Description

Ximelagatran is an anticoagulant intended to become a replacement for warfarin by overcoming the dietary restrictions, drug interaction, and monitoring issues associated with the former. In 2006, its manufacturer AstraZeneca announced that it would not attempt to market ximelagatran after reports of hepatotoxicity (liver damage) during trials, and to discontinue its distribution in countries where the drug had been approved.

Pharmacology

Indication

For the treatment of acute deep vein thrombosis.

Pharmacodynamics
Not Available
Mechanism of action

Ximelagatran was the first member of the drug class of direct thrombin inhibitors that can be taken orally. Its effect is solely related to the inhibition of thrombin.

TargetActionsOrganism
AProthrombin
inhibitor
Humans
Absorption

Rapidly absorbed by the small intestine with an oral bioavailability of 20%.

Volume of distribution
Not Available
Protein binding
Not Available
Metabolism

Ximelagatran is a prodrug, and hence, it requires in vivo conversion to the active agent, melagatran. The activation of ximelagatran is produced in the liver and many other tissues mainly by reactions of dealkylation and dehydroxylation.

Route of elimination
Not Available
Half life

Toxicity

Hepatotoxicity (liver damage) was reported during trials.
