Oral Inosine Persistently Elevates Plasma antioxidant capacity in Parkinson's disease

ABSTRACT Introduction Higher serum urate predicts slower progression in PD. The aim of this work was to assess whether oral inosine alters antioxidant capacity of plasma or CSF or urinary markers of oxidative injury in early PD. Methods We assayed plasma and CSF antioxidant capacity by ferric‐reducing antioxidant power and measured DNA oxidation adduct 8‐hydroxydeoxyguanosine from urine in Safety of URate Elevation in PD, a randomized, placebo‐controlled trial of oral inosine assessing safety of elevating serum urate from
