In Italy, the drug is sold by the pharmaceutical company OM Pharma under the trade name of Doxium in capsules containing 500 mg of the active ingredient. A drug used to reduce hemorrhage in diabetic retinopathy.

Calcium dobesilate microvessel permeability may be reduced, increasing the resistance; improved lymph circulation, reduce edema; lower blood viscosity, corrected albumin/globulin ratio, reducing the high platelet aggregation, thus preventing thrombus formation, and increase red blood cell flexibility. Also inhibit vascular permeability high active substance-induced microvascular reduce intimal injury, to improve the biosynthesis of basement membrane collagen. Further, calcium besylate has a significant effect on improving the function of microcirculation. It can enhance the activity of macrovascular and microvascular endothelial nitric oxide synthase, ROS antagonizing capillary permeability changes, thereby protecting the vessel; can inhibit macrophage activating factor, macrophage decreased and thus has an anti-adhesive inflammatory effect.

Indications of Calcium Dobesilate

Agents acting to arrest the flow of blood.
