ONCLUSIONS
Medical devices in drug delivery are used to provide efficient drug
transportation to the target site by enabling drug to overcome biological
barriers. Devices can be manufactured and manipulated to suit particular drug
formulations and therapeutic applications, and hence many devices are highly
sophisticated in their design and technology of operation. This particularly
includes devices used for pulmonary, nasal and transdermal delivery. Drug
delivery devices may not only facilitate drug targeting but can also provide
controlled release systems and can be made as inserts such as in case of ocular
and vaginal drug delivery. For safety reasons, such inserts should ideally be
made of biocompatible and biodegradable materials. The design of medical
devices can be engineered to suit more than one application and deliver
formulations having different properties. When devices are manufactured, the
potential chemical interaction between the device and formulation should be
studied.
