Purinergic receptor antagonism: A viable strategy for the management of autonomic dysreflexia?

The purinergic receptor ligand, ATP, may participate in reflex induced vasoconstriction through sympathetic efferent and sensory afferent mechanisms. However, the role of the purinergic system in contributing to autonomic dysreflexia following spinal cord injury is unclear. The present study investigates the involvement of P2X receptors in contributing to pressor responses during autonomic dysreflexia. Twenty rats were subjected to spinal cord injury and 24  h later hemodynamic responses to colorectal distension were recorded.
