Phenylephrine-induced antinociception: investigations of potential neural and endocrine bases.


Acute hypertensive states can produce antinociception, largely via unknown mechanisms. The aim of the present series of experiments was to examine potential hormonal and neural bases of analgesia induced by i.v. infusion of the pressor (hypertensive) agent phenylephrine. All rats were implanted with right jugular and left carotid cannulae for phenylephrine… (More)
