BACKGROUND Reducing nebulisation times for tobramycin solution for inhalation in cystic fibrosis (CF) may improve compliance. METHODS In this single-dose, open-label, two-way crossover study, 13 subjects (7 CF, 6 healthy) were randomised to receive tobramycin via eFlow rapid or LC Plus jet nebuliser. Drug deposition in the lung using gamma scintigraphic imaging, nebulisation times, pharmacoki...

The aim of this study was to determine the effectiveness of antibiotic-impregnated implants in the prevention of bone infection. We used a model of contaminated fracture in goats to evaluate four treatment groups: no treatment, hand-made tobramycin-impregnated polymethylmethacrylate beads, commercially-available tobramycin-impregnated calcium sulphate pellets and commercially-available tobramyc...

Tobramycin-resistant burn wound isolates of Klebsiella pneumoniae and Enterobacter cloacae, together with Escherichia coli K-12 transconjugants from these two strains, were examined for plasmid deoxyribonucleic acid (DNA). All the resistant strains contained a common, high-molecular-weight, covalently closed circular DNA plasmid that was absent in the tobramycin-susceptible E. coli recipient st...

An outbreak of infection caused by a strain of Staphylococcus aureus resistant to gentamicin and tobramycin and other antibiotics occurred in two wards in a hospital. Eight patients were colonized, of whom six had clinical infections. Previous administration of gentamicin appeared to predispose the patients to infection with the strain. Restriction of the use of gentamicin and tobramycin is ess...

The turbidimetric responses of a strain of Escherichia coli K12 to gentamicin and tobramycin were investigated. Both agents showed antibacterial activity below the conventionally measured minimum inhibitory concentration, but exposure to such subinhibitory concentrations of either agent generated a bacterial population which was able to grow in previously inhibitory concentrations at a rate equ...

We studied the in vivo interaction of ceftazidime and tobramycin in normal volunteers and anuric patients given each drug separately or both drugs in combination. Kinetic analysis of plasma concentration data showed minor changes in the disposition of these agents when they were given concurrently. However, the resulting clearance of both tobramycin and ceftazidime was unchanged when these drug...
