An ampicillin-sulbactam combination was compared with ampicillin alone, chloramphenicol, clindamycin, and metronidazole against 272 strains of anaerobic bacteria. Chloramphenicol and ampicillin-sulbactam were the most effective, inhibiting 98 to 99% of strains tested at breakpoint (16 micrograms/ml). The combination of sulbactam and ampicillin was much more effective than ampicillin alone again...

The pharmacokinetics of ampicillin and sulbactam, a new beta-lactamase inhibitor, were investigated in 16 patients undergoing prosthetic cardiac valve insertion. The combination of 2 g of ampicillin and 1 g of sulbactam was administered as perioperative prophylaxis intravenously over 3 to 6 days. Several serum pharmacokinetic parameters were similar for the two drugs after three intravenous dos...

OBJECTIVE The safety and efficacy of ampicillin plus sulbactam were compared with those of cefoxitin in the treatment of women with pelvic inflammatory disease (PID). METHODS This single-site, randomized, prospective, third-party-blinded, comparative, parallel-treatment study enrolled 93 women with a diagnosis of PID. Patients were treated with either ampicillin/sulbactam (2 g/1 g, administer...

The activity of cefoperazone/sulbactam was compared with eleven other antimicrobial agents against 91 strains of the Bacteroides fragilis group known to be resistant to clindamycin and/or beta-lactam agents. Sulbactam alone possessed moderate activity against most strains and improved the activity of cefoperazone and ampicillin. Bacteroides distasonis strains were more resistant than other spec...

The inactivation kinetics for inhibition by sulbactam (CP45,899) of Citrobacter freundii GN346 cephalosporinase were studied in detail and compared with those of type Ib penicillinase or TEM-2 beta-lactamase mediated by R plasmid RGN823. The rate constant for progressive inactivation of the cephalosporinase was significantly larger than that measured with the penicillinase. The number of sulbac...

This study investigated the in vitro activity of colistin or sulbactam in combination with fosfomycin or imipenem against eight strains of carbapenem-resistant A. baumannii (CRAB). The eight CRAB clinical isolates were collected from hospitalized patients admitted to Songklanagarind Hospital in southern Thailand during January-December 2008. The isolates were divided into 4 different patterns o...

OBJECTIVE To perform a bioequivalence study of the two 1.5 g cefoperazone (1.0 g) and sulbactam (0.5 g) between Cefper and Sulperazon injections. MATERIAL AND METHOD The present study was performed in 24 Thai healthy male volunteers who were intramuscularly injected a single dose of 1.5 g cefoperazone and sulbactam. A single dose, two periods, two sequences, double blind randomized crossover ...

Acinetobacter baumannii is an important nosocomial pathogen usually in the context of serious underlying disease. Multidrug resistance in these organisms is frequent. The -lactamase inhibitors clavulanic acid, sulbactam, and tazobactam have intrinsic activity against Acinetobacter strains. To evaluate their potential therapeutic usefulness, we determined the in vitro activity of ampicillin, sul...

The pharmacokinetic behaviour of an ampicillin/sulbactam (2:1) combination was studied after intramuscular administration of a single dose (20 mg/kg body weight: 13.33 mg/kg of ampicillin and 6.67 mg/kg of sulbactam) to six sheep and six goats. The objective was to determine whether there were differences between sheep and goats in the disposition profiles of ampicillin and sulbactam. The dispo...

Objective: To explore the antibacterial activity of combined use Shuanghuanglian and cefoperazone sulbactam sodium on resistant strains Pseudomonas aeruginosa. Methods: The aeruginosa which were sensitive to selected prepare different test bacterial solutions respectively; experimental liquid Cefoperazone Sulbactam Sodium prepared separately set as groups control groups; Drug Sensitivity Tests ...
