ABT-418 is a drug developed by Abbott, that has nootropic, neuroprotective and anxiolytic effects,[1][2][3][4][5] and has been researched for treatment of both Alzheimer's disease[6] and ADHD.[7][8][9] It acts as an agonist at neural nicotinic acetylcholine receptors, subtype-selective binding with high affinity to the α4β2, α7/5-HT3, and α2β2 nicotinic acetylcholine receptors but not the α3β4 subtype[10][11] familiar to nicotine. ABT-418 was reasonably effective for both applications and fairly well tolerated, but produced some side effects, principally nausea, and it is unclear whether ABT-418 itself will proceed to clinical development or if another similar drug will be used instead.[12]
