  2. Onset of action - Wikipedia

    en.wikipedia.org/wiki/Onset_of_action

    Onset of action is the duration of time it takes for a drug's effects to come to prominence upon administration. With oral administration , it typically ranges anywhere from 20 minutes to over an hour, depending on the drug in question.

  3. Pharmacodynamics - Wikipedia

    en.wikipedia.org/wiki/Pharmacodynamics

    The effects can include those manifested within animals (including humans), microorganisms, or combinations of organisms (for example, infection). Pharmacodynamics and pharmacokinetics are the main branches of pharmacology , being itself a topic of biology interested in the study of the interactions of both endogenous and exogenous chemical ...

  4. Drug action - Wikipedia

    en.wikipedia.org/wiki/Drug_action

    The action of drugs on the human body (or any other organism's body) is called pharmacodynamics, and the body's response to drugs is called pharmacokinetics. The drugs that enter an individual tend to stimulate certain receptors, ion channels, act on enzymes or transport proteins. As a result, they cause the human body to react in a specific way.

  5. Cmax (pharmacology) - Wikipedia

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

    C max is the maximum (or peak) serum concentration that a drug achieves in a specified compartment or test area of the body after the drug has been administered and before the administration of a second dose. [1] It is a standard measurement in pharmacokinetics.

  6. Area under the curve (pharmacokinetics) - Wikipedia

    en.wikipedia.org/wiki/Area_under_the_curve...

    In pharmacology, the area under the plot of plasma concentration of a drug versus time after dosage (called “area under the curve” or AUC) gives insight into the extent of exposure to a drug and its clearance rate from the body. [2]

  7. Hydrocodone - Wikipedia

    en.wikipedia.org/wiki/Hydrocodone

    Some references state that the analgesic action of hydrocodone begins in 20–30 minutes and lasts about 4–8 hours. [28] The manufacturer's information says onset of action is about 10–30 minutes and duration is about 4–6 hours. [29] Recommended dosing interval is 4–6 hours. Hydrocodone reaches peak serum levels after 1.3 hours. [30]

  8. NPH insulin - Wikipedia

    en.wikipedia.org/wiki/NPH_insulin

    NPH insulin is cloudy and has an onset of 1–3 hours. Its peak is 6–8 hours and its duration is up to 24 hours. [9]It has an intermediate duration of action, meaning longer than that of regular and rapid-acting insulin, and shorter than long acting insulins (ultralente, glargine or detemir).

  9. Plateau principle - Wikipedia

    en.wikipedia.org/wiki/Plateau_Principle

    The plateau principle is a mathematical model or scientific law originally developed to explain the time course of drug action (pharmacokinetics). [1] The principle has wide applicability in pharmacology, physiology, nutrition, biochemistry, and system dynamics.
