Ethamsylate (Dicynene/Dicynone) is a haemostatic drug.[1][2]

It is believed to work by increasing capillary endothelial resistance and promoting platelet adhesion.

It also inhibits biosynthesis and action of those prostaglandins which cause platelet disaggregation, vasodilation and increased capillary permeability.[3]
