Mechanism of Bepridil-Atracurium Interaction (Severity Level: Moderate)
Additive neuromuscular blocking effects Click to Show/Hide Mechanism Graph
Drug Name		Bepridil				Atracurium
Mechanism		Potentiates neuromuscular blockade				Neuromuscular blocking agent Neuronal acetylcholine receptor  Antagonist
Key Mechanism Factor 1
		Factor Name		Neuronal acetylcholine receptor				Structure Sequence
		Protein Family		Ligand-gated ion channel (TC 1.A.9) family
		Protein Function		After binding acetylcholine, the AChR responds by an extensive change in conformation that affects all subunits and leads to opening of an ion-conducting channel across the plasma membrane.     Click to Show/Hide
Mechanism Description		Additive neuromuscular blocking effects by the combination of Bepridil and Atracurium

Recommended Action
Management		Patients should be closely monitored for prolonged neuromuscular blockade. Reduced doses of muscle relaxants may be necessary. Profound neuromuscular blockade may be reversed by neostigmine or edrophonium.
