CITALOPRAM

Citalopram Capsules contain citalopram, a selective serotonin reuptake inhibitor (SSRI). Citalopram hydrobromide is a racemic bicyclic phthalane derivative designated (±)-1-(3-dimethylaminopropyl)-1-(4-fluorophenyl)-1,3-dihydroisobenzofuran-5carbonitrile, hydrobromide with the following structural formula: The molecular formula is C 20 H 22 BrFN 2 O and its molecular weight is 405.35. Citalopram hydrobromide is a white to almost white crystalline powder. Citalopram hydrobromide is freely soluble in chloroform and sparingly soluble in ethanol and water. Citalopram Capsules is for oral administration and contains 30 mg of citalopram, equivalent to 37.5 mg of citalopram hydrobromide. The strengths reflect citalopram base equivalent content. Citalopram Capsules also contain the inactive ingredients copovidone, croscarmellose sodium, gelatin, magnesium stearate, microcrystalline cellulose, talc and titanium dioxide. The capsule shells contain the colorants FD&C Blue #1 and FD&C Red #3.

Citalopram Capsules are indicated for the treatment of Major Depressive Disorder (MDD) in adults [see Clinical Studies ( 14 )] . Citalopram Capsules is a selective serotonin reuptake inhibitor (SSRI) indicated for treatment of Major Depressive Disorder (MDD) in adults. ( 1 )

Do not initiate treatment with Citalopram Capsules. Use another citalopram product for initial dosage titration or dosages other than 30 mg once daily. ( 2.1 ) Administer once daily with or without food. ( 2.1 ) Recommended dosage of Citalopram Capsules is 30 mg once daily. ( 2.1 ) Citalopram dosages above 40 mg once daily are not recommended due to the risk of QT prolongation. ( 2.1 ) When discontinuing Citalopram Capsules, reduce dose gradually. Gradual dosage reduction will require use of another citalopram product. ( 2.4 , 5.6 ) 2.1 Recommended Dosage Do not initiate treatment with Citalopram Capsules because the only available dose strength is 30 mg. Use another citalopram product for initial dosage, titration, and dosages other than 30 mg once daily. Refer to Prescribing Information of the other citalopram products for the recommended dosage for those products. Administer Citalopram Capsules orally, once daily, with or without food. Citalopram should be administered at an initial dose of 20 mg once daily, with an increase to a maximum dose of 40 mg once daily at an interval of no less than one week. Citalopram dosages above 40 mg once daily are not recommended due to the risk of QT prolongation [see Warnings and Precautions ( 5.2 )] . 2.2 Screen for Bipolar Disorder Prior to Starting Citalopram Capsules Prior to initiating treatment with Citalopram Capsules or another antidepressant, screen patients for a personal or family history of bipolar disorder, mania, or hypomania [see Warnings and Precautions ( 5.5 )] . 2.3 Switching Patients to or from a Monoamine Oxidase Inhibitor Antidepresssant At least 14 days must elapse between discontinuation of an monoamine oxidase inhibitor (MAOI) and initiation of therapy with Citalopram Capsules. Conversely, at least 14 days must elapse after stopping Citalopram Capsules before starting an MAOI antidepressant [see Contraindications ( 4 ), Warnings and Precautions ( 5.3 )] . 2.4 Discontinuing Treatment with Citalopram Capsules Adverse reactions may occur upon discontinuation of Citalopram Capsules [see Warnings and Precautions ( 5.6 )] . Gradually reduce the dosage rather than stopping Citalopram Capsules abruptly whenever possible. Given that 30 mg is only available dosage strength of Citalopram Capsules, gradual dosage reduction will require the use of another citalopram product.

