Easy Rapid Fire Question # 1 RAPID FIRE QUESTIONSEASY DIFFICULTY • What is the amount of codeine in a Tylenol #4 tablet? – Answer: 60mg – Rationale: Could be easily confused with Tylenol #3, which has 30mg of codeine. 3 6/3/2015 Easy Rapid Fire Question # 2 • What drug is used for opioid reversal? – Answer: Naloxone (Narcan) – Rationale: Naloxone is a μ-opioid receptor competitive antagonist, and its rapid blockade of those receptors often produces rapid onset of withdrawal symptoms. Naloxone also has an antagonist action, though with a lower affinity, at κ- and δ-opioid receptors. Naloxone is a drug used to counter the effects of opiate overdose Easy Rapid Fire Question # 4 • How do NSAIDS inhibit the production of prostaglandins? – Answer: inhibiting COX1 and COX 2 enzymes. – Rationale: Prostaglandins from the COX1 pathway can increase GI blood flow, mucus, bicarbonate production and epithelial growth. NSAIDs inhibiting COX1 enzyme are increasing risk of bleeding by stopping production of these prostaglandins. The COX 2 pathway produces prostaglandins that increase inflammation, and pain. Inhibiting COX 2 decreases pain and inflammation. Risk for GI bleed increases in pts who use NSAIDs, vs those who do not. Easy Rapid Fire Question # 3 • After 2014 prescription combo analgesics will be limited to how many milligrams of acetaminophen per tablet or capsule? – Answer: 325mg – Rationale: The Food and Drug Administration (FDA) is taking steps to reduce the maximum dosage unit strength of acetaminophen in prescription drug products. This change will provide an increased margin of safety to help prevent liver damage due to acetaminophen overdosing, a serious public health problem. Easy Rapid Fire Question # 5 • What compound can be applied topically that is derived from chili peppers? – Answer: Capsaicin cream 4 6/3/2015 Easy Rapid Fire Question # 6 • What is a side effect of opioids that is often confused with an allergic reaction? – Answer: Itching/flushing/sweating/ – Rationale: Codeine causes a histamine release that is a “pseudoallergy” and non immunologic. This can happen with the 1st exposure to the drug, whereas in a true allergy, an initial exposure would have had to happen. Important in choosing pain therapy. Easy Rapid Fire Question # 8 • Which 2 medications are in Vicoprofen®? – Answer: Hydrocodone and Ibuprofen Easy Rapid Fire Question # 7 • What is a non-pharmacologic treatment for back pain that only involves placement of needles? – Answer: Acupuncture. – Rationale: This is a possible treatment option for patients with chronic low back pain. Easy Rapid Fire Question # 9 • When you Increase the dosage of opioids in order to achieve the same analgesic effect is it called tolerance, addiction, or physical dependence? – Answer: Tolerance – Rationale: Tolerance is the process whereby neuroadaptation occurs (through receptor desensitization) resulting in reduced drug effects. Addiction is chronic, neurobiologic disease characterized by behaviors such as: impairment in control over substance use, compulsive substance use, continued substance use despite harm, and substance craving. Physical Dependence is when a patient abruptly stops a medication or is given an antagonist which causes physical withdrawal symptoms. 5 6/3/2015 Easy Rapid Fire Question # 10 • Which medication class is recommended for moderate to severe osteoarthritis pain? Easy Rapid Fire Question # 11 • Name a topical NSAID gel? – Answer: diclofenac gel (Voltaren®) – Answer: NSAIDs – Rationale: American College of Rheumatology recommends NSAIDs for moderate to severe pain but acetaminophen for mild to moderate pain.

