ESSENTIALS of medical PHARMOCOLOGY SEVENTH EDITION KD TRIPATHI Page :636,637 Impoant statins are :lovastatin Simvastain, pravastatin, rosuvastatin etc Rosuvastatin This is the latest and the most potent statin (10 mg rosuvastatin :::::. 20 mg atorvastatin), with a plasma tlh. of 18-24 hours. Greater LDL-CH reduction can be obtained in severe hypercholesterolaemia; paly due to its longer persistence in the plasma. In patients with raised TG levels, rosuvastatin raises HDL-CH by 15--20% (greater rise than other statins). Dose: Sta with 5 mg OD, increase if needed upto 20 mg/ day, (max 40 mg/ day) ROSUV AS, ROSYN 5, 10, 20 mg tabs. Adverse effects All statins are remarkably well tolerated; overall incidence of side effects not differing from placebo. Notable side effects are: * Headache, nausea, bowel upset, rashes. * Sleep disturbances (probably more with lipophilic drugs). * Rise in serum transaminase can occur, but liver damage is rare. * Muscle tenderness and rise in CPK levels occurs infrequently. Myopathy is the only serious reaction, but is rare ( < 1 per 1000). Few fatalities due to rhabdomyolysis are on record. Myopathy is more common when nicotinic acid/ gemfibrozil or CYP3A4 inhibitor- ketoconazole I erythromycin/ cyclosporine I HIV protease inhibitor is given concurrently. Gemfibrozil inhibits the hepatic uptake of statins by the organic anion traspoer OATP2.it must not be given to pregnant ladies. Uesd in primary hyperlipipidemias.
