sultamicillin and Cystitis

An open multicenter study was carried out to evaluate the efficacy and safety of sultamicillin in patients with urinary tract infections or gonococcal urethritis. 1) Sultamicillin (750-2250 mg/day) was administered for 3 d to 196 patients with acute uncomplicated cystitis. The most common dosage regimen was 375 mg three times daily. The results of treatment based on the combination of changes in symptoms, pyuria and bacteriuria were excellent in 66.8%, moderate in 30.6% and poor in 2.6% of cases. Of 203 strains isolated before treatment, 185 (91.1%) were eradicated. The eradication rate for E. coli, the most common pathogen (167 strains), was 92.2%. 2) In total, 368 patients with complicated urinary tract infections were treated with 750-2250 mg/d of sultamicillin for 5 d. The most common dosage regimens were 375 mg three times daily and 750 mg twice daily. The clinical results based on the combination of changes in pyuria and bacteriuria were excellent in 30.4%, moderate in 35.6% and poor in 34.0% of cases. Of 470 strains isolated before treatment, 352 (74.9%) were eradicated. The eradication rate achieved with high beta-lactamase-producing organisms (64.1%) was not significantly different from that achieved with low or non-producers (75.6%). 3) Sultamicillin (750-3000 mg/d) was administered to 367 male patients with gonococcal urethritis for 3 to 7 d. The eradication rate ranged from 92.3% with 750 mg/d to 100% with greater than or equal to 1500 mg/d. The effect of dose was particularly evident with the 27 strains of gonococci that had penicillinase activity.(ABSTRACT TRUNCATED AT 250 WORDS)

Clinical studies of sultamicillin (SBTPC) fine granules, an oral antibiotic with ester linked ampicillin and beta-lactamase inhibitor, sulbactam, were performed in acute uncomplicated cystitis and complicated urinary tract infections. 1. SBTPC fine granules were administrated at a dose of 187.5 mg 2-3 times daily for 5-7 days to 6 patients with acute uncomplicated cystitis. Clinical efficacies as judged according to the criteria of the UTI Committee were excellent in 5 cases and moderate in 1 case with an effectiveness rate of 100%. All of 7 identified bacteria were eradicated by the treatment. 2. SBTPC fine granules were administrated at a dose of 187.5 mg or 375 mg 3 times daily for 5-7 days to 17 patients with complicated urinary tract infections. Clinical efficacies as judged according to the criteria of the UTI Committee were excellent in 8 cases, moderate in 4 cases and poor in 5 cases with an effectiveness rate of 70.6%. Out of 17 identified bacteria, 14 (82.4%) were eradicated by the treatment. 3. As adverse reactions, glossitis, diarrhea and pharyngeal redness were observed in 1 case out of 31 cases treated with the drug. These symptoms, however, were mild and transient. No abnormal laboratory test values were observed. From the above results, it appears that SBTPC fine granules are useful in the treatment of urinary tract infections.
