30
Define "OTC drugs"
"Over The Counter" drugs, do not require an Rx
31
List the 4 different names a drug can have:
chemical, generic, international, trade
32
What is a drug's chemical name?
describes the chemical composition of the drug and is assigned using the standard nomenclature established by the IUPAC-a drug has only ONE chemical name
33
What is a drug's generic name?
less complicated and easier to remember than the chemical name. Each drug has ONE generic name in the USA, can have a different international generic name.
34
What is a drug's trade name?
assigned by the company marketing the drug. "brand" name. Each drug may have SEVERAL trade names.
35
N-acetyl-para-aminophenol is an example of a ______________ name
chemical
36
Tylenol is an example of a ___________ name
trade
37
acetaminophen (USA) or paracetamol (IN) are examples of ____________ names
generic
38
Define pharmacology:
the study of substances that interact with living organisms to produce a biologic response
39
List the 4 principles of pharmacology:
1. pharmaceutical 2. pharmacokinetic 3. pharmacodynamic 4. pharmacotherapeutics
40
Define pharmaceutical:
refers to a group of interdisciplinary studies of a drug
41
Define pharmacokinetic:
how the BODY reacts TO the DRUG/ how the drug moves through the body *kinetic-body moves-how the body effects the drug
42
Define Pharmacodynamic:
the effect of the drug on the body **dynamic=the body can produce a dynamic range of effects on the body
43
Define absorption:
the reate at which a drug leaves its original site (sie of administration)
44
Define distibution:
the transfer of the drug throughout the body
45
What are some things that can hinder drug distribution?
the blood-brain barrier, fat soluable, protein binding
46
Define metabolism as it relates to a drug:
The biochemical transformation of the drug-how it is broken down
47
Which organ is especially important for drug metabolism?
The liver
48
Define excretion as it relates to drugs:
how the drug leaves the body
49
What is the primary organ involved in drug excretion?
The kidney, but intestinal tract and liver also play a role
50
Absorption, distribution, metabolsim and excretion are all examples of drug__________
pharmacokinetics
51
The mechanism of action, effects, and drug receptor interaction are all pieces of ____________
pharmacodynamics
52
What are side effects?
Effects of a drug other than what is targeted. Can be positive or negative.
53
What are adverse effects?
Refers to negative effects of a drug, can be fatal, not good!
54
What does drug receptor interation refer to?
In order for a drug to work, it must fit into the proper receptor site on a cell-if not it will not bind, and will not work
55
What is a patient's functional state?
Refers to the state of the patient BEFORE medication is administered
56
What does pharmacotheraputics refer to?
the effectiveness and safety of a drug
57
What is a dose response?
The pt's response to a certain drug dose-varies from pt to pt and can depend on what disease state/stage they are in
58
A thereaputic range refers to:
The lowest and highest levels of a drug in the blood
59
Define peak:
The highest level of a drug in the blood
60
Define trough:
The lowest level of a drug in the blood
61

62
Define lethal dose:
A dose of a drug that is too high, can be fatal
63
Define drug 1/2 life:
The time required for drug's plasma concentration to be reduced by half (time it takes for 1/2 of original dose to leave the body)
64
Define loading dose:
An initial higher dose of a drug given to a pt
65
Define maitenance dose:
dose required to keep a steady theraputic level of drug in the bloodstream
66
How many half lifes does it take to achieve a "steady state" of a drug?
4 to 5
67
What is baseline data?
pre-drug administration data for a pt
68
Being aware of the side effects of a drug and how to intervene if necessary is also called___________
stratification of risk
69
What are the 5 rights of drug administration?
Right: Patient, Drug, Dose, Route, Time
70
Cells function normally when they are in a ______________ state
homeostatic
71
Excess physiologic or pathologic stress may force cells into an ___________ state
adaptation
72
Too much stress that exceeds the cell's adaptive capacity can lead to cell ___________
injury
73
T or F: Cell injury can be reversible or irreversible.
TRUE
74
Cell death is a direct response of ___________
irreversible injury
75
Define Hypoxia:
lack of oxygen to cells
76
What is the #1 cause of cell injury?
hypoxia
77
Define necrosis:
eschemic-lack of blood flow-without blood flow cells die
78
Define atrophy:
cell is shrunken, looses its integrity and cell membrane
79
Define hypertrophy:
cell is overgrown, too large
80
Define hyperplasia:
rate of cell division has increased, BAD
81
Define metaplasia:
ALWAYS bad. Cells are multiplying too fast AND changing shape
82
Define dysplasia:
cells grow disorganized, go in different directions, but still the same original shape (hyperplasia can lead to dysplasia)
83

in response to changes in environment and for protection and social control
84
Karyolysis and pyknosis are two examples of ____________
cellular injury related to the DNA/nucleus
