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 α3β4 receptors^[10]^[11]^[12] 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.^[13]
