Kant was the embodiment of success. Touching 50 years - he felt on top of the world. He had everything he wanted a warm loving family, excellent career, holidays abroad, two homes- the list just goes on and on.

But every night, he went to bed with that strange feeling of desperate hope. Hope for a normal erection. No matter, what he did, there was no benefit. He tried all kinds of aphrodisiacs, creams, lotions and even herbal products, but to no avail. All this was taking a toll on his self esteem. Finally on the prodding of his wife, he went to a doctor, who immediately diagnosed him as suffering from erectile dysfunction. He prescribed Viagra, the latest blockbuster drug, which every news article said worked wonders. Kant felt truly busted by the drug when it did not work.

Just when he thought he had no hope, that Levitra was launched in August 2003. His doctor immediately called and asked him to try out this amazing new drug. It was that one tablet that gave back Kant, within 15 minutes, that important thing that he almost lost-Hope. He had an erection after 5 years and was successfully able to perform sex. He felt like Superman. He had to, after taking a drug that had surpassed all expectations, by being the ideal drug in the treatment of Erectile Dysfunction. Levitra had truly levitated him to a higher plane, just as it did, for the thousand of other men, who were prescribed it. For him it was the essential thing for sex.

Erectile dysfunction is defined as the recurrent inability of a man to attain or maintain an erection of the penis required for normal sexual function. It affects more than half the men over 40 years of age. An estimated 160 million men today worldwide suffer from Erectile Dysfunction. By 2025 this number is expected to swell to 325 million as the world population ages.

Currently only a very low percentage of men are actively seeking treatment for disorder. In countries like India, the percentage is as low as 1-3%. Viagra has been the mainstay of treatment for the last few years, but with the coming of Levitra, this is bound to change.

Levitra contains Vardenafil Citrate, the latest generation PDE-5 inhibitors. It acts on the enzyme phosphodiasterase-5 which plays a crucial role in controlling the levels of cGMP (cyclic guanocin monophosphate), responsible for relaxation of the smooth muscles. It is the relaxation of the smooth muscles that enables blood to flow to the penis ensuring an erection. PDE-5 is responsible for the breakdown of cGMP. Levitra acts to inhibit PDE-5 and playing a very important role in ensuring an erection.

Levitra was developed by the Bayer AG, Glaxosmithkline Beecham and S. Plough Corp after years of research. They launched the drug in August 2003 in the United States. It is only this formulation that is approved by US-FDA. This US-FDA approved Levitra is different from the generic variants which may not have the same efficacy and may have potentially dangerous side-effects for patients.

The superiority of Levitra was proved by a very conclusive study called the PROVEN Study carried out in 463 men. All the men given Levitra had earlier tried Viagra at least 6 times with no success. All of the study participants had also tried the highest dose of 100mg of Viagra with no success. Levitra proved to be highly effective. Men were 3 times more likely to complete sexual intercourse with Levitra then with placebo. This study clearly proved the superiority of Levitra over Viagra.

The biggest advantage of sex with Levitra is that is highly selective and acts only on PDE-5 and not on other enzymes, thus a smaller dose e.g. 10 mg is as potent as a larger dose e.g. 50 mg of Viagra. The other advantage is that Levitra works very well is patients with diabetes who have impotence problems.

Levitra is available as 2.5 mg, 5 mg, 10 mg and 20 mg tablets. Doctors usually start with a starting dose of 10 mg and either increase the dose to 20 mg or reduce it to 2.5 mg as per the patient needs. It can be taken regardless of the last meal 60 minutes at least before sex and it's efficacy is not affected by the food eaten

In Geriatrics, that is those above 65 years of age a starting dose of 5 mg must be considered. It should be used with caution in patients with renal and hepatic impairment. Levitra cannot be taken by patients on nitrates taken for angina or pain in the chest.

The most common side-effects include headaches, flushing and runny nose, but other-wise this drug is very safe. You can get more Levitra information on at levitra.com, the official website.
