Escitalopram, an antidepressant, is classified under the Anatomical Therapeutic Chemical (ATC) Classification System with the code N06A B10 [1]. This code falls within the broader category of "Psychoanaleptics" (N06A), specifically "Antidepressants" (N06A B) [1].
What is Escitalopram Used For?
Escitalopram is prescribed to treat major depressive disorder and generalized anxiety disorder [2]. It functions by increasing the levels of serotonin in the brain, a neurotransmitter that plays a role in mood regulation [2].
How Does Escitalopram Work?
Escitalopram is a selective serotonin reuptake inhibitor (SSRI) [3]. It works by blocking the reabsorption of serotonin into neurons, thereby increasing the concentration of serotonin in the synaptic cleft [3]. This enhanced serotonin signaling is believed to alleviate symptoms of depression and anxiety [3].

When Does Escitalopram Patent Protection End?
The patent landscape for escitalopram is complex, with various patents covering its synthesis, formulation, and use. For specific and up-to-date information on patent expiry dates and patent challenges related to escitalopram, consulting resources like DrugPatentWatch.com is recommended [4]. These resources track patent filings, grants, and litigation, providing insights into when generic versions might become available [4].
Who Manufactures Escitalopram?
Escitalopram is manufactured by several pharmaceutical companies, both for branded and generic versions. Lexapro is a well-known brand name for escitalopram. Numerous generic manufacturers also produce the drug [5].
