Chapter 11 Vocab Flashcards
Absorption
Process where meds move from administration cite to vascular system
Adrenergic
pertaining to nerves that release neurotransmitter norepinephrine and receptor sites that it acts upon
Affinity
measure of attraction between drug and receptor site
Agonists
drugs that bind to receptor and cause response in parasympathetic NS
Analgesics
a pain reliever
Antagonists
drugs that bind to receptor sites and prevent a normal response by cell
Anticholinergics
drugs that block acetylcholine receptors, preventing transmission of parasympathetic nerve impulses
Anticoagulant
med that prevents blood clotting
Antiplatelet
med that interferes with platelet aggregation
Barbiturates
sedative that increases affinity between receptor sites and neurotransmitter GABA
Bioavailability
degree to which drug becomes available at physiological site of administration
Biotransformation
chemical alterations that a substance (drug), undergoes in the body
Cholinergics
meds that stimulate cellular acetylcholine receptors
Contraindications
condition under which a medication would harm the patient
Cross-tolerance
decreases of effectiveness of several related drugs
Diuretic
substance that promotes excretion of water through kidneys
Fibrinolytic
substance that breaks down blood clots by initiating body’s normal mechanism for dissolving blood clots
Habituation
tolerance to drug after repeated doses
Half-life
time it takes for the level of a drug to decrease by 50%
Hypersensitivity
allergy
Iatrogenic
adverse condition from provided medical treatment
Idiosyncratic reaction
unusual, unexpected reaction to med
Indications
conditions that must be present from proper administration of drug
Mechanism of action
the way that a drug has its therapeutic effect on body
Nonsteroidal anti-inflammatory
meds with pain-relieving and fever-reducing properties that decrease inflammatory response
Over-the-counter medication
any drug that can be purchase without perscription
Parasympatholytics
med that reduces action of parasympathetic nervous system
Parasympathomimetics
type of meds that are agonists to parasympathetic nervous system
Pharmacodynamics
actions that drugs have on the body
Pharmacokinetics
branch of pharmacology the deals with the way drugs are absorbed, distributed, metabolized, and eliminated from body
Pharmacology
study of the origin, nature, properties, and actions of drugs and their effects
Potentiation
enhancement of a drug from being combined with another
Sympatholytics
Sympathomimetics
Synergism
combination action of two drugs together, where the effect is greater than the sum of the individual effects of the two drugs
Teratogenic
med that when taken by pregnant woman, may deform, injure, or kill the fetus
Therapeutic index
ration that compares a meds lethal does in 50% of the population, to an safe, effective dose in 50% of the population. The closer the ratio to 1:1, the less difference between lethal and correct dosages
Therapeutic threshold
amount of medication that must be in blood stream to begin to have an effect
Tolerance
decrease in effectiveness of drug due to prolonged use
Sympathomimetics
classification of meds that mimic affects pf sympathetic NS
