Core tip: Antineutrophil cytoplasmic antibody-associated vasculitis is characterized by a remitting - relapsing course of disease that requires long term immunosuppression. Mycophenolic acid has been evaluated as induction and remission maintenance agent in the treatment of antibody-associated vasculitis as a less toxic agent compared to cyclophosphamide and azathioprine. Mycophenolate has been proven a potent immunosuppressive agent and non-inferior to other available drugs with comparable side effect profile, but several studies have shown a higher relapse rate following discontinuation of mycophenolate or in mycophenolate treated subjects. In this review, the role of mycophenolate in treatment of antibody-associated vasculitis is further discussed.
