ABSTRACT

BACKGROUND: Pediatric migraine prophylaxis is indicated when headaches are frequent and/or disabling. We aimed to conduct a study to compare the efficacy of cinnarizine and amitriptyline in pediatric migraine prophylaxis. METHODS: In a randomized, double-blind trial, patients aged 4-17 years with migraine who were eligible for prophylaxis enrolled. The primary outcome was a reduction response rate of ≥50% with p < 0.005 with respect to headache characteristics. The secondary outcome was migraine disability assessment. We evaluated patients every four weeks for three months: T1: week 4, T2: week 8 and T3: week 12. The safety profile was also assessed. RESULTS: Thirty patients were randomly assigned to each group. However, 43 patients completed the trial. Headache frequency decreased in amitriptyline group more effectively in T1 (p = 0.004). Amitriptyline was more successful in reducing the headache duration in all three periods (p < 0.005). There was no significant difference in severity improvement and reducing disability score between the two groups (p > 0.005). No serious adverse events were observed. CONCLUSIONS: Both medications are effective in ameliorating migraine headaches and related disabilities. However, amitriptyline appears be a preferable option over cinnarizine, given its faster onset of action, efficacy in reducing headache duration and longer-lasting effects.Trial Registration: The study was registered with the Iranian Registry of Clinical Trials (IRCT) under the code IRCT-20191112045413N1.

ABSTRACT

Acute migraine attacks disrupt performance and reduce the quality of life. Therefore, efforts to prevent these attacks continue using different medications. This study aimed to compare the effect of cinnarizine combination with propranolol and propranolol with placebo in preventing acute migraine attacks. This study was a semi-experimental study performed on 120 adult patients with migraine referred to Department of Neurology in Rezgary Teaching Hospital in Erbil.. Participants were randomly allocated to two groups control (propranolol) and intervention (propranolol with cinnarizine). The frequency, duration and severity of headache attacks were recorded and followed within two months. Data were analyzed with SPSS ver23 software and T-paired, independent T-tests and ANOVA. The average age of the participants was 34.54 years. 60% were female and 55% had a family history of migraine. The average frequency of headache attacks in the intervention group decreased by 75 % (from 15 times to 3 times) and a 50 % decrease in the control group (from 12 times to 6 times). The duration and severity of headaches in both intervention and control groups decreased (p <0.001), respectively. The average frequency, duration and severity of headache attacks in the first- and second months during treatment in the intervention group and control group were statistically different (p <0.001). The drug combination of propranolol with cinnarizine has an additional effect on reducing acute migraine attacks compared to propranolol alone.

ABSTRACT

OBJECTIVE: To investigate and analyze the available data on the prophylactic effectiveness of cinnarizine in migraine disorder. BACKGROUND: Cinnarizine has demonstrated encouraging potential in preventing the attacks of migraine. Therefore, we opted to evaluate whether its sole administration leads to positive outcomes. METHODS: The PubMed, Scopus, Web of Science, and Embase databases were searched for English-only original interventional studies published until April 2022, then screened for relevancy and eligibility. The resulting data from the included studies, including the primary (ie, headache episode frequency, intensity, duration, monthly timing, and analgesic intake frequency) and secondary (ie, reported adverse events, quality of life, and activities of daily living) outcome changes compared to placebo and active controls (e.g., sodium valproate and propranolol) were then recorded by two independent assessors. Ultimately, these data were synthesized qualitatively and quantitatively (achieved by determining the mean difference via the random-effects model). RESULTS: A total of 10 studies comprising seven randomized controlled trials and three quasi-experimental studies were included. Compared to placebo, cinnarizine demonstrated significant improvements in migraine episode frequency (Mean difference = -3.10; Confidence interval = [-3.33, -2.88]; p-value < 0.001; I2  < 0.001%), and intensity (Mean difference = -1.54; Confidence interval = [-2.08, -0.99]; p-value < 0.001; I2  < 37.97%). Moreover, cinnarizine led to similar or better results when compared to active controls, including sodium valproate, topiramate, and propranolol. CONCLUSIONS: Cinnarizine can be considered a safe and effective medication for migraine prophylaxis. However, the relatively small sample size made reaching a definite conclusion impossible. Therefore, a higher number of randomized controlled trials are recommended to be taken place to clarify the situation further.

