Abstract

The invention belongs to the technical field of medicine, and discloses a drug composition of meclofenoxate hydrochloride and polyethylene glycol and a preparation method thereof. The weight ratio of the meclofenoxate hydrochloride and the polyethylene glycol is 1:0.002-0.1. The invention solves the problems that the meclofenoxate hydrochloride is easily hydrolyzed when meeting water and instably stored in the prior art. The drug composition has stable property and convenient storage, and improves the safety of clinical medication.

Description

1. Technical field [0001] The invention belongs to the technical field of medicine, and in particular relates to a pharmaceutical composition of meclofenac hydrochloride and polyethylene glycol and a preparation method thereof. 2. Background technology [0002] Meclofenoxate Hydrochloride is a central nervous system stimulant that has been used for many years. It was synthesized by the French Academy of Sciences in 1957. Its chemical name is 2-(dimethylamino)ethyl p-chlorophenoxyacetate hydrochloride Salt. It can promote the oxidation-reduction metabolism of brain cells, increase the utilization of carbohydrates, and have an excitatory effect on patients with central nervous system depression. It is used to treat traumatic coma, alcoholism, neonatal hypoxia, and children's enuresis, with definite curative effect and good safety. [0003] Because meclofenoxate hydrochloride is extremely unstable in aqueous solution, the dosage forms for intravenous injection on the market a...
