What term describes what the body does to a drug?

The term that accurately describes what the body does to a drug is pharmacokinetics. This field studies the absorption, distribution, metabolism, and excretion of drugs, providing a comprehensive understanding of how medications move through the body. It encompasses all the processes that affect a drug's concentration over time, influencing its therapeutic effects and potential side effects.

Pharmacodynamics, on the other hand, deals with the effects of drugs on the body and how they exert their therapeutic effects at various receptor sites. Pharmacotherapy refers to the treatment of diseases using medications, while pharmacogenomics examines how an individual's genetic makeup affects their response to drugs. Each of these terms pertains to different aspects of how drugs interact with biological systems, but pharmacokinetics specifically focuses on the body's handling of the drug itself.
