title: [Effect of piribedil on nocturnal sleep (author's transl)].
abstract: Piribedil, a dopamine agonist, was administered to 5 normal male subjects for two weeks. During the first two nights there was a reduction of about 17 p. 100 in paradoxical sleep (PS) and an increase of about 13 p. 100 in slow sleep II. There was a 15 p. 100 increase in PS during the third night. This increase is maintained for 8 nights in 3 subjects and 13 nights in 2 subjects. Other sleep parameters were not altered. Piribedil appears to give the impression of satisfactory sleep by reducing the subjective period before falling asleep. Piribedil also diminishes the remembrance of dreams.
