Current Strategies For Enhancing Bioavailability Of Poorly Soluble Compounds

By Michelle Gischewski, Scientific Advisor, Drug Product Operations at Eurofins CDMO Alphora Inc.

Improving the therapeutic efficacy of modern drug candidates often hinges on overcoming significant solubility and permeability challenges. As many new chemical entities fall into BCS Class II or IV, the industry is increasingly focused on sophisticated techniques to enhance bioavailability. Key strategies involve manipulating the physical state of the drug substance, such as through the development of amorphous solid dispersions or the utilization of lipid-based delivery systems. These methods are designed to increase the dissolution rate and maintain supersaturation in the gastrointestinal environment, ensuring more consistent absorption.

The selection of these strategies is guided by a deep understanding of the molecule’s physicochemical properties and its behavior in biological systems. By integrating advanced characterization with scalable manufacturing processes, developers can bridge the gap between early-stage discovery and clinical success. Gain deeper insights into optimizing molecular performance and a comprehensive look at the methodologies shaping effective drug delivery and absorption.
