Pharm Exam 2 Review Guide (40-50 Questions) 1. For your monoclonal antibodies I want you to identify their mechanism of action and their shared adverse effects. Biologics (Monoclonal Antibodies Drugs Notes Adverse Effects Omalizumab (Xolair) MOA: Recombinant anti-IgE antibody → decreased inflammatory mediator release BLACK BOX WARNING → Anaphylaxis (rare) - Inhibits the binding of IgE on the surface of mast cells ↳Has occurred up to 12 months post 1st dose G omalizumab IgE mart - Moderate or severe allergic asthma not controlled with ICS - Dosing based on weight and IgE levels - Injection site reactions: including flu-like symptoms (e.g., myalgias) & pain at site of injection cellv - Increased risk of infections (fungal & helminth) F Dupilumab (Dupixent) MOA: Interleukin-4 antagonist → decreased inflammatory mediator release - Anaphylaxis (does not have a Black Box warning) E 11-4 antagonist - Moderate or severe allergic asthma not controlled with maintenance therapy - Injections site reactions: including flu-like symptoms and injection site pain - Increased risk of infections (herpes & helminths) Benralizumab (Fasenra) - MOA: Recombinant Interleukin-5 Antagonists - Anaphylaxis Mepolizumab (Nucala) Reslizumab (Cinqair) Isagonist - Severe asthma with eosinophilic phenotype - Injection site reactions - Increased risk of infections ROV Palivizumab (Vynagiu) MOA-antibody against epitope in A antigen rite on Fourface protein of extensive , high-risk infant 2. If I have any slides that are like hey we're studying this condition but there are drugs that make this condition worse you should be familiar with those slides. Asthma Cannot use monotherapy LABA → increased risk of death COPD Cannot use monotherapy ICS → increased risk of PNA 3. So what can exacerbate asthma? Does anybody want to throw anything out? What kind of drugs can exacerbate asthma? Aspirin can, propranolol, estrogen has some concerns and I do believe that slide was completely yellow. So although I tell you guys not to memorize a lot of stuff. I think that one's important. Go ahead and memorize that one. Drugs & Asthma - Estrogen replacement therapy during menopause may exacerbate asthma → Outcome absent when estrogen is given in combination with progesterone (mechanism not understood; estrogen decreases may exacerbate asthma during PMS) - Aspirin → Cyclooxygenase-1 (COX-1) inhibition → Inhaled corticosteroids (ICSs) are the primary preventative treatment - Nonselective 𝛃-blocking agents (e.g., propranolol) → These drugs do not precipitate bronchospasm but prevent its reversal 4. I'll give you an acute asthma exacerbation patient. I'll give you the age, I'll give you the weight, I'll tell you the weight dose to prescribe. I'll tell you how to round on it and you tell me what to give. How many milligrams of the steroid to give. 5. On Wednesday we'll look at the different steps one through step five. Identify which medications are on each step and for which patient population they get used. Determine step by using GINA Guidelines screening recommendations - Preferred vs alternative.

