BACKGROUND AND OBJECTIVEVertigo derived from peripheral vestibular disorders is quite frequently encountered in daily clinical practice and can be a severely disabling symptom associated with substantial impairment of health-related quality of life for the affected patients. Betahistine, a structural analogue of histamine and presumably the most widely prescribed anti-vertigo drug worldwide, has previously been shown to be an effective and safe treatment for these patients. The objective of the present study was to evaluate whether the fixed combination of cinnarizine and dimenhydrinate (Arlevert^®) is non-inferior and thus a potentially useful alternative to betahistine dihydrochloride in the treatment of patients suffering from peripheral vestibular vertigo.METHODSIn this prospective, multicenter, double-blind, randomized, non-inferiority clinical trial, outpatients from 8 ENT clinics in Austria, Bulgaria, the Czech Republic and Russia were randomly assigned to receive three times daily one tablet of either the fixed combination cinnarizine 20 mg/dimenhydrinate 40 mg or betahistine dihydrochloride 16 mg for 4 weeks. Primary endpoint was the reduction of the mean vertigo score (MVS), a validated 12-item composite score defined as the mean of 6 vertigo symptoms (dystasia and walking unsteadiness, staggering, rotary sensation, tendency to fall, lift sensation, blackout) and 6 trigger factors for vertigo (change of position, bowing, getting up, driving by car/train, head movements, eye movement), after 4 weeks of therapy, as judged by the patient on a 5-point visual analogue scale (VAS). The non-inferiority margin was set to 0.3. Secondary outcomes included the patient's and investigator's judgment of global efficacy, the patient's rating of impairment of daily activities, and safety/tolerability of the treatments.RESULTSThree hundred and six patients (mean age 53.5 years, approximately 60% female) were enrolled and randomized to the fixed combination cinnarizine/dimenhydrinate (n = 152) or betahistine (n = 154) groups; 297 patients completed the study and 294 (146 and 148, respectively) were valid for the per-protocol analysis, which was used for the non-inferiority analysis. Treatment with cinnarizine/dimenhydrinate led to a stronger reduction of the MVS [least squares mean (LSM)] after 4-week therapy (primary endpoint) in comparison to betahistine (0.395 vs 0.488; difference: - 0.093, 95% CI - 0.180; - 0.007, p = 0.035); since the upper limit of the two-sided 95% confidence interval was not only below the non-inferiority margin of 0.3, but also entirely below 0, superiority of the fixed combination could be demonstrated. The combination preparation was also more effective after 1 week of therapy and received more favorable patient's ratings on overall efficacy and impairment of daily activities. Both treatments were very well tolerated. Only 12 patients (3.92%) reported 13 non-serious adverse events; 2 cinnarizine/dimenhydrinate-treated patients discontinued the study prematurely due to adverse events as compared to 5 betahistine-treated patients.CONCLUSIONThe fixed combination of cinnarizine 20 mg and dimenhydrinate 40 mg was found to be not only non-inferior, but superior to betahistine 16 mg in the improvement of peripheral vestibular vertigo. Furthermore, taking into account a good and slightly favorable safety profile, the present study provides evidence that the fixed-combination preparation is a potent and even superior alternative to betahistine in the treatment of vertigo related to peripheral vestibular disorders.STUDY REGISTRATIONEudraCT No. 2011-004025-27.

From 2001 to 2006, we performed a retrospective study of patients suffering from chronic unilateral or bilateral tinnitus that was previously ineffectively treated by oral drugs [betahistine (Betaserc), extract of Ginkgo biloba (EGb 761), tanakan (Tebokan), and cinnarizine-dimenhydrinate (Arlevert), singly or in combination]. We divided 150 tinnitus patients (80 men, 70 women) into seven treatment groups. Treatments consisted of application of intravenous pentoxifylline, lidocaine, or vinpocetine (Cavinton) and combination of these agents with physiotherapy and soft laser. Mean duration (+/- standard deviation) of tinnitus in these patients was 7.4 +/- 6.0 years; their mean age was 55.6 +/- 12.5 years. The aim of our study was to compare treatment modalities and define their effectiveness for tinnitus relief. The most effective treatment was defined as a combination of Cavinton and physiotherapy. We evaluated pure lidocaine infusion therapy as ineffective. None of the treatment modalities had an objective correlate of improvement, though improvement was reported by a visual analog scale.

Fixed combination of cinnarizine and dimenhydrinate versus betahistine dimesylate in the treatment of Ménière's disease: a randomized, double-blind, parallel group clinical study.

In a randomized, double-blind clinical study, we evaluated the efficacy and tolerability of the fixed combination of cinnarizine, 20 mg, and dimenhydrinate, 40 mg (Arlevert [ARL]) in comparison to betahistine dimesylate (12 mg) in 82 patients suffering from Ménière's disease for at least 3 months and showing the characteristic triad of symptoms (paroxysmal vertigo attacks, cochlear hearing loss, and tinnitus). The treatment (one tablet three times daily) extended to 12 weeks, with control visits at 1, 3, 6, and 12 weeks after drug intake. The study demonstrated for both the fixed-combination ARL and for betahistine a highly efficient reduction of vertigo symptoms in the course of the 12 weeks of treatment; however, no statistically significant difference between the two treatment groups could be established. Similar results were found for tinnitus (approximately 60% reduction) and for the associated vegetative symptoms (almost complete disappearance). Vestibulospinal reactions, recorded by means of craniocorpography, also improved distinctly, with a statistically significant superiority of ARL versus betahistine (p < .042) for the parameter of lateral sway (Unterberger's test). The caloric tests (electronystagmography) showed only minor changes for both treatment groups in the course of the study. A statistically significant improvement of hearing function of the affected ear (p = .042) was found for the combination preparation after 12 weeks of treatment. The tolerability was judged by the vast majority of patients (97.5%) in both groups to be very good. Only one patient (betahistine group) reported a nonserious adverse event, and two betahistine patients did not complete the study. In conclusion, the combination preparation proved to be a highly efficient and safe treatment option for Ménière's disease and may be used both in the management of acute episodes and in long-term treatment. Efficacy and safety were found to be similar to the widely used standard therapy with betahistine.
