Real-world use of Safinamide in motor fluctuating Parkinson's disease patients in Italy.

Introduction: Safinamide is a recent antiparkinsonian drug that modulates both dopaminergic and glutamatergic systems with positive effects on motor and nonmotor symptoms of Parkinson's disease (PD). Here, we aimed to describe the efficacy and safety of safinamide in the Italian PD patients in real-life conditions.

Methods: We performed a sub-analysis of the Italian cohort of the SYNAPSES study, a multi-country, multi-center, retrospective-prospective cohort observational study, designed to investigate the use of safinamide in routine clinical practice.

Variation in the dopaminergic response during the day in Parkinson disease.

Objective: In many parkinsonian patients with fluctuating disease the early morning levodopa dose is more effective than the following dose on the same day. In this study we investigated whether the poor responsiveness to the early afternoon dose of levodopa depends only on peripheral and central levodopa pharmacokinetics or also on pharmacodynamic factors.

Methods: Ten parkinsonian patients experiencing postprandial drug-resistant off periods received two boluses of apomorphine by subcutaneous injection at 8 am and 3 pm on two nonconsecutive days.

Apomorphine infusion and the long-duration response to levodopa in advanced Parkinson's disease.

The authors investigated the long-duration response to levodopa in advanced Parkinson's disease. Eight patients with advanced Parkinson's disease disabled by severe ON/OFF fluctuations treated by chronic daytime subcutaneous apomorphine infusion with supplemental oral levodopa were studied. On day 1, oral levodopa was withdrawn at 4:00 pm and on the following morning subcutaneous apomorphine infusion was continued at the same rate without levodopa therapy.
