Abstract
All neuromuscular blocking agents are characterised by the presence of quaternary ammonium groups. Such groups are essentially stable chemical functions. Thus, although quaternary ammonium compounds can be degraded to tertiary amines, in general this requires treatment with caustic alkali, i.e. approximately pH 14, at temperatures of around 100 °C (Hofmann 1851). It is not surprising, therefore, that the tetraalkylammonium group is not normally subject to biotransformation by the usual metabolic pathways of oxidation, reduction, hydrolysis, and conjugation in mammalian species. Consequently simple quaternary ammonium salts are excreted unchanged.
