Abstract

The invention relates to a hesperetin emulsion and a preparation method thereof, and belongs to the technical field of pharmaceutics. The hesperetin emulsion comprises the following components in percentage by mass: 0.3-3% of hesperetin, 10-30% of an oil phase solvent, 3.0-20% of an emulsifier, 0.03-0.6% of a stabilizer and 1-5% of an isoosmotic adjusting agent. The injection emulsion further comprises a pH regulator, a hesperetin solubilizer and the balance of water for injection, the pH value of the injection emulsion is 7.0-8.5, the hesperetin drug loading capacity is greatly improved, and the problem of rapid metabolism due to oral absorption is solved.

Description

technical field [0001] The invention belongs to the field of pharmaceutical preparations, and in particular relates to a hesperetin emulsion and a preparation method thereof. Background technique [0002] Hesperetin is mainly found in the fruits of citrus plants of Rutaceae, and belongs to dihydroflavonoids, with a structural formula such as figure 1 shown. It has been confirmed that hesperetin has a variety of pharmacological activities, including antibacterial, anti-inflammatory, anti-oxidation, anti-virus, anti-allergic, regulating blood lipids and enhancing immunity. In recent years, studies have reported that hesperetin and its derivatives also have anti-Alzheimer's disease, anti-Parkinson's disease, hypoglycemic, anti-snake venom hemocoagulase, anti-fibrosis and other effects. However, hesperetin is easily metabolized in the body, and it is difficult to maintain the blood concentration. Therefore, oral administration or traditional injection administration cannot gua...
