Interaction study is the most important step in reformulation study for the preparation of all dosage forms. The interaction can affect physical, chemical, therapeutic and biological properties and stability of drug and create a new surprise problem, the successful formulation of stable and effective solid dosage form depends on the careful and suitable choice of excipient. Also the selection of excipient is vital in the design of a quality drug product. The quality of medicine depends not only on the active principals and productions process, but also on the performance of the excipients .The present work shows the interaction study of Lornoxicam and polymers for Nano products. In IR the interaction of infrared radiation with matter. It covers range of techniques, mostly based on absorption spectroscopy. DSC is a thermo-analytical technique in which the difference in the amount of heat required to increase the temperature of sample and reference is measured as a function of temperature.
