Possible Interaction: Capsaicin and Phenoxybenzamine

Research Papers that Mention the Interaction

When applied after capsaicin, phenoxybenzamine inhibited thermal hyperalgesia at normal ambient temperatures, and during body warming and cooling.
When applied before capsaicin, phenoxybenzamine increased thermal hyperalgesia at normal ambient temperatures and during body warming.

The contractile response to capsaicin or neurokinin A of the rat isolated bladder were significantly reduced by incubation with phenoxybenzamine at a concentration reported to produce a selective alkylation of neurokinin-2 receptors, while the response to substance P or KCl was unaffected.
