The prevention of cyclophosphamide-induced cystitis in mice by disulfiram.

Cyclophosphamide administered intraperitoneally to mice at a dose of 100 mg/kg caused a dose related increase in urinary bladder weight within 48 hours of treatment. Disulfiram effectively prevented cyclophosphamide-induced increase in bladder weight when disulfiram was administered by either the oral or intraperitoneal route. Disulfiram (125 mg/kg) was most effective when given within one hour of cyclophosphamide treatment. These results suggest that disulfiram, unlike other putative protectants, is effective when administered orally.
