Abstract:

Five clinically health goats were injected with sulfadimethoxine and sulfadimethyloxazole in a single dose of 100 mg/kg b. wt. by intravenous route. Highest concentration levels of sulfadimethoxine and sulfadimethyloxazole in rumen were detected 1 hour following intravenous injection, then the concentration for both compounds declined at 12 and 8 hours post administration, respectively. In addition, both types of sulfonamide completely disappeared in ruminal fluid samples taken after 24 and 12 hours, respectively. The rate of acetylation for sulfadimethoxine and sulfadimethyloxazole were nearly similar and occurred to a high extent in ruminal fluid (22.95 and 23.72%, respectively). On the other hand, both tested drugs increased significantly the ruminal gas production from the first to eight hours after i.v. injection in goats. Changes in the serum enzyme activities (SGOT, SGPT and alkaline phosphatase) observed with sulfadimethoxine and sulfadimethyloxazole, and represented by a significant decrease in the activity of SGOT and SGPT level, alkaline phosphatase 4 hours sulfadimethoxine and in GOT/GPT ratio 24 and 48 hours after i.v. injection, respectively. The creatinine clearance was significantly decreased after 4 hours following the i.v. administration of sulfadimethoxine and sulfadimethyloxazole in goats.
