QuestionAnswer
drug form same as drug preparation
transdermal patch providing constant, even flow of drug over a period of time
cap capsule
IM intramuscular
IV intravenous
IVPB intravenous piggyback
route of delivery most suited means of absorption for intended use
subq subcutaneous
R rectal
PO oral, by mouth
tab tablet
susp suspension
supp suppository
gtt drop
elix elixir
parenteral any route not involving the GI tract
capsule drug contained within a gel type container
enteric coated special coating that resists disintegration by gastric juices
time release delivers a dose of drugs over an extended period of time
tablet disk of the compressed drug
lozenge often have a soothing effect on the throat
suspension liquid form that must be shaken well; the drug is not evenly dissolved in the liquid
emulsion liquid form that contains fats and oils in water
elixir contains an alcohol base
syrup sweetened liquid, common for giving to children
solution liquid in which the drug is evenly dissolved, appearance is clear
suppository is inserted into the rectum, melts at body temperature
enema solution drug is suspended in a solution solely for enema purpose
injectable drug forms solution and powder
intravaneous injected directly into a vein; absorption is immediate
intramuscular injected into a muscle; absorption is rapid
subcutaneous injected into the fatty tissue below the skin, slower absorption
intradermal injected just beneath the skin, as in allegy skin testing
epidural injected into a catheter that has been placed in the spinal canal
intracardiac injected directly into the heart
intraspinal injected directly into the subarachnoid space, containing cerebrospinal fluid
intracapsular injected into the capsule of a joint, to reduce inflammation
mucosal drug forms eye, ear, nose drops; eye ointment; vaginal cremes; rectal and vaginal suppositories; douche solutions; buccal tablet; sublingual tablet

intrathecal used to administer drugs within the meninges around the spinal cord
intra-arterial used to administer chemotherapy directly into the area of cancer, can be worn externally
pharmacokinetics the study of how drugs move through the body in the processes of absorption, distribution, metabolism, excretion
barriers to drug distribution blood-brain barrier; placental barrier; selective distribution
excretion or elimnation respiration, perspiration, urination, defecation
half-life the time it takes for half of the drug to be eliminated from the body; determines how frequently a drug should be taken
agonist drugs when a drug displays an affinity or attraction for a receptor and stimulates it; drug that mimics body function
antagonist drugs a drug that has an affinity for a receptor but displays no intrinsic activity
synergist one drug potentiates another drug
receptor site where drugs will attach, the better the fit of the drug the better the expected response
competitive antagonist competes with the agonist for receptor sites, larger doses of the agonist can overcome the antagonist effects
noncompetitive antagonist binds to the receptor site and blocks the effects of the agonist, larger doses of the agonist can't reverse its action
types of receptors adrenergic, cholineric, H1 and H2
contraindication absolutely should not be given
idiopathic unknown
paradoxical opposite of the expected result
idiosyncrasy unique, unusual response for a drug
