RT Journal Article SR Electronic T1 Omalizumab: Where does it fit into current asthma management? JF Cleveland Clinic Journal of Medicine JO Cleve Clin J Med FD Cleveland Clinic SP 251 OP 261 VO 71 IS 3 A1 Rambasek, Todd E. A1 Lang, David M. A1 Kavuru, Mani S. YR 2004 UL http://www.ccjm.org/content/71/3/251.abstract AB Omalizumab (Xolair), a monoclonal antibody, is a new agent that blocks the allergic cascade at its primary step. This drug offers substantial promise for patients with moderate-to-severe, persistent allergic asthma that is not well controlled. But due to the cost of the drug, limitations on dosage, and available clinical trial data, it is not a first-line therapy. This review discusses how this drug works, which patients will be candidates for it, and the practical aspects of using it.
