The World Health Organization's ATC classification organizes medical drugs based on therapeutic properties, chemical composition, and anatomy. It helps make essential medicines readily available globally and is widely used in the pharmaceutical industry.

| Etrasimod |
Etrasimod is a sphingosine-1-phosphate (S1P) receptor modulator that binds to S1P receptors 1, 4 and 5 (S1P1,4,5) and is a balanced G-protein and beta-arrestin agonist at S1P1. Etrasimod has minimal activity on S1P3 and no activity on S1P2. Etrasimod partially and reversibly blocks the capacity of lymphocytes to egress from lymphoid organs, reducing the number of lymphocytes in peripheral blood thereby lowering the number of activated lymphocytes in the tissue. The mechanism by which etrasimod exerts therapeutic effects in ulcerative colitis is unknown but may involve the reduction of lymphocyte migration into sites of inflammation. |
