Plaster which sticks inside the mouth will revolutionize treatment of oral conditions
A plaster which sticks to the inside of your mouth is revolutionizing the treatment of painful recurring ulcers.
Scientists from the University of Sheffield’s School of Clinical Dentistry, working in close collaboration with Dermtreat A/S from Copenhagen, have developed a unique patch using special polymers which are able to stick to moist surfaces, eurekalert.org reported.
The patch successfully administers steroids directly to oral ulcers or lesions whilst also creating a protective barrier around the affected area, accelerating the healing process.
The novel plaster is a breakthrough therapy for the treatment of mucosal conditions such as oral lichen planus (OLP) and recurrent aphthous stomatitis (RAS), which are diseases that cause painful lesions and affect one to two percent of the population.
Until now, ulcers and lesions inside the mouth have been treated using either creams or mouthwashes, which are used in the whole mouth rather than targeting the specific area, making them less effective. However, the biodegradable Rivelin® patch, has a long adhesion time and a high flexibility which conforms to the surface inside the mouth.
Dr .Craig Murdoch, reader in Oral Bioscience School of Clinical Dentistry and lead author of the research, said: “Chronic inflammatory conditions such as OLP and RAS, which cause erosive and painful oral lesions, have a considerable impact on quality of life.
“Current treatments consist of using steroids in the form of mouthwashes, creams or ointments, but these are often ineffective due to inadequate drug contact times with the lesion.
“The patch acts like a plaster inside your mouth, which means it is very effective at directly targeting the specific area as well as forming a protective barrier.
“Patients who have trialed the patch found it to be very comfortable to wear and they were really pleased with the length of adhesion which makes it particularly effective and efficient.”
Jens Hansen, chief executive officer at Dermtreat A/S, added: “Collaboration with the University of Sheffield has undoubtedly accelerated the translation of our intellectual property towards clinical use. Our company are very confident that we will soon gain regulatory approval for the first adhesive drug delivery technology to address pressing clinical needs in oral medicine.
