Rhabdomyolysis is a life-threatening clinical and biochemical syndrome that results from injury to skeletal muscle. Hydroxymethylglutaryl coenzyme A reductase inhibitors (statins) have been associated with myopathy and rhabdomyolysis. Although rhabdomyolysis is a rare adverse event associated with this class of drugs, their prevalent use in the management of dyslipidemia makes it increasingly important for clinicians to understand the nature of this condition. Rhabdomyolysis can occur with all statins when used alone and particularly when combined with other drugs that are themselves myotoxic or that elevate the concentration of the statin. Statins are particularly susceptible to the latter effect because of their metabolism by the CYP450 system and their low oral bioavailability. In this report, we describe a case of rhabdomyolysis and acute renal failure secondary to the interaction between danazol and simvastatin.
