  2. Therapeutic index - Wikipedia

    en.wikipedia.org/wiki/Therapeutic_index

    The therapeutic index varies widely among substances, even within a related group. For instance, the opioid painkiller remifentanil is very forgiving, offering a therapeutic index of 33,000:1, while Diazepam, a benzodiazepine sedative-hypnotic and skeletal muscle relaxant, has a less forgiving therapeutic index of 100:1.

  3. EC50 - Wikipedia

    en.wikipedia.org/wiki/EC50

    While relying on a graph for estimation is more convenient, this typical method yields less accurate and precise results. [6] The response or effect, E, is dependent on both the binding of the drug and the drug-bound receptor. The agonist that binds to the receptor and initiates the response is usually abbreviated A or D. At low agonist ...

    Another use is in the therapeutic drug monitoring of drugs with a narrow therapeutic index. For example, gentamicin is an antibiotic that can be nephrotoxic (kidney damaging) and ototoxic (hearing damaging); measurement of gentamicin through concentrations in a patient's plasma and calculation of the AUC is used to guide the dosage of this drug ...

  5. Pharmacokinetics - Wikipedia

    en.wikipedia.org/wiki/Pharmacokinetics

    Population pharmacokinetics seeks to identify the measurable pathophysiologic factors and explain sources of variability that cause changes in the dose-concentration relationship and the extent of these changes so that, if such changes are associated with clinically relevant and significant shifts in exposures that impact the therapeutic index ...

    en.wikipedia.org/wiki/Dose–response_relationship

    A dose–response curve is a coordinate graph relating the magnitude of a dose (stimulus) to the response of a biological system. A number of effects (or endpoints) can be studied. The applied dose is generally plotted on the X axis and the response is plotted on the Y axis.

  8. Trough level - Wikipedia

    en.wikipedia.org/wiki/Trough_level

    The name comes from the idea that on a graph of concentration versus time, the line forms a U-shaped trough at the lowest region, before a new dose sends it higher again. The usual criterion is concentration in the blood serum , although in some instances local concentration within tissues is relevant.
