Background:

Phenprocoumon is a coumarin derivative that acts as a long acting oral anticoagulant and an antagonist of vitamin K.

After a single i.v.-dose of phenprocoumon (0.355 mg/kg) the anticoagulant effect obtained is greater in older than in younger rats. There are no differences between younger and older rats in the rate of elimination, volume of distribution and in the free fraction and free concentration values of phenprocoumon in plasma and liver. After i.v.-injection of 64.3 μg/kg [3H]vitamin K1 and different doses of phenprocoumon (0.02 to 3 mg/kg) the [3H]vitamin K1 concentration in the liver decreases and the [3H] vitamin K1-2, 3-epoxide concentration increases dependent on the dose and the liver concentration of phenprocoumon. These changes are more pronounced in the older than in the younger rats[2].
