Tradename: Baycol. Removed from US market 2001 [3] Withdrawn from worldwide market Aug 8, 2001 [2]. Indications: - adjunct to diet in treatment of primary hypercholesterolemia & mixed dyslipidemia Contraindications: 1) pregnancy or lactation 2) hepatic disease 3) concurrent administration of GEMFIBROZIL (Lopid) Dosage: 1) 0.4 mg QD in the evening 2) may be given with or without food Tabs: 0.2, 0.3, 0.4 mg. store tabs below 77 degrees F; protect from moisture. Dosage adjustment in renal failure: - creatinine clearance < 60 mL/min, start 0.2-0.3 mg QD Pharmacokinetics: 1) absolute bioavailability is 60% 2) metabolized to pharmacologically active metabolites a) demethylation b) hydroxylation c) metabolized by cyt P450 3A4 3) eliminated in the urine & feces as metabolites 4) terminal elimination 1/2life is 2-3 hours 5) effects on cholesterol seen in 1 week 6) maximal effects on cholesterol seen in 4 weeks 7) time to peak serum concentration 2.5 hours 8) peak serum levels: 0.2 mg 2.4 ug/L; 0.3 mg 3.8 ug/L; 0/4 mg 5.5 ug/L 9) linear elimination kinetics 0.04-0.4 mg QD 10) protein-binding > 99% 11) volume of distribution 0.3 L/kg Monitor: 1) liver function tests: initially, at 6 & 12 weeks, then semiannually 2) creatine kinase as indicated Adverse effects: 1) similar to other statins 2) common a) dyspepsia b) diarrhea c) arthralgia d) myalgia 3) cardiovascular (2%) - chest pain, peripheral edema 4) headache 5) gastrointestinal - abdominal pain, dyspepsia (6%), diarrhea (4%) 6) genitourinary - RHABDOMYOLYSIS with acute renal failure (reason for removal from US market) [3] 7) mild elevations in serum transaminases 8) musculoskeletal a) increases in creatine kinase (5X) b) rhabdomyolysis 0.05% [4] Drug interactions: 1) in combination with GEMFIBROZIL increases incidence of RHABDOMYOLYSIS to 9% [4] 2) zidovudine: mild increased in zidovudine level 3) cholestyramine decreases availability of cerivastatin 4) increased risk of rhabdomyolysis with - cyclosporine, erythromycin, gemfibrozil, fluconazole, itraconazole, ketoconazole, mibefradil, niacin 5) any drug which inhibits cyt P450 3A4 can increase cerivastatin levels 6) any drug which induces cyt P450 3A4 can diminish cerivastatin levels Mechanism of action: 1) inhibition of HMG CoA reductase 2) maximal effect (0.3 mg/day) a) total cholesterol: decrease of 19% b) LDL cholesterol: decrease of 28% c) HDL cholesterol: increase of 10% d) triglycerides: decrease of 13%