ABSTRACT

BACKGROUND: Few migraine preventive agents have been assessed in a pediatric population. We evaluated the safety and efficacy of cinnarizine and sodium valproate for migraine prophylaxis in children and adolescents. METHODS: We carried out a randomized double-blind placebo-controlled trial in the Children's Medical Center and Sina hospital, Tehran, Iran. Eligible participants were randomly assigned in 1:1:1 ratio via interactive web response system to receive either cinnarizine, sodium valproate, or placebo. The primary endpoints were the mean change in frequency and intensity of migraine attacks from baseline to the last 4 weeks of trial. The secondary endpoint was the efficacy of each drug in the prevention of migraine. The drug was considered effective if it decreased migraine frequency by more than 50% in the double-blind phase compared with the baseline. Safety endpoint was adverse effects that were reported by children or their parents. RESULTS: A total of 158 children participated. The frequency of migraine attacks significantly reduced compared to baseline in cinnarizine (difference: -8.0; 95% confidence interval (CI): -9.3 to -6.6), sodium valproate (difference: -8.3; 95% confidence interval: -9.3 to -7.2), and placebo (difference: -4.4; 95% confidence interval: -5.4 to -3.4) arms. The decrease was statistically greater in cinnarizine (difference: -3.6; 95% confidence interval: -5.5 to -1.6) and sodium valproate (difference: -3.9; 95% confidence interval: -5.8 to -1.9) arms, compared to placebo group. Children in all groups had significant reduction in intensity of episodes compared to baseline (cinnarizine: -4.6; 95% confidence interval: -5.2 to -4.0; sodium valproate: -4.0; 95% confidence interval: -4.8 to -3.3; placebo: -2.6; 95% confidence interval: -3.4 to -1.8). The decrease was statistically greater in cinnarizine (difference: -2.0; 95% confidence interval: -3.2 to -0.8) and sodium valproate (difference: -1.5; 95% confidence interval: -2.7 to -0.3) arms, compared to the placebo group. Seventy-one percent of individuals in the cinnarizine group, 66% of cases in the sodium valproate group, and 42% of people in the placebo arm reported more than 50% reduction in episodes at the end of the trial. The odds ratio for >50% responder rate was 3.5 (98.3% confidence interval: 1.3 to 9.3) for cinnarizine versus placebo and 2.7 (98.3% confidence interval: 1.0 to 6.9) for sodium valproate versus placebo. Nine individuals reported adverse effects (three in cinnarizine, five in sodium valproate, and one in the placebo group) and one case in the sodium valproate group discontinued the therapy due to severe sedation. CONCLUSION: Cinnarizine and sodium valproate could be useful in migraine prophylaxis in children and adolescents. Trial registration: IRCT201206306907N4.

ABSTRACT

PURPOSE: To compare the efficacy of cinnarizine/betahistine combination with the respective monotherapies in patients with acute peripheral vertigo (APV). METHOD: A randomized, triple-blind placebo-controlled phase III trial was performed on 162 patients with APV to compare the efficacy of cinnarizine/betahistine combination with the respective monotherapies. Patients were randomly allocated into three groups (n = 54 each) of Bet. (betahistine and placebo), Cin. (cinnarizine and placebo), and Bet. + Cin. (betahistine and cinnarizine). The first group received cinnarizine tablets (25 mg) plus placebo three times a day, the second group received betahistine tablets (8 mg) plus placebo three times a day, and the third group received betahistine (8 mg) plus cinnarizine (25 mg) combination three times a day. The treatments were continued for 1 week. Patients were followed up to 3 days and 1 week after initiation of the treatments for changes in vertigo severity measured by visual grading scale (VAS), mean vertigo score (MVS), and mean concomitant symptom score (MCSS). RESULTS: Results showed a significant difference between the groups in VAS (p = 0.001), MVS (p = 0.0001), and MCSS (p = 0.0001) at 1-week follow-up, where the respective values were significantly lower in the Cin. + Bet. group as compared with the respective monotherapies. Efficacy and tolerability of the treatment were found to be higher in the Cin. + Bet. group at 3-day and 1-week follow-up periods (p = 0.0001, for all comparisons). None of the patients reported any side effects during the study. CONCLUSION: This study indicated the superiority of the cinnarizine/betahistine combination over the respective monotherapies in the treatment of APV. TRIAL REGISTRATION: IRCT20130710013947N9.

