Characterization of Tableting Speed-Dependent Deformation Properties of Active Pharmaceutical Ingredients in Powder Mixtures Using Out-of-Die Method.

A quantitative evaluation method for determining the effect of tableting speed on the compression properties of pharmaceutical powders was investigated in this study. Cilostazol and ibuprofen were used as active pharmaceutical ingredients (APIs) and mixed with lactose monohydrate and microcrystalline cellulose. Viscoelasticity was examined to evaluate the raw material, and stress relaxation tests were conducted to determine the apparent viscosity and elasticity coefficients of the placebo and two APIs.
