loratadine + budesonide + emedastine difumarate

This is a combination drug consisting of loratadine, budesonide, and emedastine difumarate. Loratadine is a second-generation antihistamine that acts as an inverse agonist at the histamine H1 receptor, reducing symptoms of allergic rhinitis and urticaria by blocking the action of histamine released during allergic reactions[2][5][10]. Budesonide is a synthetic glucocorticoid corticosteroid with potent anti-inflammatory properties; it reduces inflammation in the airways and nasal passages by inhibiting multiple inflammatory cytokines and mediators[1][4]. Emedastine difumarate is a selective H1-receptor antagonist used primarily as an ophthalmic solution for allergic conjunctivitis but also relieves symptoms associated with allergic rhinitis when used topically or in combination regimens[8][9]. The combination targets multiple pathways involved in allergy—histamine-mediated symptoms (via two different antihistamines) and local inflammation (via corticosteroid)—and may provide enhanced symptom control for conditions such as allergic rhinitis.
