Description

People suffering from venous thrombosis or varicose veins are often prescribed funds designed to reduce blood clotting and thereby resist thrombosis. Among the variety of medicines of this group, its effectiveness is the drug Coumadin. Instructions for use will tell you about its pharmacological action and the recommended doses of such medication.

Structure of the preparation

The drug is produced in the form of flat-cylindrical tablets, in each of which there is 2.5 mg of active substance – sodium warfarin. Among the auxiliary components present in the drug, it is worth highlighting: lactose monohydrate, povidone K25, magnesium stearate and potato starch.

Pharmacological effect

The drug Coumadin is an anticoagulant. In a clear language, this drug reduces blood coagulability. This is due to the ability of the drug to reduce the activity of vitamin K, which has a direct effect on blood coagulability.

From the above, it can be understood that Coumadin is an indirect action coagulant, because it does not directly affect the coagulability of the blood. That is why the effect of the use of the drug develops slowly. It should be noted that indirect coagulants are prescribed in cases where a prolonged reduction in coagulability is necessary, as well as to prevent the appearance of repeated thrombi. The effect of using Coumadin appears on the 4th day of regular medication, and it disappears after a similar period of time after taking the last pill.

Indications for use

The drug Coumadin is prescribed in the following pathological conditions:

Dosing regimen

The preparation is produced in tablets of 5, 3 and 2.5 mg. The optimal dosage should be selected by a specialist, taking into account the patient’s condition and the existing disease.
Take Coumadin tablets once or twice a day, washing them with water. More precise dosage and duration of the medication will be indicated by the attending physician. In most cases, the dosage is from 2 to 10 mg. The course is long and usually is 6-12 months. In the case of a surgical procedure, which increases the risk of thromboembolic complications, the medication is started 3 days before the operation.
