Targeted drug delivery, sometimes called smart drug delivery, [1] is a method of delivering medication to a patient in a manner that increases the concentration of the medication in some parts of the body relative to others. This means of delivery is largely founded on nanomedicine, which plans to employ nanoparticle -mediated drug delivery in ...
Drug delivery is a concept heavily integrated with dosage form and route of administration, the latter sometimes being considered part of the definition. [9] While route of administration is often used interchangeably with drug delivery, the two are separate concepts. Route of administration refers to the path a drug takes to enter the body ...
Endogenous chemical stimuli-responsive drug delivery systems are important in the field of drug delivery because of their ability to harness chemical phenomena within the body to overcome traditional therapeutic release limitations such as temporal release and tissue permeability. These drug delivery systems can be applied both as diagnostic ...
These drug delivery systems have been created to react to the pH environment of diseased or cancerous tissues, triggering structural and chemical changes within the drug delivery system. [3] This form of targeted drug delivery is to localize drug delivery, prolongs the drug's effect, and protect the drug from being broken down or eliminated by ...
Microneedle drug delivery. Microneedles or Microneedle patches or Microarray patches are micron-scaled medical devices used to administer vaccines, drugs, and other therapeutic agents. [ 2 ] While microneedles were initially explored for transdermal drug delivery applications, their use has been extended for the intraocular, vaginal ...
A self-microemulsifying drug delivery system (SMEDDS) is a drug delivery system that uses a microemulsion achieved by chemical rather than mechanical means. That is, by an intrinsic property of the drug formulation, rather than by special mixing and handling. It employs the familiar ouzo effect displayed by anethole in many anise -flavored liquors.
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 ...
An advantage of a transdermal drug delivery route over other types of medication delivery (such as oral, topical, intravenous, or intramuscular) is that the patch provides a controlled release of the medication into the patient, usually through either a porous membrane covering a reservoir of medication or through body heat melting thin layers ...
