Definition and Uses

Clonidine is a medication that belongs to the class of centrally acting alpha-2 adrenergic agonists. It is commonly used to treat conditions such as high blood pressure, ADHD (Attention Deficit Hyperactivity Disorder), anxiety, and withdrawal symptoms from alcohol and opioid dependence.


Clonidine acts on the alpha-2 receptors in the brain, which are responsible for reducing sympathetic outflow from the central nervous system. By stimulating these receptors, clonidine helps to decrease the activity of certain neurotransmitters, resulting in a decrease in blood pressure and a calming effect on the body.

Condition Utilization
High Blood Pressure Clonidine is used as a primary or adjunctive treatment for hypertension.
ADHD Clonidine can be prescribed to children and adults to help manage symptoms of ADHD.
Anxiety Clonidine may be used off-label to alleviate anxiety symptoms in certain cases.
Substance Withdrawal Clonidine is sometimes utilized to relieve withdrawal symptoms associated with alcohol or opioid dependence.

Mechanism of Action

Clonidine exerts its effects by stimulating alpha-adrenergic receptors in the brain, leading to a decrease in the release of norepinephrine, a neurotransmitter that plays a key role in regulating blood pressure and heart rate. By reducing the sympathetic outflow from the central nervous system, clonidine helps to lower blood pressure and relieve symptoms of conditions such as hypertension and ADHD.
