Preparation of famotidine pills and content of the dissolution study
Amount of goods , made to match with the flow containing 0.2mg per lml of the solution ,[link widoczny dla zalogowanych], shake,[link widoczny dla zalogowanych], that is, too . Preparation of the test solution of 20 pills to take for the test materials , and research uniform, accurately weighed amount (equivalent to famotidine 20mg), set 100ml flask,[link widoczny dla zalogowanych], add the mobile phase dissolved and diluted to volume, filtered , as for Test solution. According to high performance liquid chromatography (China Volume II Appendix VD) determined the precise amount of solution of 20l, high performance liquid chromatograph , record the chromatogram , according to external standard method with peak area calculation,[link widoczny dla zalogowanych], which was shown in Table 11 . Table 11 Results of determination of famotidine pills 5 Conclusion and discussion paper on the basis of a large number of tests designed prescriptions , and the dissolution of famotidine pills and drug content were examined.
