Abstract

The invention discloses a pharmaceutical composition for improving the safety of compound angelica injection. The pharmaceutical composition is a pharmaceutical composition for injection mainly made of angelica extract, astragalus extract, notoginseng extract and methyl methacrylate. The present invention adopts the co-solvent with better safety and more obvious solubilizing effect to replace the co-solvent phenoxyethanol which has potential safety hazards and affects product quality in the compound angelica injection, and the safety of methyl methacrylate is higher than that of phenoxyethanol. The dosage is lower, reducing the probability and risk of adverse drug reactions, and improving 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 angelica injection. Background technique [0002] The standard of compound angelica injection is recorded in the drug standard issued by the Ministry of Health (preparation of traditional Chinese medicine), and the raw materials are angelica, astragalus, and notoginseng, 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 Angelica 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 app...
