Dalfampridine
Dalfampridine (pronounced dal-FAM-pri-deen), also known as 4-aminopyridine, is a medication used to improve walking in adults with certain types of multiple sclerosis (MS).
Etymology
The name "Dalfampridine" is derived from its chemical structure, which is a derivative of the organic compound pyridine. The prefix "Dal-" is an abbreviation of "diaminopyridine", indicating the presence of two amino groups in the pyridine ring.
Usage
Dalfampridine is an oral medication that works by blocking potassium channels on the surface of nerve fibers. This action can improve the conduction of nerve impulses in damaged nerves, potentially improving muscle strength and coordination.
