The optimal amount, or quantity of sleep varies from individual to individual.
However, there is poor correlation between quantity of sleep, as measured by e.g. electrodes in sleep labs, and quality of sleep, as perceived by the patient.
In contrast to other sleep drugs, quality of sleep, as evaluated by validated questionnaires, has been the primary endpoint when developing Circadin. By doing this the patient is in focus: it is the personal experience of the refreshing outcome of their sleep, which is prioritised.
Circadin is fulfilling the unmet needs of insomniacs in good sleep and improves quality of life.
