Escitalopram oxalate (Cat. No: A000710) is a new type of SSRIS drug, which mainly mediates the inhibitory effect of citalopram on 5-HT reuptake, and has a high affinity for low affinity allosteric binding sites. It has become the first-line drug for the treatment of depression by inhibiting 5-HT transporter (SERT) in a highly selective dose-dependent manner and inhibiting 5-HT reuptake in the presynaptic membrane of nerve endings in the central nervous system.
