Abstract

The invention discloses an ozagrel sodium medicinal composition for injection. Ozagrel sodium injection consists of ozagrel sodium, sodium citrate and calcium disodium edetate, wherein each piece of injection contains 40-100 mg of ozagrel sodium, 4-10 mg of sodium citrate and 0.02-0.05 mg of calcium disodium edentate. A preparation method of the composition comprises the following steps of: adding a prescription dose of sodium citrate and calcium disodium edentate into a prescription dose of 90 percent injection water at the temperature of 55-65 DEG C and stirring to dissolve; adding a prescription dose of ozagrel sodium and stirring until the ozagrel sodium is fully dissolved; measuring an initial pH value, and adjusting the pH value to be within a range of 7.5-9.5 by using 4 percent sodium hydroxide solution and 10 percent sodium citrate solution according to the initial pH value; adding medicinal carbon and stirring; performing extraction filtration, replenishing injection water to full amount and uniformly mixing; performing fine filtration; canning; sterilizing; performing light inspection; and warehousing to obtain the ozagrel sodium injection. The ozagrel sodium medicinal composition has high light stability, clarity and stability and does not produce crystals, and has the more obvious advantages of improving the product yield, reducing the cost, realizing industrialization and guaranteeing better application to clinical use.

Description

technical field [0001] The invention relates to medicines in the field of medicine, in particular to an ozagrel sodium pharmaceutical composition for injection that is stable to light, does not produce crystals, and has good stability and a preparation method thereof. Background technique [0002] Ischemic cerebrovascular disease (ischemic stroke) is caused by the temporary or permanent reduction of blood flow in an arterial blood supply area due to embolism or hemorrhage. Its pathological process involves complex temporal and spatial cascade reactions, and its mechanism is related to Ca + Overload, free radical damage and other factors are related. Ozagrel Sodium (Ozagrel Sodium) has a specific inhibitory effect on thromboxane A synthetase, and its pharmacological effects mainly include: anti-platelet aggregation, dilating blood vessels. In addition, ozagrel also has the effect of inhibiting lipid peroxidation, can reduce the generation of free radicals, can directly scave...
