Mirabegron Pharmacology

Mirabegron is a beta-3 agonist that can help relax bladder smooth muscle and manage symptoms of overactive bladder. Mirabegron inhibits CYP2D6 which can negatively impact the effectiveness of tamoxifen. I discuss this in greater detail in the podcast. Tramadol and codeine effectiveness can be impacted by mirabegron. Be aware of this when using this medication. By inhibiting CYP2D6, mirabegron can increase the concentrations of many psychotropic medications such as fluoxetine, aripiprazole, clozapine, and paroxetine. I discuss this further in this episode of the podcast. Be sure to check out our free Top 200 study guide – a 31 page PDF that is yours for FREE!
