Pharmacodynamics Tetracyclines broad-spectrum antibiotics. Takes strong effect on staphylococcus, hemolytic streptococcus, anthrax, clostridium tetanus, clostridium and other gram-positive bacteria, but not strong as β-lactam. Sensitive to Escherichia coli, salmonella and pasteurella, brucella and other gram negative bacteria, but not as good as the aminoglycosides and amide alcohol antibiotics. The product is inhibited to rickettsia, chlamydia, mycoplasma, spirochetes, actinomycetes and some protozoa.
Pharmacokinetics The apparent volume of distribution of oxytetracycline in small animal is about 2.1L/kg, horse 1.4L/kg, cow 0.8L/kg. Oxytetracycline mainly excreted in prototype by the glomerular filtration. When there is renal dysfunction, excretion reduced and half-life extended. The half-life of oxytetracycline is 10.5 hours for horses, 4.3 to 9.7 hours for cattle, 6.7 hours for pigs, and 4 to 6 hours for dogs and cats.
Drug Interactions
①Renal damage increased when administered together with strong diuretics such as furosemide. ②It is a rapid antibacterial agent, which can interfere with the bactericidal action of penicillin on the reproduction of bacteria, and should avoid administerring together with penicillin drugs. ③It can form insoluble complexes and reduce the absorption of drugs when administer with the calcium salt, iron salt, metal ion calcium, magnesium, aluminum, bismuth, iron and other drugs (including Chinese herbal medicine).
Applications
