receptors Ans: site which forms a bond with a particular
Guru01 - Stuvia
drug, usually forms when the drug and the receptor have the
Expert
same shape and a chemical affinity for one another
pharmacodynamics Ans: the study of the interactions
between a drug and its receptor, as well as the ensuing
pharmacologic response
pharmacologic response Ans: effect of the drug, depends
upon the perfection of the fit between the receptor and the
drug (most drugs have several atoms within each molecule that
fit within the receptor) as well as the number of receptor sites
that are occupied.
agonists Ans: drugs that interact with a receptor to stimulate
a response
antagonists Ans: drugs that attach to a receptor site but do
not stimulate a response
partial agonists Ans: drugs that interact with a receptor to
stimulate a response but inhibit other responses
, 2
most common routes of drug administration Ans: enteral,
parenteral,
enteral Ans: route of drug administration which directly
enters the GI tract; either oral, rectal, or nasogastric
parenteral Ans: route of drug administration which bypasses
the GI tract; either subcutaneous, intramuscular, or
intravenous injection

percutaneous Ans: route of drug administration that involves
absorption through the skin or mucus membranes; either
inhalation, sublingual, or topical
Guru01 - Stuvia
Expert
pharmacokinetics Ans: the study of the mathematical
relationships among the ADME features of individual
medicines over time
ADME Ans: after liberation, the five steps each individual
drug goes through within the body (absorption, distribution,
metabolism, and excretion)
liberation Ans: release of a drug from its dosage form and the
process of dissolving into bodily fluids (i.e., a tablet
disintegrating and dissolving within GI fluids)
absorption Ans: process whereby a drug is transferred from
its site of entry into the body to the circulating fluids of the
body (i.e., blood, lymph)
factors influencing the rate of absorption Ans: route of
administration, blood flow through the tissue where the drug
is administered, and the solubility of the drug
