A simple, rapid, accurate and precise RP-HPLC method was developed and validated for the determination of fenpiverinium bromide and pitofenone HCl. Separation of the drug was achieved on a reverse phase Thermo Kromasil C18 Column. The method showed a linear response for concentration in the range of 1.2-2.8μg/ml for FVB 6-14 μg/ml for PFH using diammonium hydrogen orthophosphatee buffer pH 7.2: acetonitrile as the mobile phase in the ratio of 55:45, v/v with detection at 220 nm with a flow rate of 1 ml/min and retention time was 3.77min and 7.45 min for FVB and PFH respectively. The method was statistically validated for linearity, accuracy, precision and selectivity.The limit of detection and limit of quantitation was 0.0654 µg/ml and 0.1982 µg/ml for FVB and 0.0927 µg/ml and 0.281 µg/ml for PFH, respectively. In quantitative and recovery studies, % RSD was found less than 2. Due to simplicity, rapidity and accuracy of the method, we believe that the method will be useful for routine quality control analysis of fenpiverinium bromide and pitofenone HCl in pharmaceutical formulations.

A novel and simultaneous stability indicating RP-HPLC method has been developed for quantitative analysis of bumetanide in fixed dose pharmaceutical formulations. Bumetanide and its degradation products are well separated by the Discovery C18, 250 × 4.6 mm, 5 μm column as a stationary phase and (50:50 v/v) of 0.1 % o-phthalaldehyde and acetonitrile as a mobile phase. All the compounds are monitored using photodiode array detector at 254 nm with an isocratic method and the flow rate of 1.0 mL/min was maintained. Validation of method was performed as per International Council for Harmonization (ICH) guidelines and the parameters namely; precision, accuracy, specificity, stability, robustness, linearity, limit of quantitation (LOQ) and limit of detection (LOD) were evaluated. The linearity of the proposed method was found to be 0.315-1.875 μg/mL for bumetanide and its impurities. The developed method is more economical and suitable for laboratory use because of solvent consumption is very less. Hence, the developed method can be used for the determination of bumetanide and its impurities in drug product stability studies and pharmaceutical formulations.

This article refers to simple isocratic reverse-phase high-performance liquid chromatographic method (RP-HPLC) developed for the simultaneous quantification of Escitalopram Oxalate (EST) and Clonazepam (CZP) in active pharmaceutical ingredient and pharmaceuticals. The separation of the two drugs was attained using a C₁₈ column (250mm×4.6mm, 5µ) as a stationary phase. The mobile phase was used as a mixture of methanol; acetonitrile; and 0.05M potassium dihydrogen orthophosphate buffer (pH 4 adjusted by orthophosphoric acid) with an isocratic ratio of 40:20:40 v/v. Detection was made by using PDA detector at 210 nm. Escitalopram Oxalate (RT= 4.428 minutes) and Clonazepam (RT= 6.532 minutes) were separated in a single chromatographic run with resolution of 8.719. The calibration plot indicated good linear relationship with r2 = 0.998 for Escitalopram Oxalate in concentration range of 32 µg/ml - 48 µg/ml and r2 = 0.999 for Clonazepam in concentration range of 16 µg/ml - 24 µg/ml. The retrievals for Escitalopram Oxalate and Clonazepam were found to be 99.75% and 99.00%, respectively. The established analytical method was validated and found acceptable as per ICH guidelines for linearity, precision, accuracy, specificity, limit of detection, limit of quantification, robustness and stability. Escitalopram Oxalate and Clonazepam individually as well as in combination were exposed to different stress conditions like acid, base, thermal, photolytic and oxidation degradation and peaks of a degraded product were well determined from peaks of pure drug. This method is modest, quick and appropriate for routine quality control analysis. Keywords: Reverse Phase – HPLC; Escitalopram Oxalate; Clonazepam; Validation; Degradation study.
