When it comes to erectile dysfunction (ED), one of the most common questions men have is: “How do medications like Viagra, Cialis, or Levitra actually work?”
The short answer: They help your body use its natural blood-flow signals more effectively. Let’s break it down in simple terms.
What is cGMP — and Why Does It Matter?
Inside your blood vessels, your body makes a “messenger” molecule called cGMP (cyclic guanosine monophosphate).
Think of cGMP as a green light telling blood vessels to relax and open up. When that happens, blood can flow more easily — including into the penis during sexual arousal.
The Role of PDE5 — The “Traffic Cop”
Your body also produces an enzyme called PDE5 (phosphodiesterase type 5).
PDE5’s job is to break down cGMP — in other words, it’s like a traffic cop that turns the green light red too quickly.
When PDE5 breaks down cGMP, blood flow slows, and an erection fades.
How PDE5 Inhibitors Work
This is where medications like Viagra (sildenafil), Cialis (tadalafil), and Levitra (vardenafil) come in. These are called PDE5 inhibitors.
👉 By blocking PDE5, these medicines let cGMP stick around longer.
👉 That means the green light stays on, blood vessels stay open, and blood flow improves.
👉 Result: firmer, longer-lasting erections — but only when you’re sexually stimulated.
An Easy Analogy
-
Without medication: cGMP gives the green light, but PDE5 quickly shuts it down.
-
With a PDE5 inhibitor: PDE5 is blocked, so cGMP keeps the green light on, and blood keeps flowing.
It’s not that the medication forces an erection. Instead, it helps your body’s natural system work the way it’s supposed to.
Why This Matters Beyond ED
Did you know PDE5 inhibitors aren’t just for ED? They’re also used in conditions like pulmonary hypertension, where relaxing blood vessels in the lungs reduces strain on the heart.
At NuWave Total Wellness, we focus on the sexual wellness side — helping men restore confidence, intimacy, and performance safely.
Are PDE5 Inhibitors Right for You?
For many men, these medications are effective and safe when prescribed under medical supervision. But they’re not the only solution. At NuWave Total Wellness, we also offer GAINSWave® therapy, the P-Shot®, and other advanced treatments designed to address the root cause of ED, not just the symptoms.
The Bottom Line
PDE5 inhibitors work by helping your body keep the “blood flow green light” on longer. They don’t replace natural arousal — they simply give your body the support it needs to achieve and maintain stronger erections.
If you’re struggling with ED, you don’t have to settle. There are safe, proven options that can help you restore confidence and enjoy intimacy again.
