Products & Pipeline
Our portfolio spans marketed products and pipeline assets that reflect both our cardiometabolic heritage and our growing focus on eye care. This page provides a high-level view of the therapies and investigational assets we are responsible for in the United States, including their therapeutic areas and development status.

Eye care and ophthalmology
We are actively expanding our presence in ophthalmology with a pipeline focused on conditions that threaten vision, including glaucoma and elevated intraocular pressure. While specific candidates and timelines may evolve, our goal is to bring forward therapies that enable eye care professionals to slow disease progression, protect the optic nerve, and preserve quality of life for patients at risk of vision loss.
Conditions We Support:
- Glaucoma and elevated intraocular pressure
- Additional ocular conditions under clinical evaluation

Ophthalmic & medical equipment
We are part of the Electronics and Optics division of Kowa Company Limited, known as Kowa Optimed. Kowa has become a brand known to the Western Hemisphere for high-quality precision optics able to perform in even the most extreme conditions. The company's focus on leading-edge technology, flexible machine technology, application software, and traditional optical technology produces a wide range of products designed to provide vision solutions and diagnostics for all users.
Ophthalmic Diagnostics:
Cardiometabolic and anti-inflammatory therapeutics
Kowa Pharmaceuticals America, Inc. also has a heritage rooted in cardiometabolic and anti-inflammatory therapeutics. While eye care is our primary focus going forward, we continue to support appropriate use of select legacy products and partnerships in these areas.
Before Kowa sharpened its focus on eye care, we built a strong foundation in cardiometabolic health.
