Antitussive Therapy
When cough performs no useful function and it is an annoyance or its complications represent a real or potential hazard, antitussive therapy is indicated. Antitussive therapy can be categorized as definitive or nonspecific. It is definitive when it eliminates cough. Definitive therapy is directed in a specific way at either the etiology (eg, killing the tubercle bacillus in tuberculosis; smoking cessation in chronic bronchitis) or the presumed operant pathophysiologic mechanism responsible for cough (eg, eliminating the postnasal discharge in allergic rhinitis and chronic sinusitis).
Nonspecific therapy is directed at the symptom, rather than the underlying etiology or mechanism; consequently, its aim is to control, rather than to eliminate cough. It is indicated when definitive therapy cannot be given either because the cause of the cough is unknown or because definitive therapy has not had a chance to work or will not work (eg, cancer metastatic to lung).
