Abstract:
In decerebrate, spinalized, unanesthetized rats, 37 pmol (10 ng) intrathecally injected clonidine facilitated the flexor reflex. This effect was blocked by the specific tachykinin antagonists CP-96,345, which acts at the NK1 receptor, and Men 10207, which acts at the NK2 receptor. Thus, low-dose intrathecal clonidine releases the tachykinins substance P and neurokinin A in the spinal cord.
