PHARMACOKINETICS AND
PHARMACODYNAMICS FINAL PAPER
2026 EXAM Q AND A STUDY GUIDE
COMPLETE QUESTIONS AND ANSWERS
●● What is pharmacodynamics?
Answer: The study of how a drug produces its effects on the body.
●● Why is understanding pharmacokinetics important?
Answer: Drug dosages are based on 'normal', but disease can alter
physiology and change how a patient responds to drugs.
●● What does A.D.M.E. stand for in pharmacokinetics?
Answer: Absorption, Distribution, Metabolism, Excretion.
●● What is absorption in pharmacokinetics?
Answer: The process by which a drug diffuses or is transferred from
intravascular space to extravascular space (body tissues).
●● Define distribution in pharmacokinetics.
Answer: The movement of a drug throughout the body after absorption.
, ●● What is metabolism in pharmacokinetics?
Answer: The chemical conversion or transformation of drugs into
compounds that are easier to eliminate.
●● What is excretion in pharmacokinetics?
Answer: The elimination of unchanged drug or metabolite from the body
via renal, biliary, or pulmonary processes.
●● What is the therapeutic range of a drug?
Answer: The range of concentration of a drug in a patient's body needed
to achieve beneficial effects without significant side effects (toxicity).
●● What is the maximum effective concentration?
Answer: Above this concentration, signs of toxicity are likely.
●● What is the minimum effective concentration?
Answer: Below this level, concentrations are subtherapeutic and not
effective.
●● What does a narrow therapeutic index indicate?
Answer: The effective dosage is close to the lethal dosage, indicating a
low margin of safety.
