Evaluation of dissolution consistency of Iloperidone Tablets / 药物评价研究

ABSTRACT

Objective To compare the dissolution curves of reference preparation and self-prepared Iloperidone Tablets in four different pH dissolution media (0.1 mol/L HC1 solution,pH 4.5 acetate buffer solution,pH 6.8 phosphate buffer solution,and water).Methods The solubility of Iloperidone in different pH solutions was measured,the dissolution curves of two preparations in four different pH dissolution media were determined by HPLC,and the similarity was investigated according to the f2 factor method.Results The f2 factors between reference preparation and self-prepared Iloperidone Tablets in four different media were more than 50.Conclusion The two preparations are equivalent in four different pH dissolution media in vitro.
