<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 drugsHMG-CoA reductase iuhibitors 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.5.Other - Probucol, Gugulipid, Ezetimibe, Avasimibe, Torcetrapib.o Ezetimibe inhibits intestinal cholesterole absorption.o Avasimibe inhibits enzyme acyl Coenzyme A : cholesterol acyl transferase-1 ACAT-1 which causes esterification of cholesterol.o Torcetrapib inhibits cholesterol ester triglyceride transport protein - HDL cholesterol.
