Carbenoxolone disodium is primarily used in medical and research applications due to its anti-inflammatory and ulcer-healing properties. It is often employed in the treatment of mouth ulcers and other mucosal injuries, promoting faster healing and reducing discomfort. In research, it is utilized as an inhibitor of 11β-hydroxysteroid dehydrogenase, an enzyme involved in cortisol metabolism, making it valuable in studies related to stress, metabolism, and hormonal regulation. Additionally, it has been explored for its potential neuroprotective effects in conditions like stroke and neurodegenerative diseases. Its ability to modulate gap junctions has also made it a subject of interest in cellular communication studies.
