). Patients who develop elevated ALT or AST levels during therapy should be monitored until abnormalities resolve. If an increase above 3 times the upper limit of normal persists, therapy should be withdrawn. Liver biopsy should be considered in patients with elevations that persist beyond cessation of therapy.

The lovastatin in Advicor has a major potential interaction with Alcoholism.

The use of most HMG-CoA reductase inhibitors is contraindicated in patients with active liver disease, decompensated cirrhosis, or unexplained persistent elevations of serum transaminases. HMG-CoA reductase inhibitors are extensively metabolized by the liver. Decreased drug metabolism may lead to accumulation and increased risk of toxicity, including biochemical abnormalities of liver function and, rarely, jaundice, hepatitis, cirrhosis, fatty change in the liver, and fulminant hepatic necrosis. Therapy with HMG-CoA reductase inhibitors should be administered cautiously in patients with a history of liver disease and/or heavy alcohol use. A lower initial dosage may be appropriate, and clinical monitoring of liver transaminase levels according to the individual manufacturer product information is recommended. Patients who develop elevated ALT or AST levels during therapy should be monitored until abnormalities resolve. If an increase above 3 times the upper limit of normal persists, consideration should be given to a reduction in dosage or withdrawal of therapy.

The niacin in Advicor has a moderate potential interaction with Angina.

Caution is advised when niacin is used in patients with unstable angina or in the acute phase of myocardial infarction, especially when the patients are also receiving vasoactive drugs such as nitrates, calcium channel blockers, or adrenergic blocking agents.

The lovastatin in Advicor has a moderate potential interaction with Central Nervous System Disorders.

Cognitive impairment (e.g., memory loss, forgetfulness, amnesia, memory impairment, confusion) have been observed in patients receiving statins. The reports are usually not serious, and reversible upon statin discontinuation. Caution is recommended when using these agents in patients with cognitive impairment.

Cannabidiol has a moderate potential interaction with Depression.

Antiepileptic drugs (AEDs) have been associated with an increased risk of suicidal thoughts or behavior in patients taking these drugs for any indication. Pooled analyses of 199 placebo-controlled clinical studies involving the use of 11 different AEDs showed that patients receiving AEDs had approximately twice the risk of suicidal thinking or behavior compared to patients receiving placebo. AEDs should be administered cautiously in patients with depression or other psychiatric disorders; phentermine-topiramate should be avoided in patients with history of suicidal attempts or active suicidal ideation. The risk of suicidal thoughts and behavior should be carefully assessed against the risk of untreated illness, bearing in mind that epilepsy and many other conditions for which AEDs are prescribed are themselves associated with morbidity and mortality and an increased risk of suicidal thoughts and behavior. Patients, caregivers, and families should be alert to the emergence or worsening of signs and symptoms of depression, any unusual changes in mood or behavior, or the emergence of suicidal thoughts or behavior. If patients have symptoms of suicidal ideation or behavior, a dosage reduction or treatment discontinuation should be considered.

The lovastatin in Advicor has a moderate potential interaction with Diabetes Mellitus.

Increases in hemoglobin A1c and fasting serum glucose levels have been reported with the use of certain HMG-CoA reductase inhibitors. Caution should be exercised when using these agents in diabetic patients and close monitoring is recommended.

The niacin in Advicor has a moderate potential interaction with Diabetes Mellitus.

Elevated fasting blood sugars and decreased glucose tolerance have been reported during niacin and niacinamide (nicotinamide) therapy. Patients with diabetes mellitus should be monitored closely during therapy with these agents, and adjustments made accordingly in their antidiabetic regimen.

The niacin in Advicor has a major potential interaction with Gallbladder Disease.

The use of nicotinic acid and its derivatives is contraindicated in patients with significant or unexplained liver disease. Hepatotoxicity, including biochemical abnormalities of liver function, cholestatic jaundice, increased prothrombin time, and fulminant hepatic necrosis and failure, has been reported during therapy with niacin and niacinamide (nicotinamide), particularly in patients who have substituted sustained-release nicotinic acid products for immediate-release preparations at equivalent dosages. Treatment using pharmacologic dosages (e.g., lipid-lowering dosages) of these agents should be administered cautiously in patients with gallbladder disease or a history of jaundice, liver disease and/or heavy alcohol use. Liver transaminase levels should be evaluated prior to initiation of therapy, every 6 to 12 weeks for the first year, and periodically thereafter (e.g., semiannually). Patients who develop elevated ALT or AST levels during therapy should be monitored until abnormalities resolve. If an increase above 3 times the upper limit of normal persists, therapy should be withdrawn. Liver biopsy should be considered in patients with elevations that persist beyond cessation of therapy.

