What are the side effects of Mirabegron?
One study showed that the adverse effects of mirabegron include hypertension (most commonly), nasopharyngitis, and urinary tract infection.[6] Dry mouth (a common side effect of the anti-muscarinics) is six-fold less in mirabegron because mirabegron does not affect the muscarinic receptors in the salivary glands.[6] Other side effects include tachycardia, constipation, headache, back pain, dizziness, palpitations, atrial fibrillation, urticarial reaction, joint pain, and joint swelling.[7] Mirabegron is considered a very safe and effective drug. Mirabegron may also be more useful in the elderly population as the neurocognitive concerns of anti-muscarinic therapy may not be as much of a problem; however, this requires further investigation.
How fast does mirabegron work?
Mirabegron is absorbed fairly quickly after oral administration, with maximum plasma concentration achieved in roughly 3 hours. The liver’s CYP450 system predominantly metabolizes mirabegron. Monitoring and dose adjustment should take place with patients on other medications with a narrow therapeutic index, and that also undergo metabolism via CYP2D6.[7] According to American Family Physicians (AAFP), potent inhibitors of the CYP2D6 system are amiodarone, cimetidine, diphenhydramine, fluoxetine, paroxetine, quinidine, ritonavir, and terbinafine. Substrates of the CYP2D6 system are amitriptyline, carvedilol, codeine, donepezil, haloperidol, metoprolol, paroxetine, risperidone, and tramadol. There are no significant inducers. In this light, it is vital to consider all comorbidities and drugs that patients are on to prevent undesirable drug-drug interactions. It is recommended to take a thorough history, with consideration of past medical history and review of medications before starting mirabegron therapy.
Is Mirabegron a once daily drug?
Mirabegron is a once-daily orally administered drug.[3] It is available in 25 mg or 50 mg strengths. The lower strength tablet is recommended as a starting dose and for patients with severe renal or moderate hepatic impairment, and the higher dose tablet is recommended for patients to take with or without food if they tolerate the lower dose.[3] Other therapeutic routes of administration (intravenous, rectal, enteral, epidural, intracerebral, etc.) for mirabegron are not FDA approved in the treatment of OAB. Mirabegron may take 4 to 8 weeks before patients see improvements in their symptoms.
Is Mirabegron a sympathomimetic?

Is mirabegron safe for dogs?
Mirabegron has been shown to have a very broad safety level in humans. Caution is advisable with drugs that exert effects on or are metabolized by the liver, as mirabegron is also hepatically metabolized. Though safe in humans, studies have shown toxicity in dogs in the form of tachycardia and erythema. [10]

Who conducted the Mirabegron study?
The research, which was conducted by Blayne Welk, MD, MSc, and Eric McArthur, MSc, both of Western University in London, Ontario, Canada, compared matched cohorts of patients who were newly prescribed an anticholinergic agent or mirabegron for OAB.
Which anticholinergic is the most commonly used?
Tolterodine, including both immediate-release and long-acting formulations, was the most commonly used anticholinergic agent (40%) followed by oxybutynin (29%) and solifenacin (26%). In an exploratory analysis, the risk of dementia did not vary between the different anticholinergics.
Is OAB a beta 3 agonist?
Patients using anticholinergic medications for the management of overactive bladder (OAB) are at increased risk of new-onset dementia compared with individuals treated with the beta-3 agonist mirabegron (Myrbetriq), according to findings of a new population-based, retrospective study published online March 13, 2020, in BJU International.
What is Mirabegron?
Mirabegron is a β 3 -adrenoreceptor agonist that represents an alternative OAB treatment to antimuscarinics, and potentially has a more favorable benefit-to-risk ratio in older patient populations [ 20, 21, 22, 23 ].
How many patients were randomized to Mirabegron?
Of the 2380 patients screened, 445 were randomized to mirabegron and 443 to placebo; one patient in the placebo group did not receive treatment (Table 1 ). Of the 887 randomized patients who received ≥1 dose of study drug, overall 72.3% were female, 79.5% were white, and 28.1% were aged ≥75 years. In total, 226 patients received mirabegron 25 mg and only 219/445 patients (49.2%) uptitrated to 50 mg. There were no meaningful differences in demographic characteristics at baseline between the total mirabegron group and the placebo group. All patients had ≥1 comorbidity and 94.3% were receiving ≥1 concomitant medication; those relevant to cognition are shown in Table 2. One third of patients in the SAF had a history of psychiatric disorders, the most common being depression (17.2%), insomnia (15.7%), and anxiety (11.4%). Charlson Comorbidity Index scores (mean ± SD) were low: 2.3 ± 1.2 for both groups (Table 1 ).
What is the treatment for OAB?
Antimuscarinics are often used for treatment of overactive bladder (OAB), but exposure to medications such as antimuscarinics that have anticholinergic properties has been linked to adverse cognitive effects. A phase 4 placebo-controlled study (PILLAR; NCT02216214) described the efficacy and safety of mirabegron, a β 3 -adrenoreceptor agonist, for treatment of wet OAB in patients aged ≥65 years. This pre-planned analysis aimed to measure differences in cognitive function between mirabegron and placebo, using a rapid screening instrument for mild cognitive impairment: the Montreal Cognitive Assessment (MoCA).
Can antimuscarinics be used for OAB?
Antimuscarinics are used to treat OAB, however, the risk of anticholinergic adverse events (AEs) such as dry mouth and constipation increases with age [ 12 ] . Exposure to medications with anticholinergic properties has also been linked to adverse cognitive effects, in particular in patients ≥65 years [ 13 ]. Furthermore, older people are particularly sensitive to anticholinergic effects as a result of significant age-related decrease in cholinergic neurons/receptors in the brain, reduction in hepatic and renal clearance of medications, and increase in blood-brain barrier (BBB) permeability [ 14 ]. In addition, the older patient population is likely to be receiving polypharmacy including other drugs with anticholinergic activity (e.g. tricyclic antidepressants, bronchodilators, ACE inhibitors, and antipsychotics), potentially resulting in a problematic anticholinergic burden, with negative effects on cognitive performance [ 15 ]. As a result, the Beers criteria lists all antimuscarinic drugs used for the treatment of OAB as potentially inappropriate for first-line treatment in those ≥65 years of age with dementia or cognitive impairment [ 16 ].
Why are older people more sensitive to anticholinergics?
Furthermore, older people are particularly sensitive to anticholinergic effects as a result of significant age-related decrease in cholinergic neurons/receptors in the brain, reduction in hepatic and renal clearance of medications, and increase in blood-brain barrier (BBB) permeability [ 14 ].
Is Springer Nature neutral?
Springer Nature remains neutral with regard to jurisdictional claims in published maps and institutional affiliations.
Does Mirabegron affect cognition?
Together with the efficacy demonstrated during the PILLAR study, these data suggest that mirabegron does not worsen cognition in older adults treated for OAB who are at risk of or concerned about cognitive impairment. Therefore, mirabegron represents a viable alternative for treatment of older patients with OAB, especially for those on anticholinergic medications for other diseases.
