BRIMOCOM EYE DROP

👁️💧🔒 Timolol 5mg + Brimonidine 2mg Eye Drops: Dual Action Control for Elevated Intraocular Pressure

Timolol 5mg + Brimonidine 2mg is a combination ophthalmic solution widely used in the treatment of elevated intraocular pressure (IOP), particularly in conditions like open-angle glaucoma and ocular hypertension. By combining two different classes of drugs, this medication offers synergistic pressure-lowering effects, helping to preserve vision and slow the progression of optic nerve damage.

🧪 Composition and Mechanism of Action

This fixed-dose combination includes:

• Timolol (5mg/ml) – a non-selective beta-blocker

• Brimonidine (2mg/ml) – an alpha-2 adrenergic agonist

Timolol works by reducing aqueous humor production in the eye, thereby lowering intraocular pressure.
Brimonidine also decreases aqueous humor production and increases uveoscleral outflow, providing a dual mechanism of IOP control.

Together, these agents offer enhanced efficacy compared to monotherapy and may reduce the need for surgery or additional medications.

📌 Indications and Clinical Use

This combination is typically prescribed when monotherapy is insufficient in controlling IOP. Indications include:

• Primary open-angle glaucoma (POAG)

• Ocular hypertension

• Angle closure glaucoma (as adjunct therapy)

• Situations requiring stronger or faster IOP reduction

---

💧 Dosage and Administration

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

• Use consistently at the same times each day.

• Contact lenses should be removed before instillation and reinserted after 15 minutes.

Proper drop technique is crucial:

• Wash hands before use

• Avoid touching dropper tip to eye or any surface

• After administration, press the inner corner of the eye (nasolacrimal duct) for 1–2 minutes to reduce systemic absorption.

⚠️ Precautions and Warnings

Systemic absorption may cause side effects due to the beta-blocker (timolol), especially in sensitive individuals. Use with caution in patients with:

• Asthma or COPD (may cause bronchospasm)

• Bradycardia or heart block

• Depression

• Vascular insufficiency (Raynaud’s)

Avoid abrupt discontinuation, especially in patients with heart conditions.

❗ Side Effects

Ocular:

• Eye irritation or dryness

• Redness or allergic conjunctivitis

• Blurred vision

• Eye fatigue

Systemic:

• Fatigue or drowsiness (from brimonidine)

• Slowed heart rate or hypotension (from timolol)

• Dry mouth, headache

Rare but serious:

• Respiratory difficulty

• Depression or mood changes

• Allergic reactions

---

🔄 Drug Interactions

• Caution with oral beta-blockers (additive effects)

• CNS depressants can enhance brimonidine’s sedative effects

• Monoamine oxidase inhibitors (MAOIs) may interfere with brimonidine’s action

• Risk of systemic hypotension with antihypertensive medications

---

🧊 Storage Instructions

• Store at 15–25°C, away from light and moisture

• Do not freeze

• Discard bottle 4 weeks after opening to avoid contamination

✅ Conclusion

Timolol 5mg + Brimonidine 2mg eye drops offer a powerful dual-action approach to lowering intraocular pressure in glaucoma and ocular hypertension. By combining reduced fluid production and increased drainage, this combination enhances efficacy, improves compliance, and reduces the need for additional therapies. Regular monitoring and correct application are essential to achieving optimal long-term vision preservation.
