When deciding which analgesic agent to use for a patient in pain, there are several patient and drug characteristics that should be considered. Name 5?
- SE
- Allergy
- Co-morbid disorders
- Tolerance
- Previous agents used
True or False - typically there is no pathology present for patients in chronic malignant pain?

True or False - there is profound psychological effects for both chronic malignant and non-malignant pain?
True
Which type of pain (acute, chronic non-malignant, chronic malignant) would you frequently use narcotics to treat?
Chronic malignant pain

Epidural
Which ROA can deliver the greatest potency, but is only used in refractory pain cases?
Intrathecal
True or False - a feeding tube is considered an oral ROA?
True
Clinical presentation of a patient in acute pain would show what signs?
- Increased BP
- Tachycardia
- obvious discomfort
Clinical presentation of a patient in chronic pain would show what signs?
None, no obvious sign of pain
What does the acronym PQRST in pain assessment refer to?
P - Palliation/Provocation - what makes it better or worse?
Q - Quality - how is pain described?
R - Radiates - where is pain and where does it spread?
S - Severity - what is intensity of pain?
T - Temporal - is pain constant or intermittent?
What type of analgesic agents are antidepressants, anticonvulsants, anesthetics, and antispasmodics considered?
Adjuvants
What are Salicylate NSAIDs mostly used to treat? Why is their use limited?
Headaches
Limited use because of GI side effects and bleeding
Which salicylate NSAID is slightly better than the rest because it has no apparent antiplatelet activity (less bleeding than others), although it still has the same GI effects?
Trilisate (choline magnesium trisalicylate)
What positive effect on the patient can NSAIDs have regarding narcotic use?
NSAIDs can decrease the need for narcotics so they’re said to have a narcotic-sparing effect
Name the topical NSAID?
Diclofenac

Ketorolac
Name the (7) NSAID side effects?
- GI toxicity

(NSAID use is limited mostly by 1 & 2)
What is the best option to protect against NSAID GI toxicity?
PPI
If a patient presents with thrombocytopenia, would it be ok for the patient to continue NSAID use?
NO. Thrombocytopenia refers to a decrease in platelets in blood and NSAID already cause reduced platelet activity
True or False - each NSAID has a max dose and ceiling effect?
True
Name the selective COX-2 inhibitor NSAID that causes less GI ulceration, has no antiplatelet activity, has an FDA warning for CV risk, and is used to treat osteoarthritis, RA, and acute pain?
Celecoxib (Celebrex)

True or False - exercise caution with NSAID use in patients that have uncontrolled HT, CHF, and peripheral edema?
True - NSAIDs can cause these conditions
What is the maximum daily dose of APAP?
3g / day
True or False - APAP can mask a fever?
True
Name the DOC for arthritis?
APAP
In what type of patient would you want to exercise caution in with the use of APAP?
patients that drink heavily and/or have liver dysfunction
What (3) opioids (one being off the market already) are bad choices to treat pain?
- Meperidine (Demerol) - neurotoxic metabolite
- Fiorinal/Fioricet - limited use
- Propoxyphene (Darvon/Darvicet)- off market b/c of fatal heart rhythm abnormalities
Name the mixed agonist/antagonist opioid used in women for labor?
Butorphanol (Stadol)
Which schedule III opioid is a partial mu agonist that can be used to treat opioid addiction (in combo with Naloxone) and opiate withdrawal?
Buprenorphine
Which opioid can prolong QTc and is a major CYP3A4 substrate (i.e. its presence would diminish the activity of CYP3A4 to metabolize other drugs)?
Buprenorphine
True or False - Buprenorphine can be used to treat chronic pain in the form of a weekly patch?
True
Name (4) low potency opioid agonists used to treat moderate pain (generic and brand)?
- Codeine (ex. Tylenol #3 w/ codeine)
- Hydrocodone (Vicodin, Norco, Lorcet)
- Tramadol (Ultracet, Ultram)
- Tapentadol (Nucynta)
Which low potency opioid agonist is effective for treatment of neuropathic pain? Is this drug controlled?
Tramadol (Ultracet, Ultram)
No, not controlled
Why is the dosing of hydrocodone limited?
Because it is always combined with a non-narcotic agent (APAP or Ibuprofen) which has a ceiling effect and potential toxicities)
True or False - codeine is inactive?
True - codeine gets metabolized to morphine (active)
Which low potency opioid agonist is schedule II?
Tapentadol (Nucynta)
