Introduction

Gemfibrozil is a prescription medication used to reduce cholesterol levels and treat hypertriglyceridemia (high levels of triglycerides in the blood). It belongs to a class of drugs called fibrates which can help to decrease triglycerides, increase "good" cholesterol (HDL) and slow the buildup of fatty substances in the arteries.

Uses

Gemfibrozil is approved by the U.S Food and Drug Administration to be used in adults to lower triglyceride levels and/or total cholesterol levels. It is used in combination with diet to reduce the risk of coronary heart disease and associated symptoms such as heart attack and stroke. The drug may be used to control levels of non-HDL cholesterol and lipoprotein(a).

Mechanism of Action

Gemfibrozil works by affecting the metabolism of certain fats and lipids released by the liver. It helps to reduce the production of triglycerides, raise the level of “good” cholesterol (HDL) and prevent the build-up of fatty substances in the arteries.
