ANSWERS

drug - CORRECT-ANSWERSany chemical that affects the physiologic process

pharmaceutics - CORRECT-ANSWERSthe study of how various dosage forms
influence the way in which the drug effects the body
pharmacokinetics - CORRECT-ANSWERSthe study of what the body does to a
drug
pharmacodynamics - CORRECT-ANSWERSthe study of what a drug does to
the body
absorption - CORRECT-ANSWERSmovement of a drug from its site of
administration into the bloodstream
distribution - CORRECT-ANSWERStransport of a drug by the bloodstream to
its site of action
metabolism - CORRECT-ANSWERSbiochemical alteration of a drug into a
metabolite
cytochrome P-450 - CORRECT-ANSWERSlarge class of enzymes that play a
significant role in drug metabolism and drug interactions
bioavailability - CORRECT-ANSWERShow much of the drug is absorbed into

excretion - CORRECT-ANSWERSdescribes the elimination of the drug from
