  2. Biological half-life - Wikipedia

    en.wikipedia.org/wiki/Biological_half-life

    Biological half-life (elimination half-life, pharmacological half-life) is the time taken for concentration of a biological substance (such as a medication) to decrease from its maximum concentration (C max) to half of C max in the blood plasma. [1][2][3][4][5] It is denoted by the abbreviation . [2][4] This is used to measure the removal of ...

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

    The plasma half-life or half life of elimination is the time required to eliminate 50% of the absorbed dose of a drug from an organism. Or put another way, the time that it takes for the plasma concentration to fall by half from its maximum levels.

  4. Clearance (pharmacology) - Wikipedia

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

    Clearance (pharmacology) In pharmacology, clearance ( ) is a pharmacokinetic parameter representing the efficiency of drug elimination. This is the rate of elimination of a substance divided by its concentration. [1] The parameter also indicates the theoretical volume of plasma from which a substance would be completely removed per unit time.

    A biological half-life or elimination half-life is the time it takes for a substance (drug, radioactive nuclide, or other) to lose one-half of its pharmacologic, physiologic, or radiological activity.

    Midazolam is a short-acting benzodiazepine in adults with an elimination half-life of 1.5–2.5 hours. [13] In the elderly, as well as young children and adolescents, the elimination half-life is longer. [44][66] Midazolam is metabolised into an active metabolite alpha-hydroxymidazolam.