ABSTRACT

BACKGROUND: When patients suddenly become restless and are unable to sit or stand still, especially in general medical settings, anxiety is often the topmost differential on every clinician's mind. However, the possibility of the very subjectively distressing condition called 'akathisia' should always be considered. OBJECTIVE: The aim of this article is to discuss a clinical approach to the management of akathisia, drawing on the presentation of a patient who was admitted to a general medical ward. DISCUSSION: Akathisia, a subjective and very distressing feeling of restlessness, has been found to be caused by a wide range of medications used in general medical settings, such as azithromycin, antiemetics and antipsychotics. Despite its high incidence and association with an increase in suicidal thoughts, it often goes unrecognised. This paper highlights the need for its early recognition, provides a diagnostic guide and an approach to its management.

ABSTRACT

Vestibular migraine (VM) is one of the most frequent causes of episodic vertigo, with a lifetime prevalence of 0.98%. Prophylactic therapy includes calcium channel blockers, beta-blockers, antiepileptic drugs and antidepressants. We studied the association of cinnarizine 20 mg and dimenhydrinate 40 mg (Arlevertan) in a group of 22 patients affected by definite VM. Proposed therapy included one tablet twice a day for 1 month, which was repeated three times with 1 month of interval between drug intake; results were compared with those of a control group of 11 VM patients who asked to observe only lifestyle measures for migraine. The main outcome was the number of vertigo and headache crises in the 6 months before therapy and in the 6 months of follow-up. Subjects performing Arlevertan presented during the 6 months of therapy a decrease of vertigo attacks from 5.3 to 2.1 and of headaches from 4.3 to 1.7 (p < 0.0001); 68% of these subjects reported a decrease of at least 50% of vertigo attacks, while 63% of headaches. Conversely, vertigo attacks decreased from 3.5 to 2.2 and headaches from 2.6 to 2 in patients observing only lifestyle; 18% of these subjects reported a decrease of at least 50% of vertigo crises and 27% of headaches. Our data do not differ from those of previous works assessing efficacy of different prophylactic therapies for VM and reporting consistent reduction of vertigo spells in a rate of patients ranging from 60 and 80%.

ABSTRACT

AIM: The aim of this randomized, double-blind, parallel-group study was to compare the efficacy and safety of low-dose cinnarizine and sodium valproate in migraine prophylaxis. METHODS: A total of 104 patients were treated during a 12-week treatment period. Cinnarizine dose of 25 mg and 200-mg sodium valproate were administered every 12 hours. During follow-up period, frequency, intensity and duration of migraine attacks, symptoms associated with headache, analgesics use, as well as drugs' side effects were studied. Participants completed Migraine Disability Assessment (MIDAS) and Headache Impact Test (HIT-6) questionnaires before and after treatment. RESULTS: Frequency, intensity and duration of migraine headaches as well as MIDAS score and administration of symptomatic medications decreased significantly between repeated follow-up visits in both groups. Reduction of 4-week migraine frequencies in patients receiving cinnarizine and valproate was 36.4% and 55%, respectively, and the difference between two groups was statistically significant (p < 0.001). CONCLUSION: Our results showed that administration of 25-mg cinnarizine every 12 hours can significantly decrease headache duration (p ≤ 0.001) and headache frequency (p ≤ 0.001) in patients with migraine. These results suggest that cinnarizine may be an appropriate substitution for first-line migraine prophylaxis such as valproate.

