Tinnitus Treatment With Piribedil Guided by Electrocochleography and Acoustic Otoemissions

Abstract

Piribedil is not superior to placebo in the treatment of tinnitus. Piribedil treatment responders differed from nonresponders by specific findings in the ECoG and in the distortion product acoustic otoacoustic emissions, suggesting a beneficial effect of piribedil in an electrophysiologically characterized tinnitus subgroup.
