Ascoril LS Junior Expectorant is used to provide relief from cough associated with bronchitis, bronchial asthma, chronic obstructive pulmonary disease (COPD), emphysema (damage of air sacs in the lungs) and other bronchopulmonary disorders where bronchospasm, mucous plugging and problems of expectoration co-exist. Coughing (dry or productive) is the body's way of clearing irritants (like allergens, mucus or smoke) from airways and preventing infection.
