Abstract:
Objective:To investigate the feasibility and accuracy of osmometer in the osmolarity measurement of pirenoxinun sodi-um eye drops. Methods:An osmometer was used to measure the osmolarity of pirenoxinun sodium eye drops, and the stability of the osmolality was studied. Results:The osmolarity of pirenoxinun sodium eye drops with different formula conformed to the requirement of ophthalmic preparations. The osmolality showed no significant change at the ambient temperature, indicating the stability of the prepa-ration. Conclusion:The method is simple, rapid and practical, which can be used as the osmolarity measurement method for pirenoxi-nun sodium eye drops.
