Abstract

The invention belongs to the field of medicinal preparations, and discloses quetiapine fumarate sustained-release tablets and a preparation method thereof. The sustained-release tablets are mainly prepared from the following raw materials in part by mass: 1 part of quetiapine fumarate (based on quetiapine), 0.1 to 1 part of acrylic resin framework material, 0 to 0.5 part of filling agent, 0.04 to 0.05 part of adhesive and 0.01 to 0.02 part of lubricating agent. The sustained-release tablets can comprise hydrophilic gel framework material for adjusting the release rate of the main medicament, and the mass ratio of the quetiapine to the hydrophilic gel framework material is 1: (0.1-0.5). The prepared quetiapine fumarate sustained-release tablets can be used for treating schizophrenia. The sustained-release tablets have the advantages of reducing the administration frequency, improving the administration compliance of a patient, improving the medicinal effect, ensuring application safety and the like, and are more suitable for patients. Meanwhile, the preparation method of the sustained-release tablets is simple and favorable for industrialized large-scale production.

Description

technical field [0001] The invention relates to a pharmaceutical preparation and a preparation method thereof, in particular to a quetiapine fumarate sustained-release tablet and a preparation method thereof. Background technique [0002] Schizophrenia is a psychiatric disease, a persistent, usually chronic, major mental illness, and the most serious of all mental illnesses, characterized by splits in basic personality, thinking, emotion, and behavior, and differences in mental activity and the environment.
