ABSTRACT
Objective:
To screen the optimal formula and preparation process of vitamin B1 ( VB1 ) sustained-release tablets.Methods:
The single-factor tests were used to investigate the type of filler, type and amount of matrix material hydroxypropyl methycel-lulose(HPMC), type and amount of retarder, tablet weight and core hardness. The orthogonal tests were used to investigate the amount of HPMC and ethyl cellulose( EC) and the core hardness.Results:
The optimum formula was as followsHPMC accounted for 50% of the tablet weight, EC accounted for 20%, the filler was lactose, the tablet weight was 200 mg and the tablet core hardness was 50 N.Conclusion:
The prepared sustained-release tablets have significant controlled-release property, which provides reference for the devel-opment of new dosage form for VB1 .
