Melatonin is a hormone found naturally in the body but is made synthetically in a laboratory for supplemental purposes. Melatonin is typically used for the inability to fall asleep (insomnia); delayed sleep phase syndrome (DSPS); insomnia associated with attention deficit-hyperactivity disorder (ADHD); insomnia due to certain high blood pressure medications called beta-blockers; and sleep problems in children with developmental disorders including autism and cerebral palsy.

Melatonin (N-acetyl-5-methoxytryptamine) is a neurohormone that is primarily produced by the pineal gland, located behind the third ventricle in the brain. In the synthesis of melatonin, tryptophan is hydroxylated to 5-hydroxytryptophan, which in turn is decarboxylated to 5-hydroxytryptamine (serotonin). Serotonin is converted to the melatonin precursor and metabolite Nacetylserotonin by the enzyme N-acetyl transferase. N-acetylserotonin is methylated via the enzyme hydroxyindole-o-methyltransferase to produce melatonin. Approximately 90 percent of melatonin is cleared in a single passage through the liver. A small proportion of unmetabolized melatonin is also excreted in the urine.
