Active transport - ANSWER✔✔✨---A process requiring energy for the movement of molecules or
ions AGAINST a concentration gradient, from a region of low concentration to a region of high
concentration.
Affinity - ANSWER✔✔✨---Chemical attraction that impels certain molecules to unite with others to
form complexes.
Agonist - ANSWER✔✔✨---Drug that is capable of binding with receptors to induce a cellular
response.
Antagonist - ANSWER✔✔✨---Drug that blocks the response of another drug.
Bioavailability - ANSWER✔✔✨---Ability of a drug to reach the bloodstream and its target tissues.
Biologics - ANSWER✔✔✨---Substances that produce biologic responses within the body; they are
synthesized by cells of the human body, animal cells, or microorganisms.
Blood-brain barrier - ANSWER✔✔✨---Anatomical structure that prevents certain substances from
gaining access to the brain.
Chemical name - ANSWER✔✔✨---Strict chemical nomenclature used for naming drugs established
by the International Union of Pure and Applied Chemistry (IUPAC).
, Clinical investigation - ANSWER✔✔✨---Second stage of drug testing that involves clinical phase
trials.
Clinical phase trials - ANSWER✔✔✨---Testing of a new drug in selected patients.
Combination drug - ANSWER✔✔✨---Drug product with more than one active generic ingredient.
Complementary and alternative therapies - ANSWER✔✔✨---Treatments that consider the health of
the whole person and promote disease prevention.
Conjugates - ANSWER✔✔✨---Side chains that, during metabolism, make drugs more water soluble
and more easily excreted by the kidney.
Controlled substance - ANSWER✔✔✨---In the United States, a drug whose use is restricted by the
Comprehensive Drug Abuse Prevention and Control Act; in Canada, a drug subject to guidelines outlined
in the Canadian Narcotic Control Act.
Dependence - ANSWER✔✔✨---Strong physiological or psychological need for a substance.
Passive transport - ANSWER✔✔✨---Passive transport is a movement of biochemicals and other
atomic or molecular substances across cell membranes. Unlike active transport, it does not require an
input of chemical energy. The four main kinds of passive transport are diffusion, facilitated diffusion,
filtration and osmosis.
Distribution - ANSWER✔✔✨---The process of transporting drugs through the body.
Drug - ANSWER✔✔✨---General term for any substance capable of producing biologic responses in
the body.
Drug-protein complex - ANSWER✔✔✨---Drug that has bound reversibly to a plasma protein,
particularly albumin, that makes the drug unavailable for distribution to body tissues.
