ESCITALOPRAM

Escitalopram Tablets, USP are an orally administered selective serotonin reuptake inhibitor (SSRI). Escitalopram is the pure S-enantiomer (single isomer) of the racemic bicyclic phthalane derivative citalopram. Escitalopram oxalate is designated S-(+)-1-[3-(dimethyl-amino)propyl]-1-(p-fluorophenyl)-5-phthalancarbonitrile oxalate with the following structural formula: The molecular formula is C 20 H 21 FN 2 O • C 2 H 2 O 4 and the molecular weight is 414.40. Escitalopram oxalate, USP occurs as a fine, white to off-white powder and is freely soluble in methanol and dimethyl sulfoxide (DMSO), soluble in isotonic saline solution, sparingly soluble in water and ethanol, slightly soluble in ethyl acetate, and insoluble in heptane. Escitalopram oxalate is available as tablets. Escitalopram Tablets, USP are film-coated, round tablets containing escitalopram oxalate in strengths equivalent to 5 mg, 10 mg, and 20 mg escitalopram base. The 10 and 20 mg tablets are scored. The tablets also contain the following inactive ingredients: butylated hydroxyanisole, croscarmellose sodium, lactose monohydrate, magnesium stearate and microcrystalline cellulose. The film coating contains hydroxypropyl cellulose, hypromellose, polyethylene glycol, and titanium dioxide. Image

A fixed-dose trial of escitalopram tablets demonstrated the effectiveness of both 10 mg and 20 mg of escitalopram tablets, but failed to demonstrate a greater benefit of 20 mg over 10 mg [ see Clinical Studies ( 14.1 ) ]. Depending on clinical response and tolerability, dosage may be increased to the maximum recommended dosage of 20 mg once daily at an interval of no less than 1 week. Pediatric Patients 12 years of age and older The recommended dosage of escitalopram tablet in pediatric patients 12 years of age and older is 10 mg once daily. Depending on clinical response and tolerability, dosage may be increased to the maximum recommended dosage of 20 mg once daily at an interval of no less than 3 weeks. 2.2 Generalized Anxiety Disorder Adults The recommended starting dose of escitalopram tablets is 10 mg once daily. If the dose is increased to 20 mg, this should occur after a minimum of one week. Depending on clinical response and tolerability, dosage may be increased to the maximum recommended dosage of 20 mg once daily at an interval of no less than 1 week. Additional pediatric use information is approved for AbbVie Inc.'s LEXAPRO (escitalopram) tablets. However, due to AbbVie Inc.'s marketing exclusivity rights, this drug product is not labeled with that information. 2.3 Administration Information Administer Escitalopram tablets orally once daily, in the morning or evening, with or without food. 2.4 Screen for Bipolar Disorder Prior to Starting Escitalopram Tablets Prior to initiating treatment with escitalopram tablets or another antidepressant, screen patients for a personal family history of bipolar disorder, mania, or hypomania [ see Warnings and Precautions ( 5.5 ) ]. 2.5 Recommended Dosage for Specific Populations The recommended dosage for most elderly patients and patients with hepatic impairment is 10 mg once daily [see Use in Specific Populations ( 8.5 , 8.6 )]. The recommended dosage for Escitalopram tablets in adults with a creatinine clearance less than 20 mL/minute has not been determined. No dosage adjustment is necessary for patients with mild or moderate renal impairment [see Use in Specific Populations ( 8.7 )]. 2.6 Discontinuation of Treatment with Escitalopram Tablets Symptoms associated with discontinuation of escitalopram tablets and other SSRIs and SNRIs have been reported [see Warnings and Precautions ( 5.3 )]. Patients should be monitored for these symptoms when discontinuing treatment. A gradual reduction in the dose rather than abrupt cessation is recommended whenever possible. If intolerable symptoms occur following a decrease in the dose or upon discontinuation of treatment, then resuming the previously prescribed dose may be considered. Subsequently, the physician may continue decreasing the dose but at a more gradual rate. 2.7 Switching a Patient to or from a Monoamine Oxidase Inhibitor (MAOI) Antidepressant At least 14 days should elapse between discontinuation of an MAOI intended to treat psychiatric disorders and initiation of therapy with escitalopram tablets. Conversely, at least 14 days should be allowed after stopping escitalopram tablets before starting an MAOI intended to treat psychiatric disorders [ see Contraindications ( 4 ) ].