Easy Rapid Fire Question # 20 • Name an opioid that is commercially available as a suppository? – Answer: Morphine or Hydromorphone Easy Rapid Fire Question # 19 • Patients will not develop tolerance to which opioid side effect? – Answer: Constipation – Rationale: They will develop tolerance over time to all the other side effects such as nausea, respiratory depression or sedation. Therefore, bowel regimens are important for patients with both acute and chronic opioid exposure Easy Rapid Fire Question # 21 • Oxymorphone is in what schedule of controlled drugs? – Answer: 2 – Rationale: Oxymorphone is a schedule 2 controlled substance meaning there can be no telephone prescriptions and no refills. 8 6/3/2015 Easy Rapid Fire Question # 22 • Which three organ systems are potentially adversely affected by NSAIDs requiring caution with chronic use? – Answer: renal, cardiac, and GI Easy Rapid Fire Question # 24 • True or False. Morphine dosages should be reduced in patients with renal failure. – Answer: True – Rationale: Glucuronide metabolites may accumulate in patients receiving morphine with renal failure, and therefore, dose reduction or use of an alternate agent is recommended. Easy Rapid Fire Question # 23 • Which pain assessment tool is most appropriate to use to assess pain in a 3 year-old child? – Answer: “Faces” scale (Wong-Baker). – Rationale: Generally, this type of scale shows 5 or 6 simple cartoon faces beginning with an emotionally neutral expression on the left, progressing to a very distressed and grimacing face on the right. As with visual analog scales, the child is asked which face best represents how much pain s/he feels. Easy Rapid Fire Question #25 • Which NSAID should be avoided in a patient with a sulfonamide allergy? – Answer: Celecoxib. – Rationale: Celecoxib is a nonarylamine benzenesulfonamide derivative and does not contain a heterocyclic ring attached to the sulfonamide-N1 position, nor does it contain an N4 aromatic amine group. 9 6/3/2015 Easy Rapid Fire Question # 26 Easy Rapid Fire Question # 27 • Meloxicam (Mobic) is available in what two strengths of tablets? • Name the three primary opioid receptors? – Answer: Mu, Kappa, Delta. – Answer: 7.5 mg and 15 mg – Rationale: Meloxicam is available as 7.5 mg and 15 mg tablets, as well as a 7.5mg/5ml suspension. Easy Rapid Fire Question # 28 • Which class of drugs is most effective for the prevention of NSAID-induced gastric ulcers? – Answer: Proton Pump Inhibitors (PPIs). – Rationale: Proton Pump Inhibitors (PPIs) are the preferred agents…however, currently, misoprostol is the only gastroprotective agent proven to decrease risk of clinical GI events (MUCOSA study), but this was at the expense of significant increases in nausea, diarrhea and abdominal pain. Otherwise, misoprostol, double-dose H2 blockers, and PPIs are all associated with significant reductions in risks of endoscopic gastric and duodenal ulcers when added to nonselective NSAIDs relative to nonselective NSAID-use alone in short-term randomized controlled trials (RCTs) Easy Rapid Fire Question # 29 • Which type of pain is commonly described as being burning or electric-like pain? – Answer: Neuropathic pain. – Rationale: Neuropathic pain is defined as pain due to damaged or dysfunctional nerves. It tends to worsen after mechanical stimulation. Nerves can become hyperactive (especially in the case of amputees). 'Pins and needles'; 'cotton-glove feeling'; 'tingling' are all common patient complaints / descriptors. 10 6/3/2015 Easy Rapid Fire Question # 30 • Which opioid analgesic is available in IV, transdermal, and transmucosal preparations? – Answer: Fentanyl.

Easy Rapid Fire Question # 33 • What is the generic name for Kadian®? – Answer: Morphine. – Rationale: Kadian® = morphine sustained release capsules (dosed once daily or divided BID, vs. AVINZA® = morphine extended release capsules, dosed once daily). 11 6/3/2015 Easy Rapid Fire Question # 34 • What is the brand name of the drug used to treat opioid addiction that is available as a sublingual tablet or film? – Answer: Suboxone® or Subutex®. Easy Rapid Fire Question # 36 • Which SNRI has been FDA-approved for the treatment of diabetic neuropathy? – Answer: Duloxetine (Cymbalta®). Easy Rapid Fire Question # 35 • What must be accounted for when switching a patient from one opioid analgesic to another in terms of dosing the new opiod agent? – Answer: Equianalgesic dosing and incomplete crosstolerance (the patient may be more sensitive to the new opioid because of differences in chemical structure and receptor activity). – Rationale: Equianalgesic dosing and incomplete crosstolerance are two of the main considerations when looking to switch a patient between opioid regimens. The patient may be more sensitive to the new opioid because of differences in chemical structure and receptor activity. Easy Rapid Fire Question # 37 • Which anticonvulsant is the drug of choice to treat trigeminal neuralgia? – Answer: Carbamazepine (Tegretol®). – Rationale: Carbamazepine is the first line drug; second line drugs include baclofen, lamotrigine, oxcarbazepine, phenytoin, gabapentin, and sodium valproate. 12 6/3/2015 Easy Rapid Fire Question # 38 • Which opioid analgesic with a long half-life has been associated with Torsades de Pointe? – Answer: Methadone. – Rationale: Methadone may prolong the rate-corrected QT interval (QTc) and result in torsade de pointes. This association recently came into focus when the U.S. Food and Drug Administration (FDA) issued a physician safety alert regarding increasing deaths and cardiac arrhythmias, which was followed by a manufacturer's black box warning. It is recommended to have baseline EKG screening and to recommend routine EKG monitoring (especially if other QTc-prolonging medications are being considered for concomitant therapy).

