Abstract

The invention relates to a vinpocetine oral self-micro-emulsifying drug delivery system and the preparation method. The vinpocetine oral self-micro-emulsifying drug delivery system is composed of vinpocetine, fat phase, emulsifier and coemulsifier. The mass ratio percentage preferential scope of the ingredients is that the vinpocetine occupies 1-10 per cent, the fat phase occupies 20-60 per cent, the emulsifier occupies 25-70 per cent and the coemulsifier occupies 0-25 per cent. The vinpocetine oral self-micro-emulsifying drug delivery system can be spontaneously emulsified into micro-emulsion with 10-100 mm granule diameter after taken orally, promoting drug to be quickly absorbed. The drug delivery system has the advantages of improving the solubility of the vinpocetine in water, improving the availability of the vinpocetine and eliminating the influence of food to the absorption and bioavailability of the vinpocetine.

Description

technical field [0001] The invention relates to the technical field of medicine, and relates to a new oral drug delivery system for vinpocetine, specifically, an oral self-microemulsification drug delivery system for vinpocetine and a preparation method thereof. Background technique [0002] Vinpocetine (Vinpocetine) is a derivative of the indole alkaloid vincamine extracted from the plant Vinca oleander of the Apocynaceae family. It is a brain circulation metabolism improving agent, which can improve the blood circulation of the brain and promote the energy of the brain. Metabolism, has a good curative effect on the prevention and treatment of cerebral arteriosclerosis, sequelae of cerebral hemorrhage and hyperviscosity of hypertensive coronary heart disease, and can be used to improve brain function, enhance memory, improve mood, and improve aging hearing and vision Abnormal, delay brain aging, long-term application safety and high tolerance. [0003] Vinpocetine was succ...
