Clinical experience with indanyl carbenicillin in urinary tract infections.

SummaryA trial was carried out in 30 patients to assess the effectiveness of indanyl carbenicillin in acute or chronic urinary tract infections, many of which were complicated by a pathological urological or medical condition. In all patients, infection was due to a single species of pathogen: E. coli (19), Proteus (6), and Pseudomonas (5). Oral doses of 1 g indanyl carbenicillin were given 6-hourlyfor an average of 10 days.Results showed a clinical and bacteriological cure in 13 {43.8 %)patients. In 6 patients, although there was initial clinical improvement, the pathogen developed resistance during therapy. In 7 patients, there was super-infection with another organism. Four patients were withdrawn early in treatment because of side-effects, mainly gastrointestinal in origin. Indanyl carbenicillin proved very effective in eradicating all strains of Proteus and Pseudomonas and 12 (70.6%) of the 17 strains of E. coli in patients completing the full course of treatment.
