A

1906

Gave the government authority to mandate accurate labeling and allowed them to prohibit and penalize the marketing of drugs that were “adulterated or misbranded or poisonous or deleterious”

Problem still existed that compounds could be marked without guarantee of effectiveness or safety

Q

USP and NF

A

The Pharmacopoeia of the USA and National Formulary

Important agencies that set (high) standards for drugs in the US

This is the agency that SETS STANDARDS regarding purity so you take what you believe you are taking in amount and ingredients

Packaging and Quality are also under their jurisdiction so any reliability, changes to packaging, and purity go through the USP

They also make the official drug list

25
Phase I of Drug Testing
Small numbers of HEALTHY volunteers take the medications in few doses and small groups We look at what happens when healthy volunteers take them - college kids and armed service members are often targets for this phase as they are healthier groups
26
Phase II of Drug Testing
Actually give few doses of the medication to the group of interest/treatment, but this group fo interest have either a mild form of the issue or are in the early stages of it with not too many negative problems This is done to find out therapeutic usefulness (!!) and dosages, etc
27
Phase III of Drug Testing
Large studies of thousands of patients trying to glean safety and efficacy of the drug (and see side effects not seen in smaller groups) These are very large and more likely to pick up on adverse issues Double blind and placebo controlled design is used
28
Phase IV of Drug Testing
Approval and post marketing monitoring Follow up once release into the market to uncover other reactions missed now that anyone can take it
29
What are the issues with the Drug Testing Process
1. Limited trials with women and children 2. Adverse effects may not be detected into trials of small numbers 3. Limited post marketing reporting and data
30
Why is the limited amount of women and children in drug testing an issue?
We do not want to work on women who could get or be pregnant nor do people want to sign up their kid for this This leaves older women and giant groups left out
31
Why can adverse effects occur after market release post-drug testing
Adverse effects may not be seen in thousands of people in the testing, but when released to everyone some may begin to show adverse effects and the drug may need to be pulled from market ex: Rezulin worked for diabetes but caused fatal liver disease ex: Redux increased metabolism but gave young women strokes ex:Vioxx was better at stopping arthritis but increased MI and stroke rate - the company was aware of this but left the data out for the FDA!!!!!!!!!!! ex: Viagra - people died in ER due to massive vasdilation and past conditions
32
Why is limited post marketing reporting and data a problem for drug testing
People do not report possible drug related events as often as they should and they may not connect or report adverse effects as being related
33
Chemical Name
precise, chemical composition and molecular structure
34
Generic Name
non proprietary - independent of manufacturer Assigned to indicate pharmacologically related drugs; simpler, but often derived from the chemical name - sometimes there can be variability between sources Used universally, unlike differing trade names
35
Trade Names
brand; proprietary selected by drug company selling it, and is copyrighted; a drug is only marketed by one trade name until the patent expires then, other companies may produce generics that are therapeutically equivalent
36
What may differ between a drug of trade v generic name at the store?
Generic is cheaper and has the active ingredient Trade names are more expensive and may have different coating, flavor, or formulation but have the same active ingredient
37
OTC
Over the Counter Medications May be purchased without a prescription Many drugs have changed over time from prescription only to OTC HUGE Business, but tend to be cheaper
38
The 3 Most Important Drug Characteristics
Effectiveness Safety Selectivity
39
Why may effectiveness be more important than drug safety
Because a drug can be very effective, but have severe side effects such as cancer drugs with significant issues occurring from taking them
40
Selectivity
Referring to a medications ability to only do the thing we want it to do (or as little as possible) We want it doing the thing but not a bunch of other stuff Ex: Anti-infectives will kill organisms but are non-selective and cause GI Issues
41
Components of Drugs
Active Ingredient Additives
42
Active Ingredient
The ingredient giving the drug the desired effect
43
Additives
things added to the drug to make it more appealing Less important in the hospital but in OTC drugs it is very common
44
Vehicles
What carries the drug through the body
45
What are some additives that can be found in a drug
Vehicles Fillers Binders Disintegrators Lubricants Dyes Flavorings Preservatives
46
What are the 3 important things to assess when doing the nursing process in pharmacology
The Patient The Drug The Environment
47
What things might the nurse assess about the patient regarding drugs
Individual pt. variables Age - very young or old have increased intensity and more SE Body mass - wt to ht ratio and looking at composition Inherited factors, Coexisting Conditions, Compliance, Attitude Medical Diagnoses - especially involving liver, kidney, CV Individual Immune System Psychological and Psychiatric Factors Aspects of Self Medications Pregnancy and Lactation OTC Meds
