Preparation and in vitro Release Evaluation of Puerarin Sustained-Release Tablet
Objective:To prepare puerarin sustained-release tablet and investigate its in vitro release mechanism.Method:With mixture of different types of hydroxypropyl methylcellulose(HPMC K100M
HPMC E4M) as skeleton material
puerarin sustained-release tablet was prepared by wet granulation tabletting method
with release of puerarin as index
formulation of sustained-release tablet was optimized by single factor test;In vitro release model of puerarin skeleton sustained-release tablet was investigated by determining release.Result:Optimized prescription was:HPMC K100M and HPMC E4M as compound matrix
the mass fraction of them were 10%
20%
respectively;Lactose as filler
the mass fraction of it was 30%.Release law of prepared sustained-release tablet complied with Ritger-Peppas equation curve
release process was synergistic reaction of drug diffusion and skeleton dissolution.Conclusion:Prescription of prepared puerarin sustained-release tablet was reasonable
preparation technology was feasible
prepared puerarin sustained-release tablet had good in vitro release characteristics in 12 h.
