Analytical Data: Beer’s law was found to be valid over
the tranexamic acid concentration range 50-250µg/ml.
Linear regression analysis of the data gave the following
equation:
A= -0.1003+3.2985×10 C (R= 0.996). 3
where A is the absorbance in 1cm cell, C is the
concentration of the drug in µg/ml and R is the correlation
coefficient.
Optical characteristics and statistical [23] data for the
regression equation of the proposed method are given in
Table 3.
To test the accuracy of the proposed method a
volume of reference tranexamic acid solution (100µg/ml)
was added to the capsules solution (100µg/ml) and
