Brief Summary:
The only class of oral erectile dysfunction (ED) medication on the market are the phosphodiesterase Type 5 inhibitors (PDE5i). This pilot study is being done to evaluate the effect of Mirabegron, an oral beta-3 adrenergic agonist, on men with both Overactive Bladder (OAB) symptoms and mild to moderate ED.
Detailed Description:
ED affects up to 30 million men in the United States. The only class of oral medication approved for ED is PDE5i. These include sildenafil, tadalafil, vardenafil and avanafil. Other pharmacologic options in the treatment of ED are delivered as an intraurethral suppository (alprostadil) or intracavernosal injection (alprostadil, papaverine, phentolamine, atropine). These are more invasive routes of administration. Men who fail to obtain benefit from a PDE5i or those who have a contraindication to this class of medication may ultimately avoid further pharmacologic treatment options. An alternative class of oral medication to treat ED may prove to be of benefit to a large population of underserved men.
There is in vitro evidence that beta-3 adrenergic receptors exist in human corpus cavernosum tissue. Activation of these receptors results in vasorelaxation, suggesting a potential pro-erectogenic effect is possible in vivo. Additionally, nebivolol, a beta-blocker, has pro-erectogenic effects noted in several studies. There is evidence that nebivolol exerts beta-3 adrenergic agonism, which may explain the mechanism by which these effects occur.
Mirabegron is the only available beta-3 adrenergic agonist in the United States. Its favorable safety profile and the potential for therapeutic efficacy in ED make it suitable for further investigation.
It is hypothesized that beta-3 adrenergic activation offers a pharmacologic target for the treatment of ED. Men with mild, mild to moderate, or moderate ED and symptoms of OAB can be recruited with pre- and post- Mirabegron administration assessment of their ED to determine the validity of this hypothesis. Men with severe ED will be excluded as historical data shows they are less likely to benefit from oral pharmacologic therapy alone. Mirabegron is approved by the U.S. Food and Drug Administration (FDA) for the treatment of adults with OAB.
