    During the application of this agent, a rapid absorption of the basic substance occurs and by hydrolysis, which is catalyzed by esterases, its transformation into dabigatran occurs.

    The agent refers to drugs that inhibit thrombin, which has an active, competitive and reversible effect. Its main effect occurs in the composition of blood plasma.

    During the cascade coagulation process, thrombin( serine protease) is converted into fibrin by fibrinogen.
