What Is Escitalopram and Its Therapeutic Profile?
Escitalopram is a selective serotonin reuptake inhibitor (SSRI) approved for treating major depressive disorder (MDD), generalized anxiety disorder (GAD), and obsessive-compulsive disorder (OCD). It is marketed under brand names such as Lexapro and Cipralex, among others. Approved by the FDA in 2002, it is a chiral molecule, with the S-enantiomer exhibiting antidepressant activity.

Growth Rate
The compound annual growth rate (CAGR) for the antidepressants market, driven by escitalopram, stood at 3-4% from 2018 to 2022. The growth is driven by increased prevalence of depression and anxiety, especially post-pandemic, and the expansion into emerging markets.
Patent Landscape and Market Dynamics
Patent Expiration Timeline
Pfizer's patent for Lexapro expired in the U.S. in 2012, with subsequent US patent protections ending in 2018. The off-patent status has spurred generic competition, leading to price reductions:
- Original patent: 2002–2012
- Patent expiry leading to generics: 2012–present
Impact of Patent Expiry
Generic versions account for approximately 80-90% of sales volume but at significantly lower prices, reducing brand revenue:
- Original product price: USD 10-15 per prescription
- Generics price: USD 4-7 per prescription
Emerging Markets
In countries like India and Brazil, regulatory approval of generics and biosimilars has accelerated, contributing to increased volume but lower margins.
