(R)-Citalopram (oxalate)

(R)-Citalopram oxalate is an anticonvulsant, antidepressant and muscle relaxant. (R)-Citalopram oxalate is at least 20-fold weaker than S-citalopram (Escitalopram; HY-14258) as inhibitor of the 5-HT transporter (SERT). (R)-Citalopram oxalate functionally antagonises S-citalopram in vivo and in vitro. (R)-Citalopram oxalate has an effect on the association of Escitalopram with the high affinity primary site, and on its dissociation from the 5-HT transporter, via an allosteric mechanism.
