[Chronic cough].
Cough becomes chronic after three weeks of evolution. Chronic cough is due to four syndromes in 90% of cases: postnasal drip syndrome, asthma, gastroesophageal reflux and chronic bronchitis. Each syndrome needs a specific therapeutic approach. Antitussive drugs like dextromethorphan are prescribed in cases of complicated cough. Cough secondary to angiotensin converting enzyme inhibitors must not be neglected. In case of failure of initial check up or lack of response to specific therapy, a more thorough examination must be conducted in a specialized centre.
