Tobramycin Sulfate: A Summary of Worldwide Experience from Clinical Trials

Abstract

Tobramycin sulfate, a new bactericidal amino glycoside antibiotic, has been evaluated in 3,506 patients. Its in vitro activity is similar to that of other aminoglycoside antibiotics, except that it is more active against Pseudomonas aeruginosa. Clinical studies have shown that tobramycin sulfate is well tolerated and effective in the treatment of the infections listed below when they are caused by susceptible gramnegative organisms and by staphylococci: infections of the respiratory tract (including cystic fibrosis), central nervous system, skin, soft tissue, and bone (including burns); urinary tract and intraabdominal infections; and septicemia. The overall response was satisfactory in >86% of the patients. Drug-related adverse effects were reported in 3.9% of the patients, and included reactions in the nervous system in 0.6% and in the kidney in 1.5%.