Escitalopram tablets is contraindicated in patients: taking MAOIs with Escitalopram tablets or within 14 days of stopping treatment with Escitalopram tablets because of an increased risk of serotonin syndrome. The use of Escitalopram tablets within 14 days of stopping an MAOI intended to treat psychiatric disorders is also contraindicated [see Dosage and Administration ( 2.7 ) and Warnings and Precautions ( 5.2 )]. Starting Escitalopram tablets in a patient who is being treated with MAOIs such as linezolid or intravenous methylene blue is also contraindicated because of an increased risk of serotonin syndrome [see Dosage and Administration ( 2.6 ) and Warnings and Precautions ( 5.2 )]. taking pimozide [see Drug Interactions ( 7 )]. with a hypersensitivity to escitalopram or citalopram or any of the inactive ingredients in Escitalopram tablets. Do not use MAOIs intended to treat psychiatric disorders with Escitalopram tablets or within 14 days of stopping treatment with Escitalopram tablets. Do not use Escitalopram tablets within 14 days of stopping an MAOI intended to treat psychiatric disorders. In addition, do not start Escitalopram tablets in a patient who is being treated with linezolid or intravenous methylene blue ( 4 ) Known hypersensitivity to escitalopram or citalopram or any of the inactive ingredients ( 4 )

The following adverse reactions are discussed in greater detail in other sections of the labeling: Suicidal thoughts and behaviors in adolescents and young adults [see Warnings and Precautions ( 5.1 )] Serotonin syndrome [see Warnings and Precautions ( 5.2 )] Discontinuation syndrome [see Warnings and Precautions ( 5.3 )] Seizures [see Warnings and Precautions ( 5.4 )] Activation of mania or hypomania [see Warnings and Precautions ( 5.5 )] Hyponatremia [see Warnings and Precautions ( 5.6 )] Increased Risk of Bleeding [see Warnings and Precautions ( 5.7 )] Interference with Cognitive and Motor Performance [see Warnings and Precautions ( 5.8 )] Angle-closure glaucoma [see Warnings and Precautions ( 5.9 )] Use in Patients with Concomitant Illness [see Warnings and Precautions ( 5.10 )] Sexual Dysfunction [see Warnings and Precautions ( 5.11 )] Most commonly observed adverse reactions (incidence ≥ 5% and at least twice the incidence of placebo patients) are: insomnia, ejaculation disorder (primarily ejaculatory delay), nausea, sweating increased, fatigue and somnolence, decreased libido, and anorgasmia ( 6.1 ).

