Common Name | Ecabet |

Description | Ecabet is a prescription eye drop for the treatment of dry eye syndrome. Ecabet represents a new class of molecules that increases the quantity and quality of mucin produced by conjunctival goblet cells and corneal epithelia. Mucin is a glycoprotein component of tear film that lubricates while retarding moisture loss from tear evaporation. Ecabet is currently marketed in Japan as an oral agent for treatment of gastric ulcers and gastritis. |
