Sulpiride combined with hydroxyzine significantly reduced tinnitus perception in patients. This combination therapy offers a promising new avenue for managing tinnitus symptoms.

Area of Science:

  • Otorhinolaryngology
  • Neuropharmacology

Background:

  • Subjective tinnitus is a prevalent condition impacting quality of life.
  • The auditolimbic dopaminergic pathway is implicated in tinnitus perception.

Purpose of the Study:

  • To evaluate the efficacy of sulpiride and hydroxyzine in managing subjective tinnitus.
  • To assess the combined effect of a D2 antagonist and a subcortical sedative on tinnitus perception.

Main Methods:

  • A prospective, randomized, single-blind, placebo-controlled study involving 150 patients with subjective tinnitus.
  • Patients were assigned to three groups: sulpiride alone, sulpiride plus hydroxyzine, or placebo, for one month.
  • Tinnitus perception was evaluated using the Subjective Grading of Tinnitus Perception and a visual analogical scale.

Main Results:

  • Tinnitus perception decreased by 56% with sulpiride alone and 81% with sulpiride plus hydroxyzine.
  • Visual analog scale scores for tinnitus intensity reduced from 7.8 to 6.3 (sulpiride) and 7.8 to 5.1 (sulpiride plus hydroxyzine).

Conclusions:

  • The combination of sulpiride and hydroxyzine effectively decreases tinnitus perception.
  • Targeting the tinnitus auditolimbic dopaminergic pathway presents significant therapeutic potential.
