BRIMOLOL EYE DROP

👁️💧🛡️ Timolol 5mg + Brimonidine 1.5mg Eye Drops: Dual-Action Relief for Intraocular Pressure

Timolol 5mg + Brimonidine 1.5mg is a fixed-dose combination ophthalmic solution used primarily for the treatment of elevated intraocular pressure (IOP) in individuals with open-angle glaucoma or ocular hypertension. This combination provides enhanced pressure-lowering effects by combining two well-known agents with complementary mechanisms of action. It is prescribed when a single medication does not sufficiently control eye pressure.

🔬 Mechanism of Action

1. Timolol (5mg): A non-selective beta-adrenergic blocker, timolol reduces aqueous humor (fluid) production in the eye, leading to lower IOP.

2. Brimonidine (1.5mg): An alpha-2 adrenergic agonist, brimonidine both reduces aqueous humor production and enhances uveoscleral outflow, further reducing IOP.

Together, they provide a dual-action effect—decreasing the fluid entering and increasing the fluid exiting the eye, offering superior pressure control.

👁️ Therapeutic Uses

• Primary open-angle glaucoma – To prevent optic nerve damage caused by raised intraocular pressure.

• Ocular hypertension – Reduces risk of progression to glaucoma.

• Ideal for patients not adequately responding to monotherapy.

This combination can delay or prevent vision loss by effectively managing eye pressure, a major risk factor in glaucoma.

💧 Dosage and Administration

• Usually instilled one drop in the affected eye(s) twice daily, approximately 12 hours apart.

• Do not touch the dropper tip to any surface to avoid contamination.

• After applying, press gently at the corner of the eye (nasolacrimal duct) for 1-2 minutes to improve absorption and reduce systemic side effects.

• If using other eye drops, maintain a 5–10 minute gap between applications.

⚠️ Precautions and Warnings

• Use with caution in patients with:

  • Asthma, COPD, or heart block (timolol may worsen respiratory/cardiac conditions)

  • Depression or low blood pressure (brimonidine can affect CNS and blood pressure)

• Not recommended for children under 2 years

• Pregnancy and breastfeeding: Only use if prescribed by a doctor.

• Avoid driving or operating machinery if blurred vision or drowsiness occurs after use.

🤒 Side Effects

Common:

• Eye irritation, burning, or stinging

• Dry eyes or blurred vision

• Fatigue or drowsiness

• Mild headache

Serious (seek medical attention):

• Slow or irregular heartbeat

• Breathing difficulty

• Allergic reactions (swelling, rash, severe eye redness)

• Depression or mood changes (rare)

🔄 Drug Interactions

• Caution with:

  • Other beta-blockers or antihypertensives (can lead to additive effects)

  • CNS depressants or alcohol (increases drowsiness)

  • MAO inhibitors or tricyclic antidepressants (may intensify brimonidine effects)

Inform your doctor about all current medications before starting treatment.

🧊 Storage Instructions

• Store at room temperature (15–25°C) away from light and moisture.

• Do not freeze.

• Use within 28 days after opening the bottle.

• Keep out of reach of children.
