Fluorometholone

Fluorometholone is a synthetic glucocorticoid used in the treatment of inflammatory eye diseases. It is a white, crystalline powder that is practically insoluble in water. Fluorometholone works by reducing inflammation and suppressing the immune response in the eye, making it effective in treating conditions such as keratitis, conjunctivitis, and post-operative inflammation. It is available in various formulations, including eye drops and ointment.

Pharmacology

Fluorometholone binds to glucocorticoid receptors, leading to changes in gene expression that result in decreased inflammation. Its effects are due to the inhibition of inflammatory cells and suppression of the production of inflammatory mediators. Fluorometholone has a higher potency and a longer duration of action compared to hydrocortisone, but a lower potency than dexamethasone.

Indications

Fluorometholone is indicated for the treatment of corticosteroid-responsive inflammation of the palpebral and bulbar conjunctiva, cornea, and anterior segment of the globe. It is also used in managing chronic conditions such as uveitis and in the prevention of post-operative eye inflammation.

Side Effects

The use of fluorometholone, like other corticosteroids, can lead to side effects. The most common include increased intraocular pressure, which can lead to glaucoma, and the formation of cataracts. Other potential side effects include delayed wound healing, secondary eye infections, and in rare cases, perforation of the globe. Patients are advised to use fluorometholone under the supervision of a healthcare professional to monitor for these side effects.

Contraindications

Fluorometholone is contraindicated in individuals with known hypersensitivity to the drug or any of its components. It should not be used in the presence of untreated bacterial, viral, or fungal eye infections due to the risk of exacerbating these conditions.

Administration and Dosage

The dosage of fluorometholone varies depending on the severity of the condition being treated. For mild to moderate inflammation, the typical dosage is one to two drops applied to the affected eye up to four times daily. In more severe cases, the dosage may be increased as directed by a healthcare professional. It is important to follow the prescribed dosage and duration of treatment to minimize the risk of side effects.

Pharmacokinetics

Fluorometholone is minimally absorbed into the systemic circulation when applied topically to the eye. Its local effects are primarily due to its action at the site of application. The metabolism and excretion of fluorometholone occur primarily in the liver.

Interactions

Fluorometholone may interact with other medications, particularly other eye medications. It is important to inform healthcare providers of all medications being used to avoid potential interactions. The use of multiple eye medications should be spaced out to prevent dilution and ensure the effectiveness of each medication.

Conclusion

Fluorometholone is an effective treatment for inflammatory eye conditions, offering relief from symptoms and aiding in the recovery process. However, its use must be carefully managed to avoid potential side effects and interactions with other medications. Patients should always consult with a healthcare professional before starting treatment with fluorometholone.
