What is Brisdelle (Paroxetine)?

Major Depressive Disorder Paroxetine tablets are indicated for the treatment of major depressive disorder. The efficacy of paroxetine in the treatment of a major depressive episode was established in 6-week controlled trials of outpatients whose diagnoses corresponded most closely to the DSM-III category of major depressive disorder. A major depressive episode implies a prominent and relatively persistent depressed or dysphoric mood that usually interferes with daily functioning ; it should include at least 4 of the following 8 symptoms: Change in appetite, change in sleep, psychomotor agitation or retardation, loss of interest in usual activities or decrease in sexual drive, increased fatigue, feelings of guilt or worthlessness, slowed thinking or impaired concentration, and a suicide attempt or suicidal ideation. The effects of paroxetine in hospitalized depressed patients have not been adequately studied. The efficacy of paroxetine in maintaining a response in major depressive disorder for up to 1 year was demonstrated in a placebo-controlled trial. Nevertheless, the physician who elects to use paroxetine for extended periods should periodically re-evaluate the long-term usefulness of the drug for the individual patient. Obsessive Compulsive Disorder Paroxetine tablets are indicated for the treatment of obsessions and compulsions in patients with obsessive compulsive disorder as defined in the DSM-IV. The obsessions or compulsions cause marked distress, are time-consuming, or significantly interfere with social or occupational functioning. The efficacy of paroxetine was established in two 12-week trials with obsessive compulsive outpatients whose diagnoses corresponded most closely to the DSM-IIIR category of obsessive compulsive disorder. Obsessive compulsive disorder is characterized by recurrent and persistent ideas, thoughts, impulses, or images that are ego-dystonic and/or repetitive, purposeful, and intentional behaviors that are recognized by the person as excessive or unreasonable. Long-term maintenance of efficacy was demonstrated in a 6-month relapse prevention trial. In this trial, patients assigned to paroxetine showed a lower relapse rate compared to patients on placebo. Nevertheless, the physician who elects to use paroxetine for extended periods should periodically re-evaluate the long-term usefulness of the drug for the individual patient. Panic Disorder Paroxetine tablets are indicated for the treatment of panic disorder, with or without agoraphobia, as defined in DSM-IV. Panic disorder is characterized by the occurrence of unexpected panic attacks and associated concern about having additional attacks, worry about the implications or consequences of the attacks, and/or a significant change in behavior related to the attacks. The efficacy of paroxetine was established in three 10- to 12-week trials in panic disorder patients whose diagnoses corresponded to the DSM-IIIR category of panic disorder. Panic disorder is characterized by recurrent unexpected panic attacks, i.e., a discrete period of intense fear or discomfort in which 4 of the following symptoms develop abruptly and reach a peak within 10 minutes: palpitations, pounding heart, or accelerated heart rate; sweating; trembling or shaking; sensations of shortness of breath or smothering; feeling of choking; chest pain or discomfort; nausea or abdominal distress; feeling dizzy, unsteady, lightheaded, or faint; derealization or depersonalization ; fear of losing control; fear of dying; paresthesias ; chills or hot flushes. Long-term maintenance of efficacy was demonstrated in a 3-month relapse prevention trial. In this trial, patients with panic disorder assigned to paroxetine demonstrated a lower relapse rate compared to patients on placebo. Nevertheless, the physician who prescribes paroxetine for extended periods should periodically re-evaluate the long-term usefulness of the drug for the individual patient. Social Anxiety Disorder Paroxetine tablets are indicated for the treatment of social anxiety disorder, also known as social phobia, as defined in DSM-IV (30.

Brand Information

    WARNING: SUICIDAL THOUGHTS AND BEHAVIORS
    Selective serotonin reuptake inhibitors (SSRIs) increased the risk of suicidal thoughts and behavior in pediatric and young adult patients in short-term trials for the treatment of major depressive disorder and other psychiatric disorders. Because BRISDELLE is an SSRI, closely monitor BRISDELLE-treated patients closely for emergence of suicidal thoughts and behaviors
    1INDICATIONS AND USAGE
    BRISDELLE is indicated for the treatment of moderate to severe vasomotor symptoms (VMS) associated with menopause.
