Are Beta 3 Adrenergic Agonists Now the Preferred Pharmacologic Management of Overactive Bladder?

This paper discusses the recent evidence supporting beta 3 adrenergic agonists as the preferred pharmacological management of overactive bladder syndrome.

Mirabegron has a similar efficacy profile to first-line antimuscarinics with favorable adverse effects profile. Treatment of OAB with beta-3 adrenergic agonist should be favored in patients at higher risk of anticholinergic adverse events. The efficacy and tolerability of beta-3 adrenergic agonists are consistently reported in older OAB patients, whether used alone or with other antimuscarinics. Mirabegron is cost-effective in treating OAB unless the symptoms were severe or refractory. Combination therapy of mirabegron and other pharmacotherapy has proven to be efficient in controlling OAB symptoms without inducing serious add-on adverse effects. While beta-3 adrenergic agonists bear favorable advantages in OAB treatment, physicians should perform a thorough and careful pre-treatment planning to optimize treatment benefits and adherence.
