Abstract

The invention discloses a clozapine tablet and a preparation method thereof. The clozapine tablet is prepared from the main material ingredients in mass fraction: 25 parts of clozapine, 61.2 parts ofmicrocrystalline cellulose, 3.8 parts of lactose, the defined amount of povidone, 0.5 part of magnesium stearate, 1.4 parts of talcum powder and 0.4 part of silicon dioxide. The preparation method ofthe clozapine tablet comprises the following specific operation steps: step 1, sieving the clozapine by a 100-mesh sieve for standby application; step 2, weighing the clozapine, the microcrystalline cellulose and the lactose according to a formula in the claim 1 and jointly putting into a wet mixing granulator to be mixed evenly; step 3, weighing the defined amount of the povidone and adding waterto dissolve the povidone to be prepared into a water solution; step 4, adding the defined amount of binding agent into mixed powder in the last step to be prepared into an appropriate flexible material. According to the clozapine tablet disclosed by the invention, existing general auxiliary materials are utilized, and the problems that an existing formula has poor compressibility, tablet core hardness is poor, and the tablet split phenomenon happens in a conveying process are solved by optimizing the formula and a production technology.

Description

technical field [0001] The invention relates to the technical field of medicine and medicine production, in particular to a clozapine tablet and a preparation method thereof. Background technique [0002] Mental illness refers to the general term for disorders in which the incidence of brain functional activities is disordered, resulting in varying degrees of impairment of mental activities such as cognition, emotion, behavior, and will. There are many pathogenic factors: congenital heredity, personality traits and physical factors, organic factors, social environmental factors, etc. Many mental patients have delusions, hallucinations, delusions, emotional disorders, erratic crying, talking to themselves, weird behavior, and decreased willpower.
