Tebanicline

Tebanicline (ebanicline, ABT-594) is a potent synthetic nicotinic (non-opioid) analgesic drug developed by Abbott. It was developed as a less toxic analog of the potent poison dart frog-derived compound epibatidine, which is about 200 times stronger than morphine as an analgesic, but produces extremely dangerous toxic side effects.[1][2] Like epibatidine, tebanicline showed potent analgesic activity against neuropathic pain in both animal and human trials, but with far less toxicity than its parent compound.[3][4][5][6][7][8] It acts as a partial agonist at neuronal nicotinic acetylcholine receptors, binding to both the α3β4 and the α4β2 subtypes.[9]

Tebanicline progressed to Phase II clinical trials in humans,[10] but was dropped from further development due to unacceptable incidence of gastrointestinal side effects.[11] However, further research in this area is ongoing,[12][13][14][15] and the development of nicotinic acetylcholine receptor agonists is ongoing.[16][17][18][19] No agents from this class have successfully completed human clinical trials due to their unacceptable side effect profiles. Research in the area continues.[20]
