Indian Journal of PharmacologySummary: OBJECTIVES:
The goal of the research is to investigate the protocatechuic acid (PCA) potential action, a phenolic acid derivative, on pain induced by neuropathy and to determine its efficacy on activation of KATP type channels and A1 receptors.
MATERIALS AND METHODS:
Neuropathic pain by cause of sciatic nerve damage was induced in Sprague-Dawley rats. Anti-allodynic and anti-hyperalgesic effects were evaluated with von Frey apparatus and Hargreave's plantar test apparatus, respectively. The effects of PCA at the doses of 75, 150 and 300 mg/kg, carbamazepine at the doses of 50 and 100 mg/kg, combination of low effective doses of PCA and carbamazepine were tested. Pretreatments 3 μg/kg DPCPX as adenosine A1 receptor antagonist and 60.7 nmol glibenclamide as KATP channel blocker were applied for mechanistic studies.
RESULTS:
PCA showed anti-allodynic and anti-hyperalgesic effects without impairing locomotor activity. In addition, the combination treatment was found to be more effective than the separate individual treatments of drugs. KATP channel activation related with A1 receptor stimulation makes a significant contribution to the anti-allodynia and anti-hyperalgesia induced by PCA.
