Agonist vs. antagonist. In pharmacology the term agonist-antagonist or mixed agonist/antagonist is used to refer to a drug which under some conditions behaves as an agonist (a substance that fully activates the receptor that it binds to) while under other conditions, behaves as an antagonist (a substance that binds to a receptor but does not activate and can block the activity of other agonists).
As a result, different GLP-1 agonist drugs are modified in various ways to extend the half-life, resulting in drugs that can be dosed multiple times per day, daily, weekly, or less often. [29] Most synthetic GLP-1 agonists are delivered via subcutaneous injection, which is a barrier to their use and reason for discontinuation. [37]
A co-agonist works with other co-agonists to produce the desired effect together. NMDA receptor activation requires the binding of both glutamate, glycine and D-serine co-agonists. Calcium can also act as a co-agonist at the IP3 receptor. A selective agonist is selective for a specific type of receptor. E.g.
An adrenergic agonist is a drug that stimulates a response from the adrenergic receptors. The five main categories of adrenergic receptors are: α 1, α 2, β 1, β 2, and β 3, although there are more subtypes, and agonists vary in specificity between these receptors, and may be classified respectively. However, there are also other mechanisms ...
Alpha-adrenergic agonists are a class of sympathomimetic agents that selectively stimulates alpha adrenergic receptors. The alpha-adrenergic receptor has two subclasses α 1 and α 2. Alpha 2 receptors are associated with sympatholytic properties. Alpha-adrenergic agonists have the opposite function of alpha blockers.
This allows neuromuscular drugs to act on multiple sites at neuromuscular junctions, mainly as antagonists or agonists of post-junctional nicotinic receptors. [2] Neuromuscular drugs are classified into four main groups, depolarizing neuromuscular blockers, non-depolarizing neuromuscular blockers, acetylcholinesterase inhibitors, and ...
A muscarinic acetylcholine receptor agonist, also simply known as a muscarinic agonist or as a muscarinic agent, is an agent that activates the activity of the muscarinic acetylcholine receptor. [1] The muscarinic receptor has different subtypes, labelled M1-M5, allowing for further differentiation.
Vabicaserin is a full agonist with approximately 4-fold greater selectivity for 5-HT 2C over these related receptors, in terms of binding affinity. Vabicacserin is a full agonist in stimulating the 5-HT 2C receptor; it was discovered when a class of tetrahydroquinoline-fused diazepines were being researched as possible potent 5-HT 2C receptor ...
