Identification
A:
The retention time of the sucrose octasulfate peak in the chromatogram of theAssay preparation corresponds to that in the chromatogram of theStandard preparation,as obtained in theAssay.
B:
Shake a portion of finely powdered Tablets,equivalent to about 1g of sucralfate,with 3Nhydrochloric acid,and filter:the solution so obtained meets the requirements of
Identification test
Cunder
Sucralfate.
Acid-neutralizing capacity
Weigh and finely powder not fewer than 20Tablets.Transfer an accurately weighed portion of the powder,equivalent to about 250mg of sucralfate,to a 250-mLscrew-capped bottle,and proceed as directed in the test for
