[Effect of talinolol on the activity of the mixed-function oxidases of rat liver]

Experiments with male rats were performed to compare the in vitro and in vivo effects of talinolol with those of propranolol, alprenolol, practolol, proadifen (SKF 525-A) and barbital. Three in vitro model reactions (amino-phenazone N-demethylation, p-nitroanisol O-demethylation and aniline hydroxylation) as well as the hexobarbital lateral-position time served as parameters. The results obtained show that talinolol, like the other beta-receptor blockers, can inhibit polyfunctional oxidases. There were no indications of an inductive action.
