Abstract | BACKGROUND AND PURPOSE: EXPERIMENTAL APPROACH: Rats were fed with 10% D-glucose for 12 weeks and effects of orally administered SSR240612 (0.3-30 mg kg(-1)) were determined on the development of tactile and cold allodynia. Possible interference of SSR240612 with vascular oxidative stress and pancreatic function was also addressed. KEY RESULTS: CONCLUSIONS AND IMPLICATIONS: We provide the first evidence that the B(1) receptors are involved in allodynia in an experimental rat model of insulin resistance. Allodynia was alleviated by SSR240612 most likely through a direct inhibition of B(1) receptors affecting spinal cord and/or sensory nerve excitation. Thus, orally active non- peptide B(1) receptor antagonists should have clinical therapeutic potential in the treatment of sensory polyneuropathy.
