    Flashcards

    What do statins do?

    Statins inhibit HMG CoA reductase, an enzyme involved in cholesterol production, reducing cholesterol levels in the body, and also increase the removal of LDL cholesterol.

    How do statins work?

    Statins work by blocking the enzyme HMG CoA reductase, which is a crucial step in the production of cholesterol, causing cholesterol to decrease, thereby improving lipid profile.

    What are common side effects of statins?

    Common side effects of statins include muscle pain, inflammation of the muscles (myositis), muscle breakdown (rhabdomyolysis), and possible liver issues.

    When are statins typically prescribed?

    Statins are usually prescribed once daily, often in the evening or bedtime.
