Melatonin is a natural brain hormone that appears to be involved in setting biologic rhythms. It may induce sleepiness in some individuals and can be helpful in adjusting biologic rhythms (e.g., help with sleep cycles in individuals with severe visual impairment). Short-acting (primarily to help with sleep onset) and long-acting preparations (to help with sleep maintenance) are marketed. While melatonin is "natural," little has been investigated about potential side effects associated with long-term use. In addition, since sold as a natural supplement, the FDA does not regulate manufacturing of this compound, leading to potential for variation in quality within, and across, preparations. Some suggest that this preparation may also lose effectiveness when used chronically. Research in pediatrics is limited, but suggests that melatonin may be useful in select situations (e.g., severe visual impairment, autism and other neurodevelopmental disabilities, phase shifts). Clonidine belongs to a class of drugs called central alpha-adrenergic agonists. In the United States, clonidine tablets are sold under the brand name Catapres and clonidine skin patches are sold under the brand name Catapres-TTS. There is also an injectable form that is administered directly into the spinal cord for the treatment of postoperative pain. Clonidine tablets and patches are approved by the United States Food and Drug Administration (FDA) for the treatment of high blood pressure. However, clonidine has been found to be useful in the treatment of alcohol, opiate, and nicotine withdrawal syndromes, attention-deficit/hyperactivity disorder (ADHD), and Tourette's syndrome, one of the tic disorders . Clonidine was synthesized in 1960s and was initially tested as a nasal decongestant. In the United States, clonidine was first used to treat hypertension although it has also been investigated for treatment of different neuropsychiatric disorders. Clonidine works on specific nerve cells in the brain that are responsible for lowering blood pressure, slowing heart rate, and decreasing the body's reaction to the withdrawal of chemicals like alcohol, opiates, cocaine, and nicotine.
