|Title:||Neuromuscular blocking agents|
|Abstract:||1R-cis,1'R-cis isomer of a 2',2'-(3,11-dioxo-4,10-dioxatridecylene)-bis(1,2,3,4-tetrahydro-6, 7-dimethoxy-2-methyl-1-veratrylisoquinolium) said, substantially free from other geometrical and optical isomers thereof. The 1R-cis,1'R-cis isomer has been found to have an advantageous combination of pharmacological properties, notably greater neuromuscular blocking potency, weaker histamine-releasing potency, and at equivalent levels of neuromuscular blockade, fewer potential adverse effects on the autonomic nervous system (sympathetic and parasympathetic blockage), in comparison with the known mixture of geometrical and optical isomers.|
