Lovastatin
Uses of Lovastatin
Lovastatin is used to manage high cholesterol levels. It belongs to the class of lipid-lowering medications known as statins.
Besides managing cholesterol, Lovastatin is also used to prevent heart attacks and strokes in individuals who have high cholesterol levels and other risk factors. It is primarily indicated when diet and lifestyle modifications alone have not been sufficient in lowering cholesterol levels.

How Lovastatin works
Lovastatin is a cholesterol-lowering medicine, categorised as a statin.
It operates by competitively inhibiting an enzyme called HMG-CoA reductase. This enzyme plays a key role in the production of cholesterol in the body. By blocking this enzyme, Lovastatin effectively reduces the production of 'bad' cholesterol, also known as low-density lipoprotein (LDL).
Additionally, Lovastatin can slightly boost levels of 'good' cholesterol, or high-density lipoprotein (HDL). This balance between lowering LDL and raising HDL contributes to a reduced risk of heart disease and stroke.
