Citalopram and its N-demethylated metabolites exist as a racemic mixture but its effects are largely due to the S-enantiomer, S-citalopram and S-demthylcitalopram. Despite distinct structural differences between compounds in this class, SSRIs possess similar pharmacological activity. As with other antidepressant agents, several weeks of therapy may be required before a clinical effect is seen. SSRIs are potent inhibitors of neuronal serotonin reuptake. They have little to no effect on norepinephrine or dopamine reuptake and do not antagonize α- or β-adrenergic, dopamine D<sub>2</sub> or histamine H<sub>1</sub> receptors. During acute use, SSRIs block serotonin reuptake and increase serotonin stimulation of somatodendritic 5-HT<sub>1A</sub> and terminal autoreceptors. Chronic use leads to desensitization of somatodendritic 5-HT<sub>1A</sub> and terminal autoreceptors. The overall clinical effect of increased mood and decreased anxiety is thought to be due to adaptive changes in neuronal function that leads to enhanced serotonergic neurotransmission. Side effects include dry mouth, nausea, dizziness, drowsiness, sexual dysfunction and headache. Side effects generally occur within the first two weeks of therapy and are usually less severe and frequent than those observed with tricyclic antidepressants. Citalopram is approved for treatment of depression. Unlabeled indications include mild dementia-associated agitation in nonpsychotic patients, smoking cessation, ethanol abuse, obsessive-compulsive disorder (OCD) in children, and diabetic neuropathy. Citalopram has the fewest drug-drug interactions of the SSRIs."@en ?g. }
