Dear Dr. {{ $doctorName }},

Subject: Participation in survey “Understanding the epidemiology and management of cough in clinical practice”

Cough is one of the most common symptoms for which outpatient care is asked, accounting for up to 40% of the practice activity. Coughing is an important defensive reflex that enhances clearance of secretions and particulates from the airways and protects from aspiration (breathing foreign objects into your airways) of foreign materials occurring as a consequence of aspiration or inhalation of particulate matter, pathogens, accumulated secretions, postnasal drip, inflammation, and mediators associated with inflammation. Under normal conditions cough serves an important protective role in the airways and lungs, but in some conditions it may become excessive and nonproductive, and is troublesome and potentially harmful to the airway mucosa.

This cross-sectional survey is designed to understand the epidemiology, etiology and cough medication usage pattern & management of persistent cough during day to day practice in India.

If you agree to participate, you will be required to respond to questions of the enclosed questionnaire. We trust you and we are partners in promoting safe and effective drug therapy.
