Why was mivacurium discontinued?

Why was mivacurium discontinued?

In 2006, due to manufacturing problems, possibly related to an intermediary product’s availability, the supply of the drug to the U.S. ended. In part due to the imminent introduction of sugammadex in 2008, the decision was made to not pursue relicensing of mivacurium in the U.S. market.

What are the advantages of using mivacurium rather than succinylcholine?

In children, mivacurium produces complete neuromuscular blockade more slowly than does succinylcholine. During halothane anesthesia increasing the dose of mivacurium from 0.2 mg/kg to 0.3 mg/kg does not shorten the time to complete paralysis after mivacurium administration (1.5 minutes).

Is mivacurium short acting?

Mivacurium is the shortest-acting, nondepolarizing neuromuscular blocking agent available. Its advantages include a short duration of action and rapid metabolism by plasma cholinesterase.

What class of drug is mivacurium?

Mivacurium is a bisbenzylisoquinolinium based neuromuscular blocker or muscle relaxant.

Is Pavulon still used?

Pancuronium (trademarked as Pavulon) is an aminosteroid muscle relaxant with various medical uses. It is used in euthanasia and is used in some states as the second of three drugs administered during lethal injections in the United States.

Can you reverse mivacurium?

Conclusion: Recovery from a mivacurium chloride infusion is shorter by 3.6 minutes (margin of error +/- 3.3 minutes) when reversal with edrophonium/atropine is used. There is no difference in time to discharge from PACU and no evidence of differences in nausea and vomiting.

Does mivacurium release histamine?

Histamine is released by benzylisoquinolinium com- pounds such as mivacurium, atracurium and tubocurarine, causing skin flushing, decreases in arterial pressure and systemic vascular resistance and increases in heart rate [1–6].

How is mivacurium excreted?

The ED95 of mivacurium is 0.08 mg/kg and its in vitro elimination half-life is 3.1 minutes. Its short duration is due to metabolism by butyrylcholinesterase158,159 to quaternary amino alcohols and quaternary monoesters. These metabolites are excreted in the urine with half-lives of 90 minutes.

What is the half life of mivacurium?

It has a high potency and is devoid of cardiovascular effects. In adults, it has a low clearance (0.15 L/h/kg) and long elimination half-life (87 minutes). Mivacurium is a mixture of 3 stereoisomers.

What kind of drug is Pavulon?

Pavulon (pancuronium bromide) Injection is a neuromuscular blocking agent used to provide skeletal muscle relaxation during tracheal intubation and surgery. Pavulon is available in generic form.

Does neostigmine reverse Mivacurium?

Neostigmine reduces the duration of the neuromuscular block induced by mivacurium, By reducing the breakdown of acetylcholine, neostigmine induces an increase in acetylcholine in the synaptic cleft which competes for the same binding site as nondepolarizing neuromuscular blocking agents, and reverses the neuromuscular …
