Q

3 Possible Effect of Long Term Use

A
  • TOLERANCE= drug related metabolism problem that causes the same amount of drug to have less effect over time then a higher dose is needed to have same effect.
  • DEPENDENCE= at state in which the body shows withdrawal symptoms when the drug is stopped or a reversing agent is given. Changes in the body either physical or psychological.
  • ADDICTION= psychological and physical dependence in which there is a desperate need to have and use a drug for a non medical reason. The addicted person has a limited ability to control the drug craving or use.

Q

Types of Drug Responses

Chemical reactions that change physiologic activity of body (3)

A

Agonist- Drugs that work by activating or unlocking cell receptors causing the same actions as the body’s own chemicals (produce action similar to our body)

Antagonist- Drugs that attach at a drug receptor site but do not activate or unlock the receptor. Remains inactive. Ex Narcan, reverse drug OD

Partial Agonist- Drugs that attach to the receptor site but produce only partial effect rather than a full effect (Agonist)

Q

Pharmacokinetics
Pharmacon (drug, poison) + Kinetics (motion)

4 basic processes for drug utilization

A

Absorption- Drugs enter the body and pass into circulation to reach the part of the body it needs to affect through the processes of diffusion, osmosis, and filtration. Influences that effect absorption: solubility, route, blood flow.

Distribution- Movement of a drug in the body to reach it’s site of action by way of the blood and lymph system

Metabolism- once the drug is absorbed and distributed in the body the body transforms or alters the drug into active or inactive chemicals. Liver 1st pass= inactivates. Med is broken down and used in chemical reactions- Biotransformation

Excretion or Elimination (kidneys) - All inactive chemicals, and chemical bi-products and waste (often to referred to as metabolites) finally break down through metabolism and are removed from the body through of processes of excretion.

Half-Life- The time is takes the body to metabolize and excrete 50% of the drug from the body. Short 1/2 life= take drug more often. Long 1/2 life= may take med 1x/day

