[A case of theophylline-induced rhabdomyolysis following therapy of bronchial asthma].

A case of a 81-year-old asthmatic male with Theophylline-induced rhabdomyolysis was reported. After intravenous administration of 250 mg of Aminophylline, he developed muscle weakness in the lower extremities. Serum CPK was 31,450 IU, and other enzymes escaping from skeletal muscles were elevated. Serum and urine myoglobin were also elevated. Cessation of Theophylline administration and conservative therapy resulted in improvement of rhabdomyolysis without concomitant acute renal failure.