Clinical Trial Data Sources Adults Adverse reactions information for escitalopram was collected from 715 patients with major depressive disorder who were exposed to escitalopram and from 592 patients who were exposed to placebo in double-blind, placebo-controlled trials. An additional 284 patients with major depressive disorder were newly exposed to escitalopram in open-label trials. The adverse event information for escitalopram in patients with GAD was collected from 429 patients exposed to escitalopram and from 427 patients exposed to placebo in double-blind, placebo-controlled trials. Adverse reactions during exposure were obtained primarily by general inquiry and recorded by clinical investigators using terminology of their own choosing. Consequently, it is not possible to provide a meaningful estimate of the proportion of individuals experiencing adverse reactions without first grouping similar types of reactions into a smaller number of standardized event categories. In the tables and tabulations that follow, standard World Health Organization (WHO) terminology has been used to classify reported adverse reactions. The stated frequencies of adverse reactions represent the proportion of individuals who experienced, at least once, a treatment emergent adverse event of the type listed. An event was considered treatment-emergent if it occurred for the first time or worsened while receiving therapy following baseline evaluation. Pediatric Patients Adverse reaction information for pediatric patients was collected in double-blind placebo-controlled studies in 576 pediatric patients 6 to 17 years of age, (286 escitalopram tablets, 290 placebo) with major depressive disorder and in 273 pediatric patients 7 to 17 years of age (137 escitalopram tablets, 136 placebo) with generalized anxiety disorder. The safety and effectiveness of escitalopram tablets have not been established in pediatric patients less than 12 years of age with MDD or less than 7 years of age with GAD. Adverse Reactions Associated with Discontinuation of Treatment Major Depressive Disorder Adults Among the 715 depressed patients who received escitalopram in placebo-controlled trials, 6% discontinued treatment due to an adverse event, as compared to 2% of 592 patients receiving placebo. In two fixed-dose studies, the rate of discontinuation for adverse reactions in patients receiving 10 mg/day escitalopram was not significantly different from the rate of discontinuation for adverse reactions in patients receiving placebo. The rate of discontinuation for adverse reactions in patients assigned to a fixed dose of 20 mg/day escitalopram was 10%, which was significantly different from the rate of discontinuation for adverse reactions in patients receiving 10 mg/day escitalopram (4%) and placebo (3%). Adverse reactions that were associated with the discontinuation of at least 1% of patients treated with escitalopram, and for which the rate was at least twice that of placebo, were nausea (2%) and ejaculation disorder (2% of male patients). Pediatric Patients Adverse reactions in pediatric patients 6 to 17 years of age were associated with discontinuation of 3.5% of 286 patients receiving escitalopram tablets and 1% of 290 patients receiving placebo. The most common adverse reaction (incidence at least 1% for escitalopram tablets and greater than placebo) associated with discontinuation was insomnia (1% escitalopram tablets, 0% placebo). The safety and effectiveness of escitalopram tablets have not been established in pediatric patients less than 12 years of age with MDD. Generalized Anxiety Disorder Adults Among the 429 GAD patients who received escitalopram 10 to 20 mg/day in placebo-controlled trials, 8% discontinued treatment due to an adverse event, as compared to 4% of 427 patients receiving placebo. Adverse reactions that were associated with the discontinuation of at least 1% of patients treated with escitalopram, and for which the rate was at least twice the placebo rate, were nausea (2%), insomnia (1%), and fatigue (1%). Incidence of Adverse Reactions in Placebo-Controlled Clinical Trials Major Depressive Disorder Adults The most commonly observed adverse reactions in escitalopram patients (incidence of approximately 5% or greater and approximately twice the incidence in placebo patients) were insomnia, ejaculation disorder (primarily ejaculatory delay), nausea, sweating increased, fatigue, and somnolence. Table 2 enumerates the incidence, rounded to the nearest percent, of treatment-emergent adverse reactions that occurred among 715 depressed patients who received escitalopram at doses ranging from 10 to 20 mg/day in placebo-controlled trials. Reactions included are those occurring in 2% or more of patients treated with escitalopram and for which the incidence in patients treated with escitalopram was greater than the incidence in placebo-treated patients. 1 Primarily ejaculatory delay. 2 Denominator used was for males only (N=225 escitalopram; N=188 placebo). 3 Denominator used was for females only (N=490 escitalopram; N=404 placebo).

However, the following adverse reactions (excluding those which appear in Table 2 and those for which the coded terms were uninformative or misleading) were reported at an incidence of at least 2% for escitalopram tablets and greater than placebo: back pain, urinary tract infection, vomiting, and nasal congestion. The safety and effectiveness of escitalopram tablets have not been established in pediatric patients less than 12 years of age with MDD. Generalized Anxiety Disorder Adults The most commonly observed adverse reactions in escitalopram patients (incidence of approximately 5% or greater and approximately twice the incidence in placebo patients) were nausea, ejaculation disorder (primarily ejaculatory delay), insomnia, fatigue, decreased libido, and anorgasmia. Table 3 enumerates the incidence, rounded to the nearest percent of treatment-emergent adverse reactions that occurred among 429 GAD patients who received escitalopram 10 to 20 mg/day in placebo-controlled trials. Reactions included are those occurring in 2% or more of patients treated with escitalopram and for which the incidence in patients treated with escitalopram was greater than the incidence in placebo-treated patients. 1 Primarily ejaculatory delay. 2 Denominator used was for males only (N=182 escitalopram; N=195 placebo). 3 Denominator used was for females only (N=247 escitalopram; N=232 placebo).

