Embodiment 1

[0021] Vilazodone hydrochloride orally disintegrating tablets are prepared from the following components, in the amount of 1000 tablets

[0022]

[0023] Its preparation method comprises the following steps:

[0024] (1) Take vilazodone hydrochloride, dissolve it in 10 times the weight of ethanol solution, add the prescribed amount of PEG6000, stir to dissolve into a clear and transparent solution, and remove the solvent by rotary evaporation to obtain a solid dispersion.

[0025] (2) The obtained solid dispersion is pretreated through a 60-mesh sieve.

[0026] (3) Uniformly mix the pretreated vilazodone hydrochloride solid dispersion with the prescribed amount of lactose, microcrystalline cellulose, and internally added croscarmellose sodium, then dry granulate, add externally added croscarmellose Sodium cellulose, magnesium stearate and acesulfame K are evenly mixed and compressed into tablets.

[0027] test results:

[0028] The disintegration time is 25s, compared wi...

Abstract

The invention belongs to the field of a medicine preparation, and particularly relates to an orally disintegrating tablet containing vilazodone hydrochloride solid dispersions and a preparation method thereof. By aiming at the problems of poor water solubility and low preparation dissolubility of the vilazodone hydrochloride, the vilazodone hydrochloride and carriers are prepared into the solid dispersions for improving the solubility. The solid dispersions are used for preparing the orally disintegrating tablet; the orally disintegrating tablet can fast disintegrate in 30s; and the main medicine dissolubility is obviously improved.
