What is Controlled Drug Delivery

The research and design of new combined products are of high interest and importance for public health. That is why the design of new technologies in medical devices requires the use of robust procedures, such as the use of ionizing radiation. These methodologies favor the modification of the surface of the medical device for the incorporation of analgesic, anti-inflammatory, and antimicrobial drugs. These medical devices will have the ability to generate prophylactic effects against inflammatory and infectious processes when patients undergo a surgical medical procedure. That is why the FDA describes a combination product as “therapeutic and diagnostic products that combine drugs, devices, and biological products.” In this chapter, the characteristics and advantages of using the different ionizing radiation methodologies mentioned previously for designing these new drug-medical device combination products are explored. In the same way, quality control tests are described for these products at the research or industrial level.
