Abstract

The invention relates to the field of pharmaceutical preparations, and in particular, relates to a polydatin pharmaceutical composition containing no organic solvent and a preparation method thereof.The polydatin pharmaceutical composition comprises polydatin, a solubilizing agent and a solvent. The solubilizing agent is polyethylene glycol dodecyl hydroxy stearate, and the solvent is water for injection or a pH buffer solution or a sodium chloride solution or a glucose solution. According to the polydatin pharmaceutical composition containing no organic solvent, the dosage form is a pharmaceutically acceptable conventional dosage form such as water for injection or pre-serviced water or an aqueous solution freeze-dried product prepared from normal saline. The preparation method of the polydatin pharmaceutical composition mainly comprises the steps of dissolution, filtration, sealed potting, sterilization, lamp examination and the like.

Description

technical field [0001] The invention belongs to the technical field of medicine, and in particular relates to a polydatin pharmaceutical composition free of organic solvents and a preparation method thereof. Background technique [0002] Polydatin (PD) is a monomer extracted from the dried rhizome of Polygonum Cuspidatum Sieb. et Zucc, which can be called resveratrol glycoside. PD is widely distributed in plants with high content and strong biological activity. Modern pharmacological studies have shown that PD has significant effects on cardiomyocytes, vascular smooth muscle cells, anti-platelet aggregation, and improvement of microcirculation. In addition, it can also reduce tissue and organ damage caused by various factors, and has the functions of protecting liver cells, anti-oxidation, and lowering blood lipids. and anti-lipid peroxidation. [0003] The chemical structure of polydatin is 3,4',5-trihydroxystilbene-3-β-D-glucoside (3,4',5-trihydroxy-trans stilbene-3-β-D-...
