Abstract

These six papers present the effects on human sleep of long-term administration of reserpine (0.50 mg/day), amitriptyline (50 mg/day), chlorpromazine (50 mg/day), chloral hydrate (500 mg/day), and chlordiazepoxide (50 mg/day).

This initial paper describes in detail the methodology of the entire study which involves six 60-day drug periods for each subject completing the protocol-one period on each of the five drugs and one period on placebo, in a balanced design. Measures of laboratory sleep, home sleep, and mood were obtained throughout the study.

Comparisons between the long placebo-only period of this study and the more usual “baseline” period-laboratory nights 4-6-revealed a significantly higher total desynchronized sleep time (D-time) and D-time per cent in the placebo period. Other variables were not significantly different. Some clear changes over time within the long placebo period are also described.
