Cough is a reflex action that clears your airway of irritants and mucus. A nonproductive cough, also known as a dry cough, doesn’t produce phlegm or mucus. Many things — from allergies to acid reflux — can cause a dry cough. In some cases, there’s no obvious cause. Common causes are listed below-



Asthma is a condition in which your airways swell and become narrowed. Asthma-related coughs can be both productive and nonproductive, but they’re frequently nonproductive. Coughing is a common symptom of asthma, but it’s usually not the most prominent one. However, there’s a type of asthma called cough variant asthma (CVA) that includes a chronic dry cough as its main symptom.


Gastroesophageal reflux disease

Gastroesophageal reflux disease (GERD) is a type of chronic acid reflux. It happens when stomach acid regularly flows back up into your esophagus, which connects your mouth to your stomach. Stomach acid can irritate your esophagus and trigger your cough reflex.

Mechanism of Action

Dextromethorphan, a centrally-acting antitussive agent, depresses the medullary cough centre through sigma receptor stimulation, resulting to decreased sensitivity of cough receptors and interruption of cough impulse transmission. Bromhexine is used in a condition where there is a lot of thick phlegm in the airways. As a mucolytic, it helps to relieve productive cough by thinning the phlegm in the airways and facilitating the removal of the mucus.
