Abstract

The invention discloses piracetam orally disintegrating tablets and a preparation method thereof. The main drug of the piracetam orally disintegrating tablets is piracetam, and the auxiliary materials comprise microcrystalline cellulose, mannitol, lactose, crosslinked polyvinylpyrrolidone, sodium cyclamate, menthol, silica gel micropowder and magnesium stearate. The piracetam orally disintegrating tablets can effectively treat senile dementia, have convenience in taking, good taste, rapid disintegration, quick absorption and high bioavailability, and provide convenience for patients with senile dementia who have inconvenience in taking medicine.

Description

1. Technical field [0001] The invention relates to an oral pharmaceutical preparation for treating senile dementia, in particular to a piracetam orally disintegrating tablet that can disintegrate and release rapidly and has good taste. 2. Background technology [0002] Piracetam is a drug for improving brain metabolism, which is a cyclic derivative of r-aminobutyric acid. It can promote ATP in the brain, promote the synthesis of acetylcholine and enhance the conduction of nerve excitation, and has the effect of promoting metabolism in the brain. It can resist brain function damage caused by physical and chemical factors, improve retrograde health caused by hypoxia, enhance memory and improve learning ability. It is clinically used to treat senile dementia and is the first-line drug for the treatment of senile dementia. [0003] The aging trend has increased the number of patients with senile dementia, and our country will enter an aging society. At the same time, it is acco...
