Which ADME process describes the movement of a drug throughout the body?

Distribution refers to how a drug moves from the bloodstream into tissues and organs after it enters systemic circulation. It explains how the drug travels to its sites of action, storage sites, and eventual elimination, and is influenced by factors like blood flow to tissues, capillary permeability, and the drug’s properties (lipophilicity, ionization, and protein binding). This is distinct from absorption (entry of the drug into the blood from the administration site), metabolism (enzymatic chemical changes to the drug), and excretion (removal from the body). So, the process describing movement throughout the body is distribution.
