Febrikast BT 20mg/10mg Tablet is a combination medication containing Bilastine 20mg and Montelukast 10mg, designed to provide effective relief from allergic conditions. Bilastine is a second-generation antihistamine that works by selectively blocking peripheral H1 histamine receptors, thereby reducing symptoms such as sneezing, runny nose, itching, and watery eyes commonly associated with allergic rhinitis and urticaria. Montelukast, on the other hand, is a leukotriene receptor antagonist that helps prevent inflammation and bronchoconstriction by inhibiting the action of leukotrienes, which are substances involved in allergic and asthmatic responses. The synergistic effect of these two active ingredients makes Febrikast BT particularly useful in managing symptoms of seasonal allergic rhinitis, perennial allergic rhinitis, and asthma-related allergic reactions. This combination not only alleviates nasal and ocular allergy symptoms but also helps improve respiratory function by reducing airway inflammation and bronchospasm. Febrikast BT is generally well-tolerated, with a low incidence of side effects, making it suitable for adults and adolescents. It should be taken as prescribed by a healthcare professional, and patients are advised to inform their doctor about any other medications or existing health conditions before starting therapy.
