This study analyzed the macrostructure and microstructure of sleep in 12 parkinsonian patients under basal conditions (T0) and during 1-night treatment (T1) with a new formulation of apomorphine. This new formulation consisted in a microemulsion of apomorphine administered by the transdermal route, able to provide a constant release of the drug over several hours (APO-TD). Sleep analysis at T1 compared with T0 revealed a 16% increment of total sleep time, a 12% increment of sleep efficiency, a 16% increment of stage 3 and 4 non-REM sleep, a 15% reduction of periodic limb movements index, a 22% reduction of arousal index, and a 23% reduction of cycling alternating patterns/non-REM. We conclude that APO-TD may be able to reduce nocturnal anomalous movements, akinesia, and rigidity in Parkinson's disease, and may reduce the disturbed sleep typical of Parkinson's disease.
