A new patch, which sticks to the inner lining of the cheek like an octopus sucker, effectively delivered two drugs in dogs and passed safety tests in humans.
Scientists have developed a new device inspired by octopus suckers that can deliver drugs without requiring needles or pills. They've already tested it in humans in a small, short trial.
Further development is needed. However, the patch could represent a less invasive and more comfortable approach to drug delivery, especially for larger drugs that are poorly absorbed by the digestive system so can normally only be injected using needles. Other ways of delivering large drugs to the body, for example via the nose or using microneedles applied to the skin or in capsules, can be inefficient and difficult to make, the study authors wrote.
