Overview
Paroxetine Extended-Release (ER), marketed as Brisdelle and generic versions, is a selective serotonin reuptake inhibitor (SSRI) primarily indicated for depression, anxiety disorders, and hot flashes associated with menopause. Its market is influenced by patent status, regulatory approvals, competition, and manufacturing costs.
Market Scope and Key Players
- The global antidepressant market was valued at approximately $15 billion in 2022, with SSRIs accounting for roughly 65% of the market share.
- Paroxetine ER holds an estimated 4-6% share within the SSRI segment, with sales driven mainly through generic formulations.
- Major manufacturers include GlaxoSmithKline (original patent holder), Mylan, Teva, and Sandoz.
Patent and Regulatory Status
