Correct | EKU
Pharmacology - ANSWERS Study of drugs and drug actions
Pharmacodynamics - ANSWERS what the drug does in the body-or to the
target cell
Receptors - ANSWERS Protiens located on the surgaces of the cell membranes
or w/in cells. "the lock"
When drug molecules bind with receptors molecules - ANSWERS the resulting
drug-receptor complex initiates a physio-chemical reaction that stimulates or
inhibits it's normal cell function
Agonist - ANSWERS drugs that produce effects similar to those produced by
naturally occurring hormones, neurotransmitters, and other natural substances.
Antagonist - ANSWERS drugs that inhibit cell fx by occupying receptor sites
Therapeutic Index - ANSWERS The relationship between a drugs desired
therapeutic effects and its adverse effects
, Wide therapeutic index - ANSWERS drug is safe, close monitoring not required
Narrow therapeutic index - ANSWERS Amount of drug required for
therapeutic effect is not much different that the amount of drug producing a toxic
effect. < 2. Close monitoring needed.
Minimal effective Concentration - ANSWERS The minimal blood level at which
the drug exerts the desired effect
Area under the curve - ANSWERS plot of the plasma concentration vs. time
after a single dose of drug is administered
T-max - ANSWERS time to maximum (peak) drug level after a drug is
administered
C-max - ANSWERS maximum (peak) concentration of a drug after it is
administered
First-Pass effect - ANSWERS Some drugs, when passing from the intestines to
the liver, get metabolized with only part of drug dose reaching systemic circulation
for distribution
Bio-availability - ANSWERS % of drug that reaches systemic circulation after an
administered dose. Used to determine drug dose.
Potency - ANSWERS a relative measure that compares the doses of 2 different
drugs that are required to achieve the same effect
