London: Many people with diabetes or cancer have to go through painful injections everyday.Since substances like insulin do not penetrate tissue quickly enough to be effective when taken orally, injections has been the only option to deliver such drugs.Now, a pill that uses ultrasound to speed up drug delivery could end the need for these painful daily injections.For years, ultrasound has been used to accelerate the transfer of drugs through skin and can increase drug absorption by a factor of 10.The method works by heating up molecules inside skin tissue, making cell membranes more permeable. It is particularly good for delivering protein-based drugs such as some cancer medicines, insulin and various vaccinations.Now, biomedical engineering company, Zetroz, has applied this technique to design their new pill, called uPill.
