sugammadex 

Indicated for Reversal of Neuromuscular Blockers:


Adults having surgery may use a selective relaxant binding agent to reverse neuromuscular blockade (NMB) brought on by rocuronium or vecuronium.
Administer as a single intravenous bolus infusion into an existing intravenous line over 10 seconds.

For vecuronium and rocuronium
After vecuronium or rocuronium-induced neuromuscular blockade, a dosage of 4 mg/kg is advised if spontaneous recovery of the twitch response remains below 1 to 2 post-tetanic counts (PTC) or if there are no twitching responses to train-of-four (TOF) stimulation.
After vecuronium or rocuronium-induced neuromuscular blockade, a dosage of 2 mg/kg is advised if spontaneous recovery has progressed to the re-emergence of the following twitch (T2) in response to TOF stimulation.

For rocuronium only
If reversing neuromuscular blockade is clinically necessary and must be done quickly (within 3 minutes), 16 mg/kg of rocuronium is administered.
The effectiveness of the 16-mg/kg dosage given after vecuronium administration has yet to be investigated.
