CHAPTER 3 LITERATURE REVIEW
Ravi Sharma,et,al., A simple reverse phase liquid Chromatographic method has been developed and subsequently validated for simultaneous determination of Pioglitazone and Glimepiride in combination. The separation was carried out using a mobile phase of phosphate buffer (pH-4.5): Acetonitrile (45:55) v/v and using methanol as diluent. The column used was Inertsil ODS (250 mm x 4.6 mm i.d., 5μm) with flow rate of 1 ml/min using UV detection at 225 nm. The described method was linear over a concentration range of 5-50µg/ml and 5-25 µg/ml for the assay of Pioglitazone and Glimepiride respectively. The retention times of Pioglitazone and Glimepiride were found to be4.6 and 7.7min respectively. Results of analysis were validated statistically and by recovery studies. The results of the study showed that the proposed RP-HPLC method is simple, rapid, precise and accurate, which is useful for the routine determination of Pioglitazone and Glimepiride bulk drug and in its pharmaceutical dosage form.
Sujatha Samala,et.al.,
A simple and sensitive reverse phase high performance liquid chromatography (RP-HPLC) method was developed for the determination of glimepiride in rat serum. The assay involves one step liquid-liquid extraction with methanol. Gliclazide was used as an internal standard. Chromatographic separation was performed on a C18 column using a
