subsequently assayed by the proposed method. The
mean percentage added recovery using regression
equation was found to be 100.64±1.2.
The repeatability and reproducibility of the method
were carried out using 200 and 150µg/ml tranexamic acid,
respectively. The mean percentage recovery of four
replicate analyses was found to be 99.99±0.86 and
100.01±0.94, respectively.
The proposed method was applied to the
determination of tranexamic acid in capsules labeled to
contain 250mg. The mean content percent of four
independent analyses was found to be 101.13±1.04.
Statistical analysis of the results, obtained by an
adopted B.P formal titration method for assay of
tranexamic acid injection [24] and the proposed method
using t-test and F-test [23], showed no significant
difference between the performance of the two methods
regarding the accuracy and precision (Table 4).
