How Methonac Tablet Works

Methonac Tablet works directly on the structure of the mucus in your respiratory tract. Thick mucus contains chemical bonds (called disulfide bonds) that hold it together, making it sticky and difficult to clear. The active ingredient in Methonac Tablet contains a free sulfhydryl (thiol) group that helps break apart the disulfide bonds holding thick mucus together. This reduces the mucus's thickness and stickiness, making it easier to cough up and clear from your airways. Once the mucus becomes thinner and more fluid, the natural sweeping motion of your airways (cilia) and your cough reflex help remove it more effectively.
