Problems solved by technology

[0003] Since Nicergoline is sensitive to heat and humidity, it is unstable during the granulation and drying process of the preparation, which will easily lead to a decrease in content and an increase in related substances, thereby affecting product quality and curative effect
The direct tableting process has high requirements on the fluidity, compressibility and tableting equipment of excipients, which significantly increases the production cost

Abstract

The invention discloses a nicergoline pill and a preparation method thereof. Preparation comprises nicergoline, diluent, disintegrant, adhesive, lubricant and film coating premixing agent. The preparation method includes uniformly mixing the diluent with the internally added disintegrant; preparing blank particles in proper quantity by the adhesive, drying, pelleting and reserving; independently pelleting main drug by the proper adhesive, quickly drying, pelleting and reserving at lower temperature; uniformly mixing the main drug particles with the blank particles, adding externally added auxiliaries, mixing totally, pressing, coating a thin film and packaging. Accordingly, flowability of the particles is guaranteed, the drug can be dissolved beneficially, and more importantly, the problems that content of the main drug and the auxiliaries is lowered and relevant substances are increased due to the high drying temperature and long time in pelleting are avoided. Compared with the prior art, the nicergoline pill has the advantages of reasonable components, simplicity in process, unique preparation method, high dissolving degree, good stability of the preparation, low cost and the like.

Description

technical field [0001] The present invention relates to a tablet with α-receptor blocking effect and vasodilator effect, which is used for improving depression and affective disorder caused by sequelae of cerebral infarction, and for treating vascular dementia and its preparation method, which belongs to the pharmaceutical preparation technology field. Background technique [0002] my country has gradually entered into an aging country. It is estimated that from 2003 to 2010, my country's population aging will accelerate. The population over 60 years old in my country will increase to 173 million, and the proportion of the elderly population will rise to 12.54%. At the same time, demand for drugs to treat Alzheimer's disease brought on by an aging population has been growing steadily. Nicergoline has α-receptor blocking effect and vasodilation effect, which can strengthen the energy metabolism of brain cells, increase the utilization of oxygen and glucose; promote the conve...
