Abstract

The study investigates the effect of solvent nature on the compression characteristics of wet-granulated tableting mixtures of a new anxiolytic active pharmaceutical ingredient GML-1. Laser diffraction method was used to determine mesh-size distribution of granulated tablet mixtures. Compressibility was determined using the «out-of-die» Heckel (equation 1) and Kawakita models (equation 3).
