Abstract

The present invention relates to an adenosine cyclophosphate injection and a preparing process thereof. According to the invention, acidum citricum is added into a magnetic stirring pot. Injection water with confect amount of 50% is added and dissolved. The adenosine cyclophosphate and meglumine are added into the solution. The obtained solution is mixed to be dissolved. The 0.02% of activated carbon with needle use in volume is added. The mixture is mixed for 30 minutes. The mixture is preliminarily filtered fro removing carbon. The adenosine cyclophosphate injection is prepared for standby. The injection water is added to the total amount. The pH value is adjusted to 6.0-6.5 by sodium hydroxide solution with concentration of 10%. The colorless transparent injection is prepared. The adenosine cyclophosphate injection of the invention not only has the advantages of straight function, high speed, etc., but also has the advantages of little adverse effect, normal temperature transportation and normal preserving, thereby increasing the stability and safety of the product.

Description

technical field [0001] The invention relates to a preparation method of chemical medicines, in particular to an adenosine cyclic monophosphate meglumine injection and a preparation process thereof. Background technique [0002] Since meglumine cyclic adenosine is slightly soluble in water, adding meglumine to meglumine cyclic adenosine can increase its solubility. However, in the solution of meglumine cyclic adenosine Phosphate meglumine will gradually precipitate out, causing the liquid to deteriorate and become turbid. If the change is small, it will be difficult to detect. If it is given to the patient, it will cause serious adverse reactions to the patient, thereby affecting the curative effect of the drug, and at the same time affecting the safety of the drug. Therefore, in order to improve the safety of medication and reduce the occurrence of adverse drug reactions, many manufacturers make meglumine cyclic adenosine monophosphate into freeze-dried preparations for eas...
