Pharmacokinetics describes

Pharmacokinetics describes

• A. How the body processes the drug (ADME)
• B. The drug's mechanism of action
• C. The drug's therapeutic class
• D. The drug's side effects

Answer: (A)

Pharmacokinetics describes how the body handles a drug through absorption, distribution, metabolism, and excretion (ADME). This determines the drug’s concentration in the blood over time, which drives onset, intensity, duration, and dosing intervals. It explains how factors like the route of administration, formulation, organ function, and drug interactions alter exposure and clearance. In contrast, pharmacodynamics is about what the drug does to the body—the mechanism of action and the resulting effects at the target site. Therefore, describing the body's processing of the drug (ADME) best captures pharmacokinetics.
