cisatracurium besylate Description

11 DESCRIPTION

Cisatracurium besylate is a nondepolarizing skeletal neuromuscular blocker for intravenous administration. Compared to other neuromuscular blockers, it is intermediate in its onset and duration of action.

Cisatracurium besylate is one of 10 isomers of atracurium besylate and constitutes approximately 15% of that mixture. Cisatracurium besylate is [1R-[1α,2α(1'R*,2'R*)]]-2,2'-[1,5-pentanediylbis[oxy(3-oxo-3,1-propanediyl)]]bis[1-[(3,4-dimethoxyphenyl)methyl]-1,2,3,4-tetrahydro-6,7-dimethoxy-2-methylisoquinolinium] dibenzenesulfonate.

The molecular formula of the cisatracurium parent bis-cation is C53H72N2O12 and the molecular weight is 929.2. The molecular formula of cisatracurium as the besylate salt is C65H82N2O18S2 and the molecular weight is 1243.5. The structural formula of cisatracurium besylate is:

Chemical Structure

The log of the partition coefficient of cisatracurium besylate is -2.12 in a 1-octanol/distilled water system at 25°C.

Cisatracurium Besylate Injection, USP is a sterile, non-pyrogenic aqueous solution provided in 5 mL, 10 mL, and 20 mL vials. The pH is adjusted to 3.0 to 3.8 with benzenesulfonic acid.

The 5 mL single-dose vials contain 2 mg/mL cisatracurium, equivalent to 2.68 mg/mL cisatracurium besylate.
The 10 mL multiple-dose vials contain 2 mg/mL cisatracurium, equivalent to 2.68 mg/mL cisatracurium besylate, and 0.9% benzyl alcohol as a preservative.
The 20 mL single-dose vials contain 10 mg/mL cisatracurium, equivalent to 13.38 mg/mL cisatracurium besylate.
