Indications

Melatonin is used for numerous conditions but is showing the most promise in the short-term regulation of sleep patterns, including jet lag.

Insomnia: Melatonin helps to induce sleep in people with-

Disrupted circadian rhythms (such as those suffering from jet lag or poor vision or those who work the night shift)
Low melatonin levels (such as some elderly and individuals with schizophrenia)
Children with learning disabilities who suffer from insomnia.

Osteoporosis: Melatonin stimulates cells called osteoblasts that promote bone growth.

In Menopause: Melatonin helps peri- or postmenopausal women to regulate sleep patterns.

Eating disorders: Melatonin levels may play a role in the symptoms of anorexia.

Attention Deficit Hyperactivity Disorder (ADHD): it may be effective in managing sleep disturbances in children with this condition. And

Sarcoidosis

Pharmacology

After administration, melatonin binds with its receptors. Two types of melatonin receptor subtypes - MT1 & MT2 have been identified in humans. Melatonin receptors are found in the brain and some peripheral organs. The MT1 subtype is present in the pars tuberalis of the pituitary gland and the suprachiasmatic nuclei of the hypothalamus. The MT2 subtype is mainly present in the retina. Increased level of Melatonin initiates neural & endocrine signals to optimize the levels of neurotransmitters e.g. increased serotonin, increased GABA & decreased dopamine, which induces & sustains sleep, as well as, maintains the body's circadian rhythm.
