Etamsylate.......................250 mg
Etamsylate is a synthetic antihemorrhagic and angioprotective drug acting on the first step of hemostasis (endothelium - platelet interaction). By improving platelet adhesiveness and restoring capillary resistance. It reduces the bleeding time and blood losses.
Etamsylate has no vasoconstrictor action, it does not influence fibrinolysis nor modify the plasma coagulation factors.

When given post-operatively, etamsylate is slowly absorbed from the gastrointestinal tract. After oral administration of 500 mg etamsylate maximum plasma level, i.e. 15 µg/ml, is reached at 4 hours, but bioavailability is unknown. The binding rate to plasma proteins is about 95%. Plasma half-life is about 3.7 hours. About 72% of the administered dose is excreted in the first 24 hours in urine, the molecule is excreted unchanged.
Etamsylate crosses the placental barrier. Maternal and cord blood contains similar concentrations of etamsylate. It is not known if etamsylate is excreted in the maternal milk.
It is not known if the pharmacokinetic properties of etamsylate are modified in patients suffering from renal and/or hepatic function disorders.
After IV administration of 500 mg etamsylate (2 ampoules), the maximum plasma level, i.e. 50 µg/ml, is reached at 10 minuts. The plasma half-life is around 1.9 hours. About 85% of the administered dose are excrete in the first 24 hours urine.
