  2. Drug delivery - Wikipedia

    en.wikipedia.org/wiki/Drug_delivery

    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.

  3. Stimuli-responsive drug delivery systems - Wikipedia

    Systems used with pH-responsive polymers include implantable hydrogels and micro- and nanoparticles. pH-responsive drug delivery systems are particularly suitable for the design of chemotherapeutic delivery systems due to the naturally low pH found in tumor microenvironments, but can be applied in other disease settings where the pH of the ...

  4. Drug delivery to the brain - Wikipedia

    The most promising drug delivery system is using nanoparticle delivery systems, these are systems where the drug is bound to a nanoparticle capable of traversing the blood–brain barrier. The most promising compound for the nanoparticles is Human Serum Albumin (HSA).

  5. Targeted drug delivery - Wikipedia

    en.wikipedia.org/wiki/Targeted_drug_delivery

    The goal of a targeted drug delivery system is to prolong, localize, target and have a protected drug interaction with the diseased tissue. The conventional drug delivery system is the absorption of the drug across a biological membrane, whereas the targeted release system releases the drug in a dosage form.

  6. Drug carrier - Wikipedia

    en.wikipedia.org/wiki/Drug_carrier

    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.

  7. Gated drug delivery systems - Wikipedia

    en.wikipedia.org/wiki/Gated_drug_delivery_systems

    The history of gated drug delivery systems starts in the mid-1960s when the concept of zero order controlled drug delivery was first thought of. Researchers raced to be able to find a drug delivery platform that would be able to have perfectly sustained drug release.

  8. Route of administration - Wikipedia

    en.wikipedia.org/wiki/Route_of_administration

    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. [49]

  9. Intranasal drug delivery - Wikipedia

    The first drug delivery system is often dated to the 1950s, when Smith Kline & French Laboratories introduced the Spansule technology. [2] Between 1950s and 1980s, there were four drug release systems developed for oral and transdermal applications: dissolution, diffusion, osmosis, and ion-exchange controlled release. [3]
