Abstract

The invention discloses ziprasidone hydrochloride solid dispersible tablets and a hot melt extrusion method thereof. Based on ziprasidone hydrochloride as a main component, one or two of mixed carriers of copolyvidone S630 or HPMCAS-HF (hydroxypropyl methylcellulose acetate succinate) as a base, a coating material is added, and the glass transition temperature of an extruded mixture can also be reduced; then, a surfactant is added. The ziprasidone hydrochloride solid dispersible tablets are prepared through steps as follows: the raw and auxiliary materials are evenly mixed by a three-dimensional mixing machine, extruded by a hot melt extruder at a high temperature and ground into powder with proper size; the powder is then mixed with a fixed quantity of filler, disintegrant and lubricant sufficiently and uniformly, and direct tableting is preformed, and the ziprasidone hydrochloride solid dispersible tablets are prepared. The prepared ziprasidone hydrochloride solid dispersible tabletshave the advantages that the problem of poor in-vitro dissolution of ziprasidone hydrochloride is solved, bioavailability of ziprasidone hydrochloride under the condition of empty stomach is improved, and the treatment effect of the tablets is improved finally.

Description

technical field [0001] The invention belongs to the field of pharmaceutical preparations, and relates to a hot-melt extrusion method for preparing ziprasidone hydrochloride solid dispersion. Background technique [0002] Ziprasidone hydrochloride (Formula 1) is a kind of second-generation atypical antipsychotic drugs. It is clinically used to treat schizophrenia, manic episodes of bipolar disorder and agitation symptoms of polar phase in patients with schizophrenia. Unlike typical antipsychotic drugs, studies have shown that it acts through antagonism of D2, 5-HT2A, 5-HT2C and 5-HT1 receptors. Due to its relatively high affinity for 5-HT2A receptors, the probability of ESP occurring in the extrapyramidal system is greatly reduced. [0003] [0004] Formula 1: Ziprasidone hydrochloride. [0005] However, ziprasidone hydrochloride belongs to class II in the biopharmaceutical classification system, and is a poorly water-soluble drug with low solubility, which leads to a d...