Citalopram Capsules is 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 Warnings and Precautions ( 5.3 ), Drug Interactions ( 7 )] . taking pimozide because of risk of QT prolongation [see Drug Interactions ( 7 )] . with known hypersensitivity to citalopram or any of the inactive ingredients in Citalopram Capsules. Reactions have included angioedema and anaphylaxis [see Adverse Reactions ( 6.2 )] . Concomitant use of monoamine oxidase inhibitors (MAOIs) or use within 14 days of discontinuing an MAOI. ( 4 ) Concomitant use of pimozide. ( 4 ) Known hypersensitivity to citalopram or any of the inactive ingredients of Citalopram Capsules. ( 4 )

The safety of Citalopram Capsules for the treatment for major depressive disorder (MDD) in adults is based upon adequate and well-controlled studies of another citalopram product. The results of these adequate and well-controlled studies of citalopram are presented below. The safety for citalopram included 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. Adverse Reactions 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 placebo-controlled trials of up to 6 weeks in duration, 16% discontinued treatment due to an adverse reaction, as compared to 8% of 446 patients receiving placebo. The adverse reactions 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: Adverse Reactions Associated with Discontinuation of Treatment in Short-Term, Placebo-Controlled, Depression Trials * A patient can report more than one reason for discontinuation and be counted more than once in this table. Body System/Adverse Reaction Citalopram* (N=1,063) % Placebo (N=446) % General Asthenia 1 <1 Gastrointestinal Disorders Nausea 4 0 Dry Mouth 1 <1 Vomiting 1 0 Central and Peripheral Nervous System Disorders Dizziness 2 <1 Psychiatric Disorders Insomnia 3 1 Somnolence 2 1 Agitation 1 <1 Table 3 enumerates adverse reactions that occurred among 1,063 patients with MDD who received citalopram at doses ranging from 10 mg to 80 mg once daily in placebo-controlled trials of up to 6 weeks in duration. The most common adverse reaction that occurred in citalopram-treated patients with an incidence of 5% or greater and at least twice the incidence in placebo patients was ejaculation disorder (primarily ejaculatory delay) in male patients, see Table 3. Table 3: Adverse Reactions (≥2% and Greater than Placebo) Among Citalopram-treated Patients* * Except for the following adverse reactions which had an incidence on placebo. Citalopram: headache, asthenia, dizziness, constipation, palpitation, vision abnormal, sleep disorder, nervousness, pharyngitis, micturition disorder, back pain. 1 Denominator used was for females only (N=638 citalopram; N=252 placebo). 2 Primarily ejaculatory delay. 3 Denominator used was for males only (N=425 citalopram; N=194 placebo).

A positive dose response (p<0.05) for the following adverse reactions: fatigue, impotence, insomnia, sweating increased, somnolence, and yawning. Male and Female Sexual Dysfunction with SSRIs Although changes in sexual desire, sexual performance, and sexual satisfaction often occur as manifestations of a psychiatric disorder, they may also be a consequence of SSRI treatment. However, reliable estimates of the incidence and severity of untoward experiences involving sexual desire, performance, and satisfaction are difficult to obtain, in part because patients and health care providers may be reluctant to discuss them. Accordingly, estimates of the incidence of untoward sexual experience and performance cited in product labeling are likely to underestimate their actual incidence. Table 4 below displays the incidence of sexual side effects reported by at least 2% of male patients taking citalopram in a pool of placebo-controlled clinical trials in patients with depression. Table 4: Adverse Reactions (≥2%) Related to Sexual Dysfunction in Citalopram-treated Male Patients in Pooled Placebo-Controlled Clinical Trials of MDD Treatment Citalopram Placebo n (males) 425 (%) 194 (%) Abnormal Ejaculation (mostly ejaculatory delay) 6.1 1 Libido Decreased 3.8 <1 Impotence 2.8 <1 In female depressed patients receiving citalopram, the reported incidence of decreased libido and anorgasmia was 1.3% (n=638 females) and 1.1% (n=252 females), respectively. Weight Changes Patients treated with citalopram in controlled trials experienced a weight loss of about 0.5 kg compared to no change for placebo patients. ECG Changes In a thorough QT study, citalopram was found to be associated with a dose-dependent increase in the QTc interval. Electrocardiograms from citalopram (N=802) and placebo (N=241) groups were compared with respect to outliers defined as subjects with QTc changes over 60 msec from baseline or absolute values over 500 msec post-dose, and subjects with heart rate increases to over 100 bpm or decreases to less than 50 bpm with a 25% change from baseline (tachycardic or bradycardic outliers, respectively). In the citalopram group 1.9% of the patients had a change from baseline in QTcF >60 msec compared to 1.2% of the patients in the placebo group. None of the patients in the placebo group had a post-dose QTcF >500 msec compared to 0.5% of the patients in the citalopram group. The incidence of tachycardic outliers was 0.5% in the citalopram group and 0.4% in the placebo group. The incidence of bradycardic outliers was 0.9% in the citalopram group and 0.4% in the placebo group.

