The chemical name for lifitegrast is (S)-2-(2-(benzofuran-6-carbonyl)-5,7-dichloro-1,2,3,4-tetrahydroisoquinoline-6-carboxamido)-3-(3-(methylsulfonyl)phenyl)propanoic acid. The molecular formula of lifitegrast is C 29 H 24 Cl 2 N 2 O 7 S and its molecular weight is 615.5 g/mol. The structural formula of lifitegrast is: *Chiral center Lifitegrast is a white to off-white powder, which is practically insoluble in water. Lifitegrast ophthalmic solution 5% is a lymphocyte function-associated antigen-1 (LFA­-1) antagonist supplied as a sterile, clear, colorless to slightly brownish-yellow colored, isotonic solution of lifitegrast with a pH of 7.0 to 8.0 and an osmolality range of 200 to 330 mOsmol/kg. Lifitegrast ophthalmic solution contains Active: lifitegrast 50 mg/mL; Inactives: sodium chloride, dibasic sodium phosphate anhydrous, sodium thiosulfate pentahydrate, sodium hydroxide and/or hydrochloric acid (to adjust pH) and water for injection.

AND USAGE Xiidra ® (lifitegrast ophthalmic solution) 5% is indicated for the treatment of the signs and symptoms of dry eye disease (DED). Xiidra (lifitegrast ophthalmic solution) 5% is a lymphocyte function-associated antigen-1 (LFA-1) antagonist indicated for the treatment of the signs and symptoms of dry eye disease (DED). ( 1 )

AND ADMINISTRATION Instill one drop of lifitegrast ophthalmic solution twice daily (approximately 12 hours apart) into each eye using a single-dose container. Discard the single-dose container immediately after using in each eye. Contact lenses should be removed prior to the administration of lifitegrast ophthalmic solution and may be reinserted 15 minutes following administration. One drop twice daily in each eye (approximately 12 hours apart).

Xiidra is contraindicated in patients with known hypersensitivity to lifitegrast or to any of the other ingredients in the formulation [see Adverse Reactions (6.2) ]. Hypersensitivity. ( 4 )

REACTIONS The following serious adverse reactions are described elsewhere in the labeling:

• Hypersensitivity [see Contraindications (4) ] The most common adverse reactions (incidence 5% to 25%) following the use of lifitegrast were instillation-site irritation, dysgeusia and decreased visual acuity.

6.1 Clinical Trials Experience Because clinical trials are conducted under widely varying conditions, adverse reaction rates observed in clinical trials of a drug cannot be directly compared to rates in the clinical trials of another drug and may not reflect the rates observed in practice. In five clinical trials of DED conducted with lifitegrast ophthalmic solution, 1401 patients received at least one dose of lifitegrast (1287 of which received lifitegrast 5%). The majority of patients (84%) had less than or equal to 3 months of treatment exposure. One hundred-seventy patients were exposed to lifitegrast for approximately 12 months. The majority of the treated patients were female (77%). The most common adverse reactions reported in 5% to 25% of patients were instillation-site irritation, dysgeusia, and reduced visual acuity. Other adverse reactions reported in 1% to 5% of the patients were blurred vision, conjunctival hyperemia, eye irritation, headache, increased lacrimation, eye discharge, eye discomfort, eye pruritus, and sinusitis.

6.2 Postmarketing Experience The following adverse reactions have been identified during post-approval use of lifitegrast. Because these reactions are reported voluntarily from a population of uncertain size, it is not always possible to reliably estimate their frequency or establish a causal relationship to drug exposure. Rare serious cases of hypersensitivity, including anaphylactic reaction, bronchospasm, respiratory distress, pharyngeal edema, swollen tongue, urticaria, allergic conjunctivitis, dyspnea, angioedema, and allergic dermatitis have been reported. Eye swelling and rash have also been reported <span class="opacity-50 text-xs">[see Contraindications (4) ]</span>.
