Which term refers to the immediate response of a body to a drug?

The term that refers to the immediate response of a body to a drug is drug action. This encompasses the biochemical and physiological effects that occur after a drug is administered, illustrating how the drug interacts with the body’s biological systems. Drug action includes various aspects, such as the mechanisms of action and the specific effects produced in the target tissues.

Metabolism refers to the biochemical processes that occur after a drug has entered the body, involving its conversion into different compounds. Side effects are unintended and typically undesired reactions that occur as a secondary response to the drug. Bioavailability describes the extent and rate at which the active ingredient or active moiety is absorbed and becomes available at the site of action, rather than the immediate effects produced upon administration.

Understanding drug action is crucial in pharmacology, as it helps healthcare professionals determine how effective a drug may be and addresses both its intended effects and potential therapeutic outcomes.
