Chapters 1-9 Questions With Complete Solutions
1970 Controlled Substances Act Correct Answers established
"schedules" which are lists of drugs organized according to their
abuse potential
government regulates them than they are controlled substances
1972 FDA "OTC drug Review" Correct Answers over the
counter. no prescription needed, treat minor illnesses
Absorption Correct Answers movement of drug from the site
of administration into the bloodstream
Acute therapy Correct Answers something that is being treated
right now. treated for quick, onset illness
pain medications, inhaler
additive effect Correct Answers combined effect of two drugs
that is equal to the sum of the effects of each drug taken alone.
they both act in similar ways. give low dose of both to get
desired effect
adverse drug reactions Correct Answers unintended but
expected effects of a drug. does not mean mediation has to be
discontinued, possibly add another one to help with side effects
,agonist Correct Answers drug binds to a receptor site,
stimulates a response. agonist drug fits into the keyhole of the
receptor perfectly and causes the body to respond
example: hormone adrenaline lands on your heart and causes the
heart to speed up. there is a drug called epi that mimicks
adrenaline. when injected, it is an agonist that lands on receptor,
heart is going to increase. CREATES RESPONSE
Albumin Correct Answers protein in our blood that some drugs
are attracted to. some drugs are highly protein bond, therefore
people whose blood has a high concentration of albumin will
typically need higher doses of the drug
on the contrary, low albumin levels can lead to toxicity, an
excess of drug being sent to action site
Antagonist Correct Answers drug binds to a receptor, there is
no response. Blocks a response from the body. when an
antagonist fits into the receptor keyhole, it is going to prevent
the body from responding in the way it normally would
example: metoprolol lands on heart receptor. The body's natural
response is to have an increased heart rate. but antagonist
metoprolol is blocking the receptor site so the adrenaline can not
attach to it. It prevents the heart from eliciting a normal
response. BLOCK RESPONSE
Bioavailability Correct Answers A drug that is absorbed from
the intestine must first pass through the liver before it reaches
, the systemic circulation. If a large proportion of a drug is
chemically changed into inactive metabolites in the liver,
then a much smaller amount of drug will pass into the
circulation (i.e., will be bioavailable).
Bioavailability Correct Answers part of the drug that is
unbound and sent to the site of action. unbound=active

chemical composition and molecular structure

mothers need to be aware that all drugs, including herbal ones,

considerations for elderly patients Correct Answers older than
age 65
organs are old and slowing down. start with lower doses because
they can not secrete medication as quickly
average elderly person takes 8-15 drugs a day
