Gatifloxacin shows maximum absorbance at 333 nm. Beer's law was obeyed in the concentration range of 10 to 60 ¦Ìg/ml, N N- di methyl urea does not absorb above 260 nm. Commonly used tablet excipients and N, N- di methyl urea did not interfere in spectrophotometric estimation. Results of the analysis were validated statistically and by recovery studies. Using 7.5 M N, N- di methyl urea solution for analysis of two different tablet formulations of Gatifloxacin , the percent label claims and percent recoveries estimated were close to 100 with low values of standard deviation, percent coefficient of variation and standard error. %K Gatifloxacin %K hydrotropy %K N %K N- di methyl urea %K spectrophotometry %U http://jgpt.co.in/jgpt/index.php/jgptjournal/article/view/100
