Introduction

Oral drug delivery remains the preferred route for drug administration due to its convenience, non-invasiveness, and patient compliance. However, the gastrointestinal tract presents numerous barriers that limit the bioavailability and efficacy of many drugs. These challenges include enzymatic degradation, pH variations, poor permeability across the intestinal epithelium, and first-pass metabolism. Overcoming these hurdles requires a deep understanding of the underlying physiological and physicochemical principles, as well as the application of advanced drug delivery technologies. This comprehensive training course is designed to provide participants with a thorough knowledge of oral drug delivery systems, formulation strategies, and techniques to enhance drug absorption and bioavailability. Participants will explore conventional and novel drug delivery approaches, including controlled-release formulations, nanoparticles, and targeted delivery systems.
