Mirabegron is the first beta-3 adrenoceptor agonist. Mirabegron exerts its effect via a dual mechanism, both directly acts on the bladder smooth muscle and also via the sensory nervous system, it increases the levels of cyclic adenosine monophosphate (cyclic AMP) and leads to relaxation of the detrusor smooth muscle during storage phase of urinary bladder fill-void cycle by activation of beta-3 adrenoceptor which increase bladder capacity.
