Janus kinase (JAK) inhibitor
LuciRux is a brand name for Ruxolitinib tablets, which are used to treat certain blood disorders and graft-versus-host disease. Ruxolitinib is a JAK inhibitor, meaning it works by blocking certain enzymes (JAK1 and JAK2) that play a role in the overproduction of blood cells and inflammation. LuciRux is available in 5mg and 20mg tablet strengths and is typically taken orally, with or without food, once or twice daily.
