Tobramycin serum, thoracic lymph, renal lymph, and urine concentrations were measured in mongrel dogs after intravenously administered 5, 10, and 20 mg/kg doses. These were compared with intravenous gentamicin delivered at 5 and 20 mg/kg. Both drugs achieved similar concentrations in serum and thoracic lymph. At 20 mg/kg, tobramycin showed consistently higher renal lymph and urine concentration...

The objectives of this study were to investigate the bactericidal activity in serum of cefotaxime alone or in combination with tobramycin against clinical strains and to determine the influence of tobramycin on the pharmacokinetics of cefotaxime. The peak bactericidal activity in serum of cefotaxime alone against Klebsiella oxytoca, Enterobacter aerogenes, Serratia marcescens, Pseudomonas cepac...

The stability of the aminoglycosides gentamicin, tobramycin, and amikacin stored in combination with carbenicillin, piperacillin, cefotaxime, and moxalactam was evaluated at four temperatures (25, 4, -8, and -70 degrees C) over a 3-week period. Amikacin was the most stable of the aminoglycosides and demonstrated no loss of activity when stored with either carbenicillin or piperacillin. Gentamic...

In a prospective, randomized, multicenter study, the efficacy and safety of cefoperazone and the combination ampicillin-tobramycin as initial therapy for patients with severe acute biliary tract infections were compared. Of 77 patients initially entered in the study, definite severe biliary tract infection was confirmed in 67. Sixty-four patients completed treatment. At the end of treatment, 35...

Pseudomonas aeruginosa is a ubiquitous Gram negative opportunistic pathogen capable of causing severe nosocomial infections in humans, and tobramycin is currently used to treat P. aeruginosa associated lung infections. Quorum sensing regulates biofilm formation which allows the bacterium to result in fatal infections forcing clinicians to extensively use antibiotics to manage its infections lea...

PURPOSE To compare the efficacy of azithromycin 1.5% versus tobramycin 0.3% eyedrops on clinical ocular signs and symptoms of bacterial conjunctivitis in children and to assess the parents' satisfaction regarding the dosing regimen. PATIENTS AND METHODS An international, multicenter, randomized, investigator-masked, controlled clinical trial conducted in children (1 day to 18 years old) with ...
