Abstract
The invention relates to a vinpocetine injection and a preparation method thereof. The vinpocetine injection comprises 10 to 20 parts of vinpocetine, 7 to 15 parts of tartaric acid and 2000 parts of water. The preparation method of the vinpocetine injection comprises the following steps of 1, taking 80% of water for injection, carrying out filtration deoxygenation, heating to a temperature of 40 to 50 DEG C, adding tartaric acid into the heated water for injection, and stirring until complete dissolution, 2, adding vinpocetine into the solution obtained by the step 1, stirring until complete dissolution, supplying enough water for injection to the mixed solution, and carrying out stirring adsorption by 0.3% of active carbon, and 3, carrying out sterilization at a temperature of 121 DEG C for 15 minutes and carrying out nitrogen-filling loading. Utilization of tartaric acid in the components of the vinpocetine injection is conducive to dissolution of alkaline vinpocetine and can effectively inhibit the production of insoluble particles. A contrast experiment proves that through the preparation method, drug composition stability is improved. The production of insoluble particles shows that products are unstable due to prolonging of a storage period. The vinpocetine injection adopting tartaric acid as a cosolvent is stable and can produce a small amount of insoluble particles in a long time and thus the safety of the vinpocetine injection in use is ensured.
Description
Technical field
The invention belongs to field of medicine preparations, relate to a kind of Vinpocetine injection, meanwhile, the invention still further relates to a kind of preparation method of this Vinpocetine injection.
Background technology
Vinpocetine belongs to cerebral vasodilator, can suppress phosphodiesterase activity, increase the effect of the courier c-GMP of vascular smooth muscle relaxation, optionally increase cerebral blood flow, can also suppress platelet aggregation in addition, reduce human blood viscosity, strengthen erythrocyte deformabiliy, improve blood fluidity and microcirculation, promote cerebral tissue ingestion of glucose, increase brain oxygen consumption, improve brain metabolism.
In Vinpocetine injection long term storage process, easily produce insoluble particulates, affect the use safety of medicine, cause two classes to endanger, the insoluble granule filter that results in blockage while entering patient's vein obstruction vein blood vessel and intravenously administrable.
Summary of the invention
One of object of the present invention is to provide a kind of stable Vinpocetine injection.
To achieve these goals, technical program of the present invention lies in adopting a kind of Vinpocetine injection, consist of: vinpocetine 10-20 part, tartaric acid 7-15 part, 2000 parts, water.
Described water is water for injection.
In addition, the present invention also aims to provide a kind of preparation method of Vinpocetine injection safely and effectively.
To achieve these goals, the preparation method of Vinpocetine injection of the present invention, its step is as follows:
(1) get 80% water for injection and filter deoxygenation, be heated to 40-50 ℃, add tartaric acid, stir completely and dissolve;
(2) will in the resulting solution of step (1), add vinpocetine, stir, dissolve completely, supply water for injection, the active carbon stirring and adsorbing with 0.3%;
(3), at the temperature of 121 ℃, sterilizing 15min, fills nitrogen fill.
In each component of the present invention, tartaricly add the dissolving that not only contributes to alkaline vinpocetine, and can effectively stop the generation of particulate matter.Through Experimental Comparison, adopt technical solution of the present invention can strengthen the stability of pharmaceutical composition, the formation of insoluble granule has shown the product unstability that extends storage period and cause, with other acids contrasts, tartaric acid is more stable as the Vinpocetine injection of cosolvent, the insoluble granule quantity producing within the longer time still less, more can be guaranteed the safety that injection is used.
In addition, preparation method of the present invention can be used 121 ℃ of 15min sterilizings, illustrates that this prescription is stable, can be applied to suitability for industrialized production.Than original prescription, can adopt 121 ℃, the excessive sterilizing of 15min, guarantees the aseptic level of medicine.
