Scientific Name: Amifampridine
Brand Name: Firdapse, Ruzurgi
Company Owner: Not Available
Mechanism Of Action Amifampridine is a symptomatic treatment that increases acetylcholine concentrations at the neuromuscular junction. It selectively blocks presynaptic fast voltage-gated potassium channels, thereby prolonging cell membrane depolarization and action potential, and augmenting calcium transport into the nerve endings. Increased intracellular calcium enhances the exocytosis of acetylcholine-containing vesicles and enhances impulse transmission at central, autonomic, and neuromuscular synapses
Description of the Drug: Amifampridine is a voltage gated potassium channel blocker used to treat Lambert-Eaton myasthenic syndrome.
