By selectively antagonizing TRPV1, CG5503 reduces the transmission of pain signals from peripheral nociceptors to the central nervous system. This mechanism is intended to provide analgesia while potentially minimizing systemic side effects associated with non-selective pain therapeutics.","oneSentence":"CG5503 is a selective inhibitor of
