Sugammadex: a review of its use in anaesthetic practice

Abstract

Sugammadex (Bridion), a modified gamma-cyclodextrin, is the first selective relaxant binding agent indicated to reverse the neuromuscular blockade induced during general anaesthesia to facilitate surgical procedures. The mechanism of action of sugammadex differs from that of other commonly used reversal agents, such as neostigmine and edrophonium. In the EU, sugammadex is recommended for use in the reversal of rocuronium- or vecuronium-induced moderate or deep muscle relaxation in adult (including elderly) patients and reversal of rocuronium-induced moderate muscle relaxation in paediatric patients (aged 2-17 years). Sugammadex is also approved in Australia, Iceland, New Zealand and Norway. In clinical trials in adult surgical patients with relatively good health, sugammadex at recommended doses provided rapid reversal of rocuronium- or vecuronium-induced neuromuscular blockade with a low incidence of residual or recurrent neuromuscular blockade and was generally well tolerated. In paediatric patients, sugammadex effectively reversed rocuronium-induced neuromuscular blockade and was generally well tolerated. Several factors associated with the use of sugammadex have yet to be determined, such as the efficacy and safety in patients with poorer health or in those with neuromuscular disorders, the incidence of infrequent adverse events in larger patient populations and the cost effectiveness of the drug relative to existing reversal agents. Nevertheless, sugammadex is a useful addition to the reversal agents commonly employed in anaesthetic practice.
