Webthe fish have turned over is known as the ED50, which means effective dose for 50 percent of the fish tested. The ED50 of any poison varies depending on the effect measured. In general, the less severe the effect measured, the lower the ED50 for that particular effect. Obviously poisons are not tested in humans in such a fashion. WebThe differences are just nomenclature, and not conceptual. "EC" means effective concentration, and is used for dose-response curves that go up hill. Sometimes it is also used for a curve that goes downhill. "IC" means inhibitory concentration, so is used for dose-response curves that go downhill, because the drug inhibits a response.
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). It is also sometimes abbreviated as the ED50, meaning "effective dose for 50% of the population". The ED50 is commonly used as a measure of the reasonable expectancy of a drug effect, but does not necessarily represent the dose that a clinician might use. This depends on the need for the effe…
