Fenoverine-induced rhabdomyolysis.
Fenoverine is a spasmolytic drug that inhibits calcium channel currents. We describe the clinicopathologic findings in two patients with fenoverine-induced rhabdomyolysis, of whom one died. A transient left-bundle-branch block was observed in both patients. In one case, pre-existing hepatic dysfunction may have induced accumulation of the drug. Concurrent treatment by fibrates, as observed in the second patient, 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 hepatopathy or those being treated with cholesterol-lowering agents. Physicians should be aware of life-threatening adverse effects of apparently innocuous drugs.