ABSTRACT

Flight simulators have an essential role in aircrew training. Occasionally, symptoms of motion sickness, defined as simulator sickness, develop during these sessions. Preventive methods for motion sickness have been investigated thoroughly; however, only a few studies have examined preventive treatments for simulator sickness. The aim of this study was to examine the efficacy of scopolamine (an anticholinergic drug) compared with cinnarizine (an antihistaminic drug) for helicopter simulator sickness prevention. A validated simulator sickness questionnaire (SSQ) score was used to determine the severity of simulator sickness symptoms in this study. Preliminary SSQ scores and SSQ scores after each sortie were calculated. Each participant was given scopolamine, cinnarizine, or a placebo in a double-blind randomized manner before the first sortie of each training day. Forty-one helicopter pilots participated in the trial. The average age was 30.5 ± 7.1 years. SSQ values significantly improved from an average of 73.30 in the preliminary SSQ questionnaire to an average of 30.92 after 2 hours following the administration of cinnarizine (P = .012, 95%CI 8.071-76.703). Scopolamine was found to be less effective than both cinnarizine and the placebo in the alleviation of simulator sickness symptoms. This study is the first to compare scopolamine with cinnarizine for simulator sickness prevention. Based on the results of this study, we recommend the use of cinnarizine over scopolamine for simulator sickness prevention.

ABSTRACT

INTRODUCTION: Meniere's disease is a condition with sudden attacks of vertigo with nausea and vomiting accompanied by loss of hearing and buzzing sensation in the ears, most commonly unilateral. The exact cause of the disease is unknown. Betahistine is the analogue of histamine with weaker agonistic effect on histamine H1 receptors and stronger effect on histamine H3 receptors, while Cinnarizine has more effective effect on H1 receptors. GOAL: The aim is to determine which drug is more effective in the treatment of Meniere's disease Betahistine or Cinnarizine. MATERIAL AND METHODS: This study evaluates the effectiveness of Betahistine in 37 patients with the Meniere's syndrome accompanied by classic triad of symptoms treated in hospital conditions and Cinnarizine effect in 36 patients with a less severe clinical picture, which were treated as outpatients. To all patients were conducted laboratory tests, brain CAT (to exclude possible expansive process, MS or stroke) and TCD in order to eliminate any possible circulatory disturbances in VB basin. Group with classic Meniere's syndrome was treated at a dose of Betahistine of 3 x 16 mg and followed 8 weeks, while the second group was treated with Cinnarizine at a dose of 2 x 75 mg and also followed for 8 weeks. CONCLUSIONS: Already after one month of therapy was noticed better effect in case of Betahistine in terms of symptoms reduction compared to the Cinnarizine effect.

ABSTRACT

To study central genesis of disfunctional menstrual disorders was based particulary on electroencephalography and find out efficacy of pathogenetic management in infertile women with central forms of oligomenorrhoea and amenorrhoea compared to generally accepted hormone therapy. Depending on received management, all 159 patients were divided into two groups. Group I included 93 women with infertility and menstrual disorders treated by taking into account the found cerebral dysfunction. Group II included 66 women received generally accepted hormone therapy. 26 women belonged to group I were found to have regulated menstrual cyclicity (28%) after neuro-mediatorical management with tegretol, finlepsin, cinnarizin, phenazepam,- received during 3-6 months. In group II, in 3 women (4.5%) was obtained improvement and period became regular by using hormone treatment, included Diane-35, Tri-Regol, Marvelon subsequently by generally accepted way during long lasting courses (12 months- more than 1 year). Pregnancy occurred in 17 cases in group I (18.3%). The difference was significantly higher in this group in comparison with group II, where pregnancy was attained only in 3 women (4.5%). Our findings indicate that in the basis of menstrual disorders observed in 159 infertile women were stood dysfunctional changes of central regular mechanisms. Pathogenetic therapy showed that we have taken into consideration neuro-mediatorical correction of found central nervous system level dysfunction. By this way our study reveals significant success of management with neuro-mediatorical purpose compared to the generally accepted hormone therapy.

