Oxytetracycline is a tetracycline antibiotic produced by Streptomyces rimosus. Possesses a wide spectrum of antibacterial action, is active against many gram-positive and gram-negative microorganisms, incl. Escherichia, Salmonella, Staphylococcus, Streptococcus, Rickettsia, and some types of Mycoplasma; does not act on Pseudomonas aeruginosa, Proteus, most fungi, and small viruses. The mechanism of the antibacterial action of oxytetracycline is based on the suppression of protein synthesis of the microbial cell (blockade of ribosome function) and blockade of RNA synthesis.
