Brinzolamide: Brands, Price & Uses in Bangladesh

Brinzolamide ophthalmic suspension is a carbonic anhydrase inhibitor indicated for the treatment of elevated intraocular pressure (IOP) in patients with:

• Ocular hypertension - an FDA-approved, well-established indication.
• Open-angle glaucoma - an FDA-approved, well-established indication, used alone or as adjunctive therapy with other IOP-lowering agents (e.g., beta-blockers, prostaglandin analogs) when a single agent does not adequately control pressure.

Brinzolamide works by reducing the production of aqueous humor in the eye, thereby lowering IOP and reducing the risk of optic nerve damage and vision loss associated with glaucoma.

Administration instructions:

• Shake the bottle well before each use.
• Tilt the head back, pull down the lower eyelid, and instill one drop into the affected eye(s), avoiding contact of the dropper tip with the eye or surrounding surfaces to prevent contamination.
• If using more than one topical ophthalmic medication, space administration at least 10 minutes apart.
• Contact lenses should be removed prior to instillation and may be reinserted 15 minutes after administration (see Precautions).

The most common side effects of Brinzolamide (occurring in 5-10% of patients) are:

• Blurred vision
• Bitter, sour, or unusual taste (dysgeusia) in the mouth after instillation

Less common side effects (1-5%) include:

• Eye discomfort, stinging, or burning on instillation
• Eye redness (hyperemia)
• Blepharitis (eyelid inflammation)
• Eye dryness, itching, or discharge
• Headache
• Rhinitis (stuffy/runny nose)

Rare but serious side effects: Because Brinzolamide is a sulfonamide derivative, rare systemic hypersensitivity reactions have been reported post-marketing, including Stevens-Johnson syndrome and toxic epidermal necrolysis. Seek immediate medical attention for skin rash, blistering, or peeling.
