Originally developed in the 1990's to treat angina pectoris, which is a heart condition, it became clear that the drug did nothing to alleviate this disease. However, it consistently produced erections in the male patients it was given to. So all was not lost! By 1998, it had passed all of the FDA's tests and was introduced to the general public. Immediately, it became quite popular.
Viagra is a PDE5 inhibitor. This means that the compound cyclic GMP breaks down, and causes the arterial smooth muscles in the penis to relax. This allows the penis to become engorged, thus creating an erection. When the action of PDE5 is stopped or restricted, an erection will occur if you are otherwise healthy.
In many cases of Erectile Dysfunction, Viagra has been very effective. However, if your ED is being caused by nerve damage, hypogonadism, or diabetes, Viagra will most likely not work for you. A doctor will probably want to test you for such things before prescribing an ED medication such as Viagra. If your tests come back clean, you should be on your way to a more exciting sex life.
While Viagra may be a miracle drug for many men, it does not come without a few side effects. These include headaches, flushing, sweating, and upset stomach. Some men have reported blurred vision, and there have been a very few rare instances of temporary blindness. For most healthy men, however, these side effects are either mild or temporary.
If you are taking any drug to treat angina pectoris, you should not take Viagra. These two drugs in your system can result in a dangerous dip in blood pressure that could be quite serious. In addition, while it can be bought over the Internet, you should always talk to your doctor before you take any medication, and this includes Viagra. It is understandable that if you suffer from Erectile Dysfunction, you will want to try anything that could remedy this. But it won't do you any good if it's only going to put your life in danger.
