Development And Validation

A stability indicating reverse phase HPLC method was developed for the determination of metaxalone, a skeletal muscle relaxant, present in bulk and its pharmaceutical formulations using gliclazide as the internal standard (I.S). A hypersil ODS C18 column (250 × 4.6 mm, packed with 5 micron) in an isocratic mode with mobile phase Acetonitrile: phosphate buffer 3.6 (50:50%v/v) was used at a flow rate of 0.8 mL/ min and effluent was monitored at 225 nm. The assay exhibited a linear dynamic range of 0.6-100 µg/mL. Acceptable precision and accuracy were obtained for concentrations over the standard curve range. The retention times were 5.13 min and 9.08 min for metaxalone and IS respectively. The extraction recovery of metaxalone from pharmaceutical dosage form (tablets) was >97% and the calibration curve was linear (r2= 0.999) over the entire linear range. The method had an accuracy of >98% and LOD and LOQ of 0.2 µg/mL and 0.6 µg/mL respectively. The specificity of the proposed method was performed whereby metaxalone undergoes different stress conditions like oxidation, reduction, photolysis, acid and alkaline hydrolysis.

First Time

This study reports for the first time about a stability indicating RP-HPLC method for analysis of darolutamide and its impurities 1, 2, and 3 in bulk and formulations. The separation was achieved on Phenomenex column with Luna C18 (250 mm × 4.6 mm, 5 μm) as stationary phase, and 50 mM ammonium acetate: methanol solution 15:80 (v/v) at pH 5.2 as mobile phase at 1.0 mL/min flow rate. UV detection was carried at wavelength of 239 nm. In these conditions the retention time of darolutamide and its impurities 1, 2, and 3 was 7.05, 8.90, 4.63 and 5.95 min, respectively. The method was validated for system suitability, range of analysis, precision, specificity, stability, and robustness. Forced degradation study was done through exposure of the analyte to five different stress conditions and the % degradation was small in all degradation condition. The proposed method can separate and estimate the drug and its impurities in pharmaceutical formulations. Hence, the developed method was suitable for the quantification of darolutamide and can separate and analyse impurities 1, 2, and 3

Liquid Chromatographic

Midostaurin is a multi-targeted protein kinase inhibitor that has been used for the treatment of acute myeloid leukemia.  Here, a rapid and precise reverse phase high-performance liquid chromatographic method has been developed for the validation of midostaurin, in its API form as well as in capsule dosage form. Chromatography was carried out on a X-Bridge C18 (4.6 x 250 mm, 5 µm) column using a mixture of methanol: water (75:25% v/v) as the mobile phase at a flow rate of 1.0 mL/min, the detection was carried out at 243nm and the retention time of the midostaurin was found to be 3.155. The method produce linear responses in the concentration range of 10-50 µg/mL of midostaurin. The method precision for the determination of assay was below 2.0 % RSD. The LOD and LOQ values obtained were 1.2 µg/mL and 3.8 µg/mL respectively. There were no significant changes observed upon changing chromatographic conditions indicating the method to be robust. Therefore this validated method can be useful in the quality control of bulk and pharmaceutical formulations of midostaurin.

In this work, ELS-Detector has been used for the development of an HPLC method for the determination of clarithromycin in pharmaceutical formulations (tablets and pediatric suspension). Isocratic reversed phase HPLC approach has been developed using a C-18 column (Waters Spherisorb 5 μm ODS2, 4.6x250 mm) and a mobile phase consisting of acetonitrile / aqueous trifluoroacetic acid as pairing reagent. Experimental parameters (temperature of heated drift tube, flow rate of mobile phase, gas flow rate, mobile phase composition) were optimized. Clarithromycin’ s stability was thoroughly examined in different solvent systems. Using the optimized conditions the working range was 5-100 μg/mL (upper limit can be increased considerably), with a detection limit of 4.5 μg/mL (6x10-6 M). The method was validated as per ICH guidelines. The retention time was 4.7 min. The method was successfully applied for the content assay of clarithromycin formulations.

A simple, rapid, precise and accurate method is developed for the quantitative simultaneous determination of ceftriaxone and tazobactum in bulk and pharmaceutical formulations. Separation of ceftriaxone and tazobactum was successfully achieved by using Inertsil C18 ODS column 250X4.6mm, 5µm in an isocratic mode using water and acetonitrile (80:20) at a flow rate of 1.0 ml/min and was monitored at 254 nm with a retention time of 3.049 minutes and 4.317 minutes for ceftriaxone and tazobactum respectively. The method was validated and the response was found to be linear in the drug concentration range of 20µg/ml to 80 µg/ml for ceftriaxone and 5 µg/ml to 35 µg/ml for tazobactum. The values of the correlation coefficient were found to be 0.999 for ceftriaxone and 0.999 for tazobactum respectively. The LOD and LOQ for ceftriaxone were found to be 0.021 and 0.064 respectively. The LOD and LOQ for tazobactum were found to be 0.030 and 0.091 respectively. The percentage recovery for ceftriaxone and tazobactum were found to be 98-102% respectively which indicates that the proposed method is highly accurate. The specificity of the method shows good correlation between retention times of standard with the sample. The method was extensively validated according to ICH guidelines for Linearity, Accuracy, Precision, Specificity and Robustness.  Stability of the drugs was determined by using acid/base, thermal, oxidative stress testing.

Abstract A method is described for the simultaneous determination of paracetamol, tizanidine, and diclofenac in mixtures. The method was based on HPLC separation of the three drugs followed by UV detection at 254 nm. The separation was carried out on a Hypersil ODS, C18 (250 × 4.6 mm id, 10 μm particle size) column using the mobile phase aqueous 0.2% ammonium carbonate–methanol (60 + 40, v/v) at a flow rate of 1 mL/min. The linear regression analysis data were used for the regression curve in the range of 170–10,000 ng/mL for paracetamol, 120–10,000 ng/mL for tizanidine, and 20–10,000 ng/mL for diclofenac. No chromatographic interference from tablet excipients was found. In order to check the selectivity of the proposed method, degradation studies were carried out using hydrolysis (acid, basic, and neutral), thermolysis, and oxidation. The developed method, after being validated in terms of precision, robustness, recovery, LOD, and LOQ, was successively applied to the analysis of pharmaceutical formulations and human serum.

Objective: The present study deals with the development, validation and application of a simple, precise and accurate HPLC method for the determination of mycophenolate mofetil in pharmaceutical formulations and microemulsions. Methods: In this method, a simple isocratic mobile phase composition of methanol and water (75:25 v/v) pumped at 1 ml/minute flow rate through Phenomenex C18 column (dimension: 250 4.6 mm and 5 µm particle size) was used. Injection volume was 20 µl and analysis of mycophenolate mofetil was carried out at 250 nm. Results: The coefficient of regression was found to be 0.9996, indicating the linearity of the developed method within a range of 0.1 to 10 µg/ml. The limit of detection (LOD) and the limit of quantization (LOQ) were found to be 3.660ng/ml and 11.091ng/ml, respectively. The results showed that % deviation for change in compositions of the mobile phase, flow rate and temperature was within a range of-5.51 to 10.99%,-3.70 to 8.80% and-5.29 to 10.90%, respectively. The method seemed sensitive to change of temperature (±5 ○C) and methanol composition (±2%) as the results were at the boundary limit of 10% deviation. Conclusion: A simple, precise and accurate HPLC method for the determination of drug content from microemulsion has been developed and validated in accordance with ICH guidelines.
