Abstract

Neuropathic pain (NP) is a complex and chronic disease caused by lesions or defects of the somatosensory nervous system. The treatments normally used for managing NP usually lack efficacy. Several animal models of NP have been engineered in order to understand the molecular mechanisms underlying NP and to find alternative molecules to use as new therapeutic agents. Preclinical in vivo studies identified the epigallocatechin-3-gallate (EGCG), a main active component of green tea (Camellia sinensis), as a possible therapeutic molecule for NP treatment due to its anti-inflammatory and antioxidant properties. Interestingly, it has been shown that EGCG reduced bone cancer pain. The purpose of this article is to discuss the potential use of EGCG for control and treatment of NP, by reviewing the preclinical studies reported in the literature and by shedding light on the potential schemes based on EGCG's application in clinical practices.

Keywords: EGCG; animal models of neuropathic pain; cancer bone pain; epigallocatechin-3-gallate; natural compound; neuropathic pain.
