Viscotin 600 mg Effervescent Tablet contains Acetylcysteine, a mucolytic agent that reduces the viscosity of mucus by breaking disulfide bonds in mucoproteins. This action facilitates the clearance of mucus from the respiratory tract, aiding in conditions characterized by thick and viscous secretions. Additionally, Acetylcysteine exhibits antioxidant properties by replenishing intracellular glutathione levels, thereby protecting lung tissue from oxidative damage.
