nAChR
Sugammadex has a high affinity for Pipecuronium bromide. As Pipecuronium bromide is about 6 to 7 times more potent than Rocuronium, fewer molecules are required to achieve a comparative blockade than in the case of Rocuronium.
The average ED
95
is 0.045mg/kg (0.035-0.059 mg/kg) of Pipecuronium bromide, the onset of action varies between 2 and 6.3 minutes, depending on the dose and the background anesthesia. Pipecuronium bromide does not liberate histamine, it has no cardiovascular side effects even in doses of 3× ED
95
, and anaphylaxis does not appear to be a problem.
Carboxymethylated γ-cyclodextrin shows efficient and complete reversal of the Pipecuronium bromide induced neuromuscular block in an ex vivo rat diaphragm experiment.
