Oxytetracycline is a bacteriostatic antibiotic. Oxytetracycline is represented in the drug as a complex with magnesium which stipulates its long lasting (prolonged)
effect. Oxytetracycline as a drug component inhibits synthesis of bacterial protein by blocking bind of amino acid-tRNA with 30S ribosome subunit.
Antibiotic spectrum covers most gram-positive and gramnegative bacteria, namely Streptococcus, Staphylococcus, Corynebacterium, Clostridium, Erysipelothrix, Pasteurella, Fusobakterium, Salmonella, Pseudomonade, Haemophilus, Actinobacterium, Shigella, Escherichia, chlamydia, rickettsia, spirochetes and mycoplasma.
During intramuscular injection antibiotic is rapidly reabsorbed from the injection point and reaches maximum concentration in the tissue approximately 30-50 minutes after injection. Therapeutic effect of this antibiotic in tissues retains for at least 20 hours. It is eliminated primarily with urine and with milk in lactating animals.
It penetrates into all animal organs and tissues overcoming placental barrier. It is eliminated primarily with urine, bile and with milk as well in lactating animals.
