In this article, we assess the roles and the efficacy of immunopharmac
ologic agents in the treatment of multiple sclerosis (MS) and other de
myelinating disease syndromes. The initial clinical manifestations of
demyelinating disease, immunotherapeutic goals, efficacy of individual
agents, and specific immunopharmacologic recommendations are discusse
d. MS and other idiopathic demyelinating disease syndromes can be effe
ctively managed with immunotherapy. Exacerbations are treatable, and t
he frequency and severity of exacerbations can be reduced. Although so
me agents have a minor effect on progression of disability, current ap
proaches have not proved to have a major influence on treatment of pro
gressive MS. Immunotherapy for inflammatory demyelinating disease nece
ssitates a high degree of clinical certainty about the diagnosis. Beca
use all available therapeutic agents have limitations and significant
toxic effects, careful consideration is necessary before use, Treatmen
t should be individualized on the basis of the clinical course of the
disease and the degree of patient disability.
