Name: Unoprostone

Unoprostone Overview

Unoprostone is a prescription medication used to treat increased eye pressure in patients with glaucoma or ocular (eye) hypertension. Unoprostone belongs to a group of drugs called prostaglandins, which help to decrease the amount of fluid build-up in the eye.

This medication comes in eye drop solution form and is taken by placing one drop in the affected eye twice daily.

Common side effects of unoprostone include burning or stinging upon use, dry eyes, itching, and increased length of eyelashes.

Concerns related to adverse effects:

• Ocular pigmentation: May cause permanent change in eye color (increases the amount of brown pigment in the iris, may not be noticeable for months to years); long-term consequences and potential injury to eye are not known. May also cause pigment changes to periorbital tissues and eyelashes during use; reversible upon discontinuation in most patients.

• Infection: Bacterial keratitis, caused by inadvertent contamination of multiple-dose ophthalmic solutions, has been reported. Minimize contamination by not touching the eyelids or surrounding areas with the dropper tip; keep bottle tightly closed when not in use.

Disease-related concerns:

• Ocular disease: Use with caution in patients with intraocular inflammation (eg, uveitis); may exacerbate intraocular inflammatory conditions. May cause macular edema, including cystoid macular edema; use cautiously in aphakic patients, pseudophakic patients with torn posterior lens capsules, or in patients at risk for macular edema.

Special populations:

• Contact lens wearers: Contains benzalkonium chloride which may be adsorbed by contact lenses; remove contacts prior to administration and wait 15 minutes before reinserting.

Dosage form specific issues:

• Contains benzalkonium chloride 0.015% as a preservative.
