What is Copred?
Copred is a brand-name ophthalmic suspension containing the active ingredient Loteprednol etabonate, a topical corticosteroid designed to reduce eye inflammation. Unlike oral steroids, Copred acts locally in the eye, minimizing systemic side effects. It is a prescription medication used under medical supervision.
The Core Function: What Does Copred Do?
Copred is an anti-inflammatory medication for the eye, primarily addressing redness, swelling, itching, and pain from various eye conditions. It helps resolve symptoms and aids healing by targeting the root cause of inflammation triggered by surgery, allergies, or infections.
Mechanism of Action
Copred's active ingredient, Loteprednol etabonate, is a corticosteroid that reduces inflammation by blocking chemical messengers called prostaglandins. Prostaglandins cause blood vessel dilation, leading to redness and swelling. Loteprednol etabonate is a 'soft-drug' or 'retrometabolic' steroid designed to be effective locally and then quickly metabolized into inactive compounds, reducing the risk of side effects like elevated intraocular pressure (IOP) associated with prolonged steroid use. This gives it a better safety profile for IOP compared to some older corticosteroids.
Common Medical Applications of Copred
Copred is used for several steroid-responsive inflammatory conditions of the eye, including post-operative inflammation after eye surgeries, seasonal allergic conjunctivitis, and other inflammatory conditions of the cornea, conjunctiva, and anterior segment under medical supervision. Combination products like Copred-M include an antibiotic (Moxifloxacin) to treat inflammation alongside a bacterial infection.
How to Use Copred Eye Drops Correctly
Proper administration involves washing hands, shaking the bottle, tilting the head back, creating a lower eyelid pouch, instilling the prescribed drops without touching the eye, closing the eye gently, and applying pressure to the tear duct. Wait 5-10 minutes before using other eye drops. Always follow your doctor's instructions.
Key Precautions and Potential Side Effects
Potential side effects of Copred include eye irritation, temporary blurred vision, and headache. More serious risks with prolonged use include increased intraocular pressure and cataract formation. Steroids can also increase the risk of secondary eye infections and delay healing. Copred should generally be avoided with most viral, mycobacterial, or fungal eye infections. Soft contact lenses should be removed before use, waiting 15 minutes before reinserting them. Blurred vision may impair driving.
Comparing Copred (Loteprednol) to Prednisolone
Both Loteprednol etabonate (Copred) and prednisolone acetate are ophthalmic steroids. Loteprednol has a lower risk of increasing intraocular pressure due to its rapid metabolism compared to prednisolone. While prednisolone can be more potent for severe uveitis, Loteprednol is often preferred for longer-term use due to a better safety profile regarding IOP and cataract risk.
| Feature | Loteprednol Etabonate (Copred) | Prednisolone Acetate |
|---|---|---|
| Active Ingredient | Loteprednol etabonate | Prednisolone acetate |
| IOP Elevation Risk | Lower | Higher |
| Systemic Absorption | Low | Can be greater |
| Efficacy in Uveitis | Effective, potentially less potent than prednisolone in acute anterior uveitis | Often more potent for severe anterior uveitis |
| Safety Profile | More favorable for IOP and cataracts with long-term use | Higher risks for IOP and steroid-related complications |

Conclusion
Copred is a prescription ophthalmic steroid used for eye inflammation from surgery, allergies, or certain infections. Its active ingredient, Loteprednol etabonate, offers a lower risk of increased intraocular pressure compared to some older steroids. However, it is potent, has potential side effects, and is not for long-term use. Following your doctor's instructions and attending follow-up appointments are crucial for safe use.
