A clear skin patch called TEPI delivers the painkiller ibuprofen right where it hurts.

While pills can cause stomach upset,but not the patch.

Scientists at the University of Warwick in England developed it and adhesive infused with the painkiller.

"Up to 30 percent of the adhesive will be the ibuprofen. And then, when that's placed on the skin just like an, then the drug will actually diffuse across the skin into the body at the site of the pain, and then relieve the pain the same way as current gels and creams."

The ibuprofen patch could deliver uninterrupted pain relief for up to 24 hours.

The patch is being manufactured by Medherant, a bioadhesive company affiliated with the University.

"We've been in the lab about 12 months,but in the 12 months, we've essentially assessed about 90 percent of the drugs that are currently available as either creams or patches. We've tested them in our polymers with very good results."
