Doxycycline is a broad spectrum antibiotic used in the treatment of infectious diseases in humans and animals. It is distributed free of charge, by medical prescription, in Brazil through the public health system. Thus, since a considerable number of people have access to this drug, it is of great interest to control its quality. The purpose of the research was the development and validation of an eco-friendly method by Fourier-Transform Infrared (FT-IR) transmission spectroscopy for the determination of doxycycline in raw material. The raw material quality directly determines the quality of the drug. Through this analysis the method was completely validated according to the International Conference on Harmonization guidelines, showing accuracy, precision, selectivity, robustness and linearity. It was linear over the concentration range of 0.5 – 2.5 mg with correlation coefficient 0.9991 and limits of detection and quantification of 0.125 and 0.378 mg, respectively. Fourier-Transform Infrared (FT-IR) transmission spectroscopy method is considered environmentally friendly because it uses only the potassium bromide as reagent, which is cheap and safe for the operator, does not expose the operator to toxic solvents or harmful reagents, and optimizes equipment for being a rapid analysis. The validated method is useful to the routine quality control of doxycycline.
