DRUGS FOR PAIN AND INFLAMMATION Flashcards
Uses: mild to moderate pain of the skeletal
muscle & joint
➔ NOT addictive & are less potent than
narcotic analgesics
ANALGESICS (NON-OPIOD/NON NARCOTIC)
MOA: act on peripheral nervous system at the pain receptor sites by inhibiting prostaglandin synthesis
ANALGESICS
Effective for dull, throbbing pain of
headache, dysmenorrhea, pain from
inflammation, minor abrasions, muscular pain and mild-moderate arthritis
ANALGESICS
ASPIRIN - a salicylate, oldest non narcotic
analgesic drug
ANALGESICS
CI: children < 12 years old (Reye’s syndrome)
ANALESICS
DI: +warfarin, heparin, thrombolytics = increase bleeding ibuprofen + insulin/OHA =
hypoglycemia
ANALGESICS
SE: gastric irritation, excess bleeding might
occur during the first two days of menstruation
ANALGESICS
Nursing Responsibilities:
➔ take with food
➔ with glass of water
➔ monitor platelet bleeding time PT
➔ d/c aspirin 7 days prior to surgery
ANALGESICS
MOA: weakly inhibits prostaglandin synthesis which decreases pain sensation & heat
ACETAMINOPHEN (TYLENOL, TEMPRA)
Is safe, effective analgesic & antipyretic
drug used for muscular aches & fever caused by viral infections
ACETAMINOPHEN
➔ causes no / little gastric distress; does
not interfere with platelet aggregation, no anti inflammatory effect
ACETAMINOPHEN
CI: severe hepatic / renal disease, alcoholism, hypersensitivity
ACETAMINOPHEN
DI: +caffeine = increase effect +oral
contraceptives, anticholinergics = decrease
effects
ACETAMINOPHEN
SE/ AE: hepatotoxicity, early symptoms of
hepatic damage (N/V, diarrhea & abdominal
pain)
ACETAMINOPHEN
Nursing Considerations:
➔ Liver enzymes,self medications should not
be used for more than 10 days for adults & 5
days for children
➔ keep out of children’s reach
➔ acetylcysteine (antidote)
➔ no alcohol
ACETAMINOPHEN
MOA: binds to opiate receptors in the CNS,
reduces stimuli from sensory nerve end, pain threshold is increased
NARCOTIC ANALGESICS/ OPIOID ANALGESICS
USES:
➔ moderate - severe pain
➔ suppresses pain muscles
➔ suppresses respiratory & coughing by acting on the respiratory & cough centers in the medulla of the brainstem
NARCOTIC ANALGESICS/ OPIOID ANALGESICS
CI: with respiratory dysfunction, head injuries, increase ICP, hepatic and renal disease, alcoholism
NARCOTIC ANALGESICS, OPIOID ANALGESICS
DI: +alcohol, sedatives-hypnotics and other
CNS depressants + increase CNS depression; may increase ALT/ AST
NARCOTIC ANALGESICS/ OPIOID ANALGESICS
SE:
- N/V (particularly in ambulating patients)
- constipation (less in demerol)
- moderate decrease of blood pressure
- orthostatic hypotension (high dose)
- antitussive effect (except demerol)
- CNS: drowsiness, dizziness, confusion,
sedation,
- PUPIL CONSTRICTION - pinpoint pupil - sign of toxicity
NARCOTIC ANALGESICS/ OPIOID ANALGESICS
Codeine: not as potent as morphine
NARCOTIC ANALGESICS/ OPIOID ANALGESICS
Morphine sulfate: potent analgesics (can depress respiration), effective against MI,
dyspnea-pulmonary edema, pre op meds
NARCOTIC ANALGESICS/ OPIOID ANALGESICS
: shorter duration of action than morphine, potency varies according to dosage
MEPERIDINE (DEMEROL)
most commonly used narcotic for
alleviating post op pain, no antitussive property
MEPERIDINE (DEMEROL)
- preferred in pregnancy (does not
diminish uterine contractions & causes less
neonatal respiratory depression) - not prescribed for long term used
MEPERIDINE (DEMEROL)
**withdrawal symptoms called: ABSTINENCE SYNDROME occurs 24-48 hours after last
MEPERIDINE (DEMEROL)
Nursing Considerations:
- VS do not give if RR is < 10/min, BP <
90/70 mmHg
- Administer before pain reaches its peak
to maximize the effectiveness
- Should not taken with alcohol or
sedative -hypnotics
- Check urine output & bowel elimination
- Assist patient in ambulation
- Have naloxone (Narcan) ready as
antidote
- Do not abruptly withdraw medicine
- Assess for toxicity due to overdose
- Instruct about deep breathing &
coughing exercises especially in patients with altered pulmonary function
NARCOTICE ANALGESICS/ OPIOID ANALGESICS
Antidotes for overdoses of narcotic
analgesic
NARCOTIC ANTAGONIST
Have higher affinity to the opiate receptor site than the narcotic being taken
NARCOTIC ANTAGONIST
Blocks the receptor & displaces any narcotic that would be at the receptor, thus
inhibiting the neurotic action
NARCOTIC ANTAGONIST
