Simultaneous Optimization of Capsule and Tablet Formulation Using Response Surface Methodology

The study described herein was undertaken to simultaneously optimize the composition of tablet and capsule formulation of an insoluble experimental drug, and to learn more about the effect of the interaction between the ingredients on the basic properties of the final dosage form. Four independent variables were varied in a set of statistically designed experiments, and a number of properties evaluated. A substantial saving in development time and quantity of drug was thereby achieved.