The overall incidence rates of adverse reactions in 10 mg escitalopram-treated patients (66%) was similar to that of the placebo-treated patients (61%), while the incidence rate in 20 mg/day escitalopram-treated patients was greater (86%). Table 4 shows common adverse reactions that occurred in the 20 mg/day escitalopram group with an incidence that was approximately twice that of the 10 mg/day escitalopram group and approximately twice that of the placebo group. TABLE 4 Incidence of Common Adverse Reactions in Patients with Major Depressive Disorder Adverse Reaction Placebo (N=311) 10 mg/day Escitalopram (N=310) 20 mg/day Escitalopram (N=125) Insomnia 4% 7% 14% Diarrhea 5% 6% 14% Dry Mouth 3% 4% 9% Somnolence 1% 4% 9% Dizziness 2% 4% 7% Sweating Increased <1% 3% 8% Constipation 1% 3% 6% Fatigue 2% 2% 6% Indigestion 1% 2% 6% 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 pharmacologic treatment. In particular, some evidence suggests that SSRIs can cause such untoward sexual experiences. Reliable estimates of the incidence and severity of untoward experiences involving sexual desire, performance, and satisfaction are difficult to obtain, however, in part because patients and physicians 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 5 Incidence of Sexual Side Effects in Placebo-Controlled Clinical Trials Adverse Event Escitalopram Placebo In Males Only (N=407) (N=383) Ejaculation Disorder (primarily ejaculatory delay) 12% 1% Libido Decreased 6% 2% Impotence 2% <1% In Females Only (N=737) (N=636) Libido Decreased 3% 1% Anorgasmia 3% <1% There are no adequately designed studies examining sexual dysfunction with escitalopram treatment. Priapism has been reported with all SSRIs. While it is difficult to know the precise risk of sexual dysfunction associated with the use of SSRIs, physicians should routinely inquire about such possible side effects. Vital Sign Changes Escitalopram and placebo groups were compared with respect to (1) mean change from baseline in vital signs (pulse, systolic blood pressure, and diastolic blood pressure) and (2) the incidence of patients meeting criteria for potentially clinically significant changes from baseline in these variables. These analyses did not reveal any clinically important changes in vital signs associated with escitalopram treatment. In addition, a comparison of supine and standing vital sign measures in subjects receiving escitalopram indicated that escitalopram treatment is not associated with orthostatic changes. Weight Changes Patients treated with escitalopram in controlled trials did not differ from placebo-treated patients with regard to clinically important change in body weight. Laboratory Changes Escitalopram and placebo groups were compared with respect to (1) mean change from baseline in various serum chemistry, hematology, and urinalysis variables, and (2) the incidence of patients meeting criteria for potentially clinically significant changes from baseline in these variables. These analyses revealed no clinically important changes in laboratory test parameters associated with escitalopram treatment. ECG Changes Electrocardiograms from escitalopram (N=625) and placebo (N=527) 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). None of the patients in the escitalopram group had a QTcF interval >500 msec or a prolongation >60 msec compared to 0.2% of patients in the placebo group. The incidence of tachycardic outliers was 0.2% in the escitalopram and the placebo group. The incidence of bradycardic outliers was 0.5% in the escitalopram group and 0.2% in the placebo group. QTcF interval was evaluated in a randomized, placebo and active (moxifloxacin 400 mg) controlled cross-over, escalating multiple dose study in 113 healthy subjects. The maximum mean (95% upper confidence bound) difference from placebo arm were 4.5 (6.4) and 10.7 (12.7) msec for 10 mg and supratherapeutic 30 mg escitalopram given once daily, respectively. Based on the established exposure-response relationship, the predicted QTcF change from placebo arm (95% confidence interval) under the Cmax for the dose of 20 mg is 6.6 (7.9) msec. Escitalopram 30 mg given once daily resulted in mean Cmax of 1.7-fold higher than the mean Cmax for the maximum recommended therapeutic dose at steady state (20 mg). The exposure under supratherapeutic 30 mg dose is similar to the steady state concentrations expected in CYP2C19 poor metabolizers following a therapeutic dose of 20 mg.

