Q

Why should PTs study pharmacology

A

We need to know how our patients respond to drugs and we need to plan our treatments times accordingly

Q

What sort of questions should come to mind when thinking about how the patient might respond to drugs

Q

Pharmacology is a good news/bad news subject. Explain why pharmacology is both good and bad

A

It is good because new drug therapies are improving quality of life and outcomes, but it is bad because healthcare professionals cannot stay on top of the rapidly changing discipline

Q

How does knowledge of pharmacology effect the physical therapy profession?

A

We have an expectation to be experts of medical awareness and an obligation to address all aspects of patient signs and symptoms. With that comes the responsibility of maintaining a current knowledge base

Q

Where does pharmacology fit in the patient/client management model

A

During the examination you find out the type of medication the patient is on and during the evaluation process you begin to think how those medications are effecting the patient/treatment

Q

What do we need to be aware of when working with patient’s on beta blockers

27
Grapefruit juice interferes with the metabolism of (beta/calcium channel) blockers in the stomach
calcium channel
28
True or False: For a patient on beta blockers, we should use their HRmax to determine the level of appropriate exercise
False, we should use their RPE
29
What are the three effects that drugs can have
1. Therapeutic effect 2. Side or adverse effect 3. Toxic effect
30
What type of effect would a drug have that is intended and desired
therapeutic effect
31
What type of effect would a drug have that is unintended or has an unwanted effect at normal dosage
side effect or adverse effect
32
What type of effect would a drug have if its harmful or life threatening
toxic
33
What are the three types of drug nomenclatures
chemical, generic, and trade or brand name
34
What is another name for the drug trade or brand nomenclature
proprietary
35
Which drug nomenclature is the specific chemical structure
chemical
36
N-Acetyl-p-aminophenol is the _____ nomenclature
chemical
37
Which drug nomenclature is the nonproprietary official name that is derived from the chemical name
generic
38
acetaminophen is the _____ nomenclature
generic
39
Which drug nomenclature is the name that is assigned by the pharmaceutical company
trade or brand name
40
Tylenol is the _____ nomenclature
trade/brand or proprietary
41
Generic drug names are the same as trade drug names but off patent and has been show to be ______.
bioequivalent
42
What does bioequivalent mean
All active ingredients are the same in a generic drug compared to a trade name drug
43
Even though generic and trade name drugs are _____, they are also different in the pharmacokinetics and pharmacodynamics. List the three ways that generic/trade name drugs are different
bioequivalent; 1. Preservatives may be different 2. Particle size may be different 3. Prices are different
44
Does generic or trade names cost less and why
Generic drugs cost much less because trade name pharmaceutical companies paid to put their name on the medication
45
True or False: Cheaper generic drugs are always better than the trade name drug since generic drugs are often listed first on insurance plans
False. Even though generic names might be listed first on insurance plans, cheaper is not always better.

47
Can PTs prescribed prescription drugs
no

62
Preclinical studies are tested on (humans/animals)
animals
63
The (closer/further) apart an effective dose and a toxic dose are, the better and safer a drug is

4
66
Describe phase one of a clinical human study
A small number of volunteers (less than 100) are studied to determine effects, pharmacokinetics and safe dosages for less than a year
67
Describe phase two of a clinical human study
assess drug's effects on a specific disease with 200-300 subjects for about 2 years
68

a range of doses which actually causes an effect in a patient or population
72
True or False: A dose can be so low it causes no response
true
73
As a dose is increased, it should have (more/less) effect
more
74
True or False: Eventually, after increasing a dosage so much it will no longer produce an effect
true
75
What is the ceiling effect
The point at which increasing a dose will have no increasing effects on the body/symptoms
76
If a drug is more potent, will it require a lower or higher dosage to produce an effect
lower
77
True or False: If a drug is more potent, the efficacy will be higher
False, a more potent drug could come on faster, but not last as long
78
What is the formula of finding the therapeutic index (TI)
