    Initiating COPD Medication Therapy Using GOLD Guidelines

    • GOLD Group A: Short-acting bronchodilator (SABA or SAMA) as needed.
    • GOLD Group B: Long-acting bronchodilator (LABA or LAMA).
    • GOLD Group E: Combination of LAMA or LABA, or dual LAMA/LABA, depending on severity.

    Goals of COPD Therapy

    • Relieve symptoms.
    • Improve exercise tolerance.
    • Reduce frequency and severity of exacerbations,
    • Decrease mortality.

    Management of Acute COPD Exacerbation

    • Outpatient: SABA (e.g., albuterol) with or without a SAMA (e.g., ipratropium), and possibly a short course of oral corticosteroids (e.g., prednisone 40 mg for five days).
    • Inpatient: Supplemental oxygen to maintain saturation >90%, nebulized SABA/SAMA, systemic corticosteroids, and, if indicated, antibiotics for increased sputum purulence or dyspnea.

    Proper Inhaler Technique

    • Metered Dose Inhaler (MDI): Shake, exhale, press, and inhale slowly over 3-5 seconds, hold breath for 10 seconds.
    • Dry Powder Inhaler (DPI): Load dose, exhale away from the inhaler, inhale quickly and deeply for 1-2 seconds, no shaking required.
    • Respimat/Soft Mist Inhaler: Twist base, open cap, press to release mist while inhaling slowly.
    • Nebulizer: Primarily for patients unable to use MDIs during exacerbations.

    Symptoms of Nicotine Withdrawal

    • Craving, nervousness, restlessness, irritability, mood swings, anxiety, sleep disturbances, increased appetite.

    Prescribing Smoking Cessation Therapy

    • Nicotine Replacement Therapy (NRT) (patch, gum, lozenge), Varenicline (Chantix), and Bupropion (Zyban).
    • Therapy selection may depend on patient preference, previous attempts, and comorbidities.

    Follow-Up After Smoking Cessation Prescription

    • Monitor for withdrawal symptoms.
    • Evaluate adverse effects of cessation medications.
    • Reinforce cessation strategies.
    • Provide support through behavioral counseling or referrals to support services.
    • Adjust therapy as needed based on patient response and challenges.
