Antagonist drugs bind to the receptors in the brain and block the binding of opioids to the receptors thereby inhibiting the effect of the opioid. All rights reserved. The list of inverse antagonist drugs includes: Depending on the mechanism used for triggering a biological response, we can distinguish the following antagonists: When the drug causes an effect that blocks the formation of another chemical molecule, it has the properties of a chemical antagonist. Several angiotensin II receptor blockers are available. . H2 antagonists block histamine-induced gastric acid secretion from the parietal cells of the gastric mucosa (lining of the stomach). Whereas an antagonist is a drug that binds to the receptor either on the primary site, or on another site, which all together stops the receptor from producing a response. They have been implemented in the therapy administered to patients suffering from psychiatric diseases, such as anxiety, insomnia, depression, etc. Similar electrophysiological effects also occur at the atrioventricular AV node.

Strong doses can have many side effects related to respiration, organ failure, drowsiness, and numbness. There are mixed agonists/antagonists, which demonstrate varying activity depending on the opioid receptor but also varying on the dose. Another class of medications called long-acting beta-agonists (LABAs for short) is more commonly used in treating severe asthma. A partial agonist also binds to a receptor but only partially activates it. An agonist is a drug that binds to the receptor, producing a similar response to the intended chemical and receptor.
