Try Viagra 50mg. See What it Can Do For You!

We know there are many treatment options out there today for erectile dysfunction and each person needs to choose the option that is right for them. That’s why we made it our goal to bring you all the facts, enabling you to make a more educated decision. So go ahead, read up on the product and find out everything that you need to know.

Let’s begin by explaining the history behind Viagra. Few people know that Sildenafil citrate (more popularly known as Viagra) is not just a drug used to treat erectile dysfunction, but is also manufactured and FDA-approved to treat the symptoms of pulmonary arterial hypertension (PAH). If you think about how Sildenafil citrate works, you’ll see that the two conditions have something in common.

Pulmonary arterial hypertension occurs when the pulmonary arteries resists effectively pumping blood. PDE5, that famous enzyme that increases and improves blood flow to the penis to treat impotence, also works to decrease arterial pressure and resistance. The trade name for Sildenafil when it’s used to treat pulmonary arterial hypertension is Revatio.

When someone takes Sildenafil citrate—in either its Viagra or Revatio forms—the PDE5 travels to the arterial walls of the lungs and penis. It is evenly distributed, improving the blood flow.

For someone who suffers from erectile dysfunction, the result of this PDE5 will be harder, longer-lasting erections. For someone with PAH, the improved blood flow will eliminate uncomfortable and deadly symptoms of shortness of breath, fainting, dizziness, and eventual heart failure.

The Sildenafil dosages are different for Viagra-users and Revatio-users. Men who take Viagra usually take between 25mg and 100mg, not more than one time each day, about 30 minutes before engaging in sexual intercourse. PAH sufferers who take Revatio, on the other hand, take one 20mg pill three times per day.

Another difference, Viagra tablets are light blue diamond-shaped tablets; Revatio pills are white, round, and film-coated.

So now we know that Sildenafil citrate treats erectile dysfunction and pulmonary arterial hypertension. Are there any other conditions that it treats?

Studies show that Sildenafil also treats and prevents high altitude pulmonary edema, a condition associated with altitude sickness. Research is still being done to confirm this, but it is becoming quite common among mountain climbers to take Sildenafil before engaging in rapid decent.

Other uses of Sildenafil include recreational use among athletes who believe that when the Sildenafil opens their blood vessels, their muscles will expand, thereby improving their athletic performance.

Research currently shows that Sildenafil may also be effective in treating jet lag.
