A pharmacokinetic and bioavailability study of sulfadiazine combined with trimethoprim (sulfadiazine/trimethoprim) was carried out in fifteen healthy young ostriches after intravenous (i.v.), intramuscular (i.m.) and oral administration at a total dose of 30 mg/kg body weight (bw) (25 and 5 mg/kg bw of sulfadiazine and trimethoprim, respectively). The study followed a single dose, three periods...

Cadmium has been associated with a number of adverse health effects but the impact of those effects on the pharmacokinetics of different drugs has not been investigated. Therefore, the pharmacokinetics of theophylline and ciprofloxacin were studied in cadmium-exposed and control rats (72 rats) following i.p. (6.5mg/kg) and p.o. (10mg/kg) administration, respectively. The third-generation offspr...
