H sub 2 sub histamine receptors, found principally in the parietal ...A histamine antagonist , commonly referred to as antihistamine , is a pharmaceutical drug that inhibits action of histamine by blocking it from attaching to histamine receptor s. Clinical effects Histamine s produce increased vascular permeability, causing fluid to escape from capillaries into tissues, which leads to the classic symptoms of an allergic reaction a runny nose and watery eyes. Antihistamines suppress the histamine induced Wheal response wheal swelling and vasodilation flare response by blocking the binding of histamine to its receptors on nerves, vascular smooth muscle, glandular cells, endothelium, and mast cells. They effectively exert competitive antagonism of histamine for H1 receptors. Itching and sneezing are suppressed by antihistamine blockade of H1 receptors on nasal sensory nerves. ref Monroe, E., MD, Daly, A., and Shalhoub, R., MD. 1997.

Sufficient antagonist will displace the agonist from the binding sites, resulting in a lower frequency of receptor activation.

About the type of muscle other uses Antagonist Unreferenced date December 2009 Most muscles work in pairs, and when a muscle works it needs to have an Agonist muscle agonist and an antagonist , unless the muscle s natural state is opposite to that which is produced by the muscle, example Sphincter ani externus muscle . An antagonist is a classification used to describe a muscle that acts in opposition to the specific movement generated by the Agonist muscle agonist and is responsible for returning a limb to its initial position. Antagonistic pairs Antagonistic muscles are found in pairs called antagonistic pairs. These consist of an extensor muscle , which opens the joint i.e. increasing the angle between the two bones , flexor muscle , which does the opposite to an extensor muscle . Antagonistic pairs are needed in the body because muscles can only exert a pulling force, and can t push themselves back into their original positions. An example of this kind of muscle pairing is the biceps brachii and triceps brachii . When the biceps brachii biceps are contracting, the triceps are relaxed, and stretches back to its original position. The opposite happens when the triceps contract.

A serotonin antagonist is a drug used to inhibit the action at serotonin receptor s. Many of the most important medications of this class selectively act at the 5 HT3 receptor , and thus are known as 5 HT3 antagonist s. However, other drugs such as ketanserin act upon other types of serotonin receptors. Antagonists of the 5 HT2A 5 HT sub 2A sub receptor are sometimes used as atypical antipsychotic s, with the typical antipsychotic s being purely dopamine antagonist s. Ketanserine blocks 5 HT2A,5 HT2C and alpha 1 receptors. Ondansetron,Dolansetron,Granisetron are 5 HT3 receptor antagonist.they are efficacious in treating chemotherapy induced emesis. Clozapine blocks 5 HT2A,5 HT2C,D4 receptors. Quetiapine blocks 5 HT2A,5 HT1A,D1 2,HI,alpha 1 receptors. Methsergide is 5 HT2A 2C antagonist and nonselective 5 HT 1 receptor blocker.it causes retrperitoneal fibrosis and mediastinal fibrosis.

An opioid antagonist is a receptor antagonist that acts on opioid receptor s. Naloxone and naltrexone are commonly used opioid antagonist drugs which are competitive antagonist s that bind to the opioid receptors with higher affinity than agonists but do not activate the receptors. This effectively blocks the receptor, preventing the body from responding to opiates and endorphins. Some opioid antagonists are not pure antagonists but in fact do produce some weak opioid partial agonist effects, and can produce analgesic effects when administered in high doses to opioid naive individuals. Examples of such compounds include nalorphine and levallorphan . However the analgesic effects from these drugs are limited and tend to be accompanied by dysphoria , most likely due to action at the kappa opioid receptor . As they induce opioid withdrawal effects in people who are taking, or have recently used, opioid full agonists, these drugs are considered to be antagonists for practical purposes. The weak partial agonist effect can be useful for some purposes, and has previously been used for purposes such as long term maintenance of former opioid addicts using nalorphine, however it can also have disadvantages such as worsening respiratory depression in patients who have overdosed on non opioid sedatives such as Alcoholic beverage alcohol or barbiturates . Naloxone on the other hand has no partial agonist effects, and is in fact a partial inverse agonist at mu opioid receptors, and so is the preferred ...
