Alexandria University researchers are investigating nano-technology as a way of creating a skin patch - like those used for nicotine-replacement therapy - to deliver faster-acting and longer lasting doses of impotence / erectile dysfunction medication.

Despite the time it takes to begin working and and its short effective timespan, Viagra remains the oral drug of choice for impotence / erectile dysfunction sufferers. The Alexandria University researchers are working towards a skin patch, with the aim of getting more of Viagra's active component into the blood stream quicker than if it is taken as a pill. If they succeed, this method could deliver a longer-lasting effect than the standard Viagra pill.

Transdermal delivery systems - patches - have been tried before but were beaten by Viagra's chemical characteristics. By incorporating the Viagra in a nano-emulsion, the scientists think they can achieve a formulation that shows promise for a new Viagra patch. And, of course, this technique may prove effective for both Cialis and Levitra as well.

We will keep an eye on this research and update this story.
