Efficacy

Abstract

“Efficacy” is defined by Webster as “the power to produce an effect.” A good example of the use of this word is found in the science of pharmacology, where the maximal effect of a drug is referred to as either “maximal efficacy” or simply “efficacy.” Consider two drugs that are available for pain relief. Aspirin can provide relief up to moderate pain intensities, while morphine relieves almost all levels of pain. Therefore, the opiate has a much greater efficacy for pain reduction (of course, there are side effects that must be considered).
