POTASSIUM CHANNEL BLOCKER
Dalfampridine is a prescription medication approved by the U.S. Food and Drug Administration (FDA) to improve walking speed in adults with relapsing multiple sclerosis (MS). It is the first drug approved for this purpose. Dalfampridine is sold under the brand name Ampyra. Dalfampridine is not a cure for MS, but it can help reduce symptoms related to walking.
Dalfampridine is a potassium channel blocker. Dalfampridine is believed to work by blocking potassium channels on nerves, increasing conductivity of nerve signals. In other words, it improves communication routes between your brain and your body that are damaged by demyelination in MS.