ABSTRACT

OBJECTIVE: To evaluate the effectiveness and safety of cinnarizine in the treatment of menopausal symptoms. DESIGN: A total of 100 climacteric and symptomatic women participated in a double-blind, placebo-controlled study. They were divided into two groups of the same size: Gcin, intake of 25 mg of cinnarizine every 12 h for 6 months (n=50); and Gpla, placebo intake every 12 hours for 6 months (n=50). Menopausal symptoms were evaluated according to the Kupperman menopausal index on the first visit and at 6 months of treatment. A total of 62 women completed the study: 27 from the Gcin group and 35 from the Gpla group. RESULTS: Based on the Kupperman menopausal index, there were no statistically significant differences between the two groups before and after the treatment. CONCLUSION: Our data suggest cinnarizine is not effective on menopausal symptoms because it had no more efficacy than placebo.

ABSTRACT

Vertigo is not itself a disease, but rather a symptom of various syndromes and disorders that jeopardize balance function, which is essential for daily activities. It is an abnormal sensation of motion that usually occurs in the absence of motion, or when a motion is sensed inaccurately. Due to the complexity of the etiopathogenesis of vertigo, many pharmacological treatments have been tested for efficacy on vertigo. Among these drugs, cinnarizine, usually given together with dimenhydrinate, appears to be the first-line pharmacotherapy for the management of vertigo and inner ear disorders. Based on these considerations, the present non-interventional study aimed to investigate the clinical efficacy and tolerability of a fixed combination of cinnarizine (20 mg) and dimenhydrinate (40 mg) in patients suffering from vertigo-related symptoms. To this end, we enrolled 120 adults-70 males, and 50 females-with an average age of 64 years. Before beginning pharmacological treatment, all patients were screened for the intensity of vertigo, dizziness, and concomitant symptoms through the Visual Scale of Dizziness Disorders and Dizziness Handicap Inventory scales. At the end of the anamnestic evaluation, patients received the fixed-dose combination of cinnarizine (20 mg) plus dimenhydrinate (40 mg) 3 times daily, for 60 days. The results of this study provide further insight regarding the efficacy of the fixed combination when used to reduce symptoms of vestibular vertigo of central and/or peripheral origin, after both the 15- and 60-day therapies. Independent of the type of vertigo, the fixed combination was able to reduce dizziness- and vertigo-associated symptoms in more than 75% of all patients treated, starting from 15 days of therapy, and improving 60 days after starting the therapy. Interestingly, we also found differences between male and female patients in the framework of the pharmacological effects of therapy. This study provides further details concerning the therapeutic efficacy of the fixed combination of cinnarizine and dimenhydrinate, and also focuses attention on the possibility that these drugs could act in a gender-specific manner, paving the way for further research.

ABSTRACT

As an important global disease, cutaneous leishmaniasis is associated with complications such as secondary infections and atrophic scars. The first line treatment with antimonials is expensive and reported to have serious side effects and enhance resistance development. The main objective of this study was to evaluate the effect of Cinnarizine on standard strains of Leishmania major because of paucity of information on this subject. METHODS: In this experimental study, four concentrations of the drug (5, 10, 15 and 20 µg/ml) were added to Leishmania major cultures at 24, 48 and 72 hours intervals. MTT assays were performed to determine parasite viability and drug toxicity. Leishmania major promastigotes were augmented to the in vitro cultured macrophages (J774 cells) and then incubated for 72 hours. Half maximal inhibitory concentration (IC50) was ascertained by counting parasites. The inhibitory effect of the drug was compared with that of Glucantime. Flow-cytometry was performed to investigate apoptosis. Each test was repeated thrice. RESULTS: The IC50 values of Cinnarizine after 72 hours were calculated to be 34.76 µg/ml and 23.73 µg/ml for promastigotes and amastigotes, respectively. The results of MTT assays showed 48 % promastigote viability after 72 hour-exposure to Cinnarizine at 20 µg/ml concentration. Programmed cell death in promastigote- and amastigote-infected macrophages was quantified to be 13.66 % and 98.7 %, respectively. Flow- cytometry analysis indicated that Cinnarizine induced early and late apoptosis in parasites. All treatments produced results which differed significantly from control group (P<0.05). CONCLUSION: Cinnarizine showed low toxicity with anti-leishmanial and apoptosis effects on both promastigote and intracellular amastigote forms. Therefore, we may suggest further assessment on animal models of this drug as candidates for cutaneous leishmaniasis therapy.

