Review of clinical experience in the United States with cefpodoxime proxetil in adults with uncomplicated urinary tract infections.Drugs. 1991; 42 Suppl 3:41-50.D
Two controlled United States trials compared the safety and efficacy of cefpodoxime proxetil (100mg twice daily) with either cefaclor (250mg 3 times daily) or amoxicillin (250mg 3 times daily) in patients with uncomplicated urinary tract infections. Treatment duration was 7 days. 307 of 762 patients treated with cefpodoxime proxetil, 99 of 190 treated with cefaclor, and 57 of 185 treated with amoxicillin were evaluable for efficacy. 311, 99 and 59 pathogens were isolated from cefpodoxime proxetil, cefaclor and amoxicillin patients, respectively, the most common pathogens being Escherichia coli, Klebsiella spp., Proteus mirabilis, and Staphylococcus saprophyticus. Bacteriological cure rates were 80% (247/307), 82% (81/99) and 70% (40/57) for cefpodoxime proxetil, cefaclor and amoxicillin, respectively. Respective clinical cure rates were 79% (242/307), 79% (78/99) and 72% (41/57). Cefpodoxime proxetil was well tolerated, and there was no significant difference between the groups in the overall incidence of adverse experiences. Thus, cefpodoxime proxetil is efficacious and safe in the treatment of patients with uncomplicated urinary tract infections and compares favourably with cefaclor and amoxicillin.
