Figure 4. Concentrations of the two potent stereoisomers of mivacurium before and after 50 micro gram/kg neostigmine or 125-2,000 micro gram/kg edrophonium antagonism. Values are mean, SD for each stereoisomer and are normalized to the plasma concentration before the antagonist. For edrophonium, the magnitude of the peak increase in mivacurium concentrations did not correlate with edrophonium dose.
