SIMBRINZA (brimonidine tartrate)

Carbonic Anhydrase Inhibitors Trial Activity: Declining
Ophthalmology Approved 2013-04-19

Simbrinza is a fixed-combination ophthalmic suspension consisting of a carbonic anhydrase inhibitor (brinzolamide) and an alpha-2 adrenergic receptor agonist (brimonidine tartrate). It is indicated for the reduction of elevated intraocular pressure (IOP) in patients with open-angle glaucoma or ocular hypertension. By effectively managing IOP, Simbrinza helps mitigate the risk of progressive optic nerve damage and glaucomatous visual field loss.

How SIMBRINZA Works

Simbrinza reduces intraocular pressure through two distinct mechanisms of action. Brinzolamide inhibits the enzyme carbonic anhydrase (specifically isoenzyme II) in the ciliary processes, which slows the formation of bicarbonate ions and subsequently reduces sodium and fluid transport, thereby decreasing aqueous humor secretion. Brimonidine tartrate functions as a dual-action agent that reduces aqueous humor production and increases uveoscleral outflow. Together, these components decrease the net volume of aqueous humor, leading to a significant reduction in IOP.

How We Calculate These Metrics

Trial Activity Stage

Measures the current development activity pattern based on trial phases, status, and trends. Important: This measures R&D activity, not commercial lifecycle.

Trial statuses: "Active" means recruiting or ongoing. "Completed" means reached planned endpoint. "Terminated" means stopped early—often due to safety, efficacy, or business reasons.

  • Growth: High proportion of early-phase trials (Phase 1/2), active development
  • Expansion: Significant Phase 3 activity, approaching or pursuing approvals
  • Mature: Substantial Phase 4 post-marketing studies
  • Stable: Mixed phase distribution, steady development
  • Declining: Low active trial ratio, reduced R&D investment
