Abstract:
Pulmonary drug delivery for managing respiratory diseases has attained a significant maturity level and holds substantial potential for applications in treating systemic diseases. Advancements in pulmonary delivery techniques have driven the innovative development of dry powder inhalers (DPIs), specifically engineered to optimize the efficacy of pulmonary drug delivery. This review examines recent progress in formulation and manufacturing strategies of inhalable dry powder, focusing on prescription design and fabrication approaches for advanced particulate systems. These include the integration of cutting-edge excipients into conventional formulations, nano-based delivery system, composite particles, and a blend of traditional and next-generation processing techniques, all contributing to enhanced drug delivery efficiency and bioavailability. Additionally, this review discusses the latest advancements in DPI devices. This review aims to provide a clear perspective on emerging inhalable dry powder formulation and processing trends for pulmonary delivery, highlighting the critical role of novel particulate platform in advancing pulmonary drug delivery systems.
