Statins differ in several ways. The most obvious difference is in their ability to reduce cholesterol. Currently, atorvastatin (Lipitor) and rosuvastatin (Crestor) are the most potent, and fluvastatin (Lescol) is the least potent.
The statins also differ in how strongly they interact with other drugs. Specifically, pravastatin (Pravachol) and rosuvastatin (Crestor) levels in the body are less likely to be elevated by other drugs that may be taken at the same time as the statins. This is so because the enzymes in the liver that eliminate pravastatin and rosuvastatin are not blocked by many of the drugs that block the enzymes that eliminate other statins. This prevents the levels of pravastatin and rosuvastatin from rising and leading to increased toxicity such as myopathy (inflammation of the muscles). For example, in scientific studies, patients who took both verapamil (Calan, Verelan, Verelan PM, Isoptin, Isoptin SR, Covera-HS) and simvastatin (Zocor) experienced myopathy 10 times more often than patients who received simvastatin alone because verapamil increased the blood levels of simvastatin.
Statins differ in the frequency with which they cause a severe type of myopathy called rhabdomyolysis, in which muscles are severely damaged. Cerivastatin (Baycol) was withdrawn from pharmacies worldwide because it caused rhabdomyolysis 10 to 100 times more often than other statins. Rhabdomyolysis may occur more often in patients taking statins with drugs that also cause rhabdomyolysis or drugs that increase the blood concentration of the statin.
