Clomipramine(Hydiphen, Anafranil base) blocks the production of norepinephrine in the central nervous system and 5-HT reuptake, thereby exerting sedative and anticholinergic effects, with IC50 of 1.5 nM. Clomipramine is also a non-selective monoamine reuptake inhibitor that can affect the transmission of multiple neurotransmitters.
