Description
Curator's Comment:: Description was created based on several sources, including http://www.santeninc.com/newsroom/press-releases/10_04_DIQUAS.pdf | http://www.santen.com/en/therapeutic-areas/asia/dryeye/diquas/

Diquafosol, a dinucleotide Up4U, is an agonist for purinergic P2Y2 receptor. Diquafosol stimulated water and mucin secretion by acting on P2Y2 receptors on the conjunctival epithelial and goblet cell membrane and elevating intracellular calcium ion concentrations. The Japanese Ministry of Health, Labour and Welfare granted approval for DIQUAS Ophthalmic Solution 3% (diquafosol tetrasodium) for the treatment of dry eye.

Sample Use Guides

DIQUAS Ophthalmic Solution 3% (generic name: diquafosol tetrasodium). Usually, instill 1 drop a time 6 times daily.
Route of Administration: Topical
3% diquafosol tetrasodium had a significant, time-dependent, inhibitory effect on human corneal epithelial cells (HCEC) proliferation and cytotoxicity. HCECs treated with diquafosol detached more from the bottoms of dishes and damaged cells showed degenerative changes, such as, reduced numbers of microvilli, vacuole formation, and chromatin of the nuclear remnant condensed along the nuclear periphery.
