  2. Dissolution testing - Wikipedia

    en.wikipedia.org/wiki/Dissolution_testing

    In the pharmaceutical industry, drug dissolution testing is routinely used to provide critical in vitro drug release information for both quality control purposes, i.e., to assess batch-to-batch consistency of solid oral dosage forms such as tablets, and drug development, i.e., to predict in vivo drug release profiles.

    In addition, a slow release system will maintain drug concentrations within a therapeutically acceptable range for longer than quicker releasing delivery systems as these result in more pronounced peaks in plasma concentration. The dissolution rate is described by the Noyes–Whitney equation:

  4. Absorption (pharmacology) - Wikipedia

    en.wikipedia.org/wiki/Absorption_(pharmacology)

    The rate of dissolution is a key target for controlling the duration of a drug's effect, and as such, several dosage forms that contain the same active ingredient may be available, differing only in the rate of dissolution. If a drug is supplied in a form that is not readily dissolved, it may be released gradually and act for longer.

  5. Pharmaceutical formulation - Wikipedia

    en.wikipedia.org/wiki/Pharmaceutical_formulation

    The drug (active substance) itself needs to be soluble in aqueous solution at a controlled rate. Such factors as particle size and crystal form can significantly affect dissolution. Fast dissolution is not always ideal. For example, slow dissolution rates can prolong the duration of action or avoid initial high plasma levels.

  6. Sink condition - Wikipedia

    en.wikipedia.org/wiki/Sink_condition

    In pharmaceutics, sink condition is a term mostly related to the dissolution testing procedure.. It means using a sheer volume of solvent, usually about 5 to 10 times greater than the volume present in the saturated solution of the targeted chemical (often the API, and sometimes the excipients) contained in the dosage form being tested.

  9. Micromeritics - Wikipedia

    en.wikipedia.org/wiki/Micromeritics

    Particle size and surface area influence the release of a drug from a dosage form that is administered orally, rectally, parenterally, and topically.Higher surface area brings about intimate contact of the drug with the dissolution fluids in vivo and increases the drug solubility and dissolution.
