Hypolipidemic agents, or antihyperlipidemic agents, are a diverse group of pharmaceuticals that are used in the treatment of high levels of fats (lipids), such as cholesterol, in the blood (hyperlipidemia). They are called lipid-lowering drugs . Contents. 1 Classes. Established. 2 Research; 3 References; 4 See also.

For example, some may lower the “bad cholesterol” low density lipoprotein LDL more so than others, while others may preferentially increase high density lipoprotein HDL”the good cholesterol”.
In addition, it is the most potent antihyperlipidemic agent for raising plasma HDL levels, which is the most common indication for its clinical use.

Cutaneous flush most common side effects accompanied by an uncomfortable feeling of warmth and pruritus. AtorvastatinFluvastatinLovastatinPravastatinSimvastatin.
Colesevelam Colestilan Colestipol Colestyramine Colextran.
Some antihyperlipidemic agents aim to lower the levels of low-density lipoprotein LDL cholesterol, some reduce triglyceride levels, and some help raise the high-density lipoprotein HDL cholesterol. Fibric acid derivatives may induce a Myopathy and rhabdomyolysis the risk is greater in: In other projects Wikimedia Commons. Describe some antihyperlipidemics obtained from fermentation process. Tetracycline, warfarindigoxinthiazide diuretics, phenobarbitone and thyroid hormones should be taken 1 h-2h before or 4 h-6h after colestyramine to avoid impairment of their absorption Because the drug binds anions.
Because of a circadian rhythm to LDL-receptor synthesis, statins are a little more effective if given in the evening rather than in the morning PowerPoint Presentation: Considerable evidence points to oxidation of LDL as an essential step in the development of atheromaand therefore interest has centred on the role of either endogenous or therapeutic vitamin E in prevention of atheroma. Anti- hyperlipidemic drugs are mainly classified into 5 types: Mechanism of action of statins PowerPoint Presentation: Colesevelam has fewer gastrointestinal side effects and not Impaired absorptions PowerPoint Presentation: Plasma total cholesterol and LDL-cholesterol fall to attain a maximum effect 1 month after therapy.
Plasma creatine kinase levels should be determined regularly.
Niacin is also used to treat other severe hypercholesterolemiasoften in combination with other antihyperlipidemic agents. They have no place in treating hypercholesterolaemia.

Therapeutic uses Hypertriglyceridemia the most effective in reduction TGs – combined hyperlipidemia type Antihypeflipidemic if statins are contraindicated. The most severe hyperlipidaemias usually occur In patients with concurrent conditions, e.

Both ezetimibe and ezetimibe-glucuronide are slowly eliminated from plasma, with a half-life of approximately 22 hours. Anti Hyperlipidemic Drugs DrNajlaa. Hypolipidemic agentsor antihyperlipidemic agentsare a diverse group of pharmaceuticals that are used in the treatment of high levels of fats lipidssuch as cholesterol, in the blood hyperlipidemia. Lipid disorders Disorders of lipid metabolism are manifest by elevation of the plasma concentrations of the various lipid and lipoprotein fractions total and LDL cholesterol, VLDL, triglycerides, chylomicrons and they result in cardiovascular disease and atherosclerosis deposition of fats at walls of arteries, forming plaque.
Administration of aspirin prior to taking niacin decreases the flush, which is prostaglandin mediated. Types of Antihyperlipidemic agents Please refer to the drug classes listed below for further information.

Pharmacokinetic of Ezetimibe Metabolized in the small intestine and liver via glucuronide conjugation a Phase II reactionwith subsequent biliary and renal excretion.

Classufication some new drug classes useful in the treatment of hyperlipidemia and atherosclerosis. Because of a circadian rhythm to LDL-receptor synthesis, statins are a little more effective if given in the evening rather than in the morning. At high doses, cholestyramine and colestipol impair the absorption of the fat-soluble vitamins A, D, E, and K.
Mechanism of action of statins: Clinically, the choice of an agent will depend on the patient’s cholesterol profilecardiovascular riskand the liver and kidney functions of the patient, evaluated against the balancing of classificatoin and benefits of the medications.
