Costus NP Junior Suspension is a pediatric antitussive and mucolytic oral suspension used for the symptomatic relief of cough associated with respiratory tract infections. It helps in reducing cough frequency, loosening mucus, and improving airway clearance in children.

This formulation contains a combination of Noscapine, Ammonium Chloride, and Sodium Citrate, which work together to suppress dry cough, liquefy bronchial secretions, and make mucus easier to expel from the respiratory tract.

Noscapine acts as a cough suppressant by acting on the cough center in the brain, while Ammonium Chloride and Sodium Citrate help in thinning and loosening mucus, providing smoother breathing and relief from chest congestion.

Costus NP Junior Suspension is generally recommended for pediatric use under medical supervision for cough associated with cold, bronchitis, and other respiratory tract conditions.
