an animal model (experimental autoimmune neuritis in rats) is often used for studies, and some agents have shown promise: glatiramer acetate, quinpramine, fasudil (an inhibitor of the rho-kinase enzyme), and the heart drug flecainide. an antibody targeted against the anti-gd3 antiganglioside antibody has shown benefit in laboratory research. given the role of the complement system in gbs, it has been suggested that complement inhibitors (such as the drug eculizumab) may be effective.
