Description

technical field

[0001] The present invention relates to a pharmaceutical composition containing calcium dobesilate. More specifically, it is an injection and a powder injection prepared from calcium dobesilate, and the present invention also relates to the injection being used for retroocular injection. Background technique

[0002] Calcium Dobesilate is a new type of vascular protection agent, and its main pharmacological effects are: reduce its permeability, increase resistance; improve lymphatic fluid return, reduce edema; reduce blood plasma viscosity, correct albumin / The globulin ratio reduces the high aggregation of platelets, thereby preventing thrombus formation and improving the flexibility of red blood cells. This product can also inhibit the high permeability caused by vasoactive substances (histamine, 5-hydroxytryptamine, bradykinin, hyaluronidase, prostaglandin) on microvessels, reduce the damage of vascular intima, and improve the biological function of basem...
