How dabigatran etexilate capsules (Pradaxa) works

Dabigatran etexilate (Pradaxa)’s mechanism of action is based on its properties as a direct thrombin inhibitor. Thrombin is a key enzyme in the blood coagulation process and is responsible for catalyzing the formation of fibrin, thereby promoting blood coagulation. Dabigatran etexilate achieves an anticoagulant effect by directly inhibiting the activity of thrombin and preventing the coagulation cascade reaction from proceeding.

The specific mechanism of action includes the following aspects:

1.Directly inhibits thrombin activity: Dabigatran etexilate combines with thrombin to form a stable complex, thereby preventing thrombin activity. This direct inhibitory effect is independent of other coagulation factors in the coagulation cascade, making it relatively specific.

2.Blocking fibrin formation: Thrombin catalyzes the conversion of fibrinogen into fibrin, thereby promoting blood clot formation. The inhibitory effect of dabigatran etexilate blocks this step, effectively reducing thrombus formation.

3.Reversible effect: The effect of dabigatran etexilate is reversible, which means that its anticoagulant effect can be quickly reversed by administering a reversal agent if necessary. This increases management flexibility in emergency situations, particularly when surgery is required or bleeding events are managed.

4.Oral administration: Dabigatran etexilate is an oral anticoagulant drug. Compared with traditional injectable anticoagulant drugs, it improves the convenience of medication for patients.

Dabigatran etexilate capsules have been launched in China and have been included in medical insurance. Patients can purchase them domestically. Please consult the local hospital pharmacy for specific prices. The main foreign drug is the original drug of dabigatran etexilate capsules. The cheaper one is the Turkish version of the original drug from Germany. The price of 110mg*60 capsules is about three to four hundred, and the ingredients and efficacy are consistent with the original drug on the domestic market.
