An isocratic high-performance liquid chromatographic method using electrochemical detection (HPLC-ECD) for the quantitation of clarithromycin (CLA) was developed using Response Surface Methodology (RSM) based on a Central Composite Design (CCD). The method was validated using International Conference on Harmonization (ICH) guidelines with an analytical run time of 20 min. Method re-validation following a change in analytical column was successful in reducing the analytical run time to 13 min, decreasing solvent consumption thus facilitating environmental and financial sustainability. The applicability of using the United States Pharmacopeia (USP) method scaling approach in place of method re-validation using a column with a different L–designation to the original analytical column, was investigated. The scaled method met all USP system suitability requirements for resolution, tailing factor and % relative standard deviation (RSD). The re-validated and scaled method was successfully used to resolve CLA from manufacturing excipients in commercially available dosage forms. Although USP method scaling is only permitted for columns within the same L-designation, these data suggest that it may also be applicable to columns of different designation.

A new high performance liquid chromatographic (HPLC) method was developed for the determination of paracetamol, phenylephrine hydrochloride, oxolamine citrate and chlorpheniramine maleate in combined pharmaceutical formulations and dosage forms. The separation was performed on an Agilent Zorbax SB-CN column with the mobile phase consisting of 0.02 M phosphate buffer (pH:4) and acetonitrile (85:15,v/v) in flow rate 1.5 mL at 22 °C. The overall retention time of the analytes was 3.5 min. The method was validated with respect to linearity, precision, accuracy and recovery. The relative standard deviation for 10 replicate measurements of paracetamol, phenylephrine HCl, oxolamine citrate and chlorpheniramine maleate were 0.12, 0.36 0.18 and 0.59%, respectively. Total recoveries of analytes were 99.99, 100.56, 100.20 and 99.60%, respectively. No chromatographic interference from the tablet excipients was found. The linearity of paracetamol, phenylephrine HCl, oxolamine citrate and chlorpheniramine maleate were in the range of 20-120 μg/mL, 0.4-2.4 μg/mL, 8-48 μg/mL and 0.16-0.96 μg/mL, respectively. This simple, fast, economical and precise high performance liquid chromatographic method can be adopted for routine quality control analysis.

A selective and sensitive reverse phase High Performance Liquid Chromatographic method has been developed and validated for the estimation of lornoxicam in bulk, pharmaceutical dosage forms and in dissolution samples. The analysis was performed isocratically on an Inertsil column (250* 4.6 mm, 5 µm) using a mass spectrometric compatible mobile phase of 10 mM ammonium acetate: acetonitrile (50:50 V/V) at a flow rate of 1 mL/min.The detection wavelength was 290 nm. The retention time was found to be 4.573 min for lornoxicam. The linearity of the method has been satisfied with Beer Lambert’s law in the concentration range of 5-25 µg/mL with a correlation coefficient of 0.9988. The mean recoveries assessed for lornoxicam were in the range of 100.39-101.86 %, indicating good accuracy of the method. The limit of detection and limit of quantification were found to be 0.03 and 0.11 µg/mL, respectively. The developed method has been statistically validated in accordance with ICH guidelines and found to be mass spectrometric compatible, simple, precise, and accurate with the prescribed values. Thus, the proposed method was successfully applied for the estimation of lornoxicam in routine quality control analysis of bulk, formulations and in dissolution samples.

Abstract A simple, precise, and accurate isocratic reversed-phase (RP) stability-indicating column high-performance liquid chromatographic (HPLC) assay method was developed and validated for determination of nebivolol in solid pharmaceutical dosage forms. Isocratic RP-HPLC separation was achieved on a Phenomenex Luna C8 (2) column (250 mm 4.6 mm id, 5 m particle size) using mobile phase composed of acetonitrilepH 3.5 phosphate buffer (35 + 65, v/v) at a flow rate of 1.0 mL/min, and detection was performed at 280 nm using a photodiode array detector. The drug was subjected to oxidation, hydrolysis, photolysis, and heat to apply stress conditions. The method was validated for specificity, linearity, precision, accuracy, robustness, and solution stability. The method was linear in the drug concentration range of 40160 g/mL with a correlation coefficient of 0.9999. The repeatability relative standard deviation (RSD) for 6 samples was 0.69, and the intermediate precision (RSD) for 6 samples was 1.39. The accuracy (recovery) was between 98.57 and 99.55. Degradation products produced as a result of stress studies did not interfere with detection of nebivolol, and the assay can thus be considered stability-indicating.

A simple, selective, linear, precise and accurate isocratic RP-HPLC method was developed and validated for rapid assay of Vandetanib, an anticancer drug, in both bulk and tablet dosage form. Elution at a flow rate of 1ml/min was employed on a symmetry C18 column at ambient temperature. The mobile phase consisted of acetonitrile, water and orthophosphoric acid in the ratio of 90:08:02 (v/v/v). Linearity was observed in concentration range of 50-200 ppm. The retention time for Vandetanib was 3.326 min. The method was validated as per the ICH guidelines. The proposed method can be successfully applied for the estimation of Vandetanib in pharmaceutical dosage forms. Moreover the detection alone was also verified through LC-MS of the Vandetanib drug using ESI method which provides future scope for study of this drug using LC-MS method also.
