| Popis: | Following intravenous administration of an oxytetracycline-HC1 and an oxytetracycline-dihydrate formulation to dairy cows, no statistical difference could be found between the pharmacokinetic parameters, derived from the three-compartment model, of these preparations. Urinary recovery was continued for a period of 72 h following intravenous or intramuscular OTC administration. The recovery of OTC in the urine in the 72-h period was in the range of 73% to 96% of the available dose administered. The renal OTC clearance, the renal creatinine clearance, the urinary flow, and the interrelationships of these were determined on the basis of urine and plasma data. The mean OTC renal clearance ranged from 482 to 1050 ml/min and the creatinine clearance from 651 to 1304 ml/min. The OTC and creatinine clearances were significantly correlated to the urine flow up to 30 ml/min. The total body clearance and renal clearance values were of the same order of magnitude, and along with the urine recovery data they provided evidence of predominantly renal route of OTC elimination in dairy cows. The renal OTC elimination is the net result of mainly glomerular filtration, partly tubular secretion, minus reabsorption in the urogenital tract. |