48
Why is compliance and attitude to drugs important to assess
The human brain is the most powerful "drug" and if a person believes that a drug will not work then it will not work for them as well - and the opposite is true
49
Why are medical diagnoses so important to assess regarding drugs
We need to know everything is functioning and if the liver and kidneys still have their abilities to rid the body of waste and drugs
50
Why might psychological and psychiatric factors be so important regarding assessment for drugs
We need to see how it affects adherence and compliance to medication routines, if confusion makes them stop taking their medication, or if they need help
51
OTC is ___ business
big
52
Why is it important to know the OTC drugs a patient takes when assessing the patient?
OTC drugs they take may impact usefulness and safety of other drugs (sometimes they even can remain in the system for 6 months) Same goes for any prescription drugs they take already
53
If a person states they are allergic to a drug, but can take small amounts that dont lead to throat constriction, what may this mean
It was not anaphylaxis but rather just an intolerance You can however also be allrgic to something in the formulation or extra aside from the active ingredient - especially if it is extremely rare for people to be allergic to that specific drug class
54
When assessing a patient it is very important to assess what aspects of their drug history
current meds including prescription and OTC OTC that were taken regularly but have been discontinued within 6 months reactions like "allergies" or "intolerance"
55
Things to Know and Assess regarding the Drug during the Nursing Process
Classification Name Clinical Indication and Contraindications Mechanism of Action Adverse Effects Pharmacokinetics Dosages and Frequency routes Drug Interactions Client Education
56
Outset
Nurse must interpret medication order correctly (confirm with MAR, etc)
57
Standard or Routine Med Orders
Most orders are of this kind ex: Take ___ mg of ___ 3x daily PO
58
PRN Med Orders
Pro Re Nata Mutual discussion (sometimes not always mutual though and up to the nurse) Taken as needed - not regularly scheduled
59
Single Order Med Orders
1 time med order (like before going into surgery)
60
STAT Med Orders
As soon as practically possible Maybe within 20 minutes - not instantaneous
61
Protocol Med Orders
A set of criteria by the institution Ex: Sliding Scale Insulin and BP meds based on BP *ONLY DO IT IF IT IS WRITTEN DOWN NOT JUST "THAT IS THE WAY IT IS"
62
What does it mean to assess the environment during the nursing process
It is a broad definition for anything that is not the drug or the person that will affect the patient It can be resources, facilities, equipment, support persons (like a family member who gives insulin), and nurse practice acts determining what we can and cannot do The larger environment may include institutional policy, professionalism, practice acts, legal standards, and precedents along with various laws and agents - also, the Controlled Substance Act requirements
63
What is important information to gather regarding drugs and the patient in the nursing process
Gather data relative to drug therapy Direct observation, interview with patient, relatives and friends, measure physical parameters - Patient Based Information Review med chart, evaluate lab test, x ray, dx tests, comprehensive health history and med hx - Drug and Patient Information
64
Why interview, observe, and speak to the person regarding their drug information
It can reveal situations such as if they take or do not take their medications and why or why not For example it may reveal opportunities for education
65
Why are physical parameters such important information
The physical parameters can be effected by medications and we need to know whether we want to alter them or if they are safe ex: BP should be taken before giving BP meds, Lasix may lower K levels - double check physicals and lab values
66
Why may health hx be so important to know
If they have a kidney or other issue they may be unable to excrete drugs
67
What are some good sources for drug information
1. Medline Plus - nlm.nih.gov 2. Drug Tests - not every drug will be here though 3. The medical Letter / Prescriber's Letter - very current 4. Online and Cell phone drug information apps like drugs.com, epocrates and other drug handbooks 5. Experts - pharmacists, poison control, pharmaceutical representatives
68
What are not good sources for drug information
Info only from a drug company as they want their drug to sound good and better than it may be Package insert - FDA approval label - No nursing implications and often little action Physicians Desk Reference - for the purpose of nursing this is not helpful
69
Why can the internet be both a good and bad source of information
It can be very good, informational and unbiased, but other information can be company sponsored with bias or incorrect overall. You have to be careful and think critically over what may be what
70
Schedule I Drug
Illegal drugs or use is restricted to research High abuse potential Not accepted for medicinal use in the U.S. (*Marijuana is still included here, though it clearly has some therapeutic uses and is legal for medical and/or recreational purposes in certain states
