Pharmacogenetic differences between warfarin, acenocoumarol and phenprocoumon.

Coumarin oral anticoagulant drugs have proven to be effective for the prevention of thromboembolic events. World-wide, warfarin is the most prescribed drug. In Europe, acenocoumarol and phenprocoumon are also administered. Yet it has been proven that variant alleles of the VKORC1 and CYP2C9 genotypes influence the pharmacokinetics and pharmacodynamics of these drugs. The combination of these tw...

Use of different tissue thromboplastins in the control of anticoagulant-therapy.

As anticoagulant therapy has become more widespread and a greater knowledge has been accumulated regarding the mode of action of coumarin derivatives, problems arising from the use of different thromboplastin preparations have been subjected to greater scrutiny. This paper presents an evaluation of the dependability and significance of different types of tissue thromboplastin in the determinati...
