Viagra has a unique history. At first it is tend be invented to cure high blood pressure and angina. On its experiment, it had a tremendous effect. Most men in this experiment didn’t return the rest of sample pills.
Then the researchers thought of something must be going on. And they found out that the pills had another interesting effect as a strength medicine for men.
Today million of Viagra doses have sold in many countries around the world. Viagra pill is being acclaimed as the first medicine to cure erectile dysfunction or men’s impotence. Besides viagra, there are three impotence drugs that recommended by doctors, they are Levitra, Cialis and Viagra.
Viagra Working Methode
Viagra is not a stimulation medicine even though it has a strong relation toward men’s power. Viagra enable to stimulate someone’s sexual desire when he doesn’t have the intention.
Viagra will work well when there is already sexual stimulation. It is important for people who want to consume Viagra pill to know how Viagra works and reacts inside human body.
Viagra working method has strong relation with erection. When a man got stimulate, his brain will send signal to his sex organ. The sex organ will then create cyclic GMP hormone. This hormone will wide up the vein for sex organ blood circulation.
When the vein become wider, sex organ will fulfill with blood. It becomes big, hard and strong. That is erection. As long as the level of cyclic GMP production is enough, erection will remain still.
However, human body has another mechanism as cyclic GMP balancing. Otherwise, a man will have continuously erection. The balancing is phosphodiesterase (PDE5) where it can destroy cyclic GMP. When cyclic GMP break, vein will be narrow again and erection will stop.
Viagra (sildenafil citrate) works as PDE inhibitor. It is simple logic, when PDE is being hold, then cyclic GMP will not ruin. As the result sex organ will remain wide. This effect will occur until levels of sildenafil citrate in blood become less.
Consuming Viagra continuously will create side effects like headache, blurriness, and stomachache. High doses will also cause visual trouble like unable to differentiate blue and green.
Dr. Akmal Taher explained that erection happen because of widen vein in penis. However it also widen up another vein in other parts of body. And that is the one that causing the side effects. He also added that when Viagra consume together with nitrate medicine, it has a risk of death because the vein will be wide tremendously.
However, this is has a significant succeed around 60-80%, based on the experiment towards 3.700 men at the age between 19 and 87 year-old with many impotency levels.
Research had shown that more than 140 million men in the world are having erectile dysfunction or impotence. And even though Viagra can be the best solution for those men, it doesn’t mean that this medicine is fits for everyone or every case of impotence. That is why always consult with doctors before using Viagra.
Doctor Prescription
Just like any other medicine, Viagra also has several side effects like headache, stomachache, cold, diarrhea, and migrant. It is viagra controversy. Sometimes visual disturbance occurs to some patients. When erection occur too long that what it should be, stop taking it and consult to the doctor as soon as possible.
Viagra can also arouse allergic reaction like itchy, red skin, swollen and hard breathing. When those allergic reactions occur, go to the doctor also immediately.
On June 9, 1998, FDA reported 16 men died after consuming Viagra. According to Wall Street Journal on Monday, June 29, 1998, it increased become 30 men. The oldest victim was at the age of 80 and the youngest one was at the age of 48.
Examining result has showed that most of the consumers are having heart disease, diabetes and other complication treatment. One of the victims is having chronic irregular pulse and having his heart blood circulation got hold. He died after having sexual activities.

There was also victim who had chest pain after taking Viagra while having sex. He was given nitroglycerine in the ambulance but unable to survive. Another victim was on insulin therapy, he died straight away after taking Viagra.
Other four victims didn’t have disease history but also died after consuming Viagra. Even though it hasn’t been proven yet of Viagra direct affect towards those death, but it has built pro and contra in using this blue pill.
Dr. Adolf Hutter, heart expertise from General Hospital Massachusetts and Harvard Medical School in Boston, tends to think that those victims heart attack is because of their over physical and emotion excitement in doing their sexual activities after no long time of failure.
Similar thought was also being said by Dr. Kamal Taher. He said that if we speak about 1 million people at the age of 50 who have heart disease, without taking any medicine like Viagra, they will also die if having too much excitement in their sexual activities.
Many researches throughout Europe and America had shown that no controlled men died after taking Viagra. But still, it is better to take Viagra with the right doses.
