An estimated 16 million adults in the U.S. are diagnosed with dry eye, a disease associated with inflammation that may eventually lead to damage to the surface of the eye. An eye care professional can diagnose dry eye disease based on signs and symptoms and determine management options, which could include the use of a prescription treatment.

About Xiidra^™ (lifitegrast ophthalmic solution) 5%

Xiidra^™ (lifitegrast ophthalmic solution) 5% is a prescription eye drop indicated for the treatment of signs and symptoms of dry eye disease. It is dosed twice per day, approximately 12 hours apart, in each eye. The active ingredient in Xiidra, lifitegrast, binds to the integrin lymphocyte function-associated antigen-1 (LFA-1), a cell surface protein found on leukocytes, and blocks the interaction of LFA-1 with its cognate ligand intercellular adhesion molecule-1 (ICAM-1). ICAM-1 may be overexpressed in corneal and conjunctival tissues in patients with dry eye disease. This interaction can contribute to the formation of an immunological synapse resulting in T-cell activation and migration to target tissues. In vitro studies demonstrated that lifitegrast may inhibit T-cell adhesion to ICAM-1 in a human T-cell line and may inhibit secretion of inflammatory cytokines in human peripheral blood mononuclear cells. The exact mechanism of action of lifitegrast in dry eye disease is not known. Xiidra is packaged in a foil pouch containing five low density polyethylene 0.2 mL single-use containers, and is supplied in a carton of 60 single use containers.

Important Safety Information
The most common side effects of Xiidra include eye irritation, discomfort or blurred vision when the drops are applied to the eyes, and an unusual taste sensation (dysgeusia). To help avoid eye injury or contamination of the solution, do not touch the container tip to your eye or any surface. If you wear contact lenses, remove them before using Xiidra and wait for at least 15 minutes before placing them back in your eyes.

It is not known if Xiidra is safe and effective in children under 17 years of age.

About Dry Eye Disease

Dry eye is a multifactorial disease of the tears and ocular surface. It is diagnosed by an eye care professional based on patient reported symptoms, such as eye dryness, overall eye discomfort, stinging, burning, a gritty feeling or fluctuating blurry vision, as well as signs, which can be objectively evaluated by an eye care professional through various tests to determine the presence of dry eye disease. Aging and gender are recognized as traditional risk factors of dry eye disease while modern risk factors include prolonged digital/computer screen time, contact lens wear and cataract or refractive surgery. Dry eye is an often chronic ocular disease associated with inflammation that may eventually lead to damage to the surface of the eye. Dry eye may be progressive and is a common complaint to eye care professionals.

Shire’s Commitment to Ophthalmics
