Lornoxicam is a non steroidal anti inflammatory drug (NSAID). Modern spectroscopic methods are very effective and sensitive tool for the qualitative and quantitative analysis of many drugs and the results are well employed in the quality control laboratories of pharmaceutical firm. In the present work, the FTIR and Raman spectra of the drug was recorded in the solid state. The fundamental modes of vibration wereassigned based on the position, shape and relative intensity of the recordedspectra and in correlation with the vibrational bands of structurallyrelated molecules. The stability of the drug under different environmental conditions is one of the quality assurance method undertaken in the pharmaceutical laboratory. By employing FTIR spectral technique the qualityof the drug under various storage conditions has been studied. The assay of the tablet of the title drug was done using UV-visible spectroscopyand compared with the labelled amount.
