RESUMO
OBJECTIVE: To prepare methazolamide eye drops and establish its quality control method.METHODS: Methazolamide eye drops was prepared using inorganic nanoparticles as carrier and methazolamide as principal agent.The content of methazolamide was determined by ultraviolet spectrophotometry.The stability of the preparation was investigated. RESULTS: The preparation was white suspension andin conformity with the description ofChina Pharmacopeia(2005 edition) inidentification and test.The linear concentration range of methazolamide was4~12?g.mL-1(r=0.999 9) and the average recovery was100.10% (RSD=1.11%).Methazolamide eye drops was unstable under highlight , while all the test items had no significant change in6-month accelerated test.CONCLUSION: The preparative method is si mple and feasible and the quality of the preparationis stable and controllable.But the preparation should be stored away formlight.
