Atropine sulfate 25Mg
Appropriate amount of excipients

prepared 1000 tablets


trait

This product is white tablet.


identification

In the chromatograms recorded under the content determination of diphenoxylate hydrochloride and atropine sulfate, the retention time of the main peak of the test solution should be consistent with the retention time of the main peak of the control solution.


examination

  • Content uniformity diphenoxylate hydrochloride take 1 tablet of this product, put it in a mortar, grind it finely, add the appropriate amount of mobile phase under the item of diphenoxylate hydrochloride content determination, grind it, and transfer the mobile phase to a 50ml measuring flask in portions, shake to dissolve diphenoxylate hydrochloride, dilute to the scale with mobile phase, shake well, filter, and take the filtrate to determine the content of diphenoxylate hydrochloride by the method under the item of determination of diphenoxylate hydrochloride, which shall comply with the regulations (General rule 0941)..
  • atropine sulfate take 1 tablet of this product, put it in mortar, grind it finely, add the appropriate amount of mobile phase under atropine sulfate content determination, grind it, and transfer the mobile phase to 25ml measuring flask in fractions, shake to dissolve atropine sulfate, dilute to scale with mobile phase, shake well, filter, take filtrate 50 u1, determine according to the method under the content determination of atropine sulfate; in addition, take an appropriate amount of atropine sulfate reference substance, weigh it precisely, add the mobile phase to dissolve and quantitatively dilute it to make a solution containing about 1 ml per 1 ml, and determine with the same method, calculate with peak area according to external standard method, and the limit is ± 20%, the provisions shall be met (General rule 0941).
  • others shall be in accordance with the relevant provisions under the item of tablets (General rule 0101).

Content determination

  • diphenoxylate hydrochloride was measured by HPLC (General 0512).
  • chromatographic conditions and system suitability test using eighteen alkyl silane bonded silica gel as filler; Triethylamine phosphoric acid solution (take triethylamine 4ml, add water 500ml, phosphoric acid 2ml, add water to 1000ml, mix well)-Acetonitrile (45:55), and adjust pH to 3.1±0.2 as mobile phase; Detection wavelength was 230nm. The number of theoretical plates is not less than 2000 based on the peak of diphenoxylate.
  • determination of 50 tablets of this product, precision weighing, fine, precision weighing an appropriate amount (about 2.5mg equivalent to diphenoxylate hydrochloride), put in a 50ml measuring flask, add an appropriate amount of mobile phase, fully shake to dissolve diphenoxylate hydrochloride, dilute to the scale with mobile phase, shake, filter, take the filtrate as the test solution, accurately measure 20ul injection liquid chromatograph, record the chromatogram. Another appropriate amount of diphenoxylate hydrochloride reference substance was accurately weighed, dissolved and quantitatively diluted with mobile phase to make a solution containing about 50ug per 1ml, and the same method was used for determination. According to the external standard method to calculate the peak area, that is.
  • atropine sulfate was measured by high performance liquid chromatography (General 0512).
  • chromatographic conditions and system applicability test using eighteen alkyl silane bonded silica gel as filler; Triethylamine phosphoric acid solution (4ml of triethylamine, 500ml of water, 1.8ml of induced acid, 1000ml of water, mixed with acetonitrile (85:15), and adjust the pH value to 5.8±0.2 as mobile phase; The detection wavelength was 206nm. The number of theoretical plates shall not be less than 3000 calculated from the peak of atropine sulfate.
  • determination Method: Take the above fine powder, weigh appropriately (about 0.5mg of atropine sulfate), put it in a 50ml measuring flask, add appropriate amount of mobile phase, and fully shake to dissolve atropine sulfate, dilute to the scale with mobile phase, shake, filter, take the continued filtrate as the test solution, take the precision of 20u1 injection liquid chromatograph, record the chromatogram. In addition, an appropriate amount of atropine sulfate reference substance was accurately weighed, dissolved and quantitatively diluted with mobile phase to prepare a solution containing about 10ug per lml, and determined by the same method. According to the external standard method, the peak area is calculated, and the result is multiplied by 1.027.
