Function

Mirabegron is an orally active β3-adrenoceptor agonist currently in development by Astellas Pharma for the treatment of overactive bladder (OAB). The drug is a nanomolar EC50 antagonist against human β3-AR biochemical assays with good selectivity over b1- and β2-ARs. Mirabegron demonstrates a novel mechanism by targeting the β3-AR for bladder relaxation to help manage OAB symptoms such as increased urinary urgency and frequency and urgency incontinence. However, mirabegron is a cytochrome P450 2D6 inhibitor, and it raises a concern for drug-drug interaction with concomitant administration of other cytochrome P450 2D6 substrates.
Potent bladder relaxant and reagent for diabetes remedy.;Labeled Mirabegron, intended for use as an internal standard for the quantification of Mirabegron by GC- or LC-mass spectrometry.
