5-amino salicylic acid with an antibacterial drug for RA
Sulfasalazine
Other uses for sulfasalazine
UC and Crohn’s
Drug that suppresses T cell responses to mitogens, reduces chemotaxis and phagocytosis of polymorphonuclear leukocytes, and decreases the production of superoxide radicals

Recombinant human IL-1 receptor antagonist
Anakinra
Action of IL-1 in RA
