Short Acting Logo


In adults, you may expect 15-20 minutes of neuromuscular blockade with MIVACRON¹*

*Range in clinical trials with 0.15 mg/kg dose: 9-38 minutes¹

The clinically effective duration for MIVACRON is one-third to one-half that of intermediate-acting agents¹

Summary of the pharmacodynamics of doses of MIVACRON ≥ED95; administered over 5-15 seconds during opioid/nitrous oxide/oxygen anesthesia: The mean time for spontaneous recovery of the twitch response from 25%-75% of control amplitude is about 6 minutes (range: 3 to 9 minutes, n=32) following an initial dose of 0.15 mg/kg MIVACRON and 7-8 minutes (range: 4 to 24 minutes, n=85) following initial doses of 0.2 or 0.25 mg/kg MIVACRON.¹

Safety Considerations1

MIVACRON is metabolized by plasma cholinesterase and should be used with great caution, if at all, in patients suspected of being homozygous for the atypical plasma cholinesterase gene due to the possibility of prolonged neuromuscular block. Plasma cholinesterase activity may be diminished in patients with genetic abnormalities of plasma cholinesterase, pregnancy, liver or kidney disease, malignant tumors, infections, burns, anemia, decompensated heart disease, peptic ulcer, or myxedema. The neuromuscular blocking effect of MIVACRON may be enhanced by drugs that reduce plasma cholinesterase activity (e.g., chronically administered oral contraceptives, glucocorticoids, or certain monoamine oxidase inhibitors) or by drugs that irreversibly inhibit plasma cholinesterase.
