Excipient applications in formulation design and drug delivery

The development of drug delivery systems always goes hand-in-hand with the advancement of material science. The novel synthetic or natural functional materials provide opportunities to design optimal drug delivery systems. Emerging trends in the design and development of drug products indicate ever greater need for characterization of excipients and in-depth understanding of their roles in drug delivery applications. This book presents an integrated approach to the characterization and application of excipients. This chapter provides an overview of excipient applications in formulation design and drug delivery with focus on stability implications of drug-excipient interactions, impact of excipients on drug release and bioavailability, the factors that weigh into excipient selection and formulation design, including excipient functionality.
