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 . The sites of action of several antihyperlipidemic drugs are shown. .. on LDL cholesterol, they are often combined with other antilipidemic drugs for treatment of.

By reducing the LDL cholesterol, they can prevent both the primary and secondary symptoms of coronary heart disease. The sites of action of several antihyperlipidemic antilipidemmic are shown. Whereas plaques can slowly occlude coronary and cerebral vessels, clinical symptoms are more frequently precipitated by rupture of unstable plaques, leading to occlusive thrombi.
For identification of abbreviations of the lipoproteins, some drug classes, and additional discussion, see text.
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”.

Atherosclerosis is the abnormal accumulation of lipids and products resulting from an inflammatory response in the walls of arteries, and is the leading cause of death in the Western world. Jump to a Section Antihyperlipidemic Drugs: HDL participates in pathways that retrieve cholesterol from the artery wall and inhibit the oxidation of atherogenic lipoproteins.
Besides small molecules for novel targets, biological drugs such as monoclonal antibodies, antisense or gene-silencing oligonucleotides, peptidomimetics, reconstituted synthetic HDL particles and therapeutic proteins are novel approaches in clinical development are which have to be applied by injection or infusion.
In contrast, uptake by scavenger receptors is an unregulated process that can overwhelm the ability of a cell to sequester potentially toxic lipids safely. They may differ in both their impact on the cholesterol profile and adverse effects.
Major focus lies on approaches to LDL-lowering drugs superior to statins with regard to efficacy, safety, and patient compliance and on approaches modifying antilipdiemic levels and functionality of HDL particles based on the clinically validated inverse relationship between high-plasma HDL levels and the risk for CVD. Available for Android and iOS devices. They are called lipid-lowering drugs.
Repatha is antiljpidemic as a mg injection every other week or as a monthly injection of mg. Pop-up div Successfully Displayed This div only appears when the trigger link is hovered over.

The five drug classes discussed in this chapter Figure 26—1 are used to decrease serum concentrations of lipids in the blood hyperlipidemia and to prevent or reverse associated atherosclerosis, or, in the case of hypertriglyceridemia, prevent pancreatitis.
Decongestants Bronchodilators Cough medicines H 1 antagonists. The companies are conducting cardiovascular outcomes trials to determine whether their ability to dramatically lower bad LDL cholesterol will lead to fewer heart attacks, strokes and deaths. Praluent is given every other week by injection in doses of 75 mg or mg.

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 wntilipidemic balancing of risks and benefits of the medications.

The armamentarium for the treatment of dyslipidemia today comprises six different modes of action with overall around 24 different drugs. 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.
From Wikipedia, the free encyclopedia. Macrophages in arterial walls use scavenger receptors to take up circulating lipoproteins, especially particles with apolipoproteins that have been modified by free radicals. Sign in via Shibboleth.
