Opioid And Non-opioid Medications Flashcards
Physical component of pain
Nerve pathways and brain
Psychological component of pain
Anxiety
Previous pain experience
Age
Sex
Culture
Acute pain
6 mo or less
Sudden onset
Subsides with treatment
Chronic pain
6 mo or more
Persistent or recurring pain
Difficult to treat
Visceral pain
Organ pain
May be referred pain
Ex: left arm pain from a MI
Somatic pain
Muscular skeletal
Localized, constant
Aching or throbbing
Neuropathic pain
Ex: sciatica
Peripheral nerve injury
Pain is called paresthesia
* described as burning, SHOOTING, and tingling
Break through pain
Pain that breaks thru med effective window
Three main classes of opioid receptors
Mu Receptors
Kappa Receptors
Delta Receptors
Mu Receptors
Most important
Response to these being stimulated is analgesia, resp depression, euphoria, and sedation
Physical dependence
Becoming so use to it that your body relys on it
Kappa receptors
Can produce analgesia and sedation
Delta receptors
the opioid analgesics do not affect these
Agonist
“to do”
binds with a receptor to produce a maximum response
partial agonist
produces a partial response
antagonist
“to block”
Agonist opioid analgesics
Morphine
Considered the “benchmark” med of this classification
*We use it to see how effective our Mu receptors are
Morphine
Produces effects by combining with mu recptor sites
Morphine indications
Severe pain
Cardiac pts (has vasodilatation properties, helps decrease workload of heart and increase the oxygen available)
Cough suppression (in low doses) (low dose morphine)
*works by depressing the cough center in brain
*wont work cough r/t post nasal drip
* for coughs due to pressure on the cough center of brain
Morphine administration
Oral
IM (discharge dose)
IV (mainly)
SQ
Epidural
Intrathecal
Rectal
How is fetanyl usually given
Patch
Mu receptor opioid agonists
Adverse Reactions
Seizures (with OD)
Pruritus
Skin rash
**Facial edema/angioedema
**Respiratory depression
Confusion
Tachycardia
Opioid agonist
Side Effects
Dizziness
Faintness
Lightheadedness
Fatigue
sleepiness
N/V
increased sweating
constipation
hypotension
*some level of sedation is common
moderate to strong opioid agonists
codeine (found in tylenol #3)
*mix of tylenol and codeine
hydrocodone (lortab, vicodin, vicoprofen)
*combination meds
oxycodone (percodan, percocet)
