Preformulation Studies and Their Parallel Role in Analytical and Formulation Development

Abstract: - Preformulation studies serve as the scientific foundation of pharmaceutical product development by generating essential physicochemical information about a drug substance. These data guide the selection of excipients, formulation strategy, dose design, analytical method development, and stability assessment. The integration of preformulation with analytical sciences ensures accurate characterization of the drug molecule, while its parallel role in formulation development supports the creation of stable, safe, and efficacious dosage forms. This article discusses the strategic importance of preformulation, its alignment with analytical method development.
