Influence of trimedoxime bromide on degradation of benactyzine in acidic injectable solutions

open access: yesEuropean Journal of Pharmaceutical Sciences, 1999
The stability of benactyzine in a multicomponent injectable antidote formulation in deuterium oxide was studied in the presence of various concentrations of trimedoxime bromide. Benactyzine was found to be more stable in the absence of trimedoxime bromide and its degradation rate accelerated linearly with increasing concentrations of trimedoxime ...
