Mechanism of action

Fampridine is a broad-spectrum potassium channel blocker that increases the duration of the action potential in demyelinated nerve fibers, thereby improving conduction across damaged segments. The sustained-release formulation allows for twice-daily dosing with improved tolerability compared to immediate-release formulations. This mechanism is particularly beneficial in demyelinating diseases where nerve conduction is impaired.
