A Simple, accurate and highly sensitive spectrophotometric method have been developed for the rapid determination of Ofloxacine (OFX) in pure form and pharmaceutical formulations. The visible spectrophotometric method was based on the formation of a Orange Yellow colored complex between the (OFX) and 2-amino-6- nitrobenzothiazole (ANB) at pH 5.2 and 80±5 ºC in 5 min., and λmax at 440 nm. The effects of analytical parameters on the reported system were investigated. Beer's law was obeyed in the concentration range of 1.80-86.72 μg/mL, with a percentage relative standard deviation not exceed ±2.54 and the molar absorptivity coefficients was 3.952×103 (L/mol.cm). Interferences of the other ingredients and excipients were not observed, the results showed that the developed method with the accuracy and sensitivity highs.
