Anti-glaucoma alpha-2 adrenergic agonist eye drops
Description
Brimonidine Tartrate 2 mg/ml Eye Drops, solution is a preserved ophthalmic solution containing brimonidine tartrate 2 mg/ml (equivalent to 1.3 mg/ml brimonidine), an alpha-2 adrenergic receptor agonist. It is indicated for the reduction of elevated intraocular pressure (IOP) in patients with open-angle glaucoma or ocular hypertension, either as monotherapy when topical beta-blocker therapy is contraindicated or as adjunctive therapy when additional IOP lowering is required. The solution is clear, slightly greenish-yellow, with a pH between 5.5–6.5 and osmolality 275–315 mOsm/kg, supplied in 5 ml LDPE dropper bottles for ocular use.
Bnefits
- Reduces elevated intraocular pressure in patients with open-angle glaucoma or ocular hypertension.
- Can be used as monotherapy when topical beta-blocker eye drops are contraindicated.
- Provides an additional intraocular pressure-lowering effect when used as adjunctive therapy to other ocular hypotensive agents.
- Rapid onset of action, with peak ocular hypotensive effect around two hours after dosing.
- Demonstrated long-term intraocular pressure reduction of approximately 4–6 mmHg in clinical studies with continued twice-daily use.
- Topical administration with generally minimal effects on cardiovascular and pulmonary parameters when used as directed.
Indications
- Reduction of elevated intraocular pressure (IOP) in patients with open-angle glaucoma.
- Reduction of elevated intraocular pressure in patients with ocular hypertension.
- Monotherapy in patients in whom topical beta-blocker therapy is contraindicated.
- Adjunctive therapy to other intraocular pressure-lowering medications when target IOP is not achieved with a single agent.
Composition
- Active ingredient: Brimonidine tartrate 2 mg/ml (equivalent to 1.3 mg/ml brimonidine).
- Excipient with known effect: Benzalkonium chloride 0.05 mg/ml (preservative).
- Other excipients: Poly(vinyl) alcohol, sodium chloride, sodium citrate, citric acid monohydrate, purified water, hydrochloric acid (dilute, for pH adjustment), sodium hydroxide (for pH adjustment).
Formulation
- Eye drops, solution.
- Clear, slightly greenish-yellow, preserved aqueous ophthalmic solution with pH 5.5–6.5 and osmolality 275–315 mOsm/kg.
Packaging
- 5 ml solution in low-density polyethylene (LDPE) dropper bottles with LDPE dropper tip (approximately 35 microlitre drop) and high-density polyethylene (HDPE) cap.
- Pack sizes: 1 × 5 ml, 3 × 5 ml, or 6 × 5 ml bottles (not all pack sizes may be marketed).
Usage
- Adults (including the elderly): instil one drop into the affected eye(s) twice daily, approximately 12 hours apart, or as directed by the prescribing clinician.
- Wash hands before use. Tilt the head back, gently pull down the lower eyelid to form a pouch and instil one drop into the conjunctival sac, taking care not to touch the eye or surrounding structures with the dropper tip.
- After instillation, gently press a finger on the inner corner of the eye (medial canthus) to occlude the lacrimal sac for about one minute to reduce systemic absorption.
- If more than one topical ophthalmic medicinal product is being used, administer each at least 5–15 minutes apart.
- Soft contact lenses should be removed before instillation and may be reinserted after at least 15 minutes, as benzalkonium chloride may be absorbed by and discolour soft lenses.
- Use exactly as prescribed. Do not stop treatment without consulting the doctor, as intraocular pressure may rise again.
Contraindications
- Hypersensitivity to brimonidine tartrate or to any of the excipients listed in the product.
- Use in neonates and infants (less than 2 years of age).
- Patients receiving monoamine oxidase (MAO) inhibitor therapy.
- Patients taking antidepressants that affect noradrenergic transmission, such as tricyclic antidepressants or mianserin.
Adverse Effects
- Very common: headache, drowsiness; ocular irritation (including hyperaemia, burning and stinging, pruritus, foreign body sensation, conjunctival follicles); blurred vision; allergic blepharitis, allergic blepharoconjunctivitis, allergic conjunctivitis, ocular allergic reactions; oral dryness; fatigue.
- Common: dizziness, abnormal taste; local eye irritation (eyelid hyperaemia and oedema, blepharitis, conjunctival oedema and discharge, ocular pain and tearing); photophobia; corneal erosion and staining; ocular dryness; conjunctival blanching; abnormal vision; conjunctivitis; upper respiratory symptoms; gastrointestinal symptoms; asthenia.
- Uncommon: systemic allergic reactions; depression; palpitations or arrhythmias (including bradycardia and tachycardia); nasal dryness.
- Rare: dyspnoea.
- Very rare: insomnia; iritis; miosis; hypertension; hypotension.
- Frequency not known (post-marketing): iridocyclitis (anterior uveitis); eyelid pruritus; skin reactions including erythema, facial oedema, pruritus, rash and vasodilation.
- Paediatric population: in children aged 2–7 years, particularly those weighing ≤20 kg, a high incidence of somnolence (including severe cases) has been reported when used as adjunctive therapy; serious systemic adverse effects including CNS depression have been reported following accidental ingestion in children.
