The Levozet M Tablet contains two active ingredients:
Levocetirizine (5 mg): This component is a potent H1 histamine receptor antagonist. It works by blocking the action of histamine at H1 receptors in your body. Histamine is a substance that your body produces during an allergic reaction, leading to effects like blood vessel dilation (widening), increased vascular permeability (leakiness), and stimulation of smooth muscles in various organs. By blocking these effects, Levocetirizine helps reduce symptoms such as sneezing, itching, runny nose, and watery eyes.
Montelukast (10 mg): Montelukast acts as a leukotriene receptor antagonist. Leukotrienes are chemicals your body releases when you breathe in an allergen (something you're allergic to). They cause inflammation and mucus secretion in your airways, leading to symptoms of allergic rhinitis. Montelukast works by blocking the action of leukotrienes, thereby reducing these allergic reactions.
