Salbutamol is a direct-acting sympathomimetic with adrenergic activity and selective action on 2 receptors, producing bronchodilating effects. Guaiphenesin increases the volume and reducing the viscosity of secretions in the trachea and bronchi. Bromhexine disrupts the structure of acid mucopolysaccharide fibres in mucoid sputum and produces less viscous mucus, which is easier to expectorate. Menthol is a powerful demulcent. Diphenhydramine blocks the effects of the naturally occurring chemical histamine in the body and thus reduces mucosal irritation & mucus secretion. Ammonium Chloride and Sodium Citrate are saline expectorants & their expectorant action is caused by irritation of the bronchial mucosa. Menthol is a powerful demulcent. Glycirrhiza glabra is an effective expectorant. Terminalia belerica has a powerful action in acute/ chronic cough, bronchitis, sore throat and common cold. Zingiber officinale is very useful in controlling and curing chronic and repetitive cough / cold bouts. Curcuma longa is a very strong immunomodulator, antiallergic and anti-inflammatory agent. It also acts as a mucolytic and helps to remove excess cough. Menthol is a powerful, expectorant and demulcent.
