The antibacterial activities of ticarcillin, carbenicillin, tobramycin, and gentamicin and of combinations of these antibiotics were measured against Pseudomonas aeruginosa and other gram-negative bacilli in vitro and in experimental mouse infections. Synergistic effects were produced by the penicillin/aminoglycoside combinations in growth inhibition tests and in bactericidal tests against many of the bacteria tested. Combinations of ticarcillin + tobramycin were more active in vitro than carbenicillin + gentamicin against P. aeruginosa but were no more active than the latter against other gram-negative bacilli. Ticarcillin + tobramycin and carbenicillin + gentamicin also demonstrated synergistic activities against P. aeruginosa, Escherichia coli, and Enterobacter cloacae in experimental mouse infection models. Thus, the penicillin/aminoglycoside combinations produced greater protective effects than the individual antibiotics against lethal intraperitoneal infections and also were more effective in reducing kidney counts of viable bacteria and kidney abscess formation in experimental pyelonephritis infections. As was the case in vitro, ticarcillin + tobramycin was more effective than carbenicillin + gentamicin against the experimental P. aeruginosa infections. The results of these in vitro and in vivo studies suggest that combined therapy with ticarcillin and tobramycin may be warranted in the treatment of serious infections due to P. aeruginosa and Enterobacteriaceae.

An open study was conducted to evaluate the safety and effectiveness of ticarcillin plus clavulanic acid in the treatment of 18 adult women with community-acquired Escherichia coli acute pyelonephritis. Eleven of the 18 patients had a history of urinary tract infections, primarily acute pyelonephritis. Six patients had blood culture results positive for E. coli in addition to positive urine culture results. Ticarcillin plus clavulanic acid was administered as the 3.2 g formulation to 11 patients and as the 3.1 g formulation to the other seven. The mean duration of treatment was 9.2 days. Five of the 18 (28 percent) patients had clinical and bacteriologic cures; there were 11 (69 percent) relapses or reinfections and two (11 percent) clinical failures. Adverse reactions (all reversible) were reported in 11 (61 percent) patients, the most frequent of which was phlebitis. These results should prompt further investigation into the treatment of acute pyelonephritis with ticarcillin plus clavulanic acid versus other antibiotics.
