Citalopram impurity standard

Escitalopram oxalate is a synthetic drug that is the active ingredient in Lexapro. Escitalopram oxalate is used to treat major depressive disorder, generalized anxiety disorder, and panic disorder. It is a racemic mixture of two enantiomers, 1-[3-(dimethylamino)propyl]-1-(4-fluorophenyl)-1,3-dihydro-5-isobenzofurancarboxamide and 1-[3-(dimethylamino)propyl]-1-(4-methoxyphenyl)-1,3-dihydro-5-isobenzofurancarboxamide. Escitalopram oxalate binds reversibly to the serotonin transporter on the presynaptic cell membrane and increases serotonin concentration in the synapse. The effective dose for escitalopram oxalate ranges from 10 mg to 20 mg per day. Clinical trials have shown that escital
