GHS Hazard Classification

Documented Uses

• Amifampridine is indicated for the symptomatic treatment of Lambert-Eaton myasthenic syndrome (LEMS) in adults and pediatric patients. Nevertheless, at the current time only the Firdapse brand of amifampridine is indicated for the treatment of LEMS in both adult and pediatric patients, while the Ruzurgi brand of amifampridine is indicated for the treatment of LEMS only in patients aged 6 to less than 17 years.
• Amifampridine is an orally available potassium channel blocker that increases acetylcholine in synaptic clefts of peripheral nerve endings and is used to treat the Lambert-Eaton myasthenic syndrome. Amifampridine is associated with a low rate of transient serum enzyme elevations during therapy but has not been linked with instances of clinically apparent acute liver injury.
• Breastfeeding; Lactation; Neuromuscular Agents; Potassium Channel Blockers;
• Drugs used for their actions on skeletal muscle. Included are agents that act directly on skeletal muscle, those that alter neuromuscular transmission (NEUROMUSCULAR BLOCKING AGENTS), and drugs that act centrally as skeletal muscle relaxants (MUSCLE RELAXANTS, CENTRAL). Drugs used in the treatment of movement disorders are ANTI-DYSKINESIA AGENTS.
• A class of drugs that act by inhibition of potassium efflux through cell membranes. Blockade of potassium channels prolongs the duration of ACTION POTENTIALS. They are used as ANTI-ARRHYTHMIA AGENTS and VASODILATOR AGENTS.
• Established Pharmacologic Class [EPC] – Potassium Channel Blocker
