Montelor 5mg/10mg Tablet is a fixed-dose combination product containing desloratadine 5mg and montelukast 10mg. This once-daily tablet is indicated for the treatment of seasonal allergic rhinitis and perennial allergic rhinitis in adults and children aged 6 months and above. Montelukast, a leukotriene receptor antagonist, inhibits the cysteinyl leukotriene-mediated allergic response, while desloratadine, a non-sedating antihistamine, effectively blocks histamine-induced responses. The combination of these two agents provides a comprehensive approach to managing allergic rhinitis symptoms, including nasal congestion, rhinorrhea, sneezing, and itchy, watery eyes. Montelor 5mg/10mg Tablet also helps to alleviate pruritus, nasal discharge, and postnasal drip. The tablet is taken orally, once daily, with or without food, and is suitable for patients who have not responded to, or are intolerant to, other therapies. It is essential to follow the recommended dose and administration schedule to ensure optimal efficacy and minimize the risk of adverse events.
