Cialis - The Best ED Drug

Today, 50% of all men world-wide above the age of 50 years suffer from impotence - scientifically known as Erectile Dysfunction. According to the National Institute of Health (N.I.H.) in 2002, about 25-30 million men in the United States suffered from Erectile Dysfunction. Now, that's a huge number.

Erectile Dysfunction is defined as the inability to get, maintain and sustain an erection for satisfactory sexual intercourse. There have been various causes attributed to it like stress, anxiety, depression, along with diseases like diabetes, renal disease, chronic alcoholism and heart disease (atherosclerosis). Psychological factors are responsible for hardly 25% of the erectile dysfunction cases, while 75% are due to diseases. Almost 50% of men with diabetes will experience erectile dysfunction within 10 years of getting the disease.

While some men can experience complete erectile dysfunction, others can experience partial or infrequent episodes of erectile dysfunction. Most men experience relationship problems and feel a tremendous loss of self esteem due to this.

The process of getting an erection actually begins in the brain when the person is sexually aroused. This causes the release of love chemicals - called neuro-transmitters. These include acetylcholine, epinephrine and nitric oxide. Stimulation of the nerves either by touch or sexual feelings causes an increased blood flow to the penis.

This blood flow into the penis enlarges it and makes it rigid. Because the blood must remain within the penis and keep it hard, the erectile tissue is enclosed by fibrous elastic sheathes that prevent the blood from flowing out during an erection. This continues until the blood pressure is reduced due to lack of sexual stimulation or ejaculation hence, which the penis returns to the normal size.

Now, this is what happens in a normal erection. How then does erectile dysfunction occur? An importance chemical to sustain an erection is cyclic guanosine monophosphate. This higher the levels of this chemical, the stronger the erection as it ensures that the muscles of the penis are relaxed and there is continuous blood flow into the penis. This sex chemical is broken down by an enzyme called as Phosphodiesterase-5(PDE-5) - the villain. The higher the levels of PDE-5, the more the break-down of cGMP and thus more the chances of erectile dysfunction. In men with erectile dysfunction there is faster break-down of cGMP due to diseases or psychological reasons.

According to data available on Men's health, most men quietly suffer from this disorder without seeking treatment. Even in a developed country like the United States. According to the National Ambulatory Medical Care Survey only 2.2% men in the U.S. sought treatment for erectile dysfunction. What could possibly the reason for that. To avoid embarrassment, questions on their virility or just a fatalistic attitude that well, this is a part of the normal aging process.

But today, not only is male impotence no longer a taboo, but with the emergence of good drugs to deal effectively with it, a man can be enjoy good sexual health for as long as desired. To avoid embarrassment, they do not even have to visit a doctor. They just have to log on to the internet, go to the online pharmacy or drug website, fill a form detailing their condition and a prescription is generated online. The drug is home delivered. Clearly, men never had it so good as now.

There are 3 drugs now in the market. All of them act on the enzyme PDE-5. However there are differences in terms of time taken to start producing an erection, for how many hours they can actively work, etc. Let's find out more about them.

The first one was Pfizer's Viagra, which is gradually slipping from it's position as the top drug for erectile dysfunction. It works as fast as 15 minutes, but will only last for 4 hours. It only acts best on an empty stomach and will not act as well if taken with a complete meal. There are a large number of men however who are not able to get satisfactory results with this drug. It does not work very well in diabetics.

The next drug is the Glaxo-Bayer-Schering Plough combine's Levitra. It can work as fast as 16 minutes, but again will only last for 4 hours. A diet rich in fat can impede the working of this drug, especially if it contains more than 62% fat. It is said to be more potent and effective than Viagra, but other than better efficacy in diabetic men it has little to offer.

The best drug however is Lily-Icos's a Cialis . Cialis is a wonder drug that may take 30 minutes to act, but lasts an awesome 36 hours. This means that men can relax with their partners and have sex at their own pace. They do not need to watch the clock. What more, food has absolutely no effect on Cialis. Even a 100% fat diet can not dent the superior efficacy of Cialis.

One can place an order for it, on any of the Cialis online sites. It is widely available, at even lower prices than the other drugs. And since it works for 36 hours hours, you buy less pills per hour and save money. Thus, isn't Cialis the best drug from all points of view. Why wait, go for the best drug. Go for Cialis.
