What are the differences between Doxepin and Amoxapine for depression treatment?

Introduction to Tricyclic Antidepressants

Tricyclic antidepressants (TCAs) are among the oldest classes of medications for depression and anxiety. They work by blocking reuptake of neurotransmitters such as serotonin, norepinephrine, and in the case of Amoxapine, dopamine, to improve mood.

Uses of Doxepin and Amoxapine

Major Depressive Disorder

Both medications are prescribed to treat major depressive disorder. Doxepin is also used for anxiety and off-label for insomnia and dermatological itching, while Amoxapine is effective for depression with psychotic features.

Additional Indications

Doxepin treats eczema-related itching and off-label chronic pain. Amoxapine may also be used for neuropathic pain and insomnia. Both medications are prescribed when first-line treatments are ineffective.

Mechanism of Action

Doxepin blocks serotonin and norepinephrine reuptake, boosting these neurotransmitters. Amoxapine shares this but additionally blocks dopamine, making it suitable for depression with psychosis.
