Hydrogen sulphide, the gas responsible for the terrible smell of rotten eggs, has been found to play a role in the biochemical response that leads to an erection.  The discovery may lead to a new medical therapy for Erectile Dysfunction.

In the Proceedings of the National Academy of Sciences, Italian researchers showed that hydrogen sulphide is released into the erectile tissues prior to erections occurring.  Current Erectile Dysfunction drugs, such as Viagra, Cialis and Levitra, target nitric oxide, another mediator in erections.

In some rare cases, men do not respond to the current Erectile Dysfunction drugs which target the nitric oxide pathway.  New medications directed at hydrogen sulphide would hold promise for these patients.

A recent study published in the Journal of Urology showed a surprising benefit for Cialis (tadalafil) users.  Men using a lower daily dose of the ED medication (2.5 or 5mg) were shown to have statistically significant improvement in troublesome urinary symptoms such as waking up at night to urinate (nocturia), urinary frequency, and poor bladder emptying.  The mechanism for this action is not well understood at present.

In the future, combination drugs which target ED and prostate symptoms (including possible protective or preventative therapy directed against prostate cancer)  are likely to be investigated.

KwikMed's customer service team receives numerous questions every week from our customers regarding generic Viagra the risks involved when purchasing medications online.

When buying Viagra online it is very important to understand the risks involved when dealing with unregulated online pharmacies. There has been a sharp rise in the number of counterfeit pharmaceutical products being sold online. These fake products may look like the real thing but do not contain the proper substances and can be very dangerous.

It is also important to realize that there is no such thing as "generic" Viagra, Cialis, or Levitra. Although you frequently see these "generic" erectile dysfunction medicines being advertised online they are not legal and it's illegal to sell "generic" Viagra, Cialis, or Levitra in the United States. These impotence drugs are not FDA approved which means you cannot be sure that these products are effective or safe.

The Pfizer website provides guidelines for buying Pfizer Viagra and notes that there are thousands of websites selling fake Viagra. It urges you to protect yourself and stay away from any sites selling "generic" Viagra, Viagra soft tabs, and quick-dissolving Viagra as these are all forms of fake Viagra.
