ABSTRACT

INTRODUCTION Chronic tinnitus affects 5-15% of the general population; in 1% of individuals with tinnitus this condition severely affects their quality of life. Pharmacological treatment is one of the options for the management of tinnitus patients, but their efficacy remains controversial.

AIM To evaluate the level of evidence to support the use of different drugs in reducing the severity of tinnitus. DEVELOPMENT. The pharmacological groups that have been investigated for the treatment of tinnitus include anesthetics, anticonvulsants, antidepressants, antihistamines, benzodiazepines, diuretics, corticosteroids, and of other substances. Intravenous lidocaine seems to be effective, but the short duration of the effect and the adverse reactions prevent its use. Compared with placebo, carbamazepine and gabapentine have not demonstrated effectiveness although they may be effective in some patients with auditory nerve vascular compression or myoclonus. Tricyclic antidepressants are no more effective than placebo at reducing tinnitus severity although they may improve comorbid depression. There is insufficient evidence to evaluate the effectiveness of selective serotonin reuptake inhibitors and benzodiazepines. Acamprosate may decrease the severity of tinnitus, but the level of evidence is low. There are no consistent results in the studies with intratympanic gentamicin or steroids in tinnitus associated with Ménière’s disease.

CONCLUSIONS The use of pharmacotherapy in reducing the severity of tinnitus is not well supported by prospective, randomized, placebo-controlled clinical trials. Various drugs have been shown to be effective in some studies, but the clinical evidence is limited. Large randomized clinical trials are needed.
