Everything You Need to Know About Sildenafil: Your Questions Answered

Sildenafil has become a household name, largely thanks to its role in treating erectile dysfunction (ED) under brands like Viagra. But beyond the buzz, what exactly is it, how does it work, and what should you know before using it? Whether you’re curious about dosage, duration, safety, or even if women can take it, this blog dives deep into your questions about sildenafil. Let’s clear the air and get the facts straight!

What Is Sildenafil?

Sildenafil is a medication classified as a phosphodiesterase type 5 (PDE5) inhibitor. Originally developed to treat high blood pressure and angina (chest pain), it gained fame when researchers discovered its ability to improve blood flow to the penis, making it a game-changer for ED. Today, it’s widely available as a generic drug, offering the same benefits as Viagra at a lower cost.

How Does Sildenafil Work?

Sildenafil works by enhancing blood flow where it’s needed most. Here’s the science:

• During sexual arousal, your body releases nitric oxide, which triggers the production of cyclic guanosine monophosphate (cGMP).
• cGMP relaxes smooth muscle cells in blood vessels, allowing them to widen and increase blood flow to the penis for an erection.
• PDE5, an enzyme, breaks down cGMP, ending the erection. Sildenafil inhibits PDE5, keeping cGMP levels high, so blood flow and the erection lasts longer.
