Melatonin is a chronohypnotic that decreases firing rate of neurons in SCN via MT1 receptor, but only when endogenous levels are low (i.e. daytime). In older adults, the amount of MT synthesized and the number and affinity of MT1 receptors all decrease. Does not make you feel drowsy. It enhances natural sleep wake cycle. Must be paired with good sleep hygiene. Only need very small amounts (1 mg). Give 1 hr before bedtime. The body makes 1 mg per day, at higher doses exogenous melatonin might decrease your body's ability to synthesize it on its own. Higher doses in the short term show a dose dependent effect, but this wears off quickly and then melatonin stops working at all.

Melatonin is a chronohypnotic that is secreted by the pineal gland and decreases firing rate of neurons in SCN via MT1 receptor. Normal peak serum concentrations are 60 pg/ml. Less than 1 mg is synthesized per day. In older adults, the amount of MT synthesized and the number and affinity of MT1 receptors all decrease. Does not make you feel drowsy. It enhances natural sleep wake cycle. Must be paired with good sleep hygiene. Only need very small amounts (1 mg). Give 1 hr before bedtime.

Melatonin

Melatonin is a chronohypnotic that is secreted by the pineal gland and decreases firing rate of neurons in SCN via MT1 receptor. Normal peak serum concentrations are 60 pg/ml. Less than 1 mg is synthesized per day. In older adults, the amount of MT synthesized and the number and affinity of MT1 receptors all decrease. Does not make you feel drowsy. It enhances natural sleep wake cycle. Must be paired with good sleep hygiene. Only need very small amounts (1 mg). Give 1 hr before bedtime. The body makes 1 mg per day, at higher doses exogenous melatonin might decrease your body's ability to synthesize it on its own. Higher doses in the short term show a dose dependent effect, but this wears off quickly and then melatonin stops working at all.

    • Double-blind, placebo-controlled study, subjects who slept normally (n = 15) or were insomniacs, i.e. exhibited actigraphically confirmed decreases in sleep efficiency (n = 15) received, in randomized order, a placebo and three melatonin doses (0.1, 0.3, and 3.0 mg) orally 30 min before bedtime for a week. There was a non-dose dependent increase in sleep efficiency in insomniacs but not in controls. The 3 mg dose caused transient hypothermia and supraphysiologic plasma melatonin levels that persisted for much of the following day.

    • In a meta analysis of 17 randomized, double-blind, placebo controlled studies with objective sleep eval including 284 patients, melatonin decreased sleep latency by 2-5 minutes, improved sleep efficiency by 2-3%, and increased sleep length by 13 min. Melatonin doses ranged from 0.1 to 80 mg PO, or 50 mg IV in one study.

    • Meta analysis of 16 studies (9 RCTs), in patients aged 55-73 receiving oral melatonin in doses ranging from 0.1 to 50 mg/kg. Melatonin at higher doses led to a prolonged supraphysiologic plasma concentration, with some studies showing that this decreased the effectiveness of melatonin compared to lower doses.
