Gamma-aminobutyric acid (GABA) is an inhibitory neurotransmitter, and one would imagine that if one can increase inhibition in the pain pathways, you might reduce pain. Tackling GABA has been a bit disappointing, I must say, but it, at least, is a potential target for neuropathic pain. The sodium channels on the axons can also be blocked, reducing both peripheral and centr
