Tolonidine is a prescription medicine used to treat high blood pressure. It is a centrally acting α2-adrenergic agonist, which means it works by reducing nerve signals in the brain that can lead to high blood pressure. It may be used alone or in combination with other medicines. Side effects of tolonidine include drowsiness, dizziness, dry mouth, and constipation.
Tolonidine is a medication that was investigated as a potential treatment for high blood pressure (hypertension). It belongs to a class of drugs called imidazoline receptor agonists, which work by stimulating certain receptors in the body that help to lower blood pressure. Unfortunately, tolonidine was never widely marketed and is not currently available as a prescription medication.
Here's a breakdown of what we know about Tolonidine:
- Chemical Classification: Tolonidine is an organic compound belonging to the class of aniline and substituted anilines [1].
- Mechanism of Action: Tolonidine works as an imidazoline receptor agonist, similar to other medications like moxonidine and rilmenidine [2]. Imidazoline receptors are found in the brainstem and throughout the body and play a role in regulating blood pressure. By activating these receptors, tolonidine helps to decrease blood pressure.
- Effects: Studies in animals showed that tolonidine was effective in lowering blood pressure. It achieved this by reducing the force of heart contractions, decreasing blood flow, and increasing peripheral vascular resistance (resistance to blood flow in the vessels farthest from the heart) [4, 5].
While tolonidine showed promise as a potential treatment for hypertension, it was never widely marketed and is not currently available as a prescription medication. There is no information available about the reasons for this.
