and Answers 100% Pass Solution A
Graded
Absorption - ANSWER>>the process by which drug molecules
move from their site of administration to the blood
Affinity - ANSWER>>the ability of some tissues to attract,
accumulate and store drugs in high concentrations relative to
other tissues
blood-brain barrier - ANSWER>>Blood vessels (capillaries) that
selectively let certain substances enter the brain tissue and keep
other substances out
diffusion - ANSWER>>process by which molecules tend to move
from an area where they are more concentrated to an area where
they are less concentrated
distribution - ANSWER>>the transport of drugs throughout the
body after they are absorbed
drug-protein complexes - ANSWER>>formed when a drugh that
binds reversibly to a plasma protein, particularly albumin, that
makes the drug unavailable for distribution to its site of action
enterohepatic recirculation - ANSWER>>recycling of drugs and
, other substances by the circulation of bile through the intestine
and liver
enzyme induction - ANSWER>>process by whick a drug
increases the activity of the hepatic microsomal enzymes
excretion - ANSWER>>the process of removing substances from
the body
first-pass effect - ANSWER>>mechanism whereby drugs are
absorbed enter into the hepatic portal circulation and are
inactivated by the liver before they reach the general circulation
fetal-placental barrier - ANSWER>>special anatomic barrier that
inhibits many chemicals and drugs from entering the fetus
hepatic microsomal enzyme system - ANSWER>>as it relates to
phamacotherapy, liver enzymes that metabolize drugs as well as
nutrients and other endogenous substances, sometimes called
the P-450 System
isozymes - ANSWER>>multiple similar forms of an enzyme that
perform slightly different metabolic functions
loading dose - ANSWER>>relatively large dose of a drug given at
the beginning of treatment to rapidly obtain a therapeutic
response
