    en.wikipedia.org/wiki/Layered_double_hydroxides

    Layered double hydroxides (LDH) are a class of ionic solids characterized by a layered structure with the generic layer sequence [AcB Z AcB] n, where c represents layers of metal cations, A and B are layers of hydroxide (OH −) anions, and Z are layers of other anions and neutral molecules (such as water).

    en.wikipedia.org/wiki/Osmotic-controlled_Release...

    The drug is expelled via the laser-drilled hole visible on the left side of the tablet. The osmotic-controlled release oral delivery system (OROS) is an advanced controlled release oral drug delivery system in the form of a rigid tablet with a semi-permeable outer membrane and one or more small laser drilled holes in it.

  4. Hydrotalcite - Wikipedia

    en.wikipedia.org/wiki/Hydrotalcite

    Hydrotalcite, or formerly also völknerite, [6] is a layered double hydroxide (LDH) of general formula Mg 6 Al 2 CO 3 (OH) 16 ·4 H 2 O, whose name is derived from its resemblance with talc and its high water content. Multiple structures containing loosely bound carbonate ions exist.

  5. 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.

  6. Route of administration - Wikipedia

    en.wikipedia.org/wiki/Route_of_administration

    A medical professional injects medication into a gastric tube. Many drugs as tablets, capsules, or drops are taken orally. Administration methods directly into the stomach include those by gastric feeding tube or gastrostomy. Substances may also be placed into the small intestines, as with a duodenal feeding tube and enteral nutrition. Enteric ...

  7. 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.

  8. Transdermal patch - Wikipedia

    en.wikipedia.org/wiki/Transdermal_patch

    The drug layer is a liquid compartment containing a drug solution or suspension separated by the adhesive layer. The drug reservoir is totally encapsulated in a shallow compartment molded from a drug-impermeable metallic plastic laminate, with a rate-controlling membrane made of a polymer like vinyl acetate on one surface.

  9. Enteric coating - Wikipedia

    en.wikipedia.org/wiki/Enteric_coating

    An enteric coating is a polymer barrier applied to oral medication that prevents its dissolution or disintegration in the gastric environment. [1] This helps by either protecting drugs from the acidity of the stomach, the stomach from the detrimental effects of the drug, or to release the drug after the stomach (usually in the upper tract of the intestine).
