Description
Co-Dorzal Eye Drops 5ml
Product Overview
Co-Dorzal Eye Drops is a prescription ophthalmic solution containing a fixed-dose combination of Dorzolamide (2%) and Timolol (0.5%). Marketed by Sante Pharma in Pakistan, this advanced combination therapy is specifically designed for the reduction of elevated intraocular pressure (IOP) in patients with open-angle glaucoma or ocular hypertension. Co-Dorzal works through two complementary mechanisms: dorzolamide, a carbonic anhydrase inhibitor, reduces aqueous humor production, while timolol, a beta-blocker, further decreases aqueous humor formation. Together, they effectively lower intraocular pressure, helping to prevent damage to the optic nerve and preserve vision. Administered as a simple topical eye drop, Co-Dorzal offers a convenient and effective treatment option for patients requiring combination therapy. Each pack contains 5ml of sterile ophthalmic solution.
This advanced combination therapy delivers effective intraocular pressure reduction and optic nerve protection:
Effective IOP Reduction: Combines two complementary agents for superior reduction of elevated intraocular pressure.
Open-Angle Glaucoma Management: Indicated for the treatment of open-angle glaucoma, a condition characterized by progressive optic nerve damage.
Ocular Hypertension Treatment: Effectively lowers elevated eye pressure in patients with ocular hypertension.
Dual Mechanism of Action: Dorzolamide reduces aqueous humor production through carbonic anhydrase inhibition, while timolol further decreases aqueous humor formation through beta-blockade.
Convenient Twice-Daily Dosing: Simple, twice-daily topical administration for consistent and effective treatment.
Prescription Medication: Requires a prescription from a qualified healthcare professional, typically an ophthalmologist.
What are the Primary Uses and Key Features of Co-Dorzal Eye Drops?
Co-Dorzal Eye Drops serves as a specialized therapeutic solution for managing elevated intraocular pressure. It is designed to effectively reduce eye pressure and protect the optic nerve from damage.
Core Uses of This Medication
Open-Angle Glaucoma: The primary indication is the treatment of open-angle glaucoma, a chronic, progressive optic neuropathy characterized by elevated intraocular pressure, optic nerve damage, and visual field loss.
Ocular Hypertension: Indicated for the reduction of elevated intraocular pressure in patients with ocular hypertension who are at risk of developing glaucoma.
Combination Therapy: Used when monotherapy with either dorzolamide or timolol alone is insufficient to achieve target intraocular pressure levels.
Replacement Therapy: May be used to replace individual components in patients who are already stabilized on the same doses of dorzolamide and timolol.
Optic Nerve Protection: By effectively lowering intraocular pressure, helps prevent damage to the optic nerve and preserve vision.

What Key Ingredients are in Co-Dorzal Eye Drops and How Does It Work?
Composition
| Component | Description |
|---|---|
| Dorzolamide | Each ml contains 20mg (2%) of dorzolamide (as dorzolamide hydrochloride). |
| Timolol | Each ml contains 5mg (0.5%) of timolol (as timolol maleate). |
| Other Ingredients | Contains pharmaceutical excipients including benzalkonium chloride (preservative), sodium citrate, and sodium hydroxide. |
Mechanism of Action
Co-Dorzal combines two complementary agents that reduce intraocular pressure through different mechanisms:
Dorzolamide is a potent, selective inhibitor of carbonic anhydrase II, an enzyme found primarily in the ciliary processes of the eye. By inhibiting carbonic anhydrase, dorzolamide reduces the formation of bicarbonate ions, which in turn reduces sodium and fluid transport across the ciliary epithelium. This results in a decrease in aqueous humor production and a consequent reduction in intraocular pressure.
Timolol is a non-selective beta-adrenergic receptor antagonist (beta-blocker) that reduces intraocular pressure by decreasing aqueous humor formation. The exact mechanism is believed to involve the blockade of beta-receptors in the ciliary epithelium, which reduces the production of aqueous humor.
Together, these two mechanisms provide effective and complementary reduction of intraocular pressure, lowering pressure more effectively than either agent alone.
Key Benefits
Effectively lowers elevated intraocular pressure.
Reduces the risk of optic nerve damage and vision loss.
Convenient twice-daily fixed-dose combination.
Well-tolerated with complementary mechanisms.
Proven efficacy in open-angle glaucoma and ocular hypertension.
How Should I Use Co-Dorzal Eye Drops Correctly?
Co-Dorzal Eye Drops must be used exactly as prescribed by a healthcare professional, typically an ophthalmologist. Do not self-adjust the dose.
Dosage and Administration
| Parameter | Details |
|---|---|
| Recommended Dose (Adults) | One drop in the affected eye(s) twice daily. |
| Frequency | Approximately 12 hours apart (e.g., morning and evening). |
| Maximum Dose | One drop twice daily in each affected eye. |
| Method of Administration | Topical application to the eye(s). |
| Duration | Chronic therapy is typical; continue as prescribed by your doctor. |
Method of Administration
Wash your hands thoroughly before use.
Remove the protective cap from the bottle.
Tilt your head back slightly and pull down your lower eyelid to create a small pocket.
Hold the bottle upside down and gently squeeze to release one drop into the pocket of the affected eye(s).
Close your eye gently and press the inner corner of your eye (near the nose) for 1-2 minutes. This helps prevent the solution from draining into the tear duct and reduces the risk of systemic side effects.
Wipe away any excess solution with a clean tissue.
Replace the protective cap immediately after use.
Important Considerations
Prescription Only: This medication is available only with a prescription.
For Ophthalmic Use Only: Do not swallow or inject the solution.
Do Not Touch: Do not allow the tip of the bottle to touch the eye, eyelid, or any surface to avoid contamination.
Contact Lenses: Remove contact lenses before application and wait at least 15 minutes before reinserting. The preservative benzalkonium chloride may be absorbed by soft contact lenses.
Systemic Absorption: Pressing the inner corner of the eye (nasolacrimal occlusion) for 1-2 minutes reduces systemic absorption and minimizes side effects.
What Precautions Should I Be Aware of Before Using This Medication?
While generally safe and well-tolerated, specific conditions and interactions require awareness and caution.
Key Warnings and Contraindications
Hypersensitivity: Contraindicated in patients with known hypersensitivity to dorzolamide, timolol, or any excipients.
Respiratory Conditions: Contraindicated in patients with bronchial asthma, severe COPD, or a history of bronchial asthma.
Cardiac Conditions: Contraindicated in patients with sinus bradycardia, second- or third-degree atrioventricular block, overt cardiac failure, or cardiogenic shock.
Severe Renal Impairment: Use with caution; dorzolamide is excreted primarily by the kidneys.
Pregnancy and Lactation: Consult your doctor before use if you are pregnant, planning to become pregnant, or breastfeeding.
Sulfonamide Sensitivity: Dorzolamide is a sulfonamide derivative; use with caution in patients with sulfonamide sensitivity.
Diabetes: Timolol may mask the symptoms of hypoglycemia (tachycardia) in diabetic patients.
Thyrotoxicosis: Timolol may mask the symptoms of hyperthyroidism.
