Gentamycin (as sulphate) 100 mg


Gentamycin is an antibiotic belonging to the group of amino-glycosides. It has bactericidal activity against Gram-positive and Gram-negative bacteria (including: Pseudomonas spp., Klebsiella spp., Enterobacter spp., Serratia spp., E. coli, Proteus spp., Salmonella spp., Staphylococci). Furthermore it is active against Campylobacter fetus subsp. jejuni and Treponema hyodysenteriae. Gentamycin may be active against bacteria which are resistant to other amino-glycoside antibiotics (like neomycin, streptomycin, and kanamycin). After intramuscular administration, within 30 – 60 minutes maximum serum concentrations are obtained. Gentamycin is excreted mainly by the kidneys, resulting in high concentrations of the active compound in the urine.


Gentaject 10% Inj. is effective in the treatment of infections caused by micro-organisms, susceptible to gentamycin, occurring in urogenital, respiratory, skin, tissue, and gastrointestinal infections.
