Influence of induced disease states on the disposition kinetic of imidocarb in dogs.

Disposition kinetics of imidocarb, an antiprotozoan drug, was studied in normal and febrile dogs. Fever was induced using E. coli endotoxin and Trypanosama evansi. The concentration of imidocarb in body fluids were measured by spectrophotometry. The disposition kinetics of imidocarb in normal and fe...
