Abstract

The development of medical devices (MD) and implants presents unique challenges and requirements not seen in the development of oral solid dosage forms. Through the use of hot melt extrusion (HME), it is possible to engineer novel systems capable of achieving specific geometries and release characteristics that enable the therapy. With extrusion, it is also possible to create systems containing multiple active ingredients leading to treatments for some of the most pressing diseases today, including HIV/AIDS. This chapter discusses the formulation of and processing technologies used for the production MD and implants prepared using HME. Recent examples, including inserts and vaginal rings, are also discussed to illustrate these principles.