ABSTRACT

BACKGROUND AND OBJECTIVE: Vertigo 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. METHODS: In 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. RESULTS: Three 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. CONCLUSION: The 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.

ABSTRACT

BACKGROUND AND OBJECTIVE: Vestibular dysfunction commonly leads to - often severe - vertigo symptoms. The objective of this study was to compare the antivertiginous efficacy and tolerability of a fixed combination of cinnarizine/dimenhydrinate with those of betahistine in patients with acute vertigo due to vestibular disorders. METHODS: Sixty-six patients experiencing acute vertigo attacks participated in this prospective, double-blind, three-centre, comparative study. Patients who assessed at least one vertigo symptom as being of medium intensity (> or =2) on a 5-point visual analogue scale (VAS; from 0 = no symptoms to 4 = very severe symptoms) were randomly allocated to treatment with the fixed combination of cinnarizine 20 mg and dimenhydrinate 40 mg three times daily or betahistine 12 mg three times daily for 4 weeks. The primary efficacy endpoint was change in mean vertigo score, as determined by patients' assessments of 12 individual vertigo symptoms on the 5-point VAS after 4 weeks of treatment. RESULTS: Treatment with the fixed combination led to significantly greater improvements in mean vertigo scores than the reference therapy betahistine after 4 weeks of therapy (p = 0.013). The differences were clinically relevant, based on the Mann-Whitney estimator. Furthermore, the incidence of vertigo-associated vegetative symptoms was significantly reduced after 1 (p = 0.004) and 4 weeks (p = 0.023) in the fixed-combination group relative to the betahistine group. Three patients, all of them in the betahistine group, reported adverse events, none of which was considered serious. Almost all patients (n = 62) rated the tolerabilities of both medications as very good or good. CONCLUSION: The fixed combination of cinnarizine/dimenhydrinate was shown to be an effective and very well tolerated treatment option for patients with acute vertigo due to vestibular disorders. The combination proved to be significantly more efficient in reducing vertigo and associated vegetative symptoms than betahistine in such patients.

ABSTRACT

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.

ABSTRACT

Thirty-seven patients suffering from vertigo associated with vertebrobasilar insufficiency participated in our prospective, single-center, double-blind, comparative study. Patients were randomly allocated to treatment with placebo; betahistine (12 mg betahistine dimesylate, one tablet three times daily); or the fixed combination of 20 mg cinnarizine and 40 mg dimenhydrinate (one tablet three times daily) for 4 weeks. The primary efficacy end point was the decrease of the mean vertigo score (S(M)), which was based on the patients' assessments of 12 individual vertigo symptoms after 4 weeks of treatment. Patients treated with the fixed combination showed significantly greater reductions of S(M) as compared to patients receiving placebo (p < .001) or the reference therapy betahistine (p < .01). The vestibulospinal parameter lateral sway (Unterberger's test) improved to a significantly greater extent in patients taking the fixed combination as compared to those receiving placebo (p < .001). No serious adverse event was reported in any therapy group. The tolerability of the fixed combination was judged as very good or good by 91% (betahistine, 73%; placebo, 82%). In conclusion, the fixed combination proved to be statistically more effective than the common antivertiginous drug betahistine in reducing vertebrobasilar insufficiency-associated vertigo symptoms.
