Sulodexide Monotherapy in Chronic Idiopathic Subjective Tinnitus: A Randomized Controlled Trial

Abstract

Objective To report the therapeutic value of sulodexide monotherapy in the management of patients with chronic subjective idiopathic tinnitus. Study Design Randomized double-blinded controlled trial. Setting Single tertiary care institution. Subjects and Methods Observations from 124 patients who received either sulodexide or placebo were collected from the patients' medical records. Computer-generated tables were used to allocate treatments. Patients took 1 tablet of the drug or placebo each morning and evening for 40 consecutive days. The response was assessed by the Tinnitus Handicap Inventory and the Mini-Tinnitus Questionnaire. Results Between 2014 and 2017, 124 patients were divided into 2 treatment arms. The sulodexide group encompassed 63 patients, whereas the placebo arm contained 61 patients. Tinnitus Handicap Inventory and Mini-Tinnitus Questionnaire scores were more decreased in the sulodexide arm compared to the placebo group ( P = .03 and P < .01, respectively). Conclusions Sulodexide monotherapy decreases chronic subjective idiopathic tinnitus.
