GENTA-DOX 20/20 WSP is a combination containing gentamicin and doxycycline. Gentamycin belongs to the group of amino-glycoside antibiotics and has bactericidal action mainly against Gram-negative bacteria E. coli, Klebsiella, Pasteurella and Salmonella spp. Doxycycline is a tetracycline antibiotic and acts  bacteriostatic against a large number of Gram-positive and Gram-negative bacteria such as Campylobacter, E. coli, Haemophilus, Pasteurella, Salmonella, Staphylococcus and Streptococcus spp. Doxycycline is also active against Chlamydia, Mycoplasma and Rickettsia spp. It also acts against Mycoplasma spp., Rickettsiae and Chlamydia spp. The action of doxycycline is based on inhibition of bacterial protein synthesis. Gentamycin is not absorbed from the gastrointestinal tract and therefore acts locally. Doxycycline has a great affinity to lung tissues; therefore, it is recommended especially for respiratory tract infections. This combination provides an intensive antibacterial effect in the gastrointestinal tract and a rapid and intensive systemic effect after absorption.



GENTA-DOX 20/20 WSP is indicated for the treatment of infections caused by micro-organisms susceptible to gentamycin and/or doxycycline. GENTA-DOX 20/20 WSP is indicated for the treatment of gastrointestinal infections and respiratory tract infections in calves, lamb, pigs and poultry. GENTA-DOX 20/20 WSP is a potent antibacterial product and useful in most infective diseases in the targeted animals.
