For adult patients, CHRONIC COUGH is a cough that persists for >8 weeks.3
Cough as a medical problem can be evaluated by its duration, characteristics, severity, etiology, pathophysiology, or treatment response.4
Chronic cough is often associated with an underlying condition, such as asthma, GERD, UACS (postnasal drip), and NAEB.3,5
GERD, gastroesophageal reflux disease; UACS, upper airway cough syndrome; NAEB, nonasthmatic eosinophilic bronchitis.
In some patients with chronic cough, treatment of an underlying condition does not resolve the cough, or an underlying condition cannot be identified.6
Refractory chronic cough (RCC) is a chronic cough that persists despite appropriate treatment for an underlying condition(s).6
Unexplained chronic cough (UCC) is a chronic cough with no underlying etiology identified, despite a thorough diagnostic workup.6
Cough hypersensitivity is a common characteristic in patients with chronic cough.5,7
