Mirabegron is the first clinically available beta-3 agonist with approval for use in adults with overactive bladder. Mirabegron was approved for medical use in the United States and in the European Union in 2012. [8] [9] [3] In 2022, it was the 222nd most commonly prescribed medication in the United States, with more than 1 million prescriptions.
The chemical structure of Solabegron, a β 3-adrenergic receptor agonist. Mirabegron is a selective β 3-AR agonist that affects the detrusor muscles of the urinary bladder.By stimulation of β 3-AR the contraction of the smooth muscles of the bladder is decreased and the bladder can store more volume of urine at a given time.

Vibegron is a selective agonist for the beta-3 adrenergic receptor. The receptors are located in the kidneys, urinary tract and bladder tissue. [20] Upon binding, the β3 receptor undergoes a conformational change. This induces the activation of adenylate cyclases via G proteins and thereby promotes the formation of cyclic adenosine ...
α 2 has 3 subtypes: α 2A, α 2B and α 2C; β receptors are subdivided into β 1, β 2 and β 3. All 3 are coupled to G s proteins, but β 2 and β 3 also couple to G i [7] G i and G s are linked to adenylyl cyclase. Agonist binding thus causes a rise in the intracellular concentration of the second messenger (G i inhibits the production of ...
Beta adrenergic agonists or beta agonists are medications that relax muscles of the airways, causing widening of the airways and resulting in easier breathing. [1] They are a class of sympathomimetic agents, each acting upon the beta adrenoceptors . [ 2 ]
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.
Solabegron (code name GW-427,353) is a drug which acts as a selective agonist for the β 3 adrenergic receptor. It is being developed for the treatment of overactive bladder and irritable bowel syndrome. [1] [2] [3] It has been shown to produce visceral analgesia by releasing somatostatin from adipocytes.
