Problems solved by technology

In addition, the traditional Chinese medicine injection itself still has the problem that the pH value of the solution drops significantly during the sterilization and storage process, and polysorbate 80 (Tween 80) is prone to rancidity, which accelerates the drop of the pH value of the liquid medicine.

Abstract

The invention discloses a pharmaceutical composition capable of improving the safety of a compound rhizoma polygonati injection. The pharmaceutical composition is characterized in that the pharmaceutical composition is an injection pharmaceutical composition prepared from a rhizoma polygonati extract, a bighead atractylodes rhizome extract, a platycodon root extract and glycerin polyoxyethylene ether hydroxystearate, wherein each 100ml solution contains 15 to 45g of rhizoma polygonati extract prepared from rhizoma polygonati, 10 to 10g of bighead atractylodes rhizome extract prepared from bighead atractylodes rhizome and 5 to 15g of platycodon root extract prepared from platycodon root, and the dosage ratio of the rhizoma polygonati to the bighead atractylodes rhizome to the platycodon root is 3 to 2 to 1. According to the pharmaceutical composition disclosed by the invention, a cosolvent which has better safety and more obvious solubilization effect is adopted to substitute a cosolvent polysorbate 80, which has potential safety hazards and affects the product quality, in the compound rhizoma polygonati injection, and the glycerin polyoxyethylene ether hydroxystearate has higher safety and lower dosage than those of the polysorbate 80, such that the probability and risk of adverse reactions of the pharmaceutical composition are reduced, and the safety of the clinical medication is improved.

Description

technical field [0001] The invention belongs to the technical field of medicines, and in particular relates to a pharmaceutical composition for improving the safety of Compound Polygonatum Injection. Background technique [0002] The standard of Compound Rhizoma Polygonatum Injection is recorded in the drug standard issued by the Ministry of Health (preparation of traditional Chinese medicine). It has the effects of promoting blood circulation and promoting menstrual flow, dispelling blood stasis and relieving pain. It is clinically used to treat dysmenorrhea, amenorrhea, injury from tumbling, rheumatic arthralgia, etc. [0003] Compound Polygonatum Injection has been widely used clinically in my country for many years, and its clinical efficacy has been well received by both doctors and patients. However, in recent years, reports of adverse reactions in the clinical application of traditional Chinese medicine injections have become more and more serious, which has affecte...
