Mechanism of Methoxyflurane-Mivacurium Interaction (Severity Level: Moderate)
Additive neuromuscular blocking effects Click to Show/Hide Mechanism Graph
Drug Name		Methoxyflurane				Mivacurium
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 Methoxyflurane and Mivacurium

Recommended Action
Management		The muscle relaxant dosage may need to be reduced when inhalation anesthetics are used, especially during longer procedures. In general, inhalation anesthetics should be administered only by health care providers specially trained in the use of these agents and in the care of anesthetized patients.
