PURPOSE The phosphodiesterase 5 inhibitor sildenafil has antinociceptive effects, mediated by an increase in cGMP. This study examined the role of spinal adenosine and serotonin receptors played in the antinociceptive effects of intrathecal sildenafil. MATERIALS AND METHODS Intrathecal catheters were inserted into the subarachnoid space of Sprague-Dawley male rats as a drug delivery device. P...
