Abstract

A new technique involving the use of [125I]labeled rose bengal for the quantification of pipecuronium bromide (a muscle relaxant drug) is presented. This technique, which is based on the ability of rose bengal to react with pipecuronium and then form a complex which can be extracted into an organic solvent, involves two steps : the purification and labeling of rose bengal with 125I, and the quantification of pipecuronium. The specific activity of the compound (106 μCi/mg) allows for the quantification of pipecuronium in biological samples at concentrations as low as 5 ng/ml.
