藥物相互作用

• Atropine: Antagonizes the muscarinic effects of edrophonium. Concurrent use should be done cautiously as atropine can mask the early clinical signs of a cholinergic crisis.
• Dexpanthenol: Theoretically may have additive cholinergic effects when used with edrophonium.
• Digoxin: Edrophonium's cardiac effects may be increased; excessive slowing of heart rate (bradycardia) may occur.
• Depolarizing Muscle Relaxants (e.g., succinylcholine, decamethonium): Edrophonium may prolong the Phase I block of these agents.
• Non-depolarizing Muscle Relaxants (e.g., pancuronium, tubocurarine, vecuronium, atracurium): Edrophonium antagonizes the neuromuscular blocking actions of these agents.
