Changes in terminology and management of over-the-counter cough therapy - Time for a fresh perspective?

Coughing is one of the most common symptoms for which patients consult their healthcare practitioners. Their coughing may be caused by various factors such as respiratory tract infections, asthma, inhaled irritants, postnasal drip syndrome and gastro-oesophageal reflux disease (GORD). Terminology that includes 'wet' and 'dry' has become outdated and should be revisited. An understanding of the pathophysiology of coughs and how they manifest themselves enables the health professional to provide the necessary therapy.
