Embodiment

[0101] The results of pharmacological tests and preparation examples are shown below, but these examples are for better understanding of the present invention and do not limit the scope of the present invention.

[0102] [test 1]

[0103] Normal male white rabbits were used to evaluate changes over time in the amount of tears after instilling the present composition.

[0104] (drug preparation method)

[0105] Eye drops 1:

[0106] According to the prescription table shown in Table 1, eye drop 1 (in Table 1, the unit is g / 100mL) was prepared. That is, diquafosol sodium (9 g), sodium hydrogen phosphate hydrate (0.6 g), edetate sodium hydrate (0.03 g) and sodium chloride (1.35 g) were dissolved in sterilized purified water to obtain 50 mL of 6 times thick liquid. In addition, after mixing 10 mL of the 6-fold concentrated solution and 5 mL of sterilized purified water, PVP K30 (1.2 g) was dissolved, and then, a pH adjuster was added appropriately to adjust the pH to 7, and 20...

Abstract

Provided is an ophthalmic composition containing diquafosol or a salt thereof, a vinyl-based polymer and a cellulose-based polymer. Also provided is an agent for preventing or treating dry eyes, which contains diquafosol or a salt thereof, a vinyl-based polymer and a cellulose-based polymer. These aqueous dissolution type eye drops for treating dry eye contain 3% (w / v) of diquafosol sodium, hydroxyethyl cellulose and polyvinylpyrrolidone having a K value of 30, and are characterized in that 1-2 drops are administered to the eyes three times per day.

Description

technical field [0001] The present invention relates to an ophthalmic composition containing diquafosol or a salt thereof, a vinyl-based polymer, and a cellulose-based polymer. Background technique [0002] Diquafosol is also known as P 1 ,P 4 - Diquafosol sodium as its salt as "DIQUAS (注册商标) Eye Drops 3%" (hereinafter also referred to as "DIQUAS (注册商标) eye drops") for the treatment of dry eye syndrome (Japanese Patent No. 3651707 (Patent Document 1), DIQUAS ( 注册商标) 3% Drug Instructions for Eye Drops (Non-Patent Document 1)). On the other hand, DIQUAS ( 注册商标 ) The usage and dosage of the eye drops is usually 6 times a day, 1 drop each time, and the eyes are instilled (Non-Patent Document 1). However, it is difficult to regularly and frequently instill eye drops in daily life, so there are patients who cannot obtain the expected effect due to poor eye instillation compliance. [0003] As an attempt to search for a new dry eye treatment agent having a higher tear volume...
