COMPLETE EXAM PREP WITH
VERIFIED SOLUTION
✔✔Drug-induced teratogenesis ↪↪The development of congenital anomalies or defects in
the developing fetus caused by the toxic effect of drugs
✔✔Duration of action ↪↪The length of time the concentration of a drug in the blood or
tissues is sufficient to elicit a response
✔✔First-pass effect ↪↪The initial metabolism in the liver of a drug absorbed from the
gastrointestinal tract before the drug reaches systemic circulation through the bloodstream
✔✔Half-life ↪↪In pharmacokinetics, the time required for half of an administered dose of
drug to be eliminated by the body, or the time it takes for the blood level of a drug to be
reduced by 50%; also called "elimination half-life"
✔✔Idiosyncratic reaction ↪↪An abnormal and unexpected response to a medication, other
than an allergic reaction, that is peculiar to an individual patient
✔✔Onset of Action ↪↪The time required for a drug to elicit a therapeutic response after
dosing
✔✔Prodrug ↪↪A parent drug that is not pharmacologically active itself; the prodrug is then
metabolized to pharmacologically active metabolites
, ✔✔Peak effect ↪↪The time required for a drug to reach its maximum therapeutic response
in the body
✔✔Peak level ↪↪The maximum concentration of a drug in the body after administration,
usually measured in a blood sample for therapeutic drug monitoring
✔✔Pharmaceutics ↪↪The science of preparing and dispensing drugs, including dosage
form design
✔✔Pharmacodynamics ↪↪The study of the biochemical and physiologic interactions of
drugs at their sites of activity; examines the physicochemical properties of drug and their
pharmacologic interactions with body receptors
✔✔Pharmacoeconomics ↪↪The study of economic factors impacting the cost of drug
therapy
✔✔Pharmacogenomics ↪↪The study of the influence of genetic factors on drug response,
including the nature of genetic aberrations that result in the absence, over abundance, or
insufficiency of drug-metabolizing enzymes
✔✔Pharmacognosy ↪↪The study of drugs that are obtained from natural plant and animal
sources
✔✔Pharmacokinetics ↪↪The study of what happens to a drug from the time it is put into
the body until the parent drug and all metabolites have left the body; absorption,
distribution, metabolism, excretion
✔✔Pharmacology ↪↪study or science of drugs
✔✔Prodrugs ↪↪An inactive drug dosage form that is converted to an active metabolite by
various biochemical reactions once it is inside the body
