title: Oxytetracycline plasma concentrations in sheep after the administration of a polyvinylpyrrolidone formulation.
abstract: A polyvinylpyrrolidone formulation of oxytetracycline was injected intramuscularly into 5 sheep at 2 different dosages of 10 mg and 20 mg/kg body mass respectively. Plasma levels were determined. The higher dosage not only attained a higher peak value, but the concentration at 12 hours was 0.5 micrograms/ml. At the lower dosage rate a level of 0,63 micrograms/ml was recorded 32 hours after administration when that of the higher dosage rate was 1,5 micrograms/ml.
