Ambroxol 15 MG + Guaiphenesin 50 MG + Levocetirizine 2.5 MG + Menthol 1 MGAmerin-CR

How Amerin-CR works

This is a combination, and each component handles a different part of the problem. Levocetirizine and Cetirizine block the H1 histamine receptor. Histamine released from mast cells is what produces the sneezing, itching, watery eyes and runny nose of an allergic reaction, and this newer generation of antihistamine blocks it while barely entering the brain, so the drowsiness of the older agents is largely avoided. Ambroxol thins thick mucus by breaking the bonds that hold it together, so what was sticky and hard to shift becomes loose enough to cough up. Ambroxol also stimulates the surfactant that keeps the smaller airways from collapsing. Guaiphenesin increases the volume of fluid in the airway secretions, which lowers their thickness. Less viscous mucus moves more easily on the cilia lining the airway and needs less effort to clear. Combining them means one preparation covers what would otherwise need two or three.
