A unique feature of Nebivolol (Bystolic) is:

  1. It only blocks alpha receptors

  2. It causes significant sexual dysfunction

  3. It also produces vasodilation

  4. It is the oldest beta blocker

The correct answer is: It also produces vasodilation

Nebivolol (Bystolic) is a beta blocker that is unique due to its ability to also produce vasodilation. This is achieved through activation of endothelial nitric oxide synthase, leading to the release of nitric oxide which causes smooth muscle relaxation and vasodilation. Option A is incorrect because Nebivolol blocks both beta and alpha receptors. Option B is incorrect because Nebivolol has a lower incidence of sexual dysfunction compared to other beta blockers. Option D is incorrect because Nebivolol was approved by the FDA in 2007, making it a relatively new beta blocker on the market.
