Substance P, a member of the tachykinin family, is a prosecretory neuropeptide distributed widely throughout the enteric nervous system. Implicated in inflammatory states, its role in enterotoxigenic water and electrolyte secretion is unclear. We assessed the effect of substance P antagonists and neurokinin receptor antagonists on cholera toxin-, Escherichia coli heat-labile enterotoxin (LT)-, and heat-stable enterotoxin (STa)-induced water secretion in an in vivo rat jejunal perfusion model.
