A man being treated with CAPD developed severe hyperkalemia associated with clofibrate-induced rhabdomyolysis. A total intake of 9.5 9 of clofibrate was complicated by a 100fold increase of CPK, a dramatic increase in muscular enzymes and a life-threatening serum K level of 7.9 mEq/l. Despite a significant peritoneal elimination of clofibrate, this man exhibited a supranormal serum level of free drug.
