Statin

Rosuvastatin

A statin with strong uptake into the liver, used to lower LDL cholesterol and triglycerides and to prevent heart attack and stroke.

Drug card

Class
Statin
How it works
Blocking HMG-CoA reductase, so the liver makes less cholesterol
Used for
  • High LDL cholesterol, including familial forms
  • Lowering heart attack and stroke risk in at-risk adults
  • High triglycerides (with diet)
Known for
  • Muscle aches (myalgia)
  • Myopathy and rhabdomyolysis
Its name
-vastatin means a statin (HMG-CoA reductase inhibitor)

Study it as a flashcard, and it comes back before you forget it.

Mechanism of action

How does rosuvastatin work?

A selective, competitive HMG-CoA reductase inhibitor that is taken up readily by the liver, its target organ. It adds hepatic LDL receptors and cuts the liver's VLDL output, so fewer VLDL and LDL particles circulate. Only about 10% is metabolized, mostly by CYP2C9; its half-life is about 19 hours.

Like other statins: Statins competitively inhibit HMG-CoA reductase, the enzyme that sets the pace of cholesterol synthesis by turning HMG-CoA into mevalonate. Short of cholesterol, liver cells put more LDL receptors on their surface and take up more LDL from the blood, and the liver releases less VLDL. Plasma LDL cholesterol falls, and with it the risk of heart attack and stroke.

Watch for

Cautions and what sets it apart

  • Asian patients reach about twice the blood levels and may have more myopathy, so treatment starts at the lowest dose.
  • Cyclosporine, darolutamide, regorafenib, gemfibrozil and several HIV and hepatitis C antivirals raise its levels: limit the dose or avoid.
  • With warfarin it can raise the INR: check the INR before starting and until it is stable.
  • Contraindicated in acute liver failure or decompensated cirrhosis; stop it in pregnancy and avoid breastfeeding.

Good to know: Barely metabolized and long-acting; people of Asian descent, including South Asians, reach about double the exposure, so lower starting doses are used.

Remember it

A way to remember it

Statins shut the cholesterol factory, and the liver goes shopping for LDL.

With HMG-CoA reductase blocked, liver cells make less cholesterol and add LDL receptors to pull LDL out of the blood. The harms to watch for are in the muscles (myalgia, rhabdomyolysis) and the liver.

Its name

  • -vastatin means statin (HMG-CoA reductase inhibitor)

    Atorvastatin, simvastatin, rosuvastatin and pravastatin block HMG-CoA reductase. WHO files the stem under -stat (enzyme inhibitors); nystatin, an antifungal, is not a statin.
