Psoriasis is a complex, chronic, multifactorial, inflammatory disease that involves hyperproliferation of the keratinocytes in the epidermis, with an increase in the epidermal cell turnover rate (see the image below).
Clonidine, an alpha 2 -adrenergic agonist, is believed to act through regulation of norepinephrine release from the locus ceruleus. It has been found to be effective in reducing ADHD symptoms alone or in combination with stimulants.
Clonidine may be used to ease withdrawal symptoms associated with the long-term use of narcotics, alcohol, benzodiazepines and nicotine (smoking). It can alleviate opioid withdrawal symptoms by reducing the sympathetic nervous system response such as tachycardia and hypertension, as well as reducing sweating, hot and cold flashes, and general restlessness.
