Beyond the hype: Understanding the limitations of sugammadex.

Abstract

PURPOSE: Sugammadex rapidly and effectively reverses aminosteroidal neuromuscular blocking agents and has largely replaced neostigmine in perioperative practice. Although its use is associated with faster recovery and a lower rate of residual neuromuscular blockade, clinically important limitations exist. This review summarizes the literature describing incomplete reversal, recurrence of neuromuscular blockade, adverse effects, drug interactions, and challenges in special populations, with a focus on the role of quantitative neuromuscular monitoring and pharmacist-led activities to optimize sugammadex use.

SUMMARY: While sugammadex substantially reduces the risk of residual neuromuscular blockade compared to neostigmine, incomplete reversal and recurrence of neuromuscular blockade continue to occur, particularly when dosing is not guided by quantitative neuromuscular monitoring. Underdosing, redistribution of neuromuscular blocking agents, and altered pharmacokinetics can all contribute to inconsistent responses. Quantitative neuromuscular monitoring, rather than choice of reversal agent, is the main determinant of reliable neuromuscular recovery and reduced occurrence of postoperative complications. Sugammadex is associated with rare but potentially serious adverse effects, including hypersensitivity reactions and cardiovascular instability, highlighting the need for careful monitoring. Patent expiration and generic availability may expand access to sugammadex, and these limitations warrant continued attention.

CONCLUSION: Sugammadex represents a major advance in neuromuscular blockade reversal but remains an imperfect agent. Safe and effective use requires individualized dosing guided by quantitative neuromuscular monitoring and vigilance for adverse effects. Pharmacists are well positioned to lead education, dosing protocol development, and monitoring strategies that optimize patient safety while supporting adoption of quantitative neuromuscular monitoring.
