Escitalopram

The safety and effectiveness of escitalopram 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 tablets, and for which the rate was at least twice that of placebo, were nausea (2%) and ejaculation disorder (2% of male patients).

5% of 286 patients receiving escitalopram and 1% of 290 patients receiving placebo. The most common adverse reaction (incidence at least 1% for escitalopram and greater than placebo) associated with discontinuation was insomnia (1% escitalopram, 0% placebo).

The safety and effectiveness of escitalopram 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 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 and greater than placebo: back pain, urinary tract infection, vomiting, and nasal congestion.

The safety and effectiveness of escitalopram 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 10 mg/day 20 mg/day (N=311) Escitalopram Escitalopram (N=310) (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).

2% of patients in the placebo group. 2% in the escitalopram and the placebo group. 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.

7) msec for 10 mg and supratherapeutic 30 mg escitalopram given once daily, respectively. 9) msec. 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.

The risk is increased with concomitant use of other serotonergic drugs (including triptans, tricyclic antidepressants, fentanyl, meperidine, methadone, lithium, tramadol, tryptophan, buspirone, amphetamines, and St. , MAOIs [see Contraindications ( 4 ) and Drug Interactions ( 7 )] .

, nausea, vomiting, diarrhea). The concomitant use of escitalopram with MAOIs is contraindicated. In addition, do not initiate Escitalopram in a patient who is being treated with MAOIs such as linezolid or intravenous methylene blue.

No reports involved the administration of methylene blue by other routes (such as oral tablets or local tissue injection). 7 )] . Monitor all patients taking escitalopram tablets for the emergence of serotonin syndrome. Discontinue treatment with escitalopram tablets and any concomitant serotonergic agents immediately if the above symptoms occur, and initiate supportive symptomatic treatment.

If concomitant use of escitalopram with other serotonergic drugs is clinically warranted, inform patients of the increased risk for serotonin syndrome and monitor for symptoms. , paresthesias such as electric shock sensations), anxiety, confusion, headache, lethargy, emotional lability, insomnia, and hypomania.

While these events are generally self-limiting, there have been reports of serious discontinuation symptoms. Monitor for these symptoms when discontinuing treatment with escitalopram. 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. 6 )] . 4 Seizures Although anticonvulsant effects of racemic citalopram have been observed in animal studies, escitalopram has not been systematically evaluated in patients with a seizure disorder.

These patients were excluded from clinical studies during the product's premarketing testing. In clinical trials of escitalopram, cases of convulsion have been reported in association with escitalopram treatment. Like other drugs effective in the treatment of major depressive disorder, escitalopram tablets should be introduced with care in patients with a history of seizure disorder.

5 Activation of Mania or Hypomania In patients with bipolar disorder, treating a depressive episode with escitalopram or another antidepressant may precipitate a mixed/manic episode. 1%) of 715 patients treated with escitalopram and in none of the 592 patients treated with placebo.

One additional case of hypomania has been reported in association with escitalopram treatment. Activation of mania/hypomania has also been reported in a small proportion of patients with major affective disorders treated with racemic citalopram and other marketed drugs effective in the treatment of major depressive disorder.

4 )] . 6 Hyponatremia Hyponatremia may occur as a result of treatment with SSRIs, including escitalopram. In many cases, this hyponatremia appears to be the result of the syndrome of inappropriate antidiuretic hormone secretion (SIADH), and was reversible when escitalopram was discontinued.

Cases with serum sodium lower than 110 mmol/L have been reported. Elderly patients may be at greater risk of developing hyponatremia with SSRIs and SNRIs. 5 )] . Consider discontinuation of escitalopram in patients with symptomatic hyponatremia and appropriate medical intervention should be instituted.

Signs and symptoms of hyponatremia include headache, difficulty concentrating, memory impairment, confusion, weakness, and unsteadiness, which may lead to falls. Signs and symptoms associated with more severe and/or acute cases have included hallucination, syncope, seizure, coma, respiratory arrest, and death.

7 Increased Risk of Bleeding Drugs that interfere with serotonin reuptake inhibition, including escitalopram, increase the risk of bleeding events. Concomitant use of aspirin, nonsteroidal anti-inflammatory drugs (NSAIDs), other antiplatelet drugs, warfarin, and other anticoagulants may add to the risk.

Case reports and epidemiological studies (case-control and cohort design) have demonstrated an association between use of drugs that interfere with serotonin reuptake and the occurrence of gastrointestinal bleeding. 1 )] . Bleeding events related to drugs that interfere with serotonin reuptake have ranged from ecchymoses, hematomas, epistaxis, and petechiae to life-threatening hemorrhages.

Inform patients about the increased risk of bleeding associated with the concomitant use of escitalopram and antiplatelet agents or anticoagulants. For patients taking warfarin, carefully monitor the international normalized ratio [see Drug Interactions ( 7 )] .

8 Interference with Cognitive and Motor Performance In a study in normal volunteers, escitalopram 10 mg daily did not produce impairment of intellectual function or psychomotor performance. Because any psychoactive drug may impair judgment, thinking, or motor skills, however, patients should be cautioned about operating hazardous machinery, including automobiles, until they are reasonably certain that escitalopram tablets therapy does not affect their ability to engage in such activities.

9 Angle Closure Glaucoma The pupillary dilation that occurs following use of many antidepressant drugs, including escitalopram may trigger an angle closure attack in a patient with anatomically narrow angles who does not have a patent iridectomy.

10 Use in Patients with Concomitant Illness Clinical experience with escitalopram in patients with certain concomitant systemic illnesses is limited. Caution is advisable in using escitalopram tablets in patients with diseases or conditions that produce altered metabolism or hemodynamic responses.

Escitalopram has not been systematically evaluated in patients with a recent history of myocardial infarction or unstable heart disease. Patients with these diagnoses were generally excluded from clinical studies during the product's premarketing testing.

In subjects with hepatic impairment, clearance of racemic citalopram was decreased and plasma concentrations were increased. 6)] . Because escitalopram is extensively metabolized, excretion of unchanged drug in urine is a minor route of elimination.

7)] . 1 )] . In male patients, SSRI use may result in ejaculatory delay or failure, decreased libido, and erectile dysfunction. In female patients, SSRI use may result in decreased libido and delayed or absent orgasm. It is important for prescribers to inquire about sexual function prior to initiation of escitalopram and to inquire specifically about changes in sexual function during treatment, because sexual function may not be spontaneously reported.

When evaluating changes in sexual function, obtaining a detailed history (including timing of symptom onset) is important because sexual symptoms may have other causes, including the underlying psychiatric disorder. Discuss potential management strategies to support patients in making informed decisions about treatment.
