How can toremifene taken on the day of surgery affect reversal of neuromuscular blockade by sugammadex sodium?

Toremifene taken on the day of surgery may, through its relatively high binding affinity and potentially high plasma concentrations, displace rocuronium or vecuronium from complexes with Bridion (sugammadex sodium), delaying recovery of the T₄/T₁ ratio to 0.9.
