Alkof Plus Cough Syrup 100 ml belongs to the 'expectorant' class of respiratory medications, which are primarily used to treat cough. It aids in the dissolution of hard phlegm (sputum/cough), which makes breathing difficult in respiratory problems such as allergies, sinusitis, common cold, bronchitis, flu, and so on. Coughing (whether dry or productive) is the body's way of clearing irritants from the airways and preventing infection.Disclaimer:For More Information Contact Your Physician
