Mechanism of action

Staloral is a sublingual immunotherapy (SLIT) tablet containing standardized grass pollen allergen extract. It works by gradually exposing the immune system to increasing doses of the allergen, promoting immune tolerance through induction of regulatory T cells and shift toward Th1/Treg responses. This reduces allergic symptoms and the need for symptomatic medications in patients with grass pollen-induced allergic rhinitis and asthma.
