When you hear sildenafil citrate, the active ingredient in Viagra and other medications used to treat erectile dysfunction and pulmonary arterial hypertension. Also known as generic Viagra, it works by relaxing blood vessels and increasing blood flow to specific areas of the body—most commonly the penis, but also the lungs in certain medical conditions. It’s not a magic pill. It doesn’t create desire. It simply helps your body respond to sexual stimulation the way it should when natural processes aren’t working right.
Sildenafil citrate belongs to a class of drugs called phosphodiesterase inhibitors. That’s a mouthful, but here’s what it means in plain terms: it stops an enzyme from breaking down a chemical your body makes naturally during arousal. That chemical, cGMP, keeps blood vessels open so blood can flow in. More blood flow = stronger, longer-lasting erections. It’s the same mechanism that helps people with pulmonary arterial hypertension breathe easier—by opening up blood vessels in the lungs. The science is solid, and it’s been used safely by millions since the late 1990s.
People often confuse sildenafil citrate with brand-name Viagra, but they’re the same thing chemically. The difference is cost. Generic sildenafil citrate works just as well, often for a fraction of the price. You’ll find it sold under dozens of names—Cialis and Levitra are different drugs, but many shoppers mix them up. Sildenafil is also used off-label for altitude sickness and some forms of Raynaud’s phenomenon. Not everyone responds the same way. Some need 25 mg. Others need 100 mg. It’s not one-size-fits-all.
It’s not without risks. If you’re on nitrates for chest pain, taking sildenafil can drop your blood pressure to dangerous levels. Alcohol can make side effects like dizziness or headaches worse. And if you’re buying online, you’re gambling with your health—counterfeit pills with wrong doses or toxic fillers are common. That’s why knowing what you’re taking matters.
