Gemfibrozil is a lipid-regulating drug classified as a fibric acid derivative, used primarily for the treatment of hyperlipidemia and hypertriglyceridemia. It is indicated to reduce cardiovascular risk in dyslipidemic patients, particularly those with high triglycerides. Gemfibrozil is still approved and in clinical use today.
