[Computer-assisted determination of the pharmacokinetic parameters of Solupront after intrauterine administration in cattle].

The drug "Solupront" a sulfonamide was clinical tested in healthy heifers and cows with endometritis, retentio secundinarum etc. The test-results were evaluated with the computer-program "Phakimo". The pharmacokinetic parameters show that there are similar relationships between the extravasal and the intravasal application of this osmochemotherapeutic. A retard of absorption is shown in dioestrus and in prooestrus. If there are pathological signs in uterus, the rate of absorption of the drug is higher and the excretion via urine is more quickly, too. The effect of the sulfonamide in the drug "Solupront" is impaired after application in the uterus in order of the quick absorption, of distribution and excretion and also in order of dilution by lochia and by interaction with p-aminobenzoic acid.
