Many men suffer from erectile dysfunction i.e. the incapability to get and uphold an erection long enough to have a satisfying sex. There are man reasons why ED is most visible in men over 45. The sex drive is often decreased even further in older men who use medicines of various kinds. There is a misconception about sex that sex drive steadily lessens, as our age progresses ahead, so we accept ED as a natural problem. But the fact is that for many men ED may be more the result of treatable physical conditions rather than an actual loss of sex drive. In many cases, ED is the result of over burden on man’s body and his brain. Specialists in this field believe that impotence affects between 10 and 15 million men in America. Impotence usually has a physical cause such as some disease, any injury or drug side effects. Any problem that harms blood flow in the penis has the power to cause impotence. Incidence rises with age. About 5 percent of men at the age of 40 and between 15 and 25 percent of men at the age of 65 experience ED. Still, it is not an inevitable part of aging. But with the launch of viagra in 1998, things have changed.

The force of this drug has been gigantic, not just in the region of curing ED for which FDA passed it, but also in the way we feel about sex and sexuality, and even in the area of interaction between male and female. Millions of men have tried Pfizer’s miraculous medicine sildenafil, popularly known as viagra in the united states, and there are thus millions of females who have also noticed its effects on their husbands, boyfriends, and lovers and achieved what we called is orgasm. Viagra is totally different from other ED drugs that have been in the market for over the years now. It has positive advantages and qualities that put the drug in the class of “different from others”. Its effects last long and this satisfies people suffering from ED. The working mechanism of viagra is almost same as evaluated with other ed drugs present in the market today but it has the ability to target the targeting area i.e. pde5 receptors in a enhanced mode. There are other ED drugs also in the market but people have faith in viagra because it has proven records of satisfaction. The success rate of viagra is very superior and extremely praiseworthy as compared to other drugs. It has been researched that more than 80% of people consuming viagra have expressed their fulfillment of sexual needs. Studies have shown that it works twice as fast as any other ED drug and that too with fewer side effects.

Sildenafil citrate is an active ingredient of this most popular ED drug viagra. Viagra is used in a treatment for men experiencing erectile dysfunction. Viagra’s mission is to work on enzymes of the body called phosphodiesterase and to improve man’s response to sexual stimulation. These enzymes work primarily inside the penis, so the action of sildenafil or viagra is limited only to the penis. Viagra works to have control over the enzyme, and by doing so it normalizes and regulates the blood flow out of the penis and thereby helping the man maintain an erection. Sildenafil citrate improves the erection of most men, doesn’t matter how long they have been suffering from the problem of ED. So the time spent with one’s partner during sex can be sexually more active and arousing.

Normally, the treatment is started with the dose of 25 mg, which can be increased or decreased observing the working and the side effects of this drug. Normally it can be taken anytime from 30 minutes to 4 hours before sexual intercourse. The best thing about viagra is that it the pill that can also be used by those who are not suffering from ED, and also by those who are looking for extra stamina for sex. Generally, it is advised that person above 65 years of age should be more cautious using this pill. The good thing about this pill is that it will not start working unless some foreplay is conducted. Viagra does not replace stimulation.

There are certain side effects that have been reported. Nearly 5% of patients consuming viagra reported minor side effects such as headaches and heartburn. It is not recommended for people having heart disease and consuming drugs that lower blood pressure. Others can use it safely. The pde5 receptors have to be targeted effectively in order to avert the side effects associated with the ED drugs. The most common side effects of sildenafil citrate are headache, flushing of the face and upset stomach. Less common side effects that may occur are temporary changes in color vision (such as trouble telling the difference between blue and green objects or having a blue color tinge to them), eyes being more sensitive to light or blurred vision. In exceptional occasion, men have reported an erection that lasts many hours. One should call a doctor immediately if he ever has an erection that lasts more than 4 hours. If not treated right away, it might damage the penis permanently.

Now that cheap viagra is accessible very easily, there is no chance that any can’t buy or get viagra. Buying viagra is not a big task because online viagra pharmacy is in countless numbers. These viagra pharmacies offer huge discounts on viagra.

I don’t see any reason why a person suffering from erectile dysfunction would not prefer viagra. After all it is the drug, which has all the qualities, which are needed in a drug, used to treat ED to be a successful drug, and that is what viagra is.
