How Does Ampyra Work?Ampyra blocks potassium channels. Potassium channels are found throughout the body and have several different functions, including playing an important role in how nerves work. It is thought that Ampyra helps nerve signals travel down the nerves that have been damaged by MS.

For instance, in one study, over 30 percent of people taking Ampyra had a 20 percent or greater increase in walking speed, compared to only about 10 percent of people taking a placebo (a "sugar pill" with no active ingredients).
