Mechanism of action

By sequestering free IgE, Xolair reduces the allergic cascade activation that would normally occur when allergens cross-link IgE-receptor complexes on mast cells and basophils. This prevents the release of inflammatory mediators (histamine, tryptase, leukotrienes) that drive allergic symptoms. The reduction in IgE-mediated signaling is particularly effective in IgE-driven allergic and asthmatic conditions.
