Absorption is best described as

• A. How the drug gets to the body
• B. How the drug is distributed in tissues
• C. How the drug is metabolized
• D. How the drug is eliminated

Answer: (A)

Absorption is the movement of a drug from its site of administration into the bloodstream, so it’s about how the drug enters the body and becomes available to produce an effect. This step sets how quickly and how much of the drug reaches systemic circulation, which drives onset and intensity of action. It’s distinct from distribution (how the drug spreads from blood into tissues), metabolism (chemical transformation by the body), and elimination (removal from the body). So describing absorption as how the drug gets to the body captures the initial entry into the bloodstream and availability for action.
