abstract
Results: The Raman technique allowed us to elucidate the functional groups of the pioglitazone hydrochloride and the HPLC technique was linear, accurate, precise, specific and sensitive in the range of 30 to 2,000 ng/mL under the chromatographic conditions specified.Conclusions: The structure analysis by Raman spectroscopy allowed us a complete characterization of the functional groups of pioglitazone hydrochloride effectively and non-destructively. Likewise, the analytical technique for the pioglitazone hydrochloride quantification by HPLC was linear, accurate, precise and sensitive in the range of 30 to 2,000 ng/mL under the guidelines.Introduction: The thiazolidinediones (pioglitazone) increases the action of insulin and produces the glycemie control in the patients with type 2 diabetes mellitus. Also, the pharmacological effect may be affected by the purity and pioglitazone plasma concentration. Therefore, the instrumental techniques offer a tool for characterization, identification and/or quantification of the pioglitazone; Raman spectroscopy offers several advantages due to its easy application methodology and structural analysis and the HPLC technique is the gold standard vs. other qualitative and quantitative techniques.Objective. The aim of this work is to develop and validate analytical techniques for the characterization of pioglitazone hydrochloride by Raman spectroscopy and quantitative analysis in human plasma by HPLC.Material and methods: The pioglitazone hydrochloride was analyzed by Raman spectroscopy with a 678 mW power and 3 integration time seconds. The analytical method for quantification by HPLC was validated with the guidelines of the NOM-177SSA1-1998.
