General description
1,7-Dimethyluric acid is an important metabolite of caffeine.[1] Electrochemical oxidation of 1,7-dimethyluric acid was studied over a wide pH range of 2.2-10.3 at solid electrodes.
Application
1,7-Dimethyluric acid is the suitable reagent used for the simultaneous determination of plasma levels of theophylline and its metabolites without interference from caffeine or caffeine metabolites by HPLC.[1]

Omeprazole has previously been shown to induce hepatic cytochrome P4501A2 activity, as evidenced by an accelerated N-3-demethylation in the 13C-[N-3-methyl]-caffeine breath test. In this study we investigated whether the inducing potency of omeprazole can be quantified by the determination of
