pharmacokinetic - Answer the measured response to time and dose (absorption, blood levels,
mode of inactivation, etc.) This is described as "what the body does to the drug"
pharmacodynamic - Answer the mechanism of action of how drugs produce their effects. This
is often described as "what the drug does to the body"
absorption - Answer being the fraction of an administered dose that reaches the systemic
circulation
distribution - Answer where the drug goes in the body
T ½(half life) - Answer the time required for the serum drug level to decrease by 50%
Metabolism - Answer the way the drug is broken down
Excretion - Answer the way it is cleared from the body
Drug Cycle - Answer deals with the pharmacokinetic variables (Absorption, Distribution,
Metabolism, and Excretion)
bioavailability - Answer the administered dose of unchanged drug that reaches the systemic
circulation
Albumin - Answer only one of many proteins that exist in the blood, but it is the most
abundant, and its size, shape (sort of roundish), and characteristics make it into a binder of
drugs floating in the plasma
The BBB(Blood Brain Barrier) - Answer built into the anatomy of the cerebral circulation
wherein the capillaries of that system are less permeable to some substances, including some
drugs
, liver - Answer main organ for the metabolism of drugs
First Pass Effect - Answer drugs are chemically changed in the liver
metabolite - Answer the active form of the drug
very young or very old - Answer drugs have longer and greater effects due to liver metabolism
issues
tolerance - Answer iver is "pumped-up," (induced) metabolism of the drug is increased and it
takes a lot more drug to produced the same effect
Kidney's - Answer Most drugs are excreted from the body by the....
"Key" - Answer The chemical that binds to the receptor
"Lock" - Answer The receptor
agonist - Answer If the key turns the lock the drug is said to be an
antagonist - Answer If the drug occupies the lock but doesn't "turn it", it is said to be an
Local effects - Answer largely limited to the site of administration and surrounding tissues.
Systemic effects - Answer drug is "felt", to varying degrees, throughout the body (depending
on which tissues the drug receptors are located)
prednisone - Answer A systemic corticosteroid. The organs are exposed along with the skin
Bronchodilators - Answer used to "open" the lungs (local effect), but they can also cause
nervous "jitters" (systemic effect from absorption of some of the drug into the bloodstream)
