Use of Dalfampridine (Ampyra) Fact Sheet - Cleveland Clinic
It is an extended release form of 4-aminopyridine (4-AP, also known as fampridine). Dalfampridine is a broad-spectrum inhibitor of voltagesensitive potassium channels. In laboratory studies, dalfampridine has been found to improve impulse conduction in demyelinated nerve fibers and to increase synaptic transmitter release at nerve endings.
Aminopyridine - an overview | ScienceDirect Topics
There are two types: aminopyridine 3,4-diaminopyridine (3,4-DAP) and aminopyridine 4-aminopyridine (4-AP); the latter is lipid-soluble and crosses the blood–brain barrier more easily than 3,4-DAP.
4-Aminopyridine - an overview | ScienceDirect Topics
4-Aminopyridine is a highly ionized molecule that prolongs the repolarization phase of nerve and muscle action potentials by depressing the potassium current. It is used as an anticurare agent and enhances neuromuscular transmission by increasing the release of acetylcholine.
