Abstract With the increased number of multi-drug formulations, there is a need to develop new methods for simultaneous determinations of drugs. A precise, accurate and reliable liquid chromatographic method was developed for simultaneous determination of paracetamol, thiamine, and pyridoxal phosphate in pharmaceutical formulations. Separation of analytes was carried out with an Agilent Poroshell C18 column. A mixture of ammonium phosphate buffer (pH = 3.0), acetonitrile and methanol in the ratio of 86:7:7 (V/V/V) was used as the mobile phase pumped at a flow rate of 1.8 mL min−1. Detection of all three components, impurities and degradation products was performed at the selected wavelength of 270 nm. The developed method was validated in terms of linearity, specificity, precision, accuracy, LOD and LOQ as per ICH guidelines. Linearity of the developed method was found in the range 17.5–30 µg mL−1 for thiamine, 35–60 µg mL−1 for pyridoxal phosphate and 87.5–150 µg mL−1 for paracetamol. The coefficient of determination was ≥ 0.9981 for all three analytes. The proposed HPLC method was found to be simple and reliable for the routine simultaneous analysis of paracetamol, thiamine and pyridoxal phosphate in tablet formulations. Complete separation of analytes in the presence of degradation products indicated selectivity of the method.

Abstract This paper describes validated HPLC and HPTLC methods for simultaneous determination of alprazolam (ALP) and fluoxetine hydrochloride (FXT) in pure powder and formulation. The HPLC separation was achieved on a Nucleosil C8 column (150 mm length, 4.6 mm id, 5 m particle size) using acetonitrilephosphate buffer pH 5.5 (45 + 55, v/v) as the mobile phase at a flow rate of 1.0 mL/min at ambient temperature. The HPTLC separation was achieved on an aluminum-backed layer of silica gel 60F254 using acetonetolueneammonia (6.0 + 3.5 + 0.5, v/v/v) as the mobile phase. Quantification in the HPLC method was achieved with UV detection at 230 nm over the concentration range 414 g/mL for both drugs, with mean recovery of 99.95 0.38 and 99.85 0.56 for ALP and FXT, respectively. Quantification in the HPTLC method was achieved with UV detection at 230 nm over the concentration range of 4001400 ng/spot for both drugs, with mean recovery of 99.32 0.45 and 99.78 0.81 for ALP and FXT, respectively. These methods are simple, precise, and sensitive, and they are applicable for the simultaneous determination of ALP and FXT in pure powder and formulations.

The present work described a simple, rapid, sensitive, accurate, and precise method for simultaneous determination of chlorpheniramine maleate (CHRM) and prednisolone acetate (PRED) in injection samples by high-performance liquid chromatography (HPLC) coupled with UV–Vis detection. Chromatographic separation was accomplished, employing isocratic mode and a mobile phase comprised of acetonitrile and a phosphate buffer (50:50, v/v, 30 °C), adjusted to pH 3.0. The flow rate used was 1.0 mL/min on a Thermo Hypersil ODS C18 column (5 μm, 4.6 × 250 mm), and the injection volume of sample was 20 μL. Analysis of CHRM and PRED was performed at a wavelength of 254 nm. The runtime for analysis was 12.5 min, and the retention times of CHRM and PRED were found to be 2.81 and 5.07 min, respectively. The calibration graph showed linearity over the concentration range 10–70 μg/mL for CHRM and 20–140 μg/mL for PRED with a coefficient of determination (R2) ≥0.9986. Repeatability and reproducibility (expressed as % RSD) were lower than 1.72 and 1.47%, respectively. The proposed HPLC method was demonstrated to be simple and rapid for the determination of CHRM and PRED in injection formulation, providing recoveries between 101.6–102.3%, whereas complete separation of degradation products, from analyte under investigation, provided the specificity of the proposed HPLC method.
