How Tadalafil Works
Before we explain how Tadalafil helps manage ED, we need to explain how erections occur naturally. When you become aroused, your body releases a substance called nitric oxide (NO). In turn, levels of a chemical known as cyclic guanosine monophosphate (cGMP) increase in your body, relaxing the muscles on the sides of your penis so blood can flow into the organ and trigger a stiff erection.
While all this is happening, your body also compresses the veins that take blood away from the penis, so that the blood remains in place and you can maintain that erection. Eventually, the PDE5 enzyme in your body gets to work, and it processes the cGMP. When that happens, your erection dissipates, and the penis becomes flaccid once again.
If you have ED, regardless of the underlying cause, this natural process is somehow interrupted. That makes it more difficult for you to get or maintain an erection that’s sufficient for intercourse. And that’s where Tadalafil, a PDE5 inhibitor, can help. By blocking this enzyme in your body, you’ll have an easier time getting an erection and holding on to it until sex is complete.
