DRUG INFO
Omalizumab

Drug Name: Omalizumab

Indication: For treatment of asthma caused by allergies



Pharmacology: Xolair inhibits the binding of IgE to the high-affinity IgE receptor (FceRI) on the surface of mast cells and basophils. Reduction in surface-bound IgE on FceRI-bearing cells limits the degree of release of mediators of the allergic response. Xolair is used to treat severe, persisten asthma.

Mechanism Of Action: Xolair binds to IgE (a class of antibodies normally secreted in allergic responses), which prevents their binding to mast cells and basophils.
