Atosyl Syrup contains guaifenesin, an expectorant that loosens phlegm acting by a reflex action, which allows the increase of bronchial secretion, thus, facilitating the expulsion of exudations since it decreases viscosity thereof.

Guaifenesin has been carefully associated with sodium chloride, which acts synergically helping to effectively clear the phlegm and bronchial secretion, making coughing “more productive”.
Atosyl Syrup also contains dextromethorphan hydrobromide, a central action antitussive of great pharmacological activity, which calms coughing fits that rapidly exhaust the patient, irritating the respiratory tract and preventing drowsiness.

It is indicated in cases of spasmodic and reflex cough caused by colds or respiratory tract infections: laryngitis, trachea bronchitis, pneumonias, nervous cough, and smokers’ cough.
