Ginkgo biloba Administered Singly and Combined With Antioxidants in Tinnitus Patients

Abstract

Background and Objectives: Tinnitus, or ear ringing, involves impulsive and spontaneous activity in the auditory neurons. Its prevalence is high in the elderly, but 10%–15% of adults suffer from tinnitus, affecting their quality of life. Therefore, this study aimed to evaluate the efficacy of Ginkgo biloba administered singly and in combination with antioxidants in tinnitus patients. Subjects and Methods: Patients were randomly allocated to Placebo (T0, n=22), Treatment 1 (T1, n=24), and Treatment 2 (T2, n=23) groups. The patients were educated on the study’s methodology and were instructed to visit at 0, 4, 8, 12, and 14 weeks. The placebo group received starch capsule supplements. Conversely, the treatment groups received Ginkgo biloba (60 mg twice a day) singly and in combination with antioxidants. We enrolled 69 patients aged 40–70 years (41 men, 28 women). The Tinnitus Handicap Index (THI), Visual Analogue Score (VAS), and Short Form 36 (SF-36) Health Scores were determined pre and post-treatment at each visit. Results: Supplementation of Ginkgo biloba, along with antioxidants, provided marked improvement (p<0.05) in post-treatment THI and VAS scores in the T2 group compared to those in the T1 and T0 groups. The greatest (p<0.05) percent difference was observed in the pre and post-treatment THI (-36%) and VAS scores (-22.6%) of T2 patients. Likewise, the SF-36 scores improved significantly (p<0.05) in the T2 group in varied parameters. Conclusions: Ginkgo biloba, along with antioxidants, can be a promising therapy for tinnitus patients, providing marked improvement in THI, VAS, and SF-36 scores.
