Brief summary

This is a French national trial, conducted using a double-blind, placebo-controlled, randomised design involving 15 centers and 88 patients of both sexes. The primary objective of the trial is to evaluate the effect of a selective inhibitor of serotonin reuptake, the Fluoxétine, at a higher dose (40 mg/day) than usually recommended for depressed patients, after three months in patients suffering from an atypical Parkinson's disease called Multiple System Atrophy, compared to the placebo effect. Secondary objectives of the trial are the evaluation of the effects of Fluoxétine after six weeks at the dose of 20 mg/day, after six months at the dose of 40mg/day, and assess the effects on mortality, quality of life, autonomic disorders, particularly orthostatic hypotension, mood and others symptoms such as sleep, apathy, pain and fatigue.

Detailed description

Fluoxetine is first introduced in dose of 20 mg/day and after six weeks the dose is increased to 40 mg/day. If patients have side effects at the dose of 40 mg/day, the dose may be reduced at 20 mg/day. Assessment visits will be conducted at 6 weeks, 3 months, and 6 months of treatment. After 6 months, trial's treatment with fluoxetine is discontinued gradually. A new assessment will be conducted one month after the end of treatment. The expected results are the demonstration of improved scores of the scale UMSARS after 3 and 6 months in the fluoxetine group compared to the placebo group.

Exclusion criteria

* Patient presenting major swallowing problems as he will not take capsule * Patient already receiving a selective inhibitor of serotonin reuptake or other antidepressant, or patient having received one in the 3 months preceding the start of the study * Patient with major depressive syndrome for which the investigator considers that the indication of an antidepressant seems essential * Bedridden patient or confined to a wheelchair during the whole day * Patient with severe hyponatremia * Patient with another Parkinsonian's syndrome that the Multiple System Atrophy (type of atypical Parkinson's disease, progressive supra nuclear paralysis, cortico-basal degeneration) * Patient with dementia * Patient with a Mini-Mental State Exam score \< 24 * Patient unable to understand the protocol or another endpoint or to consider the clinical trial's process * Patient with a chronic disease affecting the development or assessment of the patient during the trial * Patient receiving concomitant medications which could affect the evaluation of outcome measures (e.g. neuroleptics for the assessment of parkinsonian symptoms, vasodilators for the assessment of orthostatic hypotension, sedative drugs prescribed during the day for the assessment of the daytime sleepiness, of apathy or of fatigue) * Patient with absolute or relative contraindications of Fluoxetine (hypersensitivity to Fluoxetine, patient with a history of epilepsy, of manic state, of severe hepatic or renal impairment, of skin bleeding, of severe heart, of uncontrolled diabete, patient treated by selective or non selective IMAO) * Person who are: wards of the state or prisoners (requirement under french law) * Patient pregnant or at risk of same, nursing mother
