treatment with dorzolamide/timolol
Dorzolamide/timolol is a fixed-dose combination that reduces intraocular pressure by inhibiting carbonic anhydrase (dorzolamide) and blocking beta-adrenergic receptors (timolol).
Dorzolamide/timolol is a fixed-dose combination that reduces intraocular pressure by inhibiting carbonic anhydrase (dorzolamide) and blocking beta-adrenergic receptors (timolol). Used for Open-angle glaucoma, Ocular hypertension.
At a glance
| Generic name | treatment with dorzolamide/timolol |
|---|---|
| Sponsor | Aristotle University Of Thessaloniki |
| Drug class | Carbonic anhydrase inhibitor / Beta-blocker combination |
| Target | Carbonic anhydrase II; Beta-adrenergic receptors (β1 and β2) |
| Modality | Small molecule |
| Therapeutic area | Ophthalmology |
| Phase | FDA-approved |
Mechanism of action
Dorzolamide decreases aqueous humor production by inhibiting carbonic anhydrase II in the ciliary body, while timolol reduces aqueous humor production and increases uveoscleral outflow through non-selective beta-adrenergic receptor antagonism. Together, these complementary mechanisms provide additive intraocular pressure reduction.
