Vibegron is a selective beta 3 adrenergic receptor (β3AR) agonist that is being developed in Japan jointly by Kyorin Pharmaceutical Co., Ltd and Kissei Pharmaceutical Co., Ltd and in other regions worldwide (except in several other Asian countries) by Urovant Sciences for the treatment of overactive bladder (OAB). Vibegron potently activates human b3AR and increases cAMP levels, with an EC50 of 1.1 nM. Based on results from Japanese phase III trials, vibegron received approval in Japan in September 2018 for this indication. Vibegron, an active ingredient of Beova® Tablets, is a novel once-daily oral treatment for overactive bladder (OAB), acts selectively on the bladder's β3-adrenergic receptor, relaxes the bladder and enhances the urine collection, and consequently improves the symptoms of urgency, urinary frequency and urge urinary incontinence associated with OAB. On December 23, 2020 the FDA approved vibegron (Gemtesa) for the treatment of adult patients with overactive bladder (OAB) with symptoms of urge urinary incontinence (UUI), urgency, and urinary frequency.

Mirabegron (trade name Myrbetriq in the US and Betmiga in Europe) is a drug for the treatment of overactive bladder (OAB). It was developed by Astellas Pharma and was approved in the United States in July 2012. Originally developed as a treatment for diabetes, the development of mirabegron was later refocused to OAB. Mirabegron is an orally bioavailable agonist of the human beta-3 adrenergic receptor (ADRB3), with muscle relaxing, neuroprotective and potential antineoplastic activities. Upon oral administration, mirabegron binds to and activates ADRB3, which leads to smooth muscle relaxation. Mirabegron also restores sympathetic stimulation in mesenchymal stem cell (MSC) niches, inhibits JAK2-mutated hematopoietic stem cell (HSC) expansion and blocks the progression of myeloproliferative neoplasms (MPNs). Lack of sympathetic stimulation of the MSC and HSC niche is associated with the development of MPNs.

Isoproterenol (trade names Medihaler-Iso and Isuprel) is a medication used for the treatment of bradycardia (slow heart rate), heart block, and rarely for asthma. Isoproterenol is a non-selective β adrenoreceptor agonist and TAAR1 agonist that is the isopropylaminomethyl analog of epinephrine. Isoprenaline's effects on the cardiovascular system (non-selective) relate to its actions on cardiac β1 receptors and β2 receptors on smooth muscle within the tunica media of arterioles. Isoprenaline has positive inotropic and chronotropic effects on the heart. β2 adrenoceptor stimulation in arteriolar smooth muscle induces vasodilation. Its inotropic and chronotropic effects elevate systolic blood pressure, while its vasodilatory effects tend to lower diastolic blood pressure. The overall effect is to decrease mean arterial pressure due to the β2 receptors' vasodilation. The adverse effects of isoprenaline are also related to the drug's cardiovascular effects. Isoprenaline can produce tachycardia (an elevated heart rate), which predisposes patients to cardiac arrhythmias.

Amibegron (SR 58611A or SR 58611) is a highly selective agonist for atypical beta3-adrenoceptors. It stimulates neuronal activity in a specific area of the prefrontal cortex and also inhibits intestinal motility. Amibegron was in phase III trials worldwide for the treatment of depression and generalised anxiety disorder but development of the product was discontinued in 2008. Amibegron has been tested for its potential as a treatment for irritable bowel syndrome.

Talibegron (ZD2079) is a β3 adrenoceptor agonist and insulin sensitiser. It was developed as a potential treatment for obesity and non-insulin-dependent diabetes mellitus. Talibegron hydrochloride had been in phase II clinical trials by AstraZeneca for the treatment of type 2 diabetes and obesity. However, this research has been discontinued.

LY377604 is a human β3-adrenergic receptor agonist and β1- and β2-adrenergic receptor antagonist with no sympathomimetic activity at the β1- and β2-adrenergic receptors. Combination of LY377604 and a norepinephrine-serotonin uptake inhibitor (sibutramine) was studied in the treatment of obesity. LY377604 would ameliorate side effect of sibutramine treatment (increase in blood pressure and heart rate due to activation of the sympathetic nervous system).

Mantabegron is an adamantane derivative with β3-adrenoreceptor agonist activity.

Cimaterol is a chemically stable nonselective agonist β1-, β2-, and β3-adrenoceptors. Cimaterol is used in sport as a stimulant and a fat burner that assists bodybuilders and strength athletes to get rid of body fats. Aside from shedding off fats, another benefit for using cimaterol for athletes is a boost in strength as well as an increase in muscle size or lean body mass. The increase in muscle size has been seen in previous animal studies when cimaterol is used. However, the reason behind the muscle gain is not identified yet, but the body has a very different response compared from taking in anabolic steroids. Experts in the field are saying that the increased nitrogen retention, that is known to cause by cimaterol, maybe the reason behind the muscle gain. Another great thing about Cimaterol is that, it can improve blood flow.
