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. WebCisatracurium is a relatively new NMB. Approximately 76.9% of the cisatracurium undergo Hoffman elimination which in turn depend on pH and body temperature. Cisatracurium also has other metabolisation pathways such as hepatic and renal elimination13,14. The purpose of our study was to compare the onset and the duration
WebThe degradation products of cistracurium were identified by ESI positive-ion detection as Hofmann elimination and ester hydrolysis products of cisatracurium. There were no propofol degradation products observed. The quantitation of the two drugs was accomplished using UV detection at 280 nm. As is evident with the parent molecule, atracurium, cisatracurium is also susceptible to degradation by Hofmann elimination and ester hydrolysis as components of the in vivo metabolic processes. See the atracurium page for information on Hofmann elimination in vivo versus the Hofmann degradation chemical reaction. Because Hofmann elimination is a temperature- and plasma pH-dependent process, cisatracuriu…
