Double blind, placebo-controlled randomized clinical trial to evaluate the efficacy and safety of a transtympanic treatment of tinnitus with caroverine

Caroverine infusions have been used successfully in Austria to treat cochlear-synaptic tinnitus. This treatment is very time consuming and needs a constant monitoring of the physician. This study will investigate the efficacy and safety of caroverine eardrops for transtympanic treatment of tinnitus. The aim is to ascertain whether the results of the proof of concept study using a 1,5 % solution can be reproduced.
