Diquafosol tetrasodium was approved by Pharmaceuticals Medical Devices Agency of Japan (PMDA) on April 16, 2010. It was developed and marketed as Diquas® by Santen Pharmaceutical Corporation in Japan.

Diquafosol tetrasodium is a P2Y2 purinoceptor receptor agonist. It is indicated for improve dry eye symptoms by promoting secretion of mucin and water, thereby bringing the tear film closer to a normal state. No serious ocular or systemic adverse drug reactions were found during the clinical trials. Dry eye begins with symptoms of ocular discomfort such as burning, stinging or a foreign body sensation.

Diquas® is available as solution for ophthalmic use, containing 3% of Diquafosol tetrasodium. The recommended dose is 1 drop at a time, 6 times a day.

Index:

Diquafosol (tradename Diquas) is a pharmaceutical drug for the treatment of dry eye disease. It was approved for use in Japan in 2010.[1] It is formulated as a 3% ophthalmic solution of the tetrasodium salt.

Its mechanism of action involves agonism of the P2Y2 purinogenic receptor.[2]

A scalable and practical route to synthesize the P2Y2 receptor agonist diquafosol tetrasodium has been described. Diquafosol tetrasodium was obtained via a four-step process starting from commercially available 5′-uridylic acid disodium salt. The whole procedure gives the target product in a 45% overall yield with high purity (>99%). Key steps in this process including isolation of impurities and the target product by using anion-exchange resin are discussed in detail. The optimized process has been successfully demonstrated on a large scale to support the development of diquafosol tetrasodium in China.
