title: [Sleep changes induced by chronic administration of S. 1694 (Survector) (author's transl)].
abstract: Five adult Macaca mulatta were studied during chronic administration (24 days) of S. 1694 (10 mg/kg, i.m.). This substance induced a significant increase of the first awakening (delaying sleep onset) and an enhancement of the duration of REM and stage 4 sleep. After withdrawal, the waking effect desappeared, but the increase in stage 4 sleep was maintained for one week and REM enhancement kept rising for 15 days. This observation of long-term action underlined the validity of drug experiments in chronic treatment: S. 1694 might set a new type of monoaminergic systems regulation.
