Summary

National clinical trials, phase II/III, combined in two stages, randomized, double-blind, controlled, parallel, study of superiority, in which three hundred and seven (307) participants of both sexes, aged equal or more than 55 years will be randomly allocated to one of three treatment groups. In the first stage. The group 01 will use Melatonin 3mg plus CBT-I, the group 02 will use Melatonin 5mg plus CBT-I and the group 03 will use CBT-I plus placebo.

Based on the results of an interim analysis will be making a decision on whether to proceed with the study and, if so, on which the doses will be selected for the second stage of the study, to be better studied. The final analysis of the treatments, melatonin in the selected dose plus CBT-I versus CBT-I alone and placebo, will include participants from both stages.

Description

The treatment of insomnia disorder can be accomplished through pharmacological and nonpharmacological approaches. Behavioral techniques of Sleep Hygiene and Stimuli control are the most used. The Sleep hygiene is a psychoeducational intervention that teaches patients to prevent external or environmental factors generate adverse effects and harmful to sleep. The stimulus control technique is based on five instructions that encourages the patient to establish a proper sleep-wake rhythm and strengthens the links between the way for a quick sleep and well established. Melatonin is a hormone that participates in the regulation of the sleep-wake cycle, which is produced and secreted primarily by the pineal gland in the dark period and prepares the individual to sleep. Melatonin is involved in the induction of sleep and has proven therapeutic action in insomnia disorders, and may also play a role in the circadian timing system of mammals and serve as a marker for "biological clock".
