Question 1

What is Lifitegrast?

Accepted Answer

Lifitegrast is a medication classified as a lymphocyte function-associated antigen-1 (LFA-1) antagonist. It works by interfering with specific proteins on the surface of cells that contribute to inflammation.

By reducing this inflammation, the medication helps to manage the clinical signs and symptoms of dry eye disease. It is used to provide relief from the persistent discomfort and irritation associated with chronic dry eye conditions.

Question 2

Lifitegrast is used to treat dry eye disease .

Question 3

How does Lifitegrast work?

Accepted Answer

Mechanism of Action

Lifitegrast belongs to a class of drugs known as lymphocyte function-associated antigen-1 (LFA-1) antagonists. It works by targeting the underlying inflammation that often contributes to dry eye symptoms.

In dry eye disease, the surface of the eye can become inflamed due to the activity of certain white blood cells. Lifitegrast works by blocking specific protein interactions that drive this inflammatory process. The process involves the following steps:

Binding to LFA-1: Lifitegrast binds to a protein called lymphocyte function-associated antigen-1 (LFA-1) found on the surface of white blood cells (leukocytes).

Blocking ICAM-1 interaction: By binding to LFA-1, the medication prevents it from interacting with another protein called intercellular adhesion molecule-1 (ICAM-1). ICAM-1 is often found in high amounts on the surface of the eye in individuals with dry eye disease.

Reducing inflammation: When these two proteins are prevented from connecting, the inflammatory response on the surface of the eye is decreased.

By reducing this inflammation, lifitegrast helps alleviate the irritation and discomfort associated with dry eye and may help improve the eye's ability to maintain a healthy tear film.

Question 8

What is the dosage of Lifitegrast and how do I take it?

Accepted Answer

How to Use

Lifitegrast is typically applied as one drop into each eye twice a day, approximately 12 hours apart. This medication is provided in single-use containers. To apply the drops correctly, follow these general steps:

Wash your hands thoroughly before handling the medication.

If you wear contact lenses, remove them before using the drops. You should wait at least 15 minutes after application before putting your contact lenses back in.

Tear off one single-use container from the strip and shake it so the liquid moves to the bottom.

Twist off the tab to open the container.

Tilt your head back and pull down the lower eyelid to create a small pocket.

Hold the container over the eye and squeeze one drop into the pocket. Do not let the tip of the container touch your eye, eyelid, fingers, or any other surface.

Repeat the process for the other eye if instructed.

Each single-use container holds enough medicine for both eyes. Discard the container and any remaining liquid immediately after one use. Do not save opened containers for later doses.

Missed Dose

If you miss a dose, use it as soon as you remember. If it is almost time for your next scheduled dose, skip the missed dose and resume your regular schedule. Do not use extra medicine to make up for a missed application.

Question 9

Is Lifitegrast safe during pregnancy and breastfeeding?

Accepted Answer

Pregnancy

It is not known if lifitegrast will harm an unborn baby. There is a lack of adequate data from human studies to confirm its safety during pregnancy. Animal studies using high doses of the medication did not show evidence of harm to the developing fetus. Because the drug is applied topically to the eye, only a small amount enters the bloodstream, which may reduce potential exposure during pregnancy.

Breastfeeding

There is no information available on whether lifitegrast is present in human breast milk or how it might affect a breastfed infant. While the amount of medication absorbed into the body is low, individuals who are breastfeeding should consult with a healthcare professional to weigh the potential benefits against any unknown risks.

Question 10

What forms and strengths does Lifitegrast come in?

Accepted Answer

Available Forms

Lifitegrast is supplied as an ophthalmic solution, which is a liquid intended for use as eye drops. This medication is typically packaged in single-use containers. Each container holds enough liquid to treat both eyes one time.

Strengths

This medication is available in the following strength:

Ophthalmic solution: 5%

The single-use containers are usually provided in foil pouches to protect the medication from light. Once a container is opened, it should be used immediately and then discarded, even if there is liquid remaining.

Question 11

What is the FDA approval status of Lifitegrast?

Accepted Answer

FDA Approval and Indications

Lifitegrast was approved by the U.S. Food and Drug Administration (FDA) in July 2016. It is the first medication in a class of drugs called lymphocyte function-associated antigen-1 (LFA-1) antagonists to receive approval for the treatment of both the signs and symptoms of dry eye disease.

Safety Communications and Monitoring

In 2020, the FDA identified a potential signal of a serious risk regarding reduced visual acuity associated with lifitegrast use, based on reports in the FDA Adverse Event Reporting System (FAERS). Following an evaluation of the available evidence, the FDA determined that no regulatory action or changes to the drug's labeling were required at that time.

There are currently no boxed warnings or Risk Evaluation and Mitigation Strategies (REMS) requirements for lifitegrast. It is available only by prescription and is intended for topical ophthalmic use.

Question 12

What should I know about Lifitegrast and eye drops?

Accepted Answer

Administration Instructions

Lifitegrast is an eye drop solution typically used twice a day, approximately 12 hours apart. It is supplied in individual, single-use containers that are stored inside a foil pouch. It is important to follow specific steps to ensure the medication is used safely and effectively.

Wash your hands thoroughly before using the drops.

Remove one single-use container from the foil pouch.

Tap the container so the solution settles at the bottom.

Twist off the tab to open the container.

Tilt your head back and pull down the lower eyelid to create a small pocket.

Place one drop into the pocket of the eye.

Repeat the process for the other eye if instructed by your doctor.

Important Precautions

To prevent contamination and eye injury, do not let the tip of the container touch your eye, eyelashes, or any other surface. Each container is intended for a single dose in one or both eyes. You must discard the container and any remaining liquid immediately after use; do not save it for a later dose.

If you wear contact lenses, remove them before applying lifitegrast. You should wait at least 15 minutes after using the drops before reinserting your contact lenses. If you are using other eye medications, consult your healthcare provider about the proper timing for each product.
