Medication And Non-Drug Therapy Selection - NAPLEX

1. What medication class must be avoided in pregnancy due to fetotoxicity (renal failure, oligohydramnios)?

   ACE inhibitors and ARBs. These inhibit the renin-angiotensin system, causing fetal renal damage, oligohydramnios, and other teratogenic effects during pregnancy.

2. What is the first-line regimen for Helicobacter pylori when local clarithromycin resistance is high or unknown?

   Bismuth quadruple therapy. This regimen uses bismuth and multiple antibiotics to eradicate H. pylori despite potential clarithromycin resistance.

3. Which urate-lowering therapy is first-line for chronic gout prevention?

   Allopurinol. As a xanthine oxidase inhibitor, it reduces uric acid production to maintain low serum urate levels and prevent gout flares.

4. Which medication is first-line for smoking cessation when no contraindications exist?

   Varenicline. As a partial nicotinic agonist, it reduces cravings and withdrawal while blocking nicotine's rewarding effects.

5. What is the preferred initial inhaler regimen for COPD with persistent symptoms and low exacerbation risk?

   Long-acting bronchodilator (LAMA or LABA). GOLD guidelines recommend long-acting bronchodilators for symptom relief in low-risk COPD patients without frequent exacerbations.

6. Which antidepressant class is generally first-line for major depressive disorder?

   SSRI (or SNRI as an alternative first-line option). SSRIs enhance serotonin neurotransmission with a favorable efficacy and tolerability profile for depression treatment.

7. Which anticoagulant is preferred for stroke prevention in nonvalvular atrial fibrillation in most patients?

   DOAC (apixaban, rivaroxaban, dabigatran, or edoxaban). DOACs provide effective stroke prevention with lower intracranial bleeding risk and no routine monitoring compared to warfarin.

8. Which medication is first-line for acute mania in bipolar I disorder requiring pharmacotherapy?

   Lithium, valproate, or an atypical antipsychotic. These mood stabilizers or antipsychotics rapidly control manic symptoms by modulating neurotransmitters and neuronal excitability.

9. Which first-line medication class is preferred for uncomplicated primary hypertension in most adults?

   Thiazide diuretic, ACE inhibitor, ARB, or dihydropyridine CCB. These classes are recommended by ACC/AHA guidelines as initial therapy due to proven efficacy in reducing cardiovascular events in uncomplicated hypertension.

10. Which non-drug therapy is first-line for insomnia before initiating hypnotics?

    Cognitive behavioral therapy for insomnia (CBT-I). CBT-I modifies maladaptive sleep behaviors and cognitions for sustained insomnia improvement without medication dependence.

11. Which controller therapy is first-line for persistent asthma across age groups?

    Inhaled corticosteroid (ICS). GINA guidelines endorse ICS as they target airway inflammation, the key pathophysiology in persistent asthma.

12. Which glucose-lowering drug class is preferred for type 2 diabetes with HFrEF or CKD progression benefit?

    SGLT2 inhibitor (if eGFR allows). SGLT2 inhibitors reduce heart failure hospitalizations and slow CKD progression via hemodynamic and anti-inflammatory effects.

13. What is the first-line nonpharmacologic therapy for mild to moderate osteoarthritis of knee or hip?

    Exercise, weight loss if overweight, and physical therapy. ACR guidelines prioritize these to strengthen muscles, reduce joint load, and improve function without pharmacologic side effects.

14. Which medication is first-line for neuropathic pain due to diabetic peripheral neuropathy?

    Duloxetine, pregabalin, gabapentin, or a TCA. These modulate central pain pathways, providing relief from neuropathic symptoms in diabetic neuropathy per guidelines.

15. Which medication is first-line for GERD requiring long-term symptom control and healing of erosive esophagitis?

    Proton pump inhibitor (PPI). PPIs inhibit the proton pump to suppress acid secretion, promoting esophageal healing and symptom relief in GERD.

16. Which medication is first-line for acute gout flare in a patient without major contraindications?

    NSAID, colchicine, or systemic corticosteroid. These agents rapidly reduce inflammation and pain from monosodium urate crystal deposition in acute gout.

17. What is the first-line pharmacotherapy for type 2 diabetes without contraindications?

    Metformin. ADA guidelines recommend it for improving insulin sensitivity and reducing hepatic glucose output with minimal hypoglycemia risk.

18. What is the preferred first-line antibiotic for uncomplicated cystitis in a nonpregnant adult woman?

    Nitrofurantoin, TMP-SMX, or fosfomycin. IDSA guidelines favor these for their efficacy against E. coli and low resistance in uncomplicated urinary tract infections.

19. Which beta-blocker has the strongest evidence for mortality benefit in HFrEF?

    Carvedilol, metoprolol succinate, or bisoprolol. These beta-blockers have demonstrated mortality reduction in large clinical trials for heart failure with reduced ejection fraction.

20. Which anticoagulant is preferred for atrial fibrillation with a mechanical heart valve?

    Warfarin. Warfarin is required for its adjustable anticoagulation in patients with mechanical valves to prevent thromboembolic complications.

21. Which medication is first-line for acute anaphylaxis, and what is the route?

    Epinephrine intramuscularly. IM epinephrine rapidly activates alpha and beta receptors to reverse hypotension, bronchospasm, and angioedema in anaphylaxis.

22. Which glucose-lowering drug class is preferred for type 2 diabetes with ASCVD benefit?

    GLP-1 receptor agonist or SGLT2 inhibitor with ASCVD benefit. These classes have evidence from CVOTs showing reduction in major adverse cardiovascular events in diabetic patients with ASCVD.

23. Which antibiotic is preferred for acute uncomplicated pyelonephritis requiring oral outpatient therapy?

    Fluoroquinolone (if local susceptibility is adequate). Fluoroquinolones provide broad gram-negative coverage and high renal concentrations for outpatient pyelonephritis treatment.

24. What is the first-line medication class for secondary prevention after ischemic stroke or TIA (non-cardioembolic)?

    Antiplatelet therapy (aspirin or clopidogrel). Antiplatelets inhibit platelet aggregation to prevent recurrent atherothrombotic events post-stroke or TIA.

25. Which medication is preferred for chronic hepatitis B in a patient at risk for renal or bone toxicity?

    Tenofovir alafenamide (TAF) or entecavir. These nucleoside analogs inhibit HBV replication with lower risks of renal impairment or bone density loss compared to alternatives.
