Validação de metodologia analítica de matéria-prima de meloxicam por espectrofotometria UV-vis

Abstract

Meloxicam is an anti-inflammatory, which acts on pain relief and reduced inflammation due to diseases on joints such as rheumatoid arthritis and osteoarthritis. In order to have the desired effect, the drug used in manufacturing needs to comply the necessary quality, thus, chemical and microbiological analyses must be performed for. Recently, British Pharmacopoeia and United States Pharmacopoeia official compendia advocate potentiometric analysis and liquid chromatography, respectively toanalyze the assay of the drug meloxicam, other pharmacopoeias consultely ‘ have no existing method. In order to obtain an alternative method, it was pursued to develop and validate a method by spectrophotometry UV-vis. The method used sodium hydroxide 0.1 M, ethanol and water as diluents. The maximum wavelength found on was 355nm, which was used on readings for this solution. The validated method attained specificity, linearity, range, repeatability, accuracy and robustness.”
