Amifampridine is a potassium channel blocker. Its mechanism of action involves inhibiting the outward flow of potassium ions, prolonging the duration of action potentials, and increasing the inward flow of calcium ions. This effect enhances the conduction function of the neuromuscular junction, restores the contractility of muscle fibers, and improves symptoms of muscle weakness.
