Dexamethasone sodium phosphate ophthalmic solution is a corticosteroid used in veterinary medicine to treat eye inflammation in dogs. It is effective in reducing swelling, redness, and discomfort caused by conditions like conjunctivitis, keratitis, and post-surgical inflammation. This medication is crucial for managing eye conditions and ensuring the comfort and health of pets.
Mechanism of Action
Dexamethasone sodium phosphate ophthalmic solution is a corticosteroid used in dogs to reduce inflammation in the eyes. It works by suppressing the immune response, which decreases swelling, redness, and itching. This makes it effective for treating conditions like conjunctivitis, keratitis, and post-surgical inflammation.
Indications
Dexamethasone sodium phosphate ophthalmic solution is prescribed for several specific eye conditions in dogs, including:
- Conjunctivitis: Inflammation of the conjunctiva, the membrane covering the white part of the eye and the inner eyelids.
- Keratitis: Inflammation of the cornea, the clear front surface of the eye.
- Iritis: Inflammation of the iris, the colored part of the eye.
- Cyclitis: Inflammation of the ciliary body, part of the eye involved in focusing.
- Allergic Conjunctivitis: Inflammation caused by allergies.
- Acne Rosacea: A condition that can cause inflammation of the eyes.
- Superficial Punctate Keratitis: A condition where the cornea has small, superficial erosions.
- Herpes Zoster Keratitis: Inflammation caused by the herpes zoster virus.
- Corneal Injury: Inflammation due to chemical or thermal burns, or penetration of foreign bodies.
Dosage and Administration
For dogs, the recommended dosage of dexamethasone sodium phosphate ophthalmic solution is typically 1-2 drops instilled into the affected eye(s) every hour during the day and every two hours during the night initially. Once a favorable response is observed, the dosage can be reduced to 1 drop every 4 hours. Further reduction to 1 drop 3-4 times daily may suffice to control symptoms.
