ON THE CORRECTION OF SYSTEMATIC ERRORS OF ANALYTICAL METHODS USED IN THE CONTENT UNIFORMITY TEST

    Abstract
  • In this paper, the constant and proportional systematic errors of analytical methodsfor the content uniformity test were studied with reference to the accurate analytical method for theassay. Seven monographs of tablets admitted to USP(XXII), Ch P (1985, 1990) and JP(Ⅺ) weretaken as cases in point and the systematic errors of two of them, i.e. digoxin and nitroglycerinetablets, were ascertained by the test of significance. To improve the accuracy of analytical methods forthe content uniformity test, a correction formula more reasonable and convicing than that of USP(XXI,XXII) was proposed, and its theoretical basis described briefly.
