Escitalopram

Overview

Basic Info

SummaryEscitalopram is a selective serotonin reuptake inhibitor (SSRI) used as an antidepressant and anxiolytic medication. It was developed in close cooperation between Lundbeck and Forest Laboratories. Escitalopram was first approved by the U.S. Food and Drug Administration (FDA) in August 2002, and the approval was granted to Forest Laboratories, which was later acquired by Allergan, now part of AbbVie. Now escitalopram is marketed under various brand names, including Lexapro, Cipralex, and Seroplex, and is available in tablet and oral solution forms. Its mechanism of action involves inhibition of the reuptake of the neurotransmitter serotonin in the brain, leading to increased levels of serotonin in the synaptic cleft and enhancement of serotonergic neurotransmission. This ultimately leads to improvement in mood and reduction in anxiety symptoms. Escitalopram was originally developed and approved for the treatment of Major Depressive Disorder (MDD). It has since been approved for the treatment of Generalized Anxiety Disorder (GAD) as well.
