mometasone furoate + levocetirizine + oxymetazoline

This is a fixed-dose combination drug containing three active ingredients: - **Mometasone furoate** is a synthetic corticosteroid with potent anti-inflammatory activity, primarily used to treat allergic rhinitis and nasal polyps by reducing inflammation in the nasal passages. - **Levocetirizine** is a third-generation non-sedating antihistamine that acts as an antagonist at the histamine H1 receptor, providing relief from allergy symptoms such as sneezing, itching, and rhinorrhea. - **Oxymetazoline** is an imidazoline derivative and direct-acting sympathomimetic agent that acts as an agonist at alpha-1A adrenergic receptors (and to some extent alpha-2B), causing vasoconstriction of nasal blood vessels and rapid relief of nasal congestion. The combination targets multiple mechanisms involved in allergic rhinitis and related conditions—reducing inflammation (mometasone), blocking histamine-mediated symptoms (levocetirizine), and relieving congestion through vasoconstriction (oxymetazoline). Clinical studies on similar combinations have shown improved symptom control for allergic rhinitis compared to monotherapy[1][2][9].
