Abstract

The invention relates to the technical field of medicines, in particular to an arbidol hydrochloride injection emulsion and a preparation method thereof. The arbidol hydrochloride injection emulsion comprises the following components: arbidol hydrochloride, an emulsifier, a co-emulsifier, oil for injection, an isoosmotic adjusting agent, a pH adjusting agent, an antioxidant and water for injection, wherein the emulsifier is soybean lecithin and Tween 80, and the co-emulsifier is Arabic gum and n-propyl alcohol. According to the preparation method of the arbidol hydrochloride injection emulsion provided by the invention, a high-pressure homogenization process is adopted, and the drug is entrapped in the emulsion droplets, so that the drug loading capacity of the preparation is improved, the solubility and bioavailability of arbidol hydrochloride are improved, the administration frequency is reduced, the toxic and side effects and irritation are reduced, and the preparation is high in stability. The problem that the medicine is easy to separate out in the storage and use processes of the conventional injection emulsion is solved; and meanwhile, administration is convenient, effect taking is fast, the preparation technology is simple, and the preparation method can be used for industrial large-scale production.

Description

technical field [0001] The invention relates to the technical field of medicine, in particular to an arbidol hydrochloride injection emulsion and a preparation method thereof. Background technique [0002] Arbidol hydrochloride (also known as Arbidol hydrochloride, Arbidol), its chemical name is: 6-bromo-4-(dimethylaminomethyl)-5-hydroxyl-1-methyl-2-(phenylthio Methyl)-1H-indole-3-carboxylic acid ethyl ester hydrochloride is an antiviral drug developed by the former Soviet Medicinal Chemistry Research Center as a treatment for A and B influenza viruses and other acute respiratory virus infections Preventive and therapeutic drugs can significantly improve the clinical symptoms of patients. [0003] Arbidol hydrochloride is a drug that is insoluble in water. Arbidol hydrochloride injection prepared by conventional preparation methods has low bioavailability due to its low water solubility and short half-life. And during use, the drug is prone to precipitation, and the drug s...
