Imuran tablets contain a medicine called azathioprine. This belongs to a group of medicines called immunosuppressants.


Even though immunosuppressive agents such as azathioprine (Glax-oSmithKline’s Imuran, generics) and cyclosporine (Novartis’ Sandimmune/Neoral, generics) have been used for decades to treat the signs and symptoms of rheumatoid arthritis, development of novel agents in this class for rheumatoid arthritis has been sluggish because of efficacy and safety concerns that have arisen in clinical trials of agents under development. Nonetheless, companies are pursuing development of immunosuppressive therapies. Immunosuppressants function through a variety of mechanisms, but they generally target key immunologic processes and molecules.