The niacin in Advicor has a moderate potential interaction with Gout.

Niacin and niacinamide (nicotinamide) can compete with uric acid for excretion by the kidney. Hyperuricemia and precipitation of gout have been reported during long-term therapy. Treatment using pharmacologic dosages (e.g., lipid-lowering dosages) of these agents should be administered cautiously in patients with or predisposed to gout.

The niacin in Advicor has a major potential interaction with History, Peptic Ulcer.

The use of niacin and niacinamide (nicotinamide) is contraindicated in patients with active peptic ulcer disease. These agents have been reported to activate peptic ulcer. Treatment should be administered cautiously in patients with a history of peptic ulcer disease. Close observation is advised.

The lovastatin in Advicor has a major potential interaction with Liver Disease.

Cannabidiol has a moderate potential interaction with Liver Disease.

Because of the risk of hepatocellular injury, serum transaminases (ALT and AST) and total bilirubin levels should be measured in all patients prior to starting treatment with cannabidiol. Cannabidiol causes dose-related elevations of liver transaminases, and in controlled studies 13% of patients receiving treatment had elevations above 3 times the ULN. Caution and monitoring is advised in patients with hepatic impairment, which can be at increased risk. Dose adjustment is recommended in patients with moderate (Child-Pugh B) hepatic impairment or severe (Child-Pugh C) hepatic impairment. It may be necessary to have slower dose titration in patients with moderate or severe hepatic impairment than in patients without hepatic impairment. If a patient develops clinical signs or symptoms suggestive of hepatic dysfunction (e.g., unexplained nausea, vomiting, right upper quadrant abdominal pain, fatigue, anorexia, or jaundice and/or dark urine), promptly measure serum transaminases and total bilirubin and interrupt or discontinue treatment with cannabidiol, as appropriate.

The lovastatin in Advicor has a moderate potential interaction with Myoneural Disorder.

HMG-CoA reductase inhibitors may cause myopathy and rhabdomyolysis; acute renal failure secondary to myoglobinuria and rare fatalities have occurred due to rhabdomyolysis in patients treated with statins. The myopathy may be dose-related and is characterized by unexplained muscle weakness, pain, or tenderness accompanied by increases in creatine phosphokinase (CPK) values exceeding 10 times the upper limit of normal. Therapy with HMG-CoA reductase inhibitors should be administered cautiously in patients with preexisting myopathy, in those with predisposing factors for myopathy, or with a history of myoneural disorder, since it may delay the recognition or confound the diagnosis of a drug-induced musculoskeletal effect. Patients should be advised to report promptly any unusual muscle pain, tenderness, or weakness, particularly if accompanied by malaise or fever. Periodic CPK determinations may be considered in some patients, although the value of such monitoring is uncertain. HMG-CoA reductase inhibitor therapy should be withdrawn if markedly elevated CPK levels occur or if drug-related myopathy is diagnosed or suspected.

If patients have symptoms of suicidal ideation or behavior, a dosage reduction or treatment discontinuation should be considered.

The lovastatin in Advicor has a major potential interaction with Renal Dysfunction.

In patients with severe renal impairment (CrCl < 30 mL/min.), the plasma concentrations of total HMG-CoA reductase inhibitors after a single dose of lovastatin may be approximately two-fold higher than those in healthy patients, presumably due to the accumulation of active metabolites. Increased HMG-CoA reductase inhibitory activity may be associated with a greater risk of adverse effects, including hepatic and musculoskeletal toxicities. Therefore, lovastatin dosage increases above 20 mg/day should be considered and implemented cautiously in patients with severe renal impairment. Close clinical monitoring is recommended during therapy.

The lovastatin in Advicor has a moderate potential interaction with Renal Dysfunction.

Some HMG-CoA reductase inhibitors (e.g., fluvastatin) have not been studied in patients with severe renal dysfunction or end-stage renal disease. Some others (e.g., pitavastatin, simvastatin) require a dose reduction when used in this group of patients. Caution and close monitoring are advised when using these drugs in patients with renal dysfunction.
