Xiidra emerges as a pivotal prescription medication for those battling dry eye disease, offering a targeted approach to inflammation rather than temporary relief. With lifitegrast as its active ingredient, Xiidra disrupts the inflammatory cycle, providing effective symptom management. Explore the intricacies of its formulation, clinical efficacy, and potential side effects to make informed decisions about eye health.
Understanding Xiidra and Its Ingredients
Xiidra is a prescription medication specifically designed to treat dry eye disease, a condition that affects millions of people worldwide. Approved by the FDA in July 2016, Xiidra offers a therapeutic approach that targets the underlying inflammation causing dry eye symptoms, unlike over-the-counter artificial tears that only provide temporary relief (source). The active ingredient in Xiidra is lifitegrast, which functions as a lymphocyte function-associated antigen-1 (LFA-1) antagonist. This mechanism helps interrupt the inflammatory cycle by preventing T-cells from releasing cytokines that cause irritation and damage to the eye surface (source).
The Role of Lifitegrast in Eye Health
Lifitegrast, the active ingredient in Xiidra, is present at a concentration of 50 mg/mL. It is specifically formulated to treat the signs and symptoms of dry eye disease by targeting inflammation, a common cause of chronic dry eye (source). By preventing the interaction between two proteins, LFA-1 and ICAM-1, involved in T cell activity, lifitegrast reduces immune system activation and inflammation associated with dry eye disease (source).
Inactive Ingredients and Their Functions
In addition to lifitegrast, Xiidra contains several inactive ingredients that help maintain the stability and efficacy of the solution. These include sodium chloride, sodium phosphate dibasic anhydrous, sodium thiosulfate pentahydrate, sodium hydroxide and/or hydrochloric acid (to adjust pH), and water for injection (source). These components ensure that the medication remains effective and safe for use over time.
Clinical Efficacy and Usage
Clinical studies have demonstrated that Xiidra can start providing symptom relief for dry eye disease in as little as two weeks with continued twice-daily use. Improvements were observed at 6 and 12 weeks in all four studies conducted (source). Proper administration involves using the medication twice daily, approximately 12 hours apart, to ensure consistent therapeutic effects. The medication is packaged in single-use vials to maintain sterility and prevent contamination (source).
Side Effects and Considerations
Common side effects of Xiidra include a brief stinging or burning sensation upon application, an unusual taste in the mouth, and mild eye redness. These effects are generally mild and temporary, but any persistent or severe reactions should be discussed with an eye care provider (source). Additionally, Xiidra is covered by many insurance plans, making it a financially accessible option for many patients suffering from dry eye disease (source).