Table 6 presents clinically important drug interactions with Escitalopram tablets. TABLE 6 Clinically Important Drug Interactions with Escitalopram tablets Monoamine Oxidase Inhibitors (MAOIs) Clinical Impact: Concomitant use of SSRIs, including Escitalopram tablets, and MAOIs increases the risk of serotonin syndrome. Intervention: Escitalopram tablets is contraindicated in patients taking MAOIs, including MAOIs such as linezolid or intravenous methylene blue [see Dosage and Administration ( 2.7 ), Contraindications ( 4 ), and Warnings and Precautions ( 5.2 )]. Pimozide Clinical Impact: Concomitant use of racemic 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 racemic citalopram alone [see Clinical Pharmacology ( 12.3 )]. Intervention: Escitalopram tablets is contraindicated in patients taking pimozide [see Contraindications ( 4 )]. Serotonergic Drugs Clinical Impact: Concomitant use of Escitalopram tablets and other serotonergic drugs (including other SSRIs, SNRIs, triptans, tricyclic antidepressants, opoids, lithium, buspirone, amphetamines, tryptophan, and St. John's Wot) increases the risk of serotonin syndrome. Intervention: Monitor patients for signs and symptoms of serotonin syndrome, particularly during Escitalopram tablets initiation and dosage increases. If serotonin syndrome occurs, consider discontinuation of Escitalopram tablets and/or concomitant serotonergic drugs [see Warning and Precautions ( 5.2 )]. Drugs That Interfere With Hemostasis (NSAIDs, Aspirin, Warfarin, etc.) Clinical Impact: Concomitant use of Escitalopram tablets 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 Escitalopram tablets and antiplatelet agents and anticoagulants. For patients taking warfarin, carefully monitor the international normalized ratio [see Warning and Precautions ( 5.7 )]. Sumatriptan Clinical Impact: There have been postmarketing reports describing patients with weakness, hyperreflexia, and incoordination following the use of an SSRI and sumatriptan. Intervention: If concomitant treatment with sumatriptan and an SSRI is clinically warranted, appropriate observation of the patient is advised [see Warning and Precautions ( 5.2 )]. Carbamazepine Clinical Impact: Combined administration of racemic citalopram (40 mg/day for 14 days) and carbamazepine (titrated to 400 mg/day for 35 days) did not significantly affect the pharmacokinetics of carbamazepine, a CYP3A4 substrate. Intervention: Although trough citalopram plasma levels were unaffected, given the enzyme-inducing properties of carbamazepine, the possibility that carbamazepine might increase the clearance of escitalopram should be considered if the two drugs are coadministered. Drugs Metabolized by CYP2D6 Clinical Impact: Coadministration of escitalopram (20 mg/day for 21 days) with the tricyclic antidepressant desipramine (single dose of 50 mg), a substrate for CYP2D6, resulted in a 40% increase in C max and a 100% increase in AUC of desipramine. Intervention: The clinical significance of this finding is unknown. Exercise caution during coadministration of escitalopram and drugs metabolized by CYP2D6. Concomitant use with SSRIs, SNRIs or Tryptophan is not recommended ( 7 ). Use caution when concomitant use with drugs that affect Hemostasis (NSAIDs, Aspirin, Warfarin) ( 7 ).
