RONDEC C SYRUP L 120ML

Dextromethorphan suppresses a cough by depressing the cough center in the medulla oblongata or the cough receptors in the throat, trachea, or lungs. Carbinoxamine competes with free histamine for binding at HA-receptor sites. This antagonizes the effects of histamine on HA-receptors, leading to a reduction of the negative symptoms brought on by histamine HA-receptor binding.Pseudoephedrine is used to relieve nasal congestion caused by colds, allergies, and hay fever. Guaifenesin loosens and thins phlegm and bronchial secretions to ease expectoration
