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.
