Abstract

The invention relates to the field of pharmaceutical preparation, and in particular relates to a gastrodin double-pulse drug-release preparation. The preparation consists of quick release pellets and slow-release pellets, wherein the quick release pellets consist of gastrodin quick release pellet cores and quick release layers, and the slow-release pellets consist of gastrodin slow-release pellet cores, swelling layers and time-lag layers. By utilizing the gastrodin double-pulse drug-release preparation provided by the invention, the application range of water-soluble medicinal gastrodin with short half-life period is widened in the insomnia treatment field, and the pulse drug release of the double-pulse drug-release preparation can be realized in two key time points at fixed times in an insomnia process; moreover, problems of difficulty in sleeping and early awakening of insomnia patients can be solved, and the sleeping time and quality are ensured.

Description

technical field [0001] The invention relates to the field of pharmaceutical preparations, in particular to a gastrodin double pulse release preparation. Background technique [0002] With the accelerated pace of life in today's society and the increase in mental stress, insomnia has become one of the ubiquitous sufferings of people, and it is one of the most common clinical symptoms except pain. Long-term lack of sleep will lead to daytime sleepiness and decreased concentration of patients, affecting physical and mental health and quality of life, and even depression in severe cases.
