Lifitegrast

Lifitegrast, sold under the brand name Xiidra (/ˈzaɪdrə/[2]), is a medication for the treatment of signs and symptoms of dry eye, a syndrome called keratoconjunctivitis sicca.

[3] It is often used as an alternative to ciclosporin (Ikervis, Restasis, Vevye, Verkazia or Cequa) for dry eye treatment including meibomian gland dysfunction and inflammatory dry eye.

Common side effects in clinical trials were eye irritation, discomfort, blurred vision, and dysgeusia (a distortion of the sense of taste).

Lifitegrast inhibits an integrin, lymphocyte function-associated antigen 1 (LFA-1), from binding to intercellular adhesion molecule 1 (ICAM-1).

[8][9] Lifitegrast was approved by Health Canada in January 2018, and available in Canadian pharmacies as of March 2018.
