[Rhabdomyolysis and severe hepatotoxicity due to a drug-drug interaction between ritonavir and simvastatin. Could we use the most cost-effective statin in all human immunodeficiency virus-infected patients?].

Introduction: Drugs like statins may induce rhabdomyolysis. Simvastatin and lovastatin have a high hepatic metabolism and their potential toxicity could be increased by interactions with other drugs that reduce their metabolism.

Patients And Methods: A case-report is presented of an HIV-infected patient treated with antiretroviral drugs who developed a rhabdomyolysis-induced renal failure and liver toxicity when simvastatin was substituted for atorvastatin.
