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.
