Problems solved by technology

[0015] In summary, as a symptomatic drug for the treatment of memory loss after Alzheimer's disease and cerebrovascular disease, Aniracetam has better curative effect than Piracetam, and has good safety; even though Aniracetam has many advantages, but The dosage forms currently used clinically are only ordinary tablets and granules, and their production costs are very high, which greatly limits the general use of clinical senile dementia patients, and tablets and granules are not convenient for accurate dose division. Individualization of doses for different Alzheimer's patients is extremely inconvenient
Aniracetam is a poorly soluble drug, and the bioavailability of ordinary tablets and granules is low

Abstract

The invention provides an aniracetam drop pill wherein polyethylene glycol is selected from a plurality of drop pill base materials, a melting method is employed for preparing solid dispersions, based on this, the admission of the surface active agent and the integration boosting agent can facilitate the dissolving of drop pills. The invention has the advantages of convenient swallowing, rapid absorption, high biological availability, easy dosage dividing, thus is suitable for senile dementia patients.

Description

[0001] The technical field [0002] The invention belongs to medical technology, in particular to a medicine drop pill preparation technology. Background technique [0003] With the improvement of social living standards, the world's population is aging, and the average life expectancy of human beings is extended. It is reported that by 2000, the world's population will be close to 6 billion, and the elderly will be nearly 590 million. The elderly in my country will be about 100 million, and the proportion of the elderly will increase sharply. Cerebrovascular incidence increased significantly. Due to the rapid development of corresponding drug treatment, the mortality rate and disability rate of cerebrovascular diseases have been significantly reduced, while the number of patients with stroke sequelae and arteriosclerosis combined with mental and emotional disorders has increased sharply. There are about 10 million people in the world. According to data analysis, The disease i...
