Fexofenadine & Montelukast Sodium Tablets

Montelukast is an anti-leukotriene drug. It operates by inhibiting the function of leukotriene, a chemical messenger. This relieves symptoms by reducing inflammation (swelling) in the airways and nose. Fexofenadine is an antiallergic that works by blocking the action of histamine, a chemical messenger that causes runny noses, watery eyes, and sneezing.
