The generic version of Viagra, a world-known anti-impotence pill, is anticipated by many men and their doctors around the globe; and this is quite natural and understandable, since the generic Viagra could significantly lower the cost of erectile dysfunction treatment.
The main working ingredient of Viagra, and thus basically started the new age of impotence treatment with PDE-5 inhibitors.
According to the legislation of the USA, generic versions of the brand-name medications are not allowed to be manufactured until the expiration of the original product patent. In such a way the law protects all those investments, made by a company during the investigation, development, and clinical testing of the new drug.
The patent on Viagra is expected to expire on March 27, 2012 according to the information available on the site of the United States Patent and Trademark Office. So, only after that date other pharmaceutical companies will be permitted to manufacture generic sildenafil. By the way, the first application for generic sildenafil citrate by TEVA Pharams has already received the FDA tentative approval.
On the other hand, the patent legislation differs in different parts of the world. While in the USA Viagra patent stays effective at least until 2012 (provided that Pfizer won’t get the prolongation of the patent), in other countries, such as China for example, the patent on Viagra has already been overturned.Such situation has already resulted in the “premature” appearance of Viagra generic versions, supplied under such names as Kamagra, Caverta, Silagra, or simply sildenafil from India and other Asian countries.
The problem is that such 100% natural sexual boosters often contain undeclared sildenafil . Adding the active ingredient from Viagra makes such a remedy really effective against impotence; but, on the other hand, hiding this fact and claiming the product to be made of completely natural components creates a vision of perfect safety of the product in the eyes of customers.
By taking such kind of anti-impotence herbal remedy without knowing its true components, a man may put his health at serious risk, because sildenafil is a chemical, which may cause side effects, lead to allergic complications, or counteract with other medications. Besides, in order to avoid overdose the amount of sildenafil is precisely measured in every Viagra pill, which is not usually a case with food supplements.
The U.S. Food and Drug Administration regularly warns consumers about the danger of anti-impotence treatments, promoted as herbal remedies or food supplements. Blue Steel, Hero, Super Shangai, Strong Testis, Shangai Ultra, Energy max, True Man Sexual Energy – this is only a small part of products, which were found to contain undeclared and unapproved ingredients similar to sildenafil from Viagra.

Making a conclusion about Viagra and its cheap alternatives, an ancient wisdom comes to mind, which says that people tend to choose the lesser among two evils. Until final expiration of original Viagra patent, any of the available generic alternatives seems to be risky at least from the point of view of legislation; but those products, in which the presence of sildenafil is hidden by manufacturers, are definitely of much worse danger for people, trying to find cheaper solution to the problem of impotence.
