Comparative Study
Discrepancy of recovery times related to potency between atracurium and mivacurium simultaneously administered in isolated forearms.
Recovery from potent non-depolarising muscle relaxants is slower than from the less potent agents. However, recovery from mivacurium, which is more potent than atracurium, is faster than from atracurium following systemic administration. ⋯ In these experiments, the recovery times from maximum block to 50% recovery of control twitch height were significantly longer with mivacurium than with atracurium (mean 25.2(SD 4.7) versus 22.6(3.1) min, p < 0.01). We found that the evidence that mivacurium has a slower recovery than the less potent atracurium may be true using the bilateral, isolated forearm technique and that the discrepancy might be due to a difference in the pharmacokinetic variables of the two drugs.
