Which term describes the procedure for drug elimination typically involving the kidneys?

The term that describes the procedure for drug elimination typically involving the kidneys is excretion. This process is essential for removing waste and excess substances from the body, ensuring that the blood and bodily fluids maintain proper chemical balance. During excretion, the kidneys filter out metabolites and drugs from the bloodstream, allowing them to be eliminated through urine. This physiological function plays a critical role in pharmacokinetics, as it directly affects the duration and intensity of a drug's action in the body.

In contrast, absorption refers to the process through which a drug enters the bloodstream after administration. Distribution describes how the drug is dispersed throughout the body's tissues. Metabolism involves the biochemical modification of the drug, often in the liver, transforming it into forms that are easier for the body to excrete. Understanding these processes is crucial for comprehending how drugs function within the body and how their prolongation or reduction can affect therapeutic outcomes.
