Development of a Clinical Capsule Formulation Containing a Marginally Water Soluble Drug

Abstract

A good clinical development program maximizes the clinical efficacy of a new drug product and, in addition, requires only minimal formulation changes in the transition from clinical to market image product. This study demonstrates the development design as well as the technology utilized to improve the dissolution characteristics of a marginally water soluble drug to be administered in a capsule dosage form for clinical trials. A satisfactory formulation was achieved by controlling drug particle size, selecting an appropriate diluent and incorporating a surfactant.
