Treatment of primary systemic vasculitis with the inosine monophosphate dehydrogenase inhibitor mycophenolic acid.

Despite advances in the treatment of vasculitis, modern therapies fail to induce or maintain remission in a significant proportion of patients. Mycophenolic acid is increasingly used to treat vasculitis syndromes. Here, we consider relevant pharmacokinetic and pharmacodynamic properties of mycophenolate, with emphasis on the impact of renal impairment, and we review the existing evidence for and current trials of mycophenolate in the treatment of primary systemic vasculitides.
