# Beta-3 adrenergic antagonist

A Beta-3 adrenergic antagonist $(β_3-adrenoceptor$ antagonist) is an adrenergic antagonist which blocks the Beta-3 adrenergic receptors of cells, with either high specificity (an antagonist which is selective for $β_3$ adrenoceptors) like L-748,328, L-748,337 and SR 59230A or non-specifically (an antagonist for $β_3$ and for $β_1$ or $β_2$ adrenoceptors) like the non-selective betablocker Carvedilol.