    Limitations of Use:
    BRISDELLE is not indicated for the treatment of any psychiatric condition. BRISDELLE has a lower recommended paroxetine dosage than that used to treat major depressive disorder, obsessive compulsive disorder, panic disorder, generalized anxiety disorder, social anxiety disorder, and post-traumatic stress disorder. The safety and effectiveness of the lower BRISDELLE dosage has not been established for any psychiatric condition. Patients who require paroxetine for treatment of a psychiatric condition should discontinue BRISDELLE and initiate a paroxetine-containing product that is indicated for such use.
    2DOSAGE FORMS AND STRENGTHS
    BRISDELLE is available as 7.5 mg pink capsules printed with black edible ink with “BRISDELLE” and “7.5 mg” on the capsule. Each capsule contains 9.69 mg of paroxetine mesylate equivalent to 7.5 mg paroxetine base.
    3CONTRAINDICATIONS
    BRISDELLE is contraindicated in patients:
    • Taking, or within 14 days of stopping, MAOIs (including the MAOIs linezolid and intravenous methylene blue) because of an increased risk of serotonin syndrome
    • Taking thioridazine because of risk of QT prolongation
    • Taking pimozide because of risk of QT prolongation
    • With known hypersensitivity (e.g., anaphylaxis, angioedema, Stevens-Johnson syndrome) to paroxetine or to any of the inactive ingredients in BRISDELLE
    • Who are or become pregnant because menopausal VMS does not occur during pregnancy and BRISDELLE may cause fetal harm
    4ADVERSE REACTIONS
    The following serious adverse reactions are discussed elsewhere in labeling:
    • Suicidality
    • Serotonin syndrome
    • Abnormal bleeding
    • Angle-Closure Glaucoma
    • Hyponatremia
    • Bone Fracture
    • Mania/Hypomania
    • Seizure
    4.1Clinical Trials Experience
    Because clinical trials are conducted under widely varying conditions, adverse reaction rates observed in the clinical trials of a drug cannot directly be compared to rates in the clinical trials of another drug and may not reflect the rates observed in practice.
    The data described below reflect exposure to BRISDELLE in the following randomized, placebo-controlled trials for the treatment of moderate to severe VMS associated with menopause
    Serious Adverse Reactions:
    In the pooled Phase 2 and Phase 3 trials, three BRISDELLE-treated patients reported a serious adverse reaction of suicidal ideation and one BRISDELLE-treated patient reported a serious adverse reaction of suicide attempt. There were no serious adverse reactions of suicidal ideation or suicide attempt reported among the placebo-treated patients.
    Adverse Reactions Leading to Study Discontinuation:
    A total of 4.7% of females taking BRISDELLE discontinued from the clinical trials due to an adverse reaction, compared to 3.7% of females on placebo; the most frequent adverse reactions leading to discontinuation among paroxetine-treated females were: abdominal pain (0.3%), attention disturbances (0.3%), headache (0.3%), and suicidal ideation (0.3%).
    Common Adverse Reactions:
    Overall, based on investigators’ determinations about what events were likely to be drug-related, about 20% of postmenopausal females treated with BRISDELLE reported at least 1 adverse reaction in the three controlled trials. The most common adverse reactions (≥ 2% and at a higher incidence in BRISDELLE-treated females compared to placebo-treated females) reported in these trials were headache, fatigue/malaise/lethargy, and nausea/vomiting. Of these commonly reported adverse reactions, nausea occurred primarily within the first 4 weeks of BRISDELLE treatment and fatigue occurred primarily within the first week of BRISDELLE treatment, and decreased in frequency with continued therapy.
    The adverse reactions that occurred in ≥ 2% of BRISDELLE-treated patients and at a higher incidence in BRISDELLE-treated females compared to placebo-treated females are shown in Table 1 for the pooled Phase 2 and Phase 3 trials.
