WebAtracurium is a new neuromuscular blocking agent which has an unique mode of elimination by spontaneous degradation in slightly alkali solution, according to the Hofmann elimination. The Hofmann elimination is completed in plasma (in vitro or in vivo) by an ester hydrolysis. The major degradation product is laudanosine. WebNOTE: Cisatracurium is not recommended for rapid-sequence intubation due to the time required for its onset of action. Intravenous dosage. Adults. 0.15 to 0.2 mg/kg/dose IV. Doses up to 0.4 mg/kg have been used. Onset of intubating conditions is 2 minutes. Coadministration of certain drugs may need to be avoided or dosage adjustments may be ...
WebDec 11, 2024 · For atracurium and cisatracurium, their Hoffman elimination produces the metabolite laudanosine. If allowed to build up like in cases of hepatic failure, this metabolite can cause central nervous system (CNS) excitation to the point of seizure activity. Pancuronium, which is normally eliminated via deacetylation by hepatocytes, can … WebThis agent is especially good for patients that have compromised renal/hepatic failure. This is because it relies on Hofmann elimination and ester hyrolysis to be metabolized. …
WebCisatracurium and atracurium share the same metabolic pathways, but Hofmann elimination may have a greater role in the elimination of cisatracurium than in atracurium [2, 4–7]. Spontaneous in vivo degradation accounts for 77% of total body clearance of cisatracurium [6]. Organ clearance is 23% of total body clearance.
