What is the mechanism of action of this treatment?

Common treatments for depression, such as SSRIs, SNRIs, TCAs, and atypical antipsychotics, primarily work by modulating neurotransmitter levels in the brain, particularly serotonin and norepinephrine. This modulation helps to improve mood and emotional stability, which is essential for alleviating depressive symptoms. Understanding these mechanisms is important for patients as it provides insight into how these medications can help manage their condition and what side effects might be expected. This knowledge also aids clinicians in tailoring treatments to individual needs, enhancing the likelihood of successful outcomes.

What side effects are associated with this type of intervention?

Common treatments for depression, including SSRIs (e.g., fluoxetine, escitalopram), SNRIs (e.g., venlafaxine, duloxetine), tricyclic antidepressants (e.g., amitriptyline), and atypical antidepressants (e.g., bupropion, mirtazapine), have a range of side effects. SSRIs and SNRIs often cause nausea, headache, and insomnia. Tricyclic antidepressants can lead to dry mouth, constipation, urinary retention, and orthostatic hypotension. Atypical antidepressants may cause weight gain, sedation, or agitation.

What prior FDA approvals exist?

The FDA has approved several classes of drugs for the treatment of depression, including selective serotonin reuptake inhibitors (SSRIs) like fluoxetine and sertraline, serotonin-norepinephrine reuptake inhibitors (SNRIs) such as venlafaxine and duloxetine, and tricyclic antidepressants like amitriptyline and imipramine. Atypical antidepressants, including bupropion and mirtazapine, have also been approved. These treatments vary in their mechanisms of action and efficacy, providing multiple options for managing depression.
