What is the mechanism of action for clonidine?

Mechanism of Action As an alpha-adrenergic agonist in the nucleus tractus solitarii (NTS), clonidine excites a pathway that inhibits excitatory cardiovascular neurons. Clonidine has an alpha-antagonist effect in the posterior hypothalamus and medulla.

What is the duration of action of clonidine?

The peak action occurs in 10 minutes and lasts for 3-7 hours after single intravenous dose. On oral administration, it reaches a peak plasma level within 60-90 minutes.

Which of the following is the site of action of the drug clonidine?

The data presented in this paper must be considered in conjunction with the fact that clonidine is both a partial alpha-adrenergic agonist and a partial alpha-adrenergic antagonist. In the anterior hypothalamus, clonidine, acting as an alpha-agonist, excites a pathway that inhibits excitatory cardiovascular neurons.

Does clonidine decrease heart rate?

By acting on alpha-agonist hypotensive agents, clonidine decreases heart rate and relaxes blood vessels, which allows blood to flow more freely and better oxygenate body systems. It can also relax the part of the brain that controls impulsivity and attention, which can help children with ADHD symptoms.
