Sex is not always hot. There are times when it becomes dim, and even outages. One reason is penis erection can not always be perfect. But people with impotency should not feel discouraged because the world has found a cure of impotence.
One of the anti impotence drug most widely used worldwide in the market is sildenafil which is often called the blue pill or Viagra. Research had been carried out extensively in many countries are proving that viagra has a high success rate, up 89 percent to trigger an erection.
However, viagra also has side effects. In a systematic review and meta-analysis of 49 clinical research, Dr. Alexander Tsertsvadze of the Ottawa Health Research Institute, Canada, and colleagues reported that men who use Viagra has a risk of side effects as much as 1.5 times greater than those using placebo.
The most common side effect of viagra, these include headache, chest pounding, shortness of breath, and vision problems, flushing (red face due to dilation of blood vessels in your face), and indigestion. Research also shows that the risk of side effects also increases with increasing doses of Viagra.
“Every drug has certain side effects – there’s no drug that has no side effects, including viagra,” said dr. Damian Budhi Widjojo, Primary Care Medical Advisor of PT. Pfizer Indonesia. Sildenafil citrate may only be used when the doctor said that a man had been suffering from impotence. “Of course, only adult men who may use this drug,” he said.
Moreover, to avoid unwanted side effects, Budhi explained viagra are not allowed in patients who are taking heart medications on the nitrate groups. “The use of viagra to patients suffering from heart disease should be careful because there is the possibility that they take medication of nitrate groups or because his heart condition was not optimal for sexual intercourse,” he explained.
In men, blood flow is essential to get good sex. Viagra works by relaxing the smooth muscle, by inhibiting the enzyme fosfodiestrase. Smooth muscles that play a role in impotence is called the corpus cavernosa, a muscle that supports the erection of the penis. In the relaxation condition, the blood flow into the penis so that erection occurs.
