phases of pharmacokinetics Correct Answer - 1. Absorption 2. Distribution 3. Metabolism 4. Excretion Absorption Correct Answer - The transmission of medications from the location of administration to the bloodstream. Rate of absorption determines how soon the medication will take effect. The amount of medication the body absorbs determines the intensity of its effects. The route of administration affects the rate and amount of absorption.
