Drugs could be released into the body exactly where they are needed using a highly targeted ultrasound beam, according to new research that could revolutionise the way medications are administered.Current methods of administering drugs - whether it's swallowed, injected, inhaled, or absorbed through the skin - mean that it ultimately diffuses to most parts of the body, including those where it isn't needed or could even cause harm.It's hoped that targeting the drug to exactly the right spot would allow the total dose needed to be dramatically lower, minimising adverse side effects.
