L04: Immunosuppressants
ATC L04 immunosuppressants: the level-2 group covering L04A, from calcineurin inhibitors to the interleukin and JAK inhibitors.
L04 has a single level-3 subgroup, L04A, which carries the whole group: calcineurin inhibitors (ciclosporin, tacrolimus), TNF-α inhibitors, interleukin inhibitors, and the JAK inhibitors. WHO gives L04 and L04A the same name.
