<Precautions related to Indications>

This product should be used in patients diagnosed with dry eye, associated with keratoconjunctival epithelium disorders that accompany lacrimal fluid abnormality.

1.Mechanism of Action

Diquafosol sodium stimulated water and mucin secretion by acting on P2Y2 receptors on the conjunctival epithelial and goblet cell membrane and elevating intracellular calcium ion concentrations.

2.Stimulatory action on secretion of tear fluid including mucin

1) A single-dose administration of diquafosol sodium into the eyes of normal animals (rabbits and rats) promoted tear fluid secretion and mucin secretion from the conjunctival cells.

2) A single-dose administration of diquafosol sodium into the eyes of dry eye model rats promoted tear fluid secretion. Repeated dose administration increased mucin contents in the conjunctival tissues.

3.Improvement of corneal epithelial damage

Repeated dose administration of diquafosol sodium 6 times daily for 4 weeks improved corneal epithelial damage in rat dry eye model in a dose-dependent manner. It exhibited the maximal effect at the concentration of 1% or higher. The repeated dose of 1% diquafosol sodium for 2 weeks exhibited the maximal improvement effect when daily administration exceeded 6 times.
