The interaction of a binary/ternary interactive mixture of hydrophobic-hydrophilic materials on the drug distribution and drug release performance in the tablet formulation

The aim of this research was to optimize and determine an interaction of a binary/ternary mixture of hydrophobic-hydrophilic materials (H-HM) on the drug distribution, tablet characteristics, and drug release performance. The interactive mixture (IM) between carrier and H-HM was conducted using a carrier, Pruv and Cab-O-Sil as hydrophilic materials, magnesium stearate as a hydrophobic material, and a micronized nifedipine as a drug model. These interactions between binary and ternary mixtures of H-HM were assessed by a simplex centroid design (SCD) approach. The homogeneity of IM between drug and carrier was achieved at more time of mixing time. Unique effects and interactions of H-HM were observed on the drug distribution and drug release. Furthermore, the SCD had successfully determined the optimum design space of IM in the ternary mixture of H-HM.
