1NSAID
non-steroidal anti-inflammatory drug
2NSAIDs MOA
Reversibly inhibit COX-1 & COX-2
Block prostaglandin synthesis
3NSAID uses
-reduce inflammation and pain
4Why are NSAID used in combination with narcotics
Adjunctive therapy; this allows us polong effects of the narcotics thus lowering the use of narcotics
5COX 1
Homestatic functions
6COX 1 gives us the
side effects:
-GI distress
-Renal tract (nephrotoxic)
-platelet function (Bruising and bleeding)
-Macrophage differential (Prone to infections)
7COX-2 gives us the
Gives us the desired outcomes:
-Reduces inflammation

15Caution with Salicylates
NEVER administer to children or teenagers with viral illnesses; can cause Reyes syndrome
16Reyes syndrome
Syndrome which is an acute encephalopathy (inflammation of the brain). Usually follows a viral illness & linked to intake of aspirin. Use acetaminophen (not aspirin) to reduce fever with child with a communicable disease (virus) to prevent this.

39GOUT
painful form of arthritis caused by a buildup of uric acid in the joints, which forms urate crystals
40Four stages of GOUT
1. Asymptomatic hyperuricemia (Uric acid build up in blood)
2. Acute gouty arthritis
3. Intercritical gout
4. Chronic tophaceous gout
41GOUT management
-Weight control
-Regular exercise
-Limiting alcohol, especially beer
-Eating a heart-healthy diet

-Vitamin C
42GOUT treatment
-NSAIDs
-Colchicine (Acute episode, short term)
-Steroids (short term)
May use: Narcotics and non-medicinal
43Chronic GOUT treatment
-Uricosurics (Increases excretion of Uric Acid)
-Xanthine oxidase inhibitors (e.g., allopurinol, febuxostat) *Black box warning*
44Patient teaching GOUT
-Low purine diet
-Vitamin C
-Force fluids
-Assess meds OTC
45Opium
substance derived from the opium poppy from which all narcotic drugs are derived
46Mechanism of Opioids
Agonist, partial agonist, antagonist
47Opioid (agonist)
Mimic the action of endorphins on opiate receptorsin brain
48Opioid Agonist ROA
PO, IV & IM, transdermal, parenteral
49Most abused, illegally used opioid
Oxycodone
50Methadone (agonist)
A treatment that activates opiate receptors slowly than other opiates, dampening the high that addicts get. Eases withdrawal. Used for pain
51Methadone has a ____ half life
Longer
52Morphine (agonist)
narcotic drug derived from opium, used to treat severe pain
53Morphine cautions
-High abuse potential
-Should not be combined with any other sedative or"downer" medication (ie. sleeping pills, tranquilizer
54Fentanyl (agonist)
Opioid Analgesic; Strongest avail. 100x potency of morphine
55Fentanyl ROA
-IV
-transdermal patch
56Fentanyl patient education with Fentanyl patch
-Teach pt. that heat can increase absorption.
- Warn pts not to cut patch in half and do not dispose of patch in trash(flush instead).

67Opiates are mostly...
PRN
68Large doses of Opiates may be required when:

-genetic factors (metabolism)
69Hospital management (Opiods)
-Follow-up assessments to evaluate effectiveness

-Safety measures
-Don't forget to document
70Side effects management (Opioids)
-Often given combined with anti-emetics (5HT3 blockers, promethazine, hydroxyzine)

75Naltrexone (antagonist)
PO as maintenance

-Addiction
78What is drug tolerance?
The phenomenon where an increased dose is required to produce the same effects.
79What happens to drug dosage over time due to tolerance?
The dosage is increased as the body adjusts.
80Identifying drug dependence
When patients uses opioids 10 days or longer, when treatment stops, it causes withdrawal symptoms.
81Drug addiction
A physical or psychological need for higher and higher doses of a drug. Interrupts their daily lives
82REMS
Risk Evaluation and Mitigation Strategy
FDA requirement for drug manufacturers to develop strategies to assure safe use of a specific drug
83Buprenorphine (partial- antagonist)
84Naltrexone
opioid antagonist
85ADR of antagonist opioids
Like any opioid, they are dose dependent, dizzy, drowsy, diaphoresis, respiratory depression, coma → DEATH!
86Opiate addiction treatment
methadone, reduce dose over time, the Relapse rate is sadly high
