In pharmacology, an effective dose (ED) or effective concentration (EC) is the dose or concentration of a drug that produces a biological response. [1] [2] The term "effective dose" is used when measurements are taken in vivo, while "effective concentration" is used when the measurements are taken in vitro. [3]
A quantal dose response curve shows the percentage of subjects where a response is noted in an all-or-none manner (y axis) over the dose of the drug (x axis). For competition binding assays and functional antagonist assays IC 50 is the most common summary measure of the dose-response curve.
In such cases, the effective dose is the amount and frequency that produces the desired effect, which can vary, and can be greater or less than the therapeutically effective dose. The Certain Safety Factor , also referred to as the Margin of Safety (MOS) , is the ratio of the lethal dose to 1% of population to the effective dose to 99% of the ...
Effective dose: It is the minimum dose or concentration of a drug that produces a biological response in 50% of a population being studied. Median lethal dose: For either drugs or toxins, it is a toxic unit that measures the minimum dose that causes death (lethal dose) in 50% of cases.
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 ...
In clinical trials of Wegovy, which included a higher dose of injectable semaglutide (2.4 mg), people lost an average of almost 15 percent of their body weight.
Effective dose or internal dose may refer to: Effective dose (pharmacology), a dose or concentration of a drug that produces a biological response; Effective dose (radiation), a measure of the stochastic effect on health risk that a radiation dose internal or external to whole or part of the body will have; In toxicology, the internal dose ...
