Abstract:
Upper airway cough syndrome (UACS), formerly known as postnasal drip syndrome, is one of the most common causes of chronic cough. UACS, asthma, and gastroesophageal reflux make up 90% of the cause of chronic cough. UACS is a clinical diagnosis of exclusion with no diagnostic testing or objective findings. UACS can be present with or without associated rhinitis and chronic rhinosinusitis. Treatment includes dual therapy with H1 receptor antihistamines and decongestants. Diagnosis is confirmed when therapeutic intervention results in symptom resolution.

Upper Respiratory Drugs: Antitussives, Expectorants, and Mucolytics
Antitussives include codeine, dextromethorphan (Robitussin), and benzonatate (Tessalon). Codeine and dextromethorphan exert their effects centrally by suppressing the cough reflex center in the medulla. Benzonatate operates peripherally within the respiratory tract by...