You'll want to be able to step people up and step people down and to some degree, you'll want to be able to say which category they would be in whether it's intermittent or persistent and then if it's persistent is it mild, moderate, or severe. I'm not crazy about making you guys memorize all that stuff. So I'm still thinking about the best way to present it. If classified as intermittent, the patient will be put into Step 1 treatment. In the case of persistent symptoms/exacerbations, they will be put on step 2-5 depending on severity (mild, moderate or severe). In order to determine step placement, you consider frequency of SABA use, nighttime awakenings, FEV1, FEV1/FVC, and frequency of exacerbations. Using GINA Guidelines screening recommendations, you determine which of the factors is most abnormal (which of the factors is the worst one) and utilize that factor to determine step. GINA Guidelines Screening Recommendations Intermittent (Step 1) Persistent - Mild (Step 2) Persistent - Moderate (Step 3) Persistent - Severe (Steps 4 & 5) Symptoms/SABA (reliever) use ≤ 2 days a week > 2 days a week Daily Throughout the day (multiple times) Nighttime awakenings ≤ 2/month 3-4/month >1/week Nightly (0-4 years old) (0/month) (1-2/month) (3-4/month) (>1/week) FEV1 >80% 60-80% 1 day) 7. There are so many different drugs for asthma and COPD. We're only going to talk about a few and their specific devices and how you should counsel a patient on those. For example, we’ve talked about the MDI albuterol inhalers. What's priming? How often are they cleaned? How long do I wait in between inhalations? Devices MDI albuterol inhalers - Priming: Before first use (or if it’s been more than 7 days since the last use), point the inhaler at the ground and do two puffs to “prime” it - Cleaning: Use warm water to clean only the plastic part of the MDI holder VABA - Wait 15-30 seconds between puffs with a beta2-agonist inhaler Nebulizers - Children < 6 y/o require the use of a face mask as opposed to a mouthpiece for delivery of aerosolized medication Spiriva Respimat & Combivent - Daily use → TOP (turn, open, press) - Multiple dates on the inhaler - 1st date: label from pharmacy “expires in 1 year” LAMA - 2nd date: date on manufacturers box - 3rd date: one that the patient writes on the inhaler Spiriva Handihaler Once-daily dosing in 4 simple steps: 1. Open the handihaler device. Separate only one of the blisters from the blister card, then open the blister. If you accidentally open another blister, the capsule in that blister should not be used. 2. Insert the SPIRIVA capsule and close the mouthpiece firmly against the gray base until you hear a click. LAMA 3. Press the green piercing button once until it is flat against the base, then release. 4. Breathe out completely in one breath and then, with the HANDIHALER in your mouth, breathe in deeply until your lungs are full. You should hear or feel the SPIRIVA capsule vibrate (rattle). Advair Diskus - Breathe all the way out - Breathe in the medicine quickly and deeply through the DISKUS 1TV - 1ABA - Remove the DISKUS from your mouth and hold your breath for 10 seconds - RINSE YOUR MOUTH OUT AFTERWARDS (((v) Trelegy - Steps for use: 1. Open the cover of the inhaler. 2. Breathe out. 3. Inhaler your medicine. Don’t block the vent with your fingers. Remove the inhaler from your mouth and hold your breath for 3 to 4 seconds ICS/LABA/LAMA 4. Breathe out slowly and gently. 5. Close the inhaler. 6. RINSE YOUR MOUTH. 8. Tell me everything about Montelukast. Leukotriene Modifiers MOA: Reduction of production or action of leukotrienes in inflammation and allergy; reduces airway edema and smooth muscle contraction Side Effects: - Headache - GI upset - Psychiatric effects (rare) INCREDIBLY RARE: idiosyncratic syndrome similar to Churg-Strauss syndrome, with marked circulating eosinophilia, HF, and associated eosinophilic vasculitis, has been reported in a small number of patients Drugs Notes Side Effects / Warnings Montelukast (Singulair) - Leukotriene receptor antagonist (LTRA) - Approved for exercise-induced bronchospasm asthma (EIB asthma) 9. Here's another question where you have to stratify the patient's severity, determine what step to be in, and whether to step up or step down. 10. What are the differences in treatment options available for somebody with acute asthma exacerbation and think about it as mild & moderate versus severe. What objective data would tell you is severe? What drugs can you use if it's severe? Is there any difference between IV versus oral corticosteroids? Determining Course of Care - We will use the objective measures for mild, moderate and severe in this algorithm to determine the course of care for our exams. - Important measures for determine mild/moderate versus severe: methylpredivolone hydrocortisone + dexamethrone V Po in = - Mild or moderate , , → Respiration rate increased → Pulse rate 100-120 bpm PREDNIONE S → O2 saturation (on air) 90-95% → PEF >50% predicted or best NEVERE ACUTE EXACERBATION - Severe RR > 30/ min children 12 mg/kg/day 3-Sdayr max → Respiratory rate >30/minute > - HR) 120 Dpm PEF 50 % best adults 40-60 mg/day → Pulse rate > 120 bpm S-7 dayrdaya → O2 saturation (on air) < 90% O2 rat 65 y0 IMPLE azithromycin 500 Quay I - Azithromycin 500 mg PO once daily (PAE; 5 days of therapy acceptable) COPD - Augmentin 875 mg BID - Doxycycline 100 mg BID Aug.

If I ask for prednisone, or if I ask for like a steroid question, I'll give you the equivalence. So you just got to be able to do the math.

Azithromycin is weird because it's an antibiotic that can be used long-term in COPD. Tell me about that. That's kind of unique, right? Because normally when I think of azithromycin, I'm thinking z-pack, infection, 500 milligrams on day 1, 250 milligrams thereafter. It's got a post-antibiotic effect, so I only need to use it for five days and serum concentrations will persist. There's some unique stuff about azithromycin and COPD. Tell me about it. Macrolides for COPD Drugs Notes Adverse Effects / Warnings Azithromycin - Lower rate of exacerbations and improved quality-of-life scores - No benefit if still smoking - avoid combination - Dosing 250 mg Qday or 250 mg three times weekly; reassess after 12 months 250mg Qday OR 3x/wk - Increased risk of hearing loss for COPD cohort Adverse effects and drug interactions → QT prolongation: - Amiodarone (very serious) - Given the risk of adverse effects with ICS, clinicians may consider by-passing triple inhalation therapy (LAMA/LABA/ICS) for those patients with persistent - Flecainide (all antiarrhythmics) exacerbations and lower blood eosinophil count ( - ↓ replication) Indication Treatment Prophylaxis - 75 mg once - daily x 5 day - Weight based dose for pediatrics BID - 75 mg once daily x 10 days - Weight based dose for pediatrics Ye down - CrCl 30-60 mL/min → 30 mg BID x 5 days - CrCl 30-60 mL/min → 30 mg once daily x 10 days =mL/min → 30 mg once daily x 5 days - CrCl 10-30 - 12 interval - CrCl 10-30 mL/min → 30 mg every other day (QOD) x 10 days 30.

For the upper respiratory infections, I focused a lot on when do you substitute drugs for allergies? If somebody has a penicillin allergy and it's a type 2, such as like a dermatological reaction, you should feel fine writing a cephalosporin. There's only a 10% chance that it could cause an issue. If it’s a type 1, you might need to think about something else even if it's normally avoided. Like there can be instances where you use fluoroquinolones in pediatrics for a type 1 penicillin allergy. DNA gyrave Chisynthesis) He kind of answered his question. 32. There's another pneumonia question. I don't do anything tricky on any of these doses. Every dose I list is a real dose.
