Gastroesophageal reflux disease (GERD), asthma syndromes, smoker's cough, nonasthmatic eosinophilic bronchitis, and upper airway cough syndrome (UACS) associated with postnasal drip (rhinitis or rhinosinusitis) are the most common conditions associated with chronic cough in adults who are nonsmokers and are not receiving therapy with angiotensin converting enzyme (ACE) inhibitor [6, 8–10]. Here, ACE is linked to rhinitis.
