Abstract

The invention relates to a vilazodone hydrochloride composition and a preparation method thereof. The composition includes vilazodone hydrochloride, a microcarrier and pharmaceutically acceptable excipients for an oral solid preparation. The preparation method is as below: mixing and crushing vilazodone hydrochloride and the microcarrier, and evenly mixing the mixture with pharmaceutically acceptable excipients for oral solid preparation. The obtained composition preparation has greatly improved dissolution in vitro, and in vivo bioavailability reaching bioequivalence to VIIBRYD.
