  2. Elimination rate constant - Wikipedia

    en.wikipedia.org/wiki/Elimination_rate_constant

    The elimination rate constant K or K e is a value used in pharmacokinetics to describe the rate at which a drug is removed from the human system. [1] It is often abbreviated K or K e. It is equivalent to the fraction of a substance that is removed per unit time measured at any particular instant and has units of T −1.

  3. Clearance (pharmacology) - Wikipedia

    en.wikipedia.org/wiki/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.

  4. Pharmacokinetics - Wikipedia

    en.wikipedia.org/wiki/Pharmacokinetics

    Pharmacokinetics (from Ancient Greek pharmakon "drug" and kinetikos "moving, putting in motion"; see chemical kinetics), sometimes abbreviated as PK, is a branch of pharmacology dedicated to describing how the body affects a specific substance after administration. [1]

  5. Plateau principle - Wikipedia

    en.wikipedia.org/wiki/Plateau_Principle

    Half-life has units of time, and the elimination rate constant has units of 1/time, e.g., per hour or per day. An equation can be used to forecast the concentration of a compound at any future time when the fractional degration rate and steady state concentration are known:

  6. Biological half-life - Wikipedia

    en.wikipedia.org/wiki/Biological_half-life

    where k is the reaction rate constant. Such a decay rate arises from a first-order reaction where the rate of elimination is proportional to the amount of the substance: [39] =. The half-life for this process is [39] = ⁡.

  7. Elimination (pharmacology) - Wikipedia

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

    Pharmacokinetics studies the manner and speed with which drugs and their metabolites are eliminated by the various excretory organs. This elimination will be proportional to the drug's plasmatic concentrations. In order to model these processes a working definition is required for some of the concepts related to excretion.

  8. Drug metabolism - Wikipedia

    en.wikipedia.org/wiki/Drug_metabolism

    Drug metabolism is the metabolic breakdown of drugs by living organisms, usually through specialized enzymatic systems. More generally, xenobiotic metabolism (from the Greek xenos "stranger" and biotic "related to living beings") is the set of metabolic pathways that modify the chemical structure of xenobiotics, which are compounds foreign to an organism's normal biochemistry, such as any drug ...

  9. Pharmacology of ethanol - Wikipedia

    en.wikipedia.org/wiki/Pharmacology_of_ethanol

    The rate of elimination of ethanol is also increased at very high concentrations, such as in overdose, again more closely following first-order kinetics, with an elimination half-life of about 4 or 4.5 hours (a clearance rate of approximately 6 L/hour/70 kg). This is thought to be due to increased activity of CYP2E1.
