Mechanism of action

Ciclesonide works by binding to glucocorticoid receptors in the lungs, suppressing inflammatory cytokine production and reducing airway edema and mucus secretion. Levocetirizine competitively blocks H1 histamine receptors on mast cells and other immune cells, preventing histamine-induced allergic symptoms such as itching, sneezing, and rhinitis. Together, they provide dual anti-inflammatory and antihistamine effects for allergic airway disease.
