12.1 Mechanism of Action The mechanism of action of citalopram is unclear, but is presumed to be related to potentiation of serotonergic activity in the central nervous system (CNS) resulting from its inhibition of CNS neuronal reuptake of serotonin (5-HT).

Citalopram tablets are indicated for the treatment of major depressive disorder (MDD) in adults [see Clinical Studies (14) ] . Citalopram tablets are a selective serotonin reuptake inhibitor (SSRI) indicated for the treatment of major depressive disorder (MDD) in adults ( 1 ) .

Administer once daily with or without food ( 2 ) . Initial dosage is 20 mg once daily; after one week may increase to maximum dosage of 40 mg once daily ( 2.1 ). Patients greater than 60 years of age, patients with hepatic impairment, and CYP2C19 poor metabolizers: maximum recommended dosage is 20 mg once daily ( 2.2 ). When discontinuing citalopram tablets, reduce dosage gradually ( 2.4 , 5.6 ). 2.1 Recommended Dosage Administer citalopram tablets once daily, with or without food, at an initial dosage of 20 mg once daily, with an increase to a maximum dosage of 40 mg once daily at an interval of no less than one week. Dosages above 40 mg once daily are not recommended due to the risk of QT prolongation [see (5.2) ] . 2.2 Screen for Bipolar Disorder Prior to Starting Citalopram Tablets Prior to initiating treatment with citalopram tablets or another antidepressant, screen patients for a personal or family history of bipolar disorder, mania, or hypomania [See (5.5) ]. 2.3 Recommended Dosage for Specific Populations The maximum recommended dosage of citalopram tablets for patients who are greater than 60 years of age, patients with hepatic impairment, and for CYP2C19 poor metabolizers is 20 mg once daily [see (5.2) , Clinical Pharmacology (12.3) ]. 2.4 Dosage Modifications with Concomitant Use of CYP2C19 Inhibitors The maximum recommended dosage of citalopram tablets when used concomitantly with a CYP2C19 inhibitor is 20 mg once daily [see (5.2) , (7) ]. 2.5 Switching Patients to or from a Monoamine Oxidase Inhibitor Antidepressant At least 14 days must elapse between discontinuation of a monoamine oxidase inhibitor (MAOI) antidepressant and initiation of therapy with citalopram tablets. Conversely, at least 14 days must elapse after stopping citalopram tablets before starting an MAOI antidepressant [see (4) and (5.3) ] . 2.6 Discontinuing Treatment with Citalopram Tablets may occur upon discontinuation of citalopram tablets [see (5.6) ] . Gradually reduce the dosage rather than stopping citalopram tablets abruptly whenever possible.

The following are discussed in greater detail in other sections of the labeling: Hypersensitivity reactions [see (4) ] Suicidal thoughts and behaviors in adolescents and young adults [see (5.1) ] QT-prolongation and torsade de pointes [see (5.2) ] Serotonin syndrome [see (5.3) ] Increased risk of bleeding [see (5.4) ] Activation of mania or hypomania [see (5.5) ] Discontinuation syndrome [see (5.6) ] Seizures [see (5.7) ] Angle-closure glaucoma [see (5.8) ] Hyponatremia [see (5.9) ] Sexual Dysfunction [see (5.10) ] Most common adverse reaction (incidence ≥ 5% and twice placebo) is ejaculation disorder (primarily ejaculation delay) ( 6.1 ) .

The safety for citalopram included citalopram exposures in patients and/or healthy subjects from 3 different groups of studies: 429 healthy subjects in clinical pharmacology/pharmacokinetic studies; 4,422 exposures from patients in controlled and uncontrolled clinical trials, corresponding to approximately 1,370 patient-exposure years. There were, in addition, over 19,000 exposures from mostly open-label, European postmarketing studies. The conditions and duration of treatment with citalopram varied greatly and included (in overlapping categories) open-label and double-blind studies, inpatient and outpatient studies, fixed-dose and dose-titration studies, and short-term and long-term exposure. Associated with Discontinuation of Treatment Among 1,063 patients with MDD who received citalopram at doses ranging from 10 mg to 80 mg once daily in placebocontrolled trials of up to 6 weeks duration, 16% discontinued treatment due to an adverse reaction, as compared to 8% of 446 patients receiving placebo. The associated with discontinuation (i.e., associated with discontinuation in at least 1% of citalopram-treated patients at a rate at least twice that of placebo) are shown in Table 2 . Table 2: Associated with Discontinuation of Citalopram Treatment in Short-Term, Placebo-Controlled MDD Trials * A patient can report more than one reason for discontinuation and be counted more than once in this table....

Citalopram tablets are contraindicated in patients: taking, or within 14 days of stopping, MAOIs (including MAOIs such as linezolid or intravenous methylene blue) because of an increased risk of serotonin syndrome [see (5.3) , (7) ] . taking pimozide because of risk of QT prolongation [see (7) ] . with known hypersensitivity to citalopram or any of the inactive ingredients in citalopram tablets. Reactions have included angioedema and anaphylaxis [see (6.2) ]. Concomitant use of monoamine oxidase inhibitors (MAOIs) or use within 14 days of discontinuing a MAOI ( 4 ). Concomitant use of pimozide ( 4 ). Known hypersensitivity to citalopram or any of the inactive ingredients of citalopram ( 4 ).
