R-22-GA204

R-22-GA204 is a clinical-stage therapeutic candidate being developed by Dong-A Pharmaceutical for the treatment of dentin hypersensitivity. Dentin hypersensitivity is a common dental condition characterized by short, sharp pain arising from exposed dentin in response to external stimuli such as thermal, chemical, or tactile triggers. R-22-GA204 is part of Dong-A's oral care R&D pipeline within its consumer health division. While specific details regarding its chemical composition are not publicly disclosed, it is designed to provide relief by either occluding exposed dentinal tubules or desensitizing the intradental nerves. The product is currently undergoing clinical evaluation to establish its safety and efficacy in reducing tooth sensitivity.
