ABSTRACT
Melatonin, the major regulator of the sleep/wake cycle, also plays important physiological and pharmacological roles in the control of neuronal plasticity and neuroprotection. Accordingly, the secretion of this hormone reaches the maximal extent during brain development (childhood-adolescence) while it is greatly reduced during aging, a condition associated to altered sleep pattern and reduced neuronal plasticity. Altogether, these properties of melatonin have allowed us to demonstrate in both experimental models and clinical studies the great chronobiotic efficacy and sleep promoting effects of exogenous melatonin. Thus, the prolonged release formulation of melatonin, present as a drug in the pharmaceutical market, has been recently recommended for the treatment of insomnia in over 55 years old subjects.
ABSTRACT
Insomnia symptoms might affect about 60% of the Italian population. Insomnia is a "24 hours syndrome" and a risk factor for medical and mental disorders. It should always be assessed and treated in the clinical practice. Cognitive Behavioral Therapy for Insomnia is the first line treatment but its availability in Italy is scarce. Pharmacological options in Italy are: melatonin 2 mg prolonged release that should be the first choice in subjects ≥55 years old and used until 13 weeks; and for a short term use (≤4 weeks) Z-drugs or short-acting benzodiazepines (in subjects <65 years old) or a sedating antidepressant.
