Dalfampridine (Ampyra®) is an oral medication, in tablet form, which blocks tiny pores, or potassium channels, on the surface of nerve fibers. Blocking potassium channels may improve the conduction of nerve signals in along nerve fibers whose insulating myelin coating has been damaged by MS.
Dalfampridine is approved by the U.S. Food and Drug Administration (FDA) to improve walking in patients with multiple sclerosis, as demonstrated by an increase in walking speed.
