SOLUTION!!
generic name - (ANSWER)not capitalized, less expensive
brand name - (ANSWER)commercial name, capitalized
what are the different types of oral medications? - (ANSWER)liquid, tablet, capsule, powder
which form absorbs the fastest? - (ANSWER)liquid
which form absorbs the slowest? - (ANSWER)enteric coated tablet
what are the 3 ways a drug can be delivered parenterally? - (ANSWER)intravenously, subcutaneously,
intramuscularly
which parenteral drug is fastest? - (ANSWER)IV
pharmacokinetics - (ANSWER)movement of drugs from site of administration to various tissues
1st pass effect - (ANSWER)some of the drugs when passed though the liver may deactivate —> reduces
effect of drugs
bioavailability - (ANSWER)amount of oral drug after passing through the liver
parenteral drugs - (ANSWER)does not get affected by 1st pass effect because it goes directly to the vein
or tissue
what factors affect distribution to different parts of the body? - (ANSWER)-movement of drug by
circulatory system to intended site of action
-drugs enter the blood after they absorb through intestinal wall or alveoli in lungs or after direct/indirect
injection

SOLUTION!!
-liver, heart, kidneys receive most of drugs because of their rich drug supply
-bones or areas with natural barrier (brain) won't receive as much of the drug
Metabolism (biotransformation) - (ANSWER)The biochemical alteration of a drug into an inactive
metabolite, a more soluble compound, a more potent active metabolite, or a less active metabolite
biotransformation - (ANSWER)when a drug is chemically altered during metabolism
Where does metabolism take place? - (ANSWER)liver
half life - (ANSWER)time it takes for a drug that enters the body to decrease in half
onset - (ANSWER)the time it takes for the drug to elicit a therapeutic response
peak - (ANSWER)The time it takes for a drug to reach its maximum therapeutic response
duration - (ANSWER)time the drug lasts without additional doses
peak level - (ANSWER)The maximum concentration of a drug in the body after administration, usually
measured in a blood sample for therapeutic drug monitoring.
trough level - (ANSWER)The lowest concentration of drug reached in the body after it falls from its peak
level, usually measured in a blood sample for therapeutic drug monitoring.
Why is peak & trough important? - (ANSWER)must maintain at a therapeutic level in the blood in order
to be effective
Pharmacodynamics - (ANSWER)Biochemical changes that occur in the body as a result of taking a drug
