Abstract:In this study, we developed a cheap and precise analytic method to measure Etodolac concentration in bulk and pharmaceutical formula. The modified, updated method depends on the reaction between ferric ion and Etodolac to yield ferrous ion. Then the former ion reacted with potassium ferric cyanide to form colored compound has a maximum absorbance at 700 nm. The method was validated by calculating the precision and accuracy. The method follows Beer-Lamber law so that we used the range between 1-22.5 µg/mL and t… Show more
