Fat-soluble drug submicron capsule glucose injection and preparation method thereof

Abstract

The invention discloses a fat-soluble drug submicron capsule glucose injection and a preparation method thereof. The invention is characterized in that the capsule material comprises the following components in parts by weight: 15-45 parts of sodium alginate, 2.5-9 parts of poloxamer 188, 1.5-5 parts of silk fibroin, 0.5-3 parts of polyvinyl alcohol and 0.2-3 parts of polyethylene glycol. The preparation method comprises the following steps of: sequentially adding the poloxamer, a silk fibroin aqueous solution, a polyvinyl alcohol aqueous solution, the polyethylene glycol and glucose into a sodium alginate aqueous solution at intervals under stirring, and finally dropwise adding a corresponding fat-soluble drug; adopting an ultrasonic and shearing treatment mode; and finally, carrying outfiltration with a 450nm membrane and damp-heat sterilization to obtain the submicron capsule glucose injection. The preparation process of the submicron capsule glucose injection provided by the invention is simple and economic, the particle size of submicron capsules is controllable and uniform, and the biological safety is high.

Description

technical field [0001] The invention belongs to the medical technical field of fat-soluble drug preparations, and in particular relates to a fat-soluble drug submicrocapsule glucose injection and a preparation method thereof. Background technique [0002] Fat-soluble drugs have significant pharmacological activity, and the active ingredients are prone to oxidative deterioration to affect drug properties, and their solubility in the human body environment is low, making it difficult to reach the effective concentration of the drug. Therefore, solubilizers are commonly used clinically to improve the stability and solubility of fat-soluble drugs, and at the same time achieve targeting, improve the bioavailability of drugs, and reduce toxic and side effects. [0003] When the bilayer membrane liposome is used as a water-soluble drug delivery system, there is still a problem of thermodynamic instability, but when it is applied to a fat-soluble drug, it is a single-layer membrane,...
