Statin-Induced Rhabdomyolysis Due to Pharmacokinetic Changes From Biliary Obstruction in a Patient With Metastatic Prostate Cancer

Abstract

Statins work synergistically with androgen receptor blockers and androgen biosynthesis inhibitors, improving survival in patients with metastatic castration resistant prostate cancers (mCRPCs). Survival improvement is more pronounced for patients receiving androgen biosynthesis inhibitors compared with patients receiving androgen receptor blockers. A rare adverse interaction between simvastatin and abiraterone (Zytiga), an androgen biosynthesis inhibitor, was observed in a patient with mCRPC due to pharmacokinetic changes resulting from obstructive jaundice.
