Scientists have developed a high-tech patches for pain relief that delivers pain-relief drugs for arthritis when it is stretched. A problem with standard pills or injections is that they take some time to work, while rub-on pain-relief gels and creams need to be reapplied and patients can still feel pain between applications. With the new plaster, the drug is released whenever an arthritic joint is moved.Medication that needs to be used throughout the day, such as antibiotics, can be loaded into the plaster and will be released without the need to remember to take more. The elastic patch - which is the size of a large, everyday plaster - is made from a plastic film impregnated with tiny capsules that are loaded with tiny balls of the required drug. The capsules are on the plaster's inner surface and touch the skin. When the plaster is stretched - for example, when a joint is bent or moved - the capsules are pulled out of shape and release some of the drug inside.
The ingredients can be absorbed through pores and is delivered to the target tissue. Once emptied, the capsules revert to their original shape and are refilled from an internal reservoir.
Where the patches for pain relief is applied on the body will determine how much it is stretched and how regularly the ingredients will be delivered. The patient can also stretch the plaster themselves to release the ingredients on demand.
