warfarin

 [wor´fah-rin]
a synthetic coumarinanticoagulant, usually used as the sodium salt; administered orally or intravenously. It is also used as a rodenticide, causing fatal hemorrhaging in any mammal that consumes a sufficient dose, including humans.

war·fa·rin

(wōr'fă-rin),
An anticoagulant with the same actions as dicumarol; also used as a rodenticide; also available as the potassium salt, with the same actions and uses.

warfarin

(wôr′fər-ĭn)
n.
A white crystalline compound, C19H16O4, that inhibits production of prothrombin and is used in the form of its sodium salt as an anticoagulant drug and as a rodenticide.

warfarin

An anticoagulant that inhibits synthesis of liver-dependent coagulation factors (the prothrombin complex, factors II, VII, IX and X), which are formed by gamma-carboxylation of precursor proteins.
 
Indications
Prevention of uncomplicated distal DVT, prophylaxis and prevention of thromboembolism, post-acute myocardial infarction.

Monitoring
Warfarin therapy is monitored by serial evaluation of PT–2-3-fold > normal 12–16 seconds; its activity is increased by phenylbutazone, clofibrate (by outcompeting with warfarin for plasma-protein binding sites and decreased by barbiturates, which stimulate hepatic metabolism).

Anticoagulant with same actions as dicumarol.

warfarin

a coumarin compound used as an anticoagulant in humans and as a rodenticide, with serious toxicity implications for all species. It is readily absorbed from the intestinal tract and acts to inhibit the reduction of oxidized vitamin K, resulting in a depletion of active vitamin K that is required for carboxylation of coagulation factors VII, IX, X and II.
Accidental poisoning in all species causes massive, spontaneous hemorrhage and death due to anemia. Less severe cases often show pulmonary hemorrhage. In pigs it is the legs that are affected preferentially and in dogs hemorrhage into the anterior mediastinum and lungs is common. Vitamin K is the specific antidote.

Patient discussion about warfarin

Q. how medications effect me side effects warfarin,s effect what does I and R mean i have my I and R each week, what is it,s function..........

A. It depends what the heart condition is but probably not. Not being on warfarin may increase your risk of stroke. Most importantly you need to address this wuestion with the doctor that prescribe the warfarin to you.
