RESUMO

OBJECTIVES: This pre-clinical study was performed to assess the effects of ethaverine in the two kinds of behavioral models of depression in rats. METHODS: We observed the changes of the immobility time in the forced swimming test and the quantity of sucrose consumed in the chronic mild stress model, using ethaverine(20mg/kg) alone, imipramine(20mg/kg) alone, or ethaverine and imipramine concomitantly. RESULTS: In the forced swimming test, both single treatment and chronic treatment(for 7 days) with imipramine or ethaverine significantly reduced the immobility time, and concomitant chronic treatment with ethaverine potentiated the effect of imipramine. In the chronic mild stress model, both imipramine and ethaverine reversed the decreased sucrose consumption induced by 3-week stress and concomitantly treated ethaverine potentiated the effect of imipramine in the early phase of treatment. CONCLUSIONS: The data suggest that ethaverine can be used alone or concomitantly with other anti-depressants in the clinical situation.

RESUMO

Although many drugs are currently available in the treatment of vascular dementia, there are no licensed drugs for it with proven efficacy. The major treatment efforts are therefore focused on the management of the underlying causes and control of risk factors. Antiplatelet agents or anticoagulants such as a low dose of aspirin or warfarin should be used in all patients where there is no contraindication. Hypertension should be properly controlled not to make the patient hypotensive. Blood cholesterol and triglyceride, especially LDL cholesterol, should be assessed and, if raised, treated using diet or drugs. And if the patient is diabetic, it should be controlled also. If the patient is a smoker, they should be encouraged to stop smoking. Supportive measures such as gait retraining, prophylaxis against limb contractures, and speech therapy are indicated in selected patients. Pathophysiological processes common to both vascular dementia and dementia of Alzheimer's type may include microglial activation, increased production of cytokines, free radicals and glutamate. Propentofylline, a neuroprotective glial cell modulator, has been shown to be effective in the management of the patients with Alzheimer's disease or vascular dementia. Other therapies such as estrogen, non-steroid anti-inflammatory drugs and anti-oxidants such as vitamin E/selegiline (MAO-B inhibitor), Gingko biloba are sometimes used and show promise in delaying the progression of dementia. But several further clinical trials are needed to determine whether these new therapies can be successfully used in patients with vascular dementia or dementia of Alzheimer's type.