Medium Rapid Fire Question # 27 • A patient taking methadone and ziprasidone (Geodon) is at an increased risk of what serious side effect? – Answer: QT prolongation or Torsades de Pointes – Rationale: Independently, ziprasidone may prolong the QT interval and methadone has been associated with Torsades de pointes. QT prolongation may lead to torsades de pointes, which is a life threatening arrhythmia. Medium Rapid Fire Question #29 • Identify two risk factors for the development of an NSAIDinduced gastrointestinal bleed? – Answer: Advanced age, high-dose and long-term use, concomitant corticosteroid or anticoagulant use, smoking, alcohol intake. – Rationale: Age, smoking, and alcohol intake all influence the (a) pH of the stomach, and (b) the integrity of the lining of the stomach via inflammation. Additionally, anything that slows the motility and would leave the stomach lining exposed to the NSAID longer would be considered a risk factor for increased ulcer formation. Concomitant use of steroids and/or anticoagulants with NSAIDs nearly doubles the risk of ulcer formation (American College of Gastroenterology) Primarily due to blockade of Cox-1 ▼ mucosal blood flow = ▼ production of mucus and bicarbonate = LESS PROTECTION. 28 6/3/2015 Medium Rapid Fire Question # 30 • Identify two goals of therapy for the management of chronic pain. – Answer: to reduce pain to a level that is acceptable for the patient; -to improve functioning; -to improve quality of life – Rationale: variants of these should be acceptable, but this is the standard IASP and PainEDU.org approach for the initial goals in pain management patients Medium Rapid Fire Question # 32 • Describe how a patient would use a visual analogue pain scale to indicate their level of pain. – Answer: Patients draw a line or dot at a point on a continuous scale from 1 (no pain) to 10 (worst imaginable pain). – Rationale: The visual analogue pain scale is a way to help patients visualize severity of pain.

What is an appropriate dosing regimen for this patient if the doctor plans to prescribe immediaterelease tablets? • A patient has been receiving morphine 10 mg IV every 4 hours. The physician would like to switch the patient to oral morphine. How much oral morphine should this patient receive per dose? – Answer: Oxycodone IR 30 mg po every 4 hours. – Rationale: IR oxycodone would be appropriately prescribed every 3 - 4 hours (can be as often as every 1-2 based on PK). Thus, taking the total daily dose (TDD) of 180 mg and dividing it into 4 hour intervals, 30 mg q4h is appropriate. Staying with the same drug, but a different formulation, does NOT necessitate a % dose reduction because there is no cross-sensitivity to account for. – Answer: Morphine oral:IV ratio is 3:1 so patient should receive morphine 30 mg per dose. – Rationale: Total Daily Dose (TDD) of IV morphine = 60 mg. Using a 3:1 ratio of oral:po morphine, the patient would warrant an oral TDD of morphine of 180mg, or 30 mg po q4h 47 6/3/2015 Hard Rapid Fire Question # 31 • What would be an appropriate regimen of immediate-release morphine for the management of breakthrough pain in a patient who is taking MS Contin® 45 mg po BID? – Answer: Breakthrough pain is calculated as 10 to 15% of the total daily dose. This patient is taking 90 mg per day (10% would be ~9 mg, rounded to 10 mg). Therefore, the patient should receive 10 mg po every 4 hours as needed. – Rationale: Breakthrough doses should ideally utilize an immediate release formulation of the same medication as the scheduled, maintenance dosing. Hard Rapid Fire Question # 33 • Which muscle relaxant can be used to treat intractable hiccups and trigeminal neuralgia? – Answer: Baclofen. – Rationale: The key word here is 'intractable hiccups'. Baclofen is known to be useful for the treatment of this disorder. Hard Rapid Fire Question # 32 • If a patient has an ileostomy, which long acting opioids are the most appropriate? – Answer: Fentanyl patch and Methadone. – Rationale: An ileostomy is a surgical opening constructed by bringing the end or loop of small intestine (the ileum) out onto the surface of the skin. Intestinal waste passes out of the ileostomy and is collected in an external pouching system stuck to the skin. Ileostomies are usually sited above the groin on the right hand side of the abdomen. This would have a significant impact on drug delivery / excretion because of the effect on the GI tract that tends to result in a more rapid transit time. Slow-release medications are NOT a good choice. Transdermal medications are preferred, but a number of publications have pointed to methadone as the oral opioid of choice in these patients for its good absorption profile. Hard Rapid Fire Question # 34 • A patient is admitted to the hospital and is NPO due to a bowel obstruction. The patient usually takes methadone 120mg daily. What is equivalent IV daily dose? – Answer: 60mg, given as 20mg IV q8h – Rationale: The ratio of oral to IV methadone is 2:1.
