How Gemfibrozil Works

Gemfibrozil works by activating a specific receptor in the body known as PPAR-alpha. This activation helps to reduce triglyceride levels and increase good cholesterol (HDL) in the bloodstream.

By altering the breakdown and removal of fats, it helps to improve overall lipid profiles. This can be beneficial in reducing the risk of developing heart disease.
