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 ...
Drug delivery to the brain. Drug delivery to the brain is the process of passing therapeutically active molecules across the blood–brain barrier into the brain. This is a complex process that must take into account the complex anatomy of the brain as well as the restrictions imposed by the special junctions of the blood–brain barrier.
Cervical drug delivery is a route of carrying drugs into the body through the vagina and cervix. This is a form of localized drug delivery that prevents the drugs from impacting unintended areas of the body, which can lower side effects of toxic drugs such as chemotherapeutics . Cervical drug delivery has specific applications for a variety of ...
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 ...
Intrathecal administration is a route of administration for drugs via an injection into the spinal canal, or into the subarachnoid space so that it reaches the cerebrospinal fluid (CSF). It is useful in several applications, such as for spinal anesthesia, chemotherapy, or pain management. This route is also used to introduce drugs that fight ...
Modified-release dosage. Modified-release dosage is a mechanism that (in contrast to immediate-release dosage) delivers a drug with a delay after its administration (delayed-release dosage) or for a prolonged period of time (extended-release [ER, XR, XL] dosage) or to a specific target in the body (targeted-release dosage). [1]
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.
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 ...
