<prompt> Hypolipidemic drugs act on all except ?HMG Co A reductaseLipoprotein lipaseAcyl CoA, cholesterol acyl transferase 1Peripheral decarboxylase  <response>: Ans. is d i.e., Peripheral decarboxylase Hypolipidemic drugs HMG-CoA reductase inhibitors statins - Lovastatin, Simvastatin, Pravastatin, Atorvastatin, Rosuvastatin. Bile acid sequestrants Resins - cholestyramine, colestipol. Activate lipoprotein lipase fibric acid derivatives - clofibrate, gemfibrozil, bezafibrate, fenofibrate. Inhibit lipolysis and triglyceride synthesis - Nicotinic acid. Other - Probucol, Gugulipid, Ezetimibe, Avasimibe, Torcetrapib. Ezetimibe inhibits intestinal cholesterole absorption. Avasimibe inhibits enzyme acyl Coenzyme A : cholesterol acyl transferase-1 ACAT-1 which causes esterification of cholesterol. Torcetrapib inhibits cholesterol ester triglyceride transpo protein - T HDL cholesterol.
