In a controlled double-blind study, 78 patients with moderate senile dementia were randomly assigned to 3-months' treatment with 200 mg naftidrofuryl twice daily in slow-release form or with placebo. The patients were selected on the basis of the EACG (Echelle d'Appréciation Clinique en Gériatrie), which was also used as main criterion for confirmatory analysis of the efficacy of naftidrofuryl. A further main criterion was the SGRS (Stockton Geriatric Rating Scale). Secondary criteria examined were visual memory as tested in the Benton test, verbal memory as tested in the Rey test and numerical memory as tested in the digit-span test. The patients' concentration was tested in the Zazzo test. The tests were performed before the patients were admitted to the study and after 1 and 3-months' treatment. Confirmatory analysis of the primary criteria showed a significant treatment difference in favour of naftidrofuryl in the form of improvement in the global symptoms of senile dementia both in the EACG and in the SGRS, the scores in the naftidrofuryl group improving by 15% compared with only 5% in the placebo group. This was paralleled by a significant improvement in visual and verbal memory in the naftidrofuryl group in comparison with placebo. The naftidrofuryl patients also showed a greater improvement in concentration than the placebo group. One patient in the naftidrofuryl group suffered briefly from gastro-intestinal symptoms. There were no changes in routine laboratory parameters studied. Dementia is a cerebral disorder resulting in a progressive deterioration of intellectual function that compromises the patient's ability to function. The diagnostic criteria for dementia are primarily clinical and are based on the Diagnostic and Statistical Manual of Mental Disorders, Fourth Edition. The Hachinski score and computed tomography of the brain help distinguish between degenerative and vascular dementias.
                This study examined the efficacy of naftidrofuryl in patients with vascular or mixed dementia.
                This multicenter, randomized, double-blind study compared naftidrofuryl 600 mg/d with placebo for 1 year in patients with vascular or mixed dementia. A preliminary 2-month washout period allowed selection of patients who were compliant with treatment. The end point was change in the scores on the Alzheimer Disease Assessment Scale cognitive subscale and the Mini-Mental State Examination.
                Eighty-four patients were assessable on an intent-to-treat basis, and 74 were assessable for the per-protocol analysis (on-treatment). Statistically significant improvements in cognitive and global function were observed in patients receiving naftidrofuryl. Naftidrofuryl was well tolerated, and produced no clinically significant abnormalities in laboratory test results.
                The results of this study suggest that naftidrofuryl is effective and well tolerated in treating the symptoms of vascular and mixed dementia. The design of this study was based on the European guidelines for the treatment of Alzheimer's disease. After a placebo run-in period of 4 weeks, patients with a diagnosis of vascular dementia (VaD) were randomised to receive either 400 mg naftidrofuryl/day, 600 mg naftidrofuryl/day or placebo for 6 months. The patients were assessed using the ADAS-cog, the SCAG, the NOSGER and the CGI item 2 scale. The primary analysis was undertaken on the ITT population. At the end of the study, significantly more patients in the treatment groups showed no deterioration on both ADAS-cog and SCAG scales compared with placebo (400 mg p = 0.005, 600mg p = 0.015). There were also significant differences between the active and placebo groups for the individual scales. This study has demonstrated that treatment with naftidrofuryl can slow the rate of deterioration of patients with vascular dementia. nan nan There is evidence to support the use of naftidrofuryl in acute stroke with claims of increased recovery, reduced fatality and reduced bed occupancy in patients treated with either oral or intravenous preparations. One hundred patients presenting with acute hemisphere stroke (less than 72 hours) were randomized to receive either a new oral formulation of naftidrofuryl or placebo on a double-blind basis. Treatment was given for a total of 12 weeks and patients followed for 26 weeks with serial neurological and functional assessments by a single observer. Cumulative fatality and hospital-bed occupancy were determined at each assessment interval. No significant difference was demonstrated in cumulative fatality, hospital-bed occupancy or recovery of motor function in patients treated with either naftidrofuryl or placebo. There is no evidence from this study to support the use of oral naftidrofuryl in acute stroke. This study was conducted to compare an automated test of paced stimulus material (Sperling's Perceptual Trace, SPT) with several other standard memory scales. Sixty patients with mild senile organic brain syndrome were divided into two groups of 30; one group was treated for 90 days with 300 mg daily of naftidrofuryl (Praxilene), and the other group received placebo. The patients were tested before treatment and at 30, 60 and 90 days after the beginning of treatment. The data indicated that the SPT indirectly assesses short-term memory, is resistant to practice effects, and is drug-sensitive. It is suggested that the SPT might become the test of choice in the indirect assessment of short-term memory in the elderly. The efficacy of naftidrofuryl ( Dusodril ) for treatment of stage II arterial occlusive disease was evaluated in a controlled multi-centre study in a total of 104 out-patients with angiographically documented localization of occlusion. The therapeutic effect was assessed over three months by measurements of walking distance using standardized treadmill conditions. Further parameters were venoocclusive plethysmography and Doppler ultrasonography measurement of pressures. The complaint-free walking distance increased significantly during daily application of 600 mg naftidrofuryl orally (n = 54) during the 12-week assessment period when compared to the placebo group (n = 50). Taking the intraindividual variability of 17.2 m in assessment of walking distance into account, the increase of painless walking of 93 m after treatment for 12 weeks in the active-drug group is considered the result of treatment-induced increased performance. The effect of Naftidrofuryl (Nafronyl) on the symptoms of severe peripheral vascular disease has been studied in 40 hospital inpatients. Assessment of ischaemic symptoms and of symptoms which may occur with any type of chronic pain was made using a linear analogue system. Patients treated with naftidrofuryl showed a significant symptomatic improvement compared to patients treated without vasoactive drug therapy. These results show that this drug has a useful place in the treatment of severe ischaemic symptoms during assessment for vascular reconstruction and in those patients found to be unsuitable for limb-salvage operations.
Oral administration of naftidrofuryl is well-tolerated by patients with dementia.The low-quality evidence shows that, by use of naftidrofuryl, people with dementia may benefit on performance, behaviour, cognition, and mood. However, the benefit on global impression is inconsistent and unconvincing.
