title: Skeletal muscle weakness resulting from quinidine ingestion.
abstract: We have described a patient with muscle weakness caused by ingestion of quinidine sulfate. Intrafascicular perivasculitis and rare muscle fiber regeneration were present in the muscle at biopsy. A similar clinical picture has previously been reported in patients taking other medications, but not quinidine.
