Excipients are important components of drug formulations, playing a critical role in ensuring the safety, efficacy, and stability of pharmaceutical products. In recent years, there has been a growing demand for advanced drug delivery systems that can improve the bioavailability, targeting, and sustained release of therapeutics. The development of these systems relies heavily not only on excipients but also on the use of processed excipients, which have been specifically designed and engineered to meet the unique challenges and requirements of advanced drug delivery. This new volume provides a comprehensive overview of the state-of-art research on processed excipients and their utilization in fabrication of advanced drug delivery. Beginning with an introduction and overview, the volume covers novel solid dosage forms, pharmaceutical and biomedical applications, nasal drug delivery, ocular drug delivery, transdermal drug delivery, parenteral medication delivery, pharmacokinetics and pharmacodynamics of processed excipients, and much more.
