Optimizing the pharmacological component of integrated balance therapy.

UNLABELLED: Drug treatment is an important option for the treatment of peripheral vestibular diseases. AIM: To identify the drug component associated with optimal integrated balance therapy (IBT) for Ménières disease or other peripheral vestibular disorders. MATERIALS AND METHODS: Analysis of a series of patients with Ménières disease patients or patients with other peripheral vestibular disorders that received IBT involving either no medication or betahistine, cinnarizine, clonazepam, flunarizine or Ginkgo biloba during 120 days. RESULTS: In Ménières disease, significant differences were observed for all drug therapies (60 days) versus no medication; betahistine was significantly more effective than all other drugs at 60 and 120 days. For non-Ménières disorders, significant differences were observed among betahistine, cinnarizine, clonazepam and flunarizine and no medication after 60 days; all drug therapies were significantly more effective than no medication after 120 days; betahistine, cinnarizine or clonazepam were equally effective and betahistine was more effective than flunarizine and EGb 761. All treatment options were well tolerated. CONCLUSIONS: Drug therapies were more effective than no medication in the IBT for patients with Ménières disease or other peripheral vestibular disorders. Betahistine was the most effective medication for patients with Ménières disease and was as effective as cinnarizine and clonazepam for other peripheral vestibular disorders.

Clonazepam in the pharmacological treatment of vertigo and tinnitus.

We carried out a retrospective survey of 25 years of clinical experience with the use of clonazepam as a vestibular and tinnitus suppressant in the pharmacological treatment of vestibular or cochleovestibular disorders due to different causes. We reviewed the medical records of 3,357 outpatients treated with a 0.5 or 1.0-mg daily dosage of oral clonazepam during 60-180 days. Complete or substantial control of vertigo or nonvertiginous dizziness was achieved in 77.4% of the vertigo patients. Tinnitus was improved in 32.0% of the tinnitus patients. Light or mild drowsiness, depression, nightmares, or lowering of libido, reported by 16.9% of the patients as adverse side effects, tended to subside with continued therapy. We concluded that clonazepam is a very useful and safe drug for the symptomatic treatment of patients suffering from cochleovestibular disorders.