    Table 1: Incidence of Common Adverse Reactions in the Phase 2 and Phase 3 Trials of Postmenopausal Females with Moderate to Severe VMS
    1 ≥ 2% BRISDELLE-treated patients and at a higher incidence in BRISDELLE-treated females compared to placebo-treated females.
    Adverse Reactions After Discontinuing BRISDELLE
    Certain symptoms were seen more frequently in postmenopausal females at the time of discontinuation of BRISDELLE compared to discontinuation of placebo and have also been reported upon discontinuation of other paroxetine products, particularly after abrupt discontinuation. Adverse reactions reported after discontinuation of BRISDELLE included increased dreaming/nightmares, muscle cramps/spasms/twitching, headache, nervousness/anxiety, fatigue/tiredness, restless feeling in legs, and trouble sleeping/insomnia. While these adverse reactions were generally self-limiting, there have been reports of serious discontinuation symptoms with other paroxetine products.
    4.2Postmarketing Experience
    The following adverse reactions have been identified during post-approval use of this and other paroxetine products. Because some of these reactions are reported voluntarily from a population of uncertain size, it is not always possible to reliably estimate their frequency or establish a

    7CLINICAL STUDIES
    The effectiveness of BRISDELLE as a treatment for moderate to severe vasomotor symptoms (VMS) associated with menopause was established in two Phase 3 randomized, double-blind, placebo-controlled clinical trials in 1,174 postmenopausal females. In these trials, patients must have had a minimum of 7-8 moderate to severe VMS per day at baseline (≥ 50 per week) for 30 days prior to receiving study drug. Patients were randomized to BRISDELLE 7.5 mg orally once daily or daily placebo:
    • Trial 1 was a 12-week trial with a total of 606 postmenopausal females (average age 55 years; 65% White, 33% Black or African American, and 2% other races; 10.6% were Hispanic/Latina and 89.4% were not Hispanic/Latina; 18% surgically menopausal and 82% naturally menopausal).
    • Trial 2 was a 24-week trial with a total of 568 postmenopausal females (average age 54 years; 76% White, 22% Black or African American, and 2% other races; 6.5% were Hispanic/Latina and 93.5% were not Hispanic/Latina; 20% surgically menopausal and 81% naturally menopausal).
    The co-primary efficacy endpoints for both trials were the reduction from baseline in VMS frequency and VMS severity at Weeks 4 and 12.
    • Data from Trial 1 showed a statistically significant reduction from baseline in the frequency of moderate to severe VMS at Week 4 and Week 12 and a statistically significant reduction in the severity of moderate to severe VMS at Week 4 in the BRISDELLE group compared to the placebo group (Table 4).
    • Data from Trial 2 showed a statistically significant reduction from baseline in the frequency and severity of moderate to severe VMS at Week 4 and Week 12 in the BRISDELLE group compared to placebo group (Table 5).
    Table 4: Trial 1: Changes in the Daily Frequency and Daily Severity of VMS at Weeks 4 and 12 in Postmenopausal Females with Moderate to Severe VMS (MITT Population)
    MITT population: all consented and randomized patients with valid baseline daily hot flash diary data who had taken at least 1 dose of study drug and had at least 1 day of on-treatment daily hot flash diary data.
    Table 5: Trial 2: Changes in the Daily Frequency and Daily Severity of VMS at Weeks 4 and 12 in Postmenopausal Females with Moderate to Severe VMS (MITT Population)
    MITT population: all consented and randomized patients with valid baseline daily hot flash diary data who had taken at least 1 dose of study drug and had at least 1 day of on-treatment daily hot flash diary data.
    Persistence of benefit at 24 weeks in Trial 2 was evaluated with a responder analysis where responders were defined as those patients who achieved ≥ 50% reduction from baseline in the frequency of moderate to severe VMS at Week 24. The proportion of patients who achieved a ≥ 50% reduction in the frequency of moderate to severe VMS from baseline to Week 24 was 48% in the BRISDELLE group and 36% in the placebo group at Week 24.
