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 for improving the safety of compound Dinggongteng injection, the pharmaceutical composition is mainly composed of Dinggongteng extract, rhubarb extract, hair holly extract and hexafluorobutyl methacrylate for injection pharmaceutical composition. The present invention adopts the co-solvent with better safety and more obvious solubilizing effect to replace the co-solvent polysorbate 80, which has potential safety hazards and affects product quality in the compound Dinggongteng injection, and the safety of hexafluorobutyl methacrylate is higher than that of polysorbate The ester 80 is high and the dosage is lower, which reduces the probability and risk of adverse drug reactions and improves the safety of clinical medication.

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 Dinggongteng injection. Background technique [0002] The standard of compound Dinggongteng injection is recorded in the drug standard issued by the Ministry of Health (Chinese medicine prescription preparation), and the raw materials are Dinggongteng, rhubarb and Maodongqing, which belong to traditional Chinese medicine injection. 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 Dinggongteng 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 cl...
