Koflet is beneficial in both productive and dry cough. The mucolytic and expectorant properties reduce the viscosity of bronchial secretions and facilitate expectoration. Kofletâs peripheral antitussive (cough suppressant) action reduces bronchial mucosal irritation and related bronchospasms. In addition, the anti-allergic, antimicrobial and immune-modifying properties provide relief from cough. The demulcent action of Koflet syrup soothes respiratory passages.
