Which of the following phases of pharmacokinetics is described as the removal of the drug or its metabolites through the kidneys, gastrointestinal tract, skin, or lungs?
Correct answer
D
Rationale
The correct answer is D: Excretion. Excretion is the phase of pharmacokinetics where the drug or its metabolites are eliminated from the body through various routes such as kidneys (urine), gastrointestinal tract (feces), skin (sweat), or lungs (exhaled air). This process is crucial for removing the drug from the body and preventing toxic build-up.
A: Distribution is the phase where the drug is transported throughout the body via the bloodstream.
B: Metabolism involves the biotransformation of the drug into its active or inactive metabolites.
C: Absorption is the phase where the drug enters the bloodstream from the site of administration.
In summary, excretion is the correct answer as it specifically refers to the elimination of the drug or its metabolites from the body through various routes.