Table 5 presents clinically important drug interactions with Citalopram Capsules. CYP2C19 inhibitors and CYP2C19 poor metabolizers: Avoid concomitant use. There is an increased risk of QT prolongation with concomitant use. ( 7 ) Table 5: Clinically Important Drug Interactions with Citalopram Capsules Monoamine Oxidase Inhibitors (MAOIs) Clinical Impact: Concomitant use of SSRIs, including Citalopram Capsules, and MAOIs increases the risk of serotonin syndrome. Intervention: Citalopram Capsules is contraindicated in patients taking MAOIs, including MAOIs such as linezolid or intravenous methylene blue [see Dosage and Administration ( 2.3 ), Contraindications ( 4 ), Warnings and Precautions ( 5.3 )] . Pimozide Clinical Impact: Concomitant use of citalopram with pimozide increases plasma concentrations of pimozide, a drug with a narrow therapeutic index, and may increase the risk of QT prolongation and/or ventricular arrhythmias compared to use of citalopram alone [see Clinical Pharmacology ( 12.3 )]. Intervention: Citalopram Capsules is contraindicated in patients taking pimozide [see Contraindications ( 4 ), Warnings and Precautions ( 5.2 )] . Drugs that Prolong the QTc Interval Clinical Impact: Concomitant use of citalopram with drugs that prolong QT can cause additional QT prolongation compared to the use of citalopram alone [see Clinical Pharmacology ( 12.3 )]. Intervention: Avoid concomitant use of Citalopram Capsules with drugs that prolong the QT interval (Citalopram Capsules is contraindicated in patients taking pimozide) [see Contraindications ( 4 ), Warnings and Precautions ( 5.2 )] . CYP2C19 Inhibitors Clinical Impact: Concomitant use of citalopram with CYP2C19 inhibitors increases the risk of QT prolongation and/or ventricular arrhythmias compared to the use of citalopram alone [see Clinical Pharmacology ( 12.3 )]. Intervention: Avoid concomitant use of Citalopram Capsules with CYP2C19 inhibitors [see Warnings and Precautions ( 5.2 )]. Other Serotonergic Drugs Clinical Impact: Concomitant use of Citalopram Capsules with other serotonergic drugs (including other SSRIs, SNRIs, triptans, tricyclic antidepressants, opioids, lithium, buspirone, amphetamines, tryptophan, and St. John's Wort) increases the risk of serotonin syndrome. Intervention: Monitor patients for signs and symptoms of serotonin syndrome, particularly during Citalopram Capsules initiation and changes in citalopram dosage. If serotonin syndrome occurs, consider discontinuation of Citalopram Capsules and/or concomitant serotonergic drugs [see Dosage and Administration ( 2.1 , 2.4 ), Warnings and Precautions ( 5.3 )] . Drugs That Interfere With Hemostasis (antiplatelet agents and anticoagulants) Clinical Impact: Concomitant use of citalopram and an antiplatelet or anticoagulant may potentiate the risk of bleeding. Intervention: Inform patients of the increased risk of bleeding associated with the concomitant use of Citalopram Capsules and antiplatelet agents and anticoagulants. For patients taking warfarin, carefully monitor the international normalized ratio [see Warnings and Precautions ( 5.4 )].
