London: A revolutionary skin patch that can treat high blood pressure and slash deaths from heart attacks and strokes has been developed and cleared for use in Japan. The patch, invented by a Japanese firm, needs to be changed every day. It gradually allows a drug to seep through the skin and into the bloodstream once patients stick it on to their arm, chest or back. It provides a steady flow of bisoprolol, which is a type of beta-blocker - unlike pills which can cause blood pressure levels to peak and trough dangerously. Experts believe that having a constant and steady supply of the drug could reduce the incidence of heart attacks and strokes.
