title: Determination of pipecurium bromide, a new non-depolarizing neuromuscular blocking agent, in human serum.
abstract: A method for the determination of 2 beta, 16 beta-bis (4'dimethyl-1'-piperazino)-3a, 17 beta-diacetoxy-5 alpha-androstane is described. After deproteinization a pipecurium bromide Rose Bengal complex is formed and extracted with chloroform from a mildly basic medium. The amount of pipecurium bromide is proportional to the amount of Rose Bengal in the complex, and the quantity of the latter can easily be determined by measuring its iodine content. The method is sufficiently sensitive to be used for the analysis of human serum.
