Neuromuscular Complications of Statins

Statins, 3-hydroxy-3-methlglutaryl coenzyme A reductase inhibitors, are commonly prescribed for patients who have hyperlipidemia. Statins were first approved in 1987. Statin therapy is well documented to reduce serum low-density lipoprotein levels, incidence of cardiovascular events, and mortality. Although statin therapy is well tolerated, serious adverse affects have been reported, including neuromuscular and hepatic complications. Myopathy is particularly concerning because of the potential for rhabdomyolysis and death. Recently, peripheral neuropathy also has been identified as a possible complication. The incidence of neuromuscular complications is expected to increase with the increased number of people using statin therapy. Clinicians should be aware of the potential neuromuscular complications. This article reviews epidemiology, possible mechanisms, risk factors, and management of statin-associated neuromuscular complications.
