Encyclopedia
Bezafibrate is a fibrate
Fibrate
In pharmacology, the fibrates are a class of amphipathic carboxylic acids. They are used for a range of metabolic disorders, mainly hypercholesterolemia , and are therefore hypolipidemic agents.- Members :...

A drug, broadly speaking, is any substance that, when absorbed into the body of a living organism, alters normal bodily function. There is no single, precise definition, as there are different meanings in drug control law, government regulations, medicine, and colloquial usage.In pharmacology, a...

Mode of action

Like the other fibrates, bezafibrate is an agonist of PPARα
Peroxisome proliferator-activated receptor
In the field of molecular biology, the peroxisome proliferator-activated receptors are a group of nuclear receptor proteins that function as transcription factors regulating the expression of genes...

; some studies suggest it may have some activity on PPARγ and PPARδ as well.

Uses

Bezafibrate improves markers of combined hyperlipidemia
Combined hyperlipidemia
In medicine, combined hyperlipidemia is a commonly occurring form of hypercholesterolemia characterised by increased LDL and triglyceride concentrations, often accompanied by decreased HDL...

, effectively reducing LDL and triglycerides and improving HDL levels. The main effect on cardiovascular morbidity is in patients with the metabolic syndrome
Metabolic syndrome
Metabolic syndrome is a combination of medical disorders that, when occurring together, increase the risk of developing cardiovascular disease and diabetes. It affects one in five people in the United States and prevalence increases with age...

, the features of which are attenuated by bezafibrate. Studies show that in patients with impaired glucose tolerance, bezafibrate may delay progress to diabetes, and in those with insulin resistance
Insulin resistance
Insulin resistance is a physiological condition where the natural hormone insulin becomes less effective at lowering blood sugars. The resulting increase in blood glucose may raise levels outside the normal range and cause adverse health effects, depending on dietary conditions. Certain cell types...
