Cisatracurium hoffman elimination
WebHofmann elimination is a temperature- and pH-dependent process, and therefore atracurium's rate of degradation in vivo is highly influenced by body pH and temperature: An increase in body pH favors the elimination process, [39] [40] whereas a decrease in temperature slows down the process. [38] WebNov 25, 2012 · Hofmann elimination, an organ independent elimination pathway, occurs in plasma and tissue, and is responsible for approximately 77% of the overall …

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 are short-acting because they undergo spontaneous decomposition under physiologic conditions. We have all heard of the process termed a …
WebJan 22, 2024 · The Hofmann elimination process was enhanced, followed by a decrease in the cisatracurium concentration at the target organ in hyperthermia and respiratory/metabolic alkalosis conditions [8, 9]. Therefore, inadequate cisatracurium concentrations in target organs may contribute to a delay in respiratory management. WebThe mean CL values for cisatracurium ranged from 4.5 to 5.7 mL/min/kg in studies of healthy surgical patients. The compartmental PK modeling suggests that approximately 80% of the cisatracurium CL is accounted for by Hofmann elimination and the remaining 20% by renal and hepatic elimination.
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. WebMar 2, 2024 · Eliminated principally by Hofmann elimination (77–80%) and to lesser extent by renal and hepatic elimination (20%). Metabolites are eliminated principally by renal and hepatic elimination. Following administration of radiolabeled dose of cisatracurium to healthy individuals, 95% of administered dose is recovered in urine and 4% in feces; …
WebPlasma cisatracurium and metabolite concentration data collected in healthy adult patients receiving 0.1 or 0.2 mg *symbol* kg sup -1 doses of cisatracurium are consistent with data from in vitro experiments that suggest that Hofmann elimination is an important pathway for the elimination of cisatracurium.
