This document discusses novel drug delivery systems and their advantages over traditional methods. Novel drug delivery systems aim to increase drug efficacy, provide site-specific delivery, improve safety, allow controlled drug release, and enhance patient acceptance and compliance. Some examples of novel delivery systems mentioned include liposomes, cyclodextrins, transdermal delivery systems, pulmonary spheres, intravaginal systems like Progestasert, intravesical systems, urethral systems, and implants like Norplant and Gliadel wafer.
