Amifampridine
A potassium channel blocker that prolongs nerve action potentials, thereby increasing acetylcholine release at neuromuscular junctions, used to treat Lambert-Eaton myasthenic syndrome (LEMS), a rare autoimmune neuromuscular disorder. By compensating for the impaired nerve-to-muscle signaling caused by autoantibodies in LEMS, it improves muscle strength.
