Absorption is defined as which of the following?

• A. The process by which medications travel through body tissues to the bloodstream
• B. The breakdown of drugs in the stomach
• C. The elimination of drugs by the kidney
• D. The distribution of drugs to tissues

Answer: (A)

Absorption is the movement of a drug from its site of administration into the bloodstream. It’s how the body first gets exposed to the medication, and it largely determines how quickly and how much of the drug reaches systemic circulation. The description that fits this idea is the process by which medications travel through body tissues to the bloodstream. After absorption, the drug may then be distributed to tissues, metabolized or broken down, and eventually eliminated. The other statements describe later steps: breakdown in the stomach refers to metabolism, elimination by the kidney is excretion, and distribution to tissues occurs after the drug is in the blood.
