    Study Notes

    • Antihistamines work by blocking histamine at H1 receptors to prevent its action, used for hypersensitivity reactions, seasonal allergies, nausea, vomiting, and motion sickness.
    • First-generation antihistamines include diphenhydramine, hydroxyzine, and promethazine, while second-generation ones include cetirizine, loratadine, fexofenadine, and desloratadine.
    • Side effects of antihistamines may include drying effect, drowsiness, hypotension, gastrointestinal irritation, photosensitivity reactions, and paradoxical excitement.
    • Nursing implications for antihistamines involve taking with food (except loratadine), avoiding fruit juice with fexofenadine, administering parenterally in a deep IM injection, and monitoring drowsiness levels.
    • Nasal decongestants are used to drain sinus cavities, with corticosteroids decreasing mucous formation and sympathomimetics constricting blood vessels in the nose.
    • Side effects of nasal decongestants can be systemic (CNS and cardiac stimulation) and local (rebound congestion), requiring assessment of nasal mucosa and monitoring blood pressure and heart rate.
    • Antitussives can be central acting (suppressing cough reflex center) or peripheral acting (acting directly on cough receptors), with examples like codeine, hydrocodone, dextromethorphan, and benzonatate.
    • Nursing implications for antitussives involve avoiding in conditions like COPD and asthma, ensuring benzonatate capsules are swallowed whole, and informing the physician if cough persists beyond 5-7 days.
