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.
