A new gel which can be injected
directly into a joint can provide pain relief for arthritis sufferers. Scientists
used a gel called 'GRAS' that self-packages a liquid drug into gel globules. This gel has the potential to release pain medication in
response to the enzymes when flare-ups occur.
The traditional treatment for arthritis involves taking large doses of oral medications to ensure that enough of it reaches the affected part of the body. Injectables for joint pain have also been around for quite some time but these offer only short-term relief.
This new way of treating arthritis was developed by scientists at the Brigham and Women's Hospital (BWH). Scientists hope that this research could prove to be a platform for multiple medical applications like localized treatment of cancer, ocular diseases and cardiovascular diseases. This will be published in the May 2011 issue of Journal of Biomedical Materials Research.
