pharmachologic effect

Tobramycin is an antibiotic that acts on a wide spectrum of pathogens and belongs to the group of aminoglycosides. In a low concentration, bacteriostatic action appears (inhibits the 30S subunit of ribosomes and stops the synthesis of the protein), bactericidal action is more pronounced in high concentrations (changes the permeability of cell membranes, causing cytolysis).
Antibacterial activity is high in relation to: Staphylococcus spp. (including Staphylococcus epidermidis, Staphylococcus aureus and their penicillinase-producing, coagulase-negative and coagulase-positive strains), Streptococcus spp. (including beta-hemolytic strains of group "A", some non-hemolytic strains, Streptococcus pneumoniae), Enterococcus spp., Escherichia coli, Proteus spp. (including Proteus vulgaris, Proteus mirabilis, indolpositive and indolegative strains), Serratia spp., Enterobacter spp. (Enterobacter aerogenes), Providencia spp., Citrobacter spp., Haemophilus aegyptius, Morganella morganii, Acinetobacter calcoaceticus (Herellea vaginacola), Moraxella lacunata, to some representatives of Neisseria spp. (including Neisseria gonorrhoeae).
Tobramycin in the spectrum of action is similar to gentamycin, but the former is more active with respect to gentamycin-resistant strains and can be used as a drug of choice for low efficacy of neomycin-containing eye drops.
Tobramycin is highly effective against infections caused by Pseudomonas aeruginosa.
Tobramycin has a low efficacy against the majority of streptococcal strains belonging to group D.
