Lovastatin is a prescription drug. It comes as an immediate-release tablet and an extended-release tablet. An immediate-release drug goes into your bloodstream right away. An extended-release drug is slowly released into your bloodstream over time. Both of these tablets are taken by mouth.
The extended-release tablets are available as the brand-name drug Altoprev. The immediate-release tablets are available as a generic drug. Generic drugs usually cost less than the brand-name version. In some cases, they may not be available in every strength or form as the brand-name drug.
Lovastatin may be used as part of a combination therapy. This means you may need to take it with other medications.
Why it’s used
Lovastatin is used to decrease the amount of cholesterol and other fatty substances in your blood. If cholesterol builds up in your arteries, it may block the flow of blood to your heart, brain, or other parts of your body. This raises your risk of serious problems, such as a heart attack or stroke. Lowering your cholesterol level lowers these risks.
Also, if you have heart disease or are at an increased risk of it, this drug can help reduce the likelihood that you will need heart surgery.
How it works
Lovastatin belongs to a class of drugs called HMG-CoA reductase inhibitors. These are also called statins. A class of drugs is a group of medications that work in a similar way. These drugs are often used to treat similar conditions.
Lovastatin works by slowing the production of cholesterol in your body.
