Pivmecillinam in complicated urinary infections failing to respond to conventional therapy

Abstract

Forty-three patients with a history of recurrent urinary infections, many of whom had renal involvement and had recently failed treatment, were then treated with pivmecillinam (400 mg 8-hourly for seven days). One week after the end of treatment the bacteriological cure rate was 72.1%. During the following four weeks, however, several of the cured patients relapsed, so that the cure rate five weeks after the end of treatment was only 46%. Thus, it is recommended that such patients should begin prophylactic treatment if found to be abacteriuric after the one week follow-up. Pivmecillinam was extremely well tolerated.
