Farmakologiia i toksikologiia, 53(1), 74-77 (1990-01-01)
The data about the use of "antipyrine test" in clinical practice for studying the drug oxidation peculiarities are presented. The data characterize the main pharmacokinetic properties of antipyrine as a "metabolic marker" for quantitative estimation of the effects of inductors
F Pautet et al.
Pathologie-biologie, 33(7), 777-780 (1985-09-01)
Antipyrine is widely used as a model compound to assess the hepatic metabolism in man. This drug is extensively metabolized by the hepatic microsomal drug-oxidizing system, into three main metabolites and six minor compounds of the phase I. The metabolite
