A case of fenoverine-induced rhabdomyolysis in diabetic nephropathy / 대한내과학회지

ABSTRACT

Fenoverine is a non-atropine like spasmolytic drug that inhibits calcium channel currents in the smooth muscle. It has been occassionally reported that fenoverine can cause rhabdomyolysis under the certain conditions such as hepatic dysfunction, concomitant use of HMG-CoA reductase, mitochondrial myopathy, lipid storage myopathy or malignant hyperthermia. However, there is no report of fenoverine-induced rhabdomyolysis in type 2 diabetic nephropathy patient. So we describe here a case of fenoverine-induced rhabdomyolysis in type 2 diabetic patient. A 70-year-old man had both lower legs and shoulder pain for 5 days prior to hospital admission. He was a type 2 diabetic patient and had been managed for diabetic nephropathy. He had been consumed common doses of fenoverine for 20 days due to abdominal pain and diarrhea. Results of investigations showed evidence of rhabdomyolysis. Fenoverine therapy was stopped after admission and he was treated supportive care, his condition was recovered. In this case, renal function impairment may have been a predisposing factor for fenoverine-induced rhabdomyolysis. The incidence of muscular complications of fenoverine therapy could be reduced by avoidance of prescription of the drug in patients with diabetic nephropathy.
