OK...diving in here...Immunosuppressants drugs are a class of drugs that suppress or reduce, the strength of the body's immune system, aka.. antirejection drugs. transplants etc.
There are divided classes;
(a) Calcineurin inhibitors
(b) Interleukin inhibitors
(c) selective immunosuppressants
(d) TNF alfa inhibitors

Why does Baricitinib an immunosuppressant looking to get re-licensed... warrant/garner a place beside the other (six) MABS.
Azathioprine helps "calm/control" your immune system in inflammatory conditions such as Rheumatoid Arthritis...how is that different from Vyrologix?
