Drug delivery systems have been around for many years, but there are a few recent applications of drug delivery that warrant 1. Drug delivery to the brain: Many drugs can be harmful when administered systemically; the brain is very sensitive to medications and can easily cause damage if a drug is administered directly into the bloodstream.
Neural drug delivery is the next step beyond the basic addition of growth factors to nerve guidance conduits. Drug delivery systems allow the rate of growth factor release to be regulated over time, which is critical for creating an environment more closely representative of in vivo development environments.
An application of stretch-triggered drug delivery systems is the delivery of chemotherapy triggered by esophageal stent expansion. [4] Also, the incorporation of several drugs into stretch-triggered autonomous drug release systems is a possibility, allowing drugs to be released by the same or different signals. [ 1 ]
A drug carrier or drug vehicle is a substrate used in the process of drug delivery which serves to improve the selectivity, effectiveness, and/or safety of drug administration. [1] Drug carriers are primarily used to control the release of drugs into systemic circulation.
Drug delivery devices are specialized tools for the delivery of a drug or therapeutic agent via a specific route of administration. Such devices are used as part of one or more medical treatments . Contents
Conventional drug delivery is limited by the inability to control dosing, target specific sites, and achieve targeted permeability. Traditional methods of delivering therapeutics to the body experience challenges in achieving and maintaining maximum therapeutic effect while avoiding the effects of drug toxicity.
Drug eluting implants can be used in the management and treatment of a variety of medical conditions. Traditional drug delivery methods have potential disadvantages that have led to the development of different drug delivery techniques across most body systems, many of which can improve treatment efficacy.

Gated drug delivery systems are a method of controlled drug release that center around the use of physical molecules that cover the pores of drug carriers until triggered for removal by an external stimulus. Gated drug delivery systems are a recent innovation in the field of drug delivery and pose as a promising candidate for future drug ...
