If they are also known as alpha-adrenergic blocking drugs (i'm not sure if they are), then they prevent norepinephrine from producing sympathetic responses.

What are dopamine receptor antagonists?
Dopamine receptor antagonists (DAs)-- The older class of antipsychotic medications, also called neuroleptics. These primarily block the site on nerve cells that normally receive the brain chemical dopamine.
Does trazodone increase dopamine?
If trazodone does impact dopamine, it does so very slightly, and such effect is negligible. So, I would say no. Trazodone is an agonist for the 5-HT (serotonin)-1A receptor (similar to buspirone, where it acts to reduce anxiety). It also antagonizes (blocks) the following receptor subtypes: - 5-HT 2A, 2B, and 2C - alpha-1 and alpha-2 adrenergic receptors - histamine-1 receptor
What does an OH group at position 3 and 4 of the benzene ring of adrenergic drugs result in?
It results in maximal alpha and beta receptor activity.
Relationship between agonist and antagonist?
We mostly talk about agonists and antagonists with regards to cellular receptors. An agonist binds to a receptor and activates it, an antagonist binds to the receptor, but DOES NOT activate it, and prevents it from being activated.
Which receives signals a fluid mosaic model or a receptor?
a receptor
What are the effects of dopamine receptor antagonists?
They inhibit the expression of dopamine.

Is diltiazem an anticholinergic?
No, it's a muscarinic receptor antagonist. Yes, it belongs to class of anticholineric compounds known as muscarinic receptor antagonists.
Is mycardis an alpha blocker?
No, Mycardis is not an alpha blocker, it is a receptor blocker.
Is telmisartan an alpha blocker?
No, Telmisartan is not an alpha blocker, it is a receptor blocker.
Are LSD and other hallucinogenic drugs antagonists?
Depending on the hallucinogen, it may be either an agonist or an antagonist at certain receptors. Classic psychedelics such as LSD and psilocybin are 5-HT2A receptor agonists, whereas dissociatives (PCP, DXM, ketamine, etc.) are NMDA receptor antagonists. Deliriants, such as atropine and scopolamine, are muscarinic antagonists.
What does ketamine and pcp do to your body?
No, although similar in the fact that they are both NDMA receptor antagonists, PCP(Phencyclidine) is a completely different chemical then ketamine. No, although similar in the fact that they are both NDMA receptor antagonists, PCP(Phencyclidine) is a completely different chemical then ketamine.
Can gastritis be cured?
Simple gastritis can be cured by a course of PPI e.g. omeprazole or H2 receptor antagonists e.g. ranitidine.
What is the mechanism of medication for somebody who is diagnosed with gastric ulcers and antihistamine drug was prescribed to him?
Histamine Type-2 Receptor Antagonists (H2 Blockers)
Is Zantac a Proton Pump Inhibitor?
Zantac is H2 receptor antagonist, not a proton pump inhibitor. The H2 receptor antagonists are a class of drugs used to block the action of histamine on parietal cells in the stomach, decreasing the production of acid by these cells.
What group does Ketamine belong to?
Ketamine is in a group of medications known as N-methyl d-aspartate (NMDA) receptor antagonists, and is legally used as an anesthetic for humans and animals.
Name 3h-2 antagonist?
If you mean to name three drugs that work as histamine-2 receptor antagonists, they are Cimetidine, Ranitidine and Famotidine. hope I understood your question correctly.
