Mechanism of action
OPC-14523 is a serotonin reuptake inhibitor. It treats depression, especially refractory depression, in a mammal, including a human, by administering to the mammal a sigma receptor ligand in combination with an antidepressant agent. It also relates to pharmaceutical compositions containing a pharmaceutically acceptable carrier, a sigma receptor ligand and a serotonin reuptake inhibitor.

Serotonin transporter whose primary function in the central nervous system involves the regulation of serotonergic signaling via transport of serotonin molecules from the synaptic cleft back into the pre-synaptic terminal for re-utilization. Plays a key role in mediating regulation of the availability of serotonin to other receptors of serotonergic systems. Terminates the action of serotonin an...
