Once-daily tobramycin therapy in lower respiratory tract infections.

In a multicenter Italian study of 104 adult patients with severe bacterial lower respiratory tract infections, the safety and efficacy of a regimen of high dose, once-daily tobramycin alone or in combination with antipseudomonas betalactams was assessed. The overall bacteriological response was an elimination of the original pathogen in 70% of the patients while the overall clinical response mirrored the bacteriological results with a successful clinical outcome in 78% of patients. Adverse experiences were, in general, few and mild without oto- or nephrotoxicity. The once-daily, high dose regimen of tobramycin proved to be a safe and efficacious therapy for severe lower respiratory tract infections in adult patients.
