'Viagra cream' could prove safer

Researchers using nanoparticles each much smaller than a grain of pollen containing Cialis, a newer erectile dysfunction drug called sialorphin, and nitric oxide had erectile responses in just a few minutes. Oral medications can take 30 minutes to one hour for oral erectile dysfunction medications to take effect.

Presumably this drug vehicle would have a faster onset with fewer systemic side effects.

A cream allowing erectile dysfunction drugs to be applied directly to the skin could one day make them safer to use, say New York scientists.

The research, published in the Journal of Sexual Medicine, could mean fewer side-effects, and even significantly speed up the drug's action.

However, although they (oral pills) have worked for many men, they also carry the risk of side-effects such as headaches, blurred vision or upset stomachs.

In addition, men with severe heart problems, or who have just suffered a stroke, are advised to avoid the tablets altogether or use them with extreme caution.
