Brinzolamide ophthalmic suspension 1% effectively lowers intraocular pressure (IOP) in primary open-angle glaucoma patients. This treatment demonstrated safety and tolerability, with no significant impact on corneal health or systemic parameters.
Area of Science:
- Ophthalmology
- Pharmacology
Background:
- Primary open-angle glaucoma (POAG) is a progressive optic neuropathy.
- Elevated intraocular pressure (IOP) is the main risk factor for POAG and optic nerve head (ONH) damage.
- IOP is the only treatable risk factor for POAG.
Purpose of the Study:
- To evaluate the efficacy and safety of brinzolamide ophthalmic suspension 1% in managing IOP.
- To assess the impact of brinzolamide on retinal blood flow.
- To determine the effects of brinzolamide on corneal parameters and systemic health.
Main Methods:
- Clinical trials involving patients with POAG.
- Administration of brinzolamide ophthalmic suspension 1% as monotherapy, adjunctive therapy, or post-cataract surgery.
- Monitoring of IOP, retinal blood flow, corneal thickness, corneal endothelium cell density, heart rate, blood pressure, and laboratory values.
Main Results:
- Brinzolamide ophthalmic suspension 1% reduced IOP by up to 18% from baseline.
- Retinal blood flow showed improvement with brinzolamide treatment.
- No significant changes in corneal thickness or endothelium cell density were observed after 18 months.
- Adverse events were mild and nonserious, with taste perversion being the most common non-ocular event.
- No clinically significant systemic effects on heart rate, blood pressure, or laboratory values were detected.
Conclusions:
- Brinzolamide ophthalmic suspension 1% is an effective topical carbonic anhydrase inhibitor for lowering IOP in POAG.
- The treatment is well-tolerated with a favorable safety profile regarding ocular and systemic parameters.
- Brinzolamide offers a safe and effective option for IOP management in POAG patients.

Melatonin congeners like ramelteon (Rozerem) and tasimelteon (Hetlioz) selectively bind to melatonin receptors (MT1 and MT2) and thus mimic the actions of melatonin, a hormone that regulates sleep-wake cycles. Tasimelteon is primarily used for non-24-hour sleep-wake disorder, common in blind patients. They are also used to treat conditions like insomnia...
