By mixing the first solution and the second solution prepared above, the composition of Example 16 having a pH of about 7.2 ⁇ 0.2 was prepared.
  • Example 16 evaluation of irritation was performed. After administering 30 ⁇ L of the composition of Example 16 to both eyes of 23 healthy adults, a burning sensation, a foreign body sensation, blurred vision, and residual sensation felt after 6 hours for 3 minutes were evaluated according to the criteria in Table 19.
  • Table 20 shows the average values of the evaluation scores. As a result of the evaluation, burning sensation, foreign body feeling, blurred vision, and residual feeling were not felt or appeared to be insignificant, indicating that the ophthalmic composition of the present invention has very excellent ocular feeling (Table 20).
  • Example 17 was prepared according to the composition of Table 21 below.
  • Example 17 Xanthan gum was added to sterile purified water, hydrated at a high temperature (60 to 70° C. or higher), and dissolved by adding polyethylene glycol, followed by high-temperature and high-pressure sterilization to prepare a first solution. Separately, polyvinyl alcohol is added to sterilized purified water and dissolved at a high temperature (60 ⁇ 70 °C or higher), then dexpanthenol, polysorbate, buffer and diquafosol sodium are dissolved, filtered through a 0.2 ⁇ m membrane filter, and the second solution was prepared. By mixing the first solution and the second solution prepared above, the composition of Example 17 having a pH of about 7.2 ⁇ 0.2 was prepared.
  • the composition of Example 17 according to the present invention maintains a constant viscosity even at a shear rate of about 3000 S ⁇ 1 , whereas the Diquas ophthalmic solution has a constant viscosity at a shear rate of about 900 S ⁇ 1 It was confirmed that it could not be maintained. In addition, it was confirmed that the composition of Example 17 exhibits high viscosity even at a minimum shear rate of 1000 S -1 or higher due to a general blink.
  • Example 17 After mixing the composition of Example 17 with a STF (Simulated Tear Fluid) solution in a ratio of 30:7, the shear rate at regular time intervals is changed from 1 S -1 to 5000 S -1 to 5000 S again. While changing from -1 to 1 S -1 , the viscosity was measured at 35° C., and the results are shown in FIG. 10 .
  • STF Simulated Tear Fluid
  • Example 17 As can be seen from FIG. 10 , it was confirmed that the instantaneously dropped viscosity at a high shear rate was quickly and completely recovered in the composition of Example 17 according to the present invention. Accordingly, it can be seen that the eye drop composition of the present invention maintains excellent and continuous viscosity even under shear stress such as eye blinking.
