What do imidazoline receptors do?
Conclusion The I1-imidazoline receptor is a specific high-affinity binding site corresponding to a functional cell-surface receptor mediating the antihypertensive actions of moxonidine and other second-generation centrally-acting agents, and may play a role in countering insulin resistance in an animal model of …
What are imidazoline drugs?
Clonidine, an imidazoline, is a selective alpha‐2–adrenergic receptor agonist that is primarily used as a centrally acting antihypertensive agent.
Which receptor is known as imidazoline receptor?
I1 receptor It is found in the neurons of the reticular formation, the dorsomedial medulla oblongata, adrenal medulla, renal epithelium, pancreatic islets, platelets, and the prostate.
What is the example of Antiadrenergic drugs belonging to imidazoline derivative?

| Drug | Target | Type |
|---|---|---|
| Phentolamine | Alpha-1D adrenergic receptor | target |
| Tolazoline | Alpha-1A adrenergic receptor | target |
| Tolazoline | Alpha-2A adrenergic receptor | target |
| Tolazoline | Histamine H1 receptor | target |
Is Moxonidine a beta blocker?
The beta blocker should be stopped first, then moxonidine withdrawn (as above) a few days later, monitoring blood pressure regularly. The manufacturer has not provided clinical data to support this recommendation. Incidence of adverse effects is low, with dry mouth, headache, dizziness and tiredness most common.
What is the structure of imidazoline?
Imidazole is an organic compound with the formula C3N2H4. It is a white or colourless solid that is soluble in water, producing a mildly alkaline solution. In chemistry, it is an aromatic heterocycle, classified as a diazole, and has non-adjacent nitrogen atoms.
Which one of the following is imidazoline derivative?
Clonidine is an imidazoline derivative with α-adrenergic agonist properties; it has been primarily used in the treatment of hypertension. At low doses it appears to stimulate inhibitory, presynaptic adrenergic autoreceptors in the CNS.
Is Tolazoline a imidazoline derivatives?
Tolazoline is a member of the class of imidazoles that is 4,5-dihydro-1H-imidazole substituted by a benzyl group. It has a role as an alpha-adrenergic antagonist, an antihypertensive agent and a vasodilator agent.
Can moxonidine increase blood pressure?
If left untreated, high blood pressure is a risk factor that can increase your chance of developing heart disease, a stroke, and other serious conditions….About moxonidine for high blood pressure.
| Type of medicine | A centrally acting antihypertensive medicine |
|---|---|
| Used for | High blood pressure (hypertension) |
Does moxonidine lower heart rate?
Indeed, in a first study with moxonidine in congestive heart failure, the drug decreased heart rate and plasma norepinephrine levels and performed well in terms of its tolerability. In summary, moxonidine reduces blood pressure mainly through a reduction of MSA in both normotensive and hypertensive subjects.
Is clonidine good for sleep?
Clonidine is approved to treat high blood pressure and ADHD, but there’s not enough data yet to support its use as a treatment for insomnia. While clonidine may cause drowsiness as a side effect, the benefit of this effect doesn’t outweigh the risks of the other side effects.
What is the difference between imidazole and imidazoline?
Imidazoles are used as corrosion inhibitors on specific transition metals, such as copper. Imidazolines are a non-aromatic analog of imidazoles in which one of the double bonds is saturated, and they are non-planar. They further exist in three forms, specifically, 2-imidazolines, 3-imidazolines, and 4-imidazolines.
Which of the following is imidazoline derivative?
Clonidine is an imidazoline derivative used to treat a wide spectrum of clinical disorders.
Can you take moxonidine at night?
If you are asked to take one dose a day, take it in the morning. If you are asked to take two doses a day, take your first dose in the morning and the second dose in the evening. Swallow the tablet whole with a drink of water. You can take moxonidine either before or after a meal.
What are imidazoline receptors?
Imidazoline receptors are the primary receptors on which clonidine and other imidazolines act.
Are hypotensive drugs more selective for imidazolin preferring receptors?
Rilmenidine is the first example of an hypotensive drug more selective for imidazolin preferring receptors than for classical alpha 2-adrenoceptors. Publication types
What is the antagonist of the I 3 receptor?
The only known antagonist for the receptor is idazoxan, which is non-selective. The I 3 receptor regulates insulin secretion from pancreatic beta cells. It may be associated with ATP-sensitive K + (K ATP) channels.
What is an i 2 receptor binding site?
The I 2 receptor binding sites have been defined as being selective binding sites inhibited by the antagonist idazoxan that are not blocked by catecholamines.
