ABSTRACT
AIM:
To elucidate the effect of HPMC on the floating and releasing performances of Zuojin Gastric Floating Sustained-Release Tablets(ZJ-GFST) and to select the optimum matrix adjuvant for ZJ-GFST.METHODS:
Seven kinds of ZJ-GFST from pharmaceutical factories as main adjuvant respectively.The floating lag time and the sustained floating time were used to evaluate the floating performance of ZJ-GFST.The accumulative releasing rates of berberine and palmatine in vitro were used to evaluate the releasing efficiency of ZJ-GFST.RESULTS:
The tablets prepared with HPMC MK-100000 and MK-15000 disintegrated quickly when contacting with water, and the tablets prepared with HPMC MK-100M and MK-4000 had too long floating lag time and low release speed.The tablets prepared with HPMC 60RT-50、K-4M and MK-1500 all possessed short floating lag time and long sustained floating time and suitable drug releasing rate.CONCLUSION:
The selected HPMC is 60RT-50.
