A novel, safe, economic and sensitive method of spectrophotometric estimation has been developed using Azeoptropic mixture (water:methanol: 60:40, v/v) for the quantitative determination of Lornoxicam, a practically water-insoluble drug. Hence, Lornoxicam stock solution was prepared in Azeoptropic mixture. Lornoxicam showed maximum absorbance at 383 nm. Beer’s law was obeyed in the concentration range 4-24 mg/mL with regression coefficient of 0.999. The method was validated in terms of linearity (R 2 0.999), precision (CV for intra-day and inter-day was 0.280.68 and 0.12-0.92, respectively), accuracy (98.03-100.59% w/w) and specificity. This method is simple, precise, accurate, sensitive and reproducible and can be used for the routine quality control testing of the marketed formulations.