Common Drug Interactions Additive Effect Antagonistic Effect Displacement
Additive Effect = 2 drugs given together, work as a team. ex: calcium w/ vit D Antagonistic Effect = 1 drug interferes with the action of another ex: narcan Displacement = One drug replaces another at the drug receptor site, decreasing the effect of the first drug ex: displace effects of a sedative
26
Common Drug Interactions Incompatibility Interference Synergistic Effect
Incompatibility = Drugs mixed together produces a chemical reaction. (do not mix well) Interference = Second drug causes the rapid excretion of another decreasing the effect of the first one Synergistic Effect = 2 drugs given together have a greater effect than if they were given separately. Example- Tylenol is given with codeine for added pain relief
27
Patient Variables: Affect on Drug Action
``` Body Weight Age Illness- liver/kidney problems Food, alcohol, drugs Pregnancy and breastfeeding- risk vs benefit Genetics Cumulative Effects- increased side effects Psychological Dependence ```
28
``` FDA Pregnancy Risk Categories A B C D X ```
A - No demonstrated risk to human fetus B- No demonstrated risk to fetus in animals but data is lacking for humans C- Teratogenic effects in animals; no data for humans D- Evidence of human fetal risk but benefits may outweigh the risk for pregnant women X- Demonstrated risk to fetus. The use of the product is contraindicated in pregnant women
29
Types of Drug orders | STANDING
Standing= indicates the drug is to be given until discontinued or for a certain amount of doses. Hospital or institutional policy usually dictates that most standing orders expire after a certain number of days. A renewal order must be written by a prescriber before the drug may be continued.
30
Types of Drug orders | EMERGENCY OR STAT
Emergency or STAT= one time order to be given immediately
31
Types of Drug orders | SINGLE
Single= a one time order, given at a specified time
32
Types of Drug orders | AS NEEDED OR PRN
As needed or PRN= is an order for a drug to be given as needed based on nurse's judgement of safety and patients need
33
Define Absorption
Drugs enter the body and pass into circulation to reach the part of the body it needs to affect through the processes of diffusion, osmosis, and filtration.
34
Define Adverse effect/reaction
Severe symptoms or problems that can cause great harm
35
Define Agonist
Drugs that work by activiating or unlocking cell receptors causing the same actions as the body's own chemicals.
36
Define allergy
An antigen-antibody response that can cause hives, rashes, itching, or swelling
37
Define Anaphylactic reaction
A serve life threatening form of an allergic reaction
38
Define antagonist
Drugs that attach at a drug receptor site but do not activate or unlock the receptor
39
Define Brand name
CAPITALIZED- The proprietary name that a manufacturer gives to a specific drug. AKA trade name
40
Define Desired action
The drug does what it supposed to do
41
Define Distribution
Movement of a drug in the body to reach it's site of action by way of the blood and lymph system
42
Define First-pass effect
drugs move very quickly from the stomach or SI to the liver. drugs are inactivated in the liver before being distributed to other parts of the body. that is why some drugs are given sublingual or IV or it would be inactive and pt. wouldn't receive the amount of drug they require.
43
Define Idiosyncratic response
Responses to a drug that are peculiar and unpredicated
44
Define nephrotoxic
Adverse drug effects that can result in kidney damage
45
Define pharmacodynamics
The effects of a drug on a body function (what a drug does to the body)
46
Define pharmacokinetics
The metabolism of a drug within the body (what the body does to a drug)
47
Define pharmacotherapeurtics
The use of drugs in the treatment of disease
48
Define side effect
Mild but annoying responses to the drug. Nausea and headache are common and usual side effects to many drugs
49
Define generic name
NOT CAPITALIZED- The most common drug name used the manufacturer in all countries. AKA non proprietary name.
50
Define half life
The time is takes the body to metabolize and excrete 50% of the drug from the body
51
Define synergistic effect
The effect of two drugs taken at the same time is greater than the sum of the effects of each drug given alone
52
Define trade name
CAPITALIZED- The propriety name that a manufacturer gives a specific drug. AKA brand name.
53
``` Types of excretion and elimination FECES URINE BREATHING EVAPORATION OTHER ```
Feces- fibrous or insoluble waste usually passed through GI tract as feces. Urine- chemicals that may be made of water-soluble are dissolved and filtered out as they pass through kidney and are lost in urine Breathing- some chemicals are exhaled from the lungs through breathing Evaporation- lost through evaporation through the skin during sweating Other- very small amounts of drug escape in tears, saliva, tears and breast milk
54
Common Responses to Meds | DESIRED/ THERAPEUTIC EFFECT
The expected response of a drug and the therapeutic goals is reached. IE- fentanyl patch relieves pain.
55
Common Responses to Meds | SIDE EFFECTS
Mild but annoying responses to the drug. Nausea and headache are common and usual side effects to many drugs. May not nec. change the med (stomach pain due to ASA)
56
Common Responses to Meds | ADVERSE EFFECT OR REACTION
Severe symptoms or problems that can cause great harm. Ex GI bleed from ASA. May develop SS. Let provider know, may change or stop med.
57
Common Responses to Meds | IDIOSYNCRATIC RESPONSE
Responses to a drug that are peculiar and unpredictable. IE- genetic or hormonal variation of that individual.
58
Common Responses to Meds | PARADOXICAL REACTION
patients reaction may be just the opposite reaction than what is expected. IE- benadryl is a sedation but will cause excitement and awareness.
59

Category of drugs regulated by federal legislation because they are dangerous and their use must be controlled; may be purchased only when prescribed. antibiotics etc. Medicare controls price to be charged
63
Categories of drugs (Defined by Fed gov) | Over the counter
Category of drugs identified by federal legislation as having low risk to patient and may be purchased without a prescription. Ex tylenol. Herbal meds- not tested for safety and effectiveness and can interact with meds
