[Comparative enantioselectivity of the disposition of two non-steroidal anti-inflammatory agents, ketoprofen and carprofen, in man and animals].

After the administration of racemic ketoprofen and carprofen to man, both enantiomers of each compound exhibit similar plasma profiles. This contrasts with the rat where the active S(+) enantiomer is predominant. For carprofen, regardless of the route of administration, the R(-) enantiomer is predominant in the plasma of all investigated animal species.

The non-human primate: a possible model for human genetically determined polymorphisms in oxidative drug metabolism.

Genetic polymorphisms of drug oxidation are major determinants of interindividual variations in drug response and toxicity. Many animal models, including rats, have been used for clinical investigations of pharmacogenetics. However, because of large interspecies differences, these data are difficult to extrapolate to humans.

Antifilarial activity of CGP 20,376 in chimpanzees (Pan t. troglodytes) naturally infected with Dipetalonema vanhoofi.

CGP 20,376, a benzthiazole and new antifilarial agent, was investigated at CIRMF in eight wild born chimpanzees naturally infected with Dipetalonema vanhoofi. Single oral doses (3.75, 7.
