Descrizione riassuntiva dello studio

The study aims to verify whether the medication Safinamide (Xadago®) is capable of improving sleep quality and other non-motor symptoms in patients with moderate to advanced Parkinson's disease who exhibit sleep disturbances and show a fluctuating response to levodopa therapy, thus transitioning from periods of relative well-being (ON) to phases of greater "motor block" (OFF). In patients with Parkinson's disease, there is an alteration in the functioning of certain brain regions involved in the production and release of a substance called dopamine, which thus becomes "lacking". Xadago® is a medication that can block the degradation of dopamine, increasing its amount in the brain and thereby improving the patient's motor symptoms (referred to as dopaminergic effect). Additionally, Xadago® also acts through other mechanisms (regulation of sodium and glutamate channels) and may improve sleep and other non-motor symptoms (referred to as non-dopaminergic effect).

(BASEC)

Intervento studiato

Xadago® is administered according to the approval. Treatment begins at a dose of 50 mg per day for 2 weeks, after which the dose will be increased to 100 mg per day for 10 weeks.
