What is the first-line medication for panic disorder and depression in an adult male?

From the Guidelines

For panic disorder and depression in an adult male, selective serotonin reuptake inhibitors (SSRIs) are the first-line medication treatment. Specifically, sertraline (starting at 25-50 mg daily, gradually increasing to 50-200 mg daily), escitalopram (starting at 5-10 mg daily, increasing to 10-20 mg daily), or fluoxetine (starting at 10-20 mg daily, increasing to 20-80 mg daily) are good initial choices, as suggested by the Japanese Society of Anxiety and Related Disorders/Japanese Society of Neuropsychopharmacology 1.

Key Considerations

• Treatment should continue for at least 6-12 months after symptom resolution for depression, and often longer for panic disorder, as recommended by the American College of Physicians 1.
• These medications work by increasing serotonin levels in the brain, which helps regulate mood and anxiety.
• Side effects may include initial increased anxiety, nausea, sexual dysfunction, and insomnia, but these often improve within 2-4 weeks.
• Patients should be aware that full therapeutic effect may take 4-6 weeks, and medication should not be stopped abruptly.
• Regular follow-up is important to monitor response and adjust dosage as needed.
• Cognitive behavioral therapy is also highly recommended as an adjunct to medication for both conditions, as the combination typically produces better outcomes than either treatment alone.

Additional Recommendations

• The American College of Physicians recommends that clinicians assess patient status, therapeutic response, and adverse effects of antidepressant therapy on a regular basis beginning within 1 to 2 weeks of initiation of therapy 1.
• Clinicians should modify treatment if the patient does not have an adequate response to pharmacotherapy within 6 to 8 weeks of the initiation of therapy for major depressive disorder 1.

From the FDA Drug Label

The effectiveness of sertraline in the treatment of panic disorder was demonstrated in three double-blind, placebo-controlled studies (Studies 1-3) of adult outpatients who had a primary diagnosis of panic disorder (DSM-III-R), with or without agoraphobia.

The effectiveness of sertraline for the treatment of OCD was also demonstrated in a 12-week, multicenter, placebo-controlled, parallel group study in a pediatric outpatient population (children and adolescents, ages 6 to 17)

Patients receiving sertraline experienced a mean reduction of approximately 7 points on the YBOCS total score which was significantly greater than the mean reduction of approximately 4 points in placebo-treated patients.

In a longer-term study, patients meeting DSM-III-R criteria for OCD who had responded during a 52-week single-blind trial on sertraline 50 to 200 mg/day (n=224) were randomized to continuation of sertraline or to substitution of placebo for up to 28 weeks of observation for discontinuation due to relapse or insufficient clinical response

Patients receiving continued sertraline treatment experienced a significantly lower rate of discontinuation due to relapse or insufficient clinical response over the subsequent 28 weeks compared to those receiving placebo

The difference between sertraline and placebo in reduction from baseline in the number of full panic attacks was approximately 2 panic attacks per week in both studies

Sertraline was initiated at 25 mg/day for the first week, and then patients were dosed in a range of 50 to 200 mg/day on the basis of clinical response and toleration.

First line medication for panic disorder and depression in adult male:

• Sertraline is a potential first-line medication for the treatment of panic disorder.
• The recommended initial dose is 25 mg/day for the first week, and then the dose can be increased to a range of 50 to 200 mg/day based on clinical response and toleration.
• Sertraline has been shown to be effective in reducing the frequency of panic attacks and improving symptoms of depression in adult patients, including males 2.

From the Research

First-Line Medication for Panic Disorder and Depression in Adult Males

• The first-line medications for panic disorder include selective serotonin reuptake inhibitors (SSRIs), serotonin-norepinephrine reuptake inhibitors (SNRIs), and benzodiazepines 3, 4, 5.
• SSRIs such as fluoxetine, paroxetine, and sertraline have been shown to be effective in treating panic disorder and depression 3, 6, 7.
• SNRIs like venlafaxine have also been found to be effective in treating panic disorder and depression 3, 4, 7.
• Benzodiazepines such as alprazolam and clonazepam can be used as first-line treatments for panic disorder, but their use is often limited due to the risk of dependence and withdrawal 3, 4.

Efficacy of Different Medications

• A network meta-analysis found that diazepam, alprazolam, and clonazepam were the most effective medications for panic disorder, followed by paroxetine, venlafaxine, and fluoxetine 3.
• Another study found that escitalopram, venlafaxine, and benzodiazepines had greater efficacy and acceptability than placebo for the treatment of panic disorder 4.
• A review of treatment options for panic disorder found that SSRIs and benzodiazepines are standard first-line pharmacologic treatments, and that other antidepressants such as SNRIs and tricyclic antidepressants can be considered as alternatives 5.

Acceptability and Tolerability of Medications

• Benzodiazepines were found to be associated with a lower dropout rate compared to placebo and were ranked as the most tolerated of all the medications examined 3.
• A study found that escitalopram and venlafaxine had relatively good acceptability, but that the acceptability of paroxetine and sertraline were significantly less tolerated than benzodiazepines 4.
• A review of treatment options for panic disorder found that the quality of the studies comparing antidepressants with placebo was moderate, while the quality of the studies comparing benzodiazepines with placebo and antidepressants was low 5.
