  2. Therapeutic index - Wikipedia

    en.wikipedia.org/wiki/Therapeutic_index

    For many drugs, severe toxicities in humans occur at sublethal doses, which limit their maximum dose. A higher safety-based therapeutic index is preferable instead of a lower one; an individual would have to take a much higher dose of a drug to reach the lethal threshold than the dose taken to induce the therapeutic effect of the drug.

  3. Effective dose (pharmacology) - Wikipedia

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

    The median effective dose is the dose that produces a quantal effect (all or nothing) in 50% of the population that takes it (median referring to the 50% population base). [6] It is also sometimes abbreviated as the ED 50, meaning "effective dose for 50% of the population". The ED50 is commonly used as a measure of the reasonable expectancy of ...

  4. Drug titration - Wikipedia

    en.wikipedia.org/wiki/Drug_titration

    Therapeutic (green) and side effect dose response curves (red) illustrating a typical starting and progressively increasing titrated doses (arrows). Drug titration is the process of adjusting the dose of a medication for the maximum benefit without adverse effects .

  5. Loading dose - Wikipedia

    en.wikipedia.org/wiki/Loading_dose

    A loading dose is most useful for drugs that are eliminated from the body relatively slowly, i.e. have a long systemic half-life. Such drugs need only a low maintenance dose in order to keep the amount of the drug in the body at the appropriate therapeutic level , but this also means that, without an initial higher dose, it would take a long ...

  6. Therapeutic drug monitoring - Wikipedia

    en.wikipedia.org/wiki/Therapeutic_drug_monitoring

    Therapeutic drug monitoring (TDM) is a branch of clinical chemistry and clinical pharmacology that specializes in the measurement of medication levels in blood. Its main focus is on drugs with a narrow therapeutic range , i.e. drugs that can easily be under- or overdosed. [ 1 ]

  7. Pharmacodynamics - Wikipedia

    en.wikipedia.org/wiki/Pharmacodynamics

    The therapeutic window is the amount of a medication between the amount that gives an effect (effective dose) and the amount that gives more adverse effects than desired effects. For instance, medication with a small pharmaceutical window must be administered with care and control, e.g. by frequently measuring blood concentration of the drug ...

  8. Protective index - Wikipedia

    en.wikipedia.org/wiki/Protective_index

    Quantitatively, it is the ratio given by the toxic dose divided by the therapeutic dose. A protective index is the toxic dose of a drug for 50% of the population (TD 50) divided by the minimum effective dose for 50% of the population (ED 50). A high protective index is preferable to a low one: this corresponds to a situation in which one would ...
