Development and validation of UV spectrophotometry and liquid chromatography methods for determination of cefpirome in raw material and pharmaceutical dosage
In the present work, analytical methods, UV Spectrophotometry and Liquid Chromatography (HPLC), were developed and validated for quantification of cefpirome, a broad-spectrum fourth-generation cephalosporin, in raw material and powder for injectable preparation. The UV spectrophotometric method was...

| Sumario: | In the present work, analytical methods, UV Spectrophotometry and Liquid Chromatography (HPLC), were developed and validated for quantification of cefpirome, a broad-spectrum fourth-generation cephalosporin, in raw material and powder for injectable preparation. The UV spectrophotometric method was performed at 271 nm, using 0.1 M hydrochloric acid as solvent. The HPLC was carried out using Techsphere ODS column and mobile phase consisted of methanol-water (30:70, v/v) with flow rate 0.8 mL/min and UV detection at 265 nm. The validation method yielded good results demonstrated statistically that the methods were linear, precise, accurate, specific and robust. A preliminary stability study of cefpirome showed that the UV Spectrophotometry and Liquid Chromatography methods were specific for the determination cefpirome in the presence of its degradation products. No statistically difference was observed between the proposed methods. The UV Spectrophotometry and Liquid Chromatography methods allow the quantitation of cefpirome in pharmaceutical dosage form and raw material and can be used for the drug analysis in routine quality control. |
