A simple, accurate, specific and stability-indicating RP-HPLC method was developed for simultaneous determination of chlorzoxazone, diclofenac sodium and paracetamol, using C18 Vydac Monomeric 120A (250 × 4.6mm, 5μ) at 40ºC. The mobile phase contains a mixture of 20mM potassium dihydrogen phosphate buffer (pH 6.2 adjusted with potassium hydroxide) and acetonitrile (30:70 v/v). The flow rate was 1ml/min and detection was carried out at 275nm using PDA detector. The retention time of paracetamol, chlorzoxazone and diclofenac sodium were 3.28mins, 13.27mins and 15.61mins respectively. The analytical curve was linear over a concentration range of 0.65- 6.5μg/ml for paracetamol, 1-10μg/ml for chlorzoxazone and 0.1-1μg/ml for diclofenac sodium. The drugs in bulk and tablet were subjected to acid and alkali hydrolysis, oxidation, thermal and photolytic degradation. This method can be successfully employed for simultaneous quantitative analysis of Chlorzoxazone, Diclofenac sodium and Paracetamol in bulk drug and tablet formulation.

Development And Validation

A new simple, accurate ,precise and reproducible RP-HPLC method has been developed for simultaneous estimation of metformin and pioglitazone in bulk drug form using proper HPLC system. The mobile phase consists of phosphate buffer and acetonitrile in the ratio of 35:65 at pH 3.4.The detection wavelength was carried out at 228 nm. The method was linear over the concentration range for metformin 50-100 μg/mL and for pioglitazone 20-180 μg/mL. The recoveries of metformin and pioglitazone were found to be 100.5 and 98.7% respectively. The validation of method was carried out utilizing ICH-guidelines. The described HPLC method method was successfully for the analysis of pharmaceutical formulations containing dosage form.

Development And Validation

Curcumin is the natural herb that shows effect in the treatment of cancer and rheumatoid arthritis and methotrexate is well known anticancer and anti-rheumatoid drug. Literature survey reveals that there was no method available for the selected drug combination. So, here an attempt has been made to develop simple, rapid and economic method for simultaneous estimation of methotrexate and curcumin in bulk drug by using RP-HPLC method. The percentage assay from optimized method was found to be 99.68% and 99.76% for methotrexate and curcumin respectively.  The proposed method was validated for  linearity, accuracy, precision and robustness according to ICH guidelines and were found to be   within the standard range.

Objective: The present work was focused on the development and validation of reversed-phase high-performance liquid chromatography (RP-HPLC) method which is simple, rapid, precise, accurate, sensitive, economical, and stability-indicating for the quantification of rosuvastatin (RSV) calcium and clopidogrel bisulfate (CLO) in bulk and tablet formulation. Methods: The separation was attained on RP Princeton (C18) column with dimensions (250 mm × 4.6 mm, 5 μ) employing buffer which is a mixture of water (pH 3.0, adjusted with orthophosphoric acid), and methanol in the ratio (20:80) v/v as mobile phase, at flow rate 1.0 ml/min and detection was carried out at wavelength 240 nm. The retention time under the optimized condition of RSV calcium and CLO was found to be 2.844 min and 4.388 min, respectively. Results: The linearity of the method was demonstrated in the concentration range of 6–16 µg/ml and 45–120 µg/ml for RSV calcium and CLO with a correlation coefficient (r2) of 0.9999 and 0.9996, respectively. The percentage relative standard deviation was ˂2% and percentage recovery was found to be 100.12–101.37% and 99.72–101.09% for RSV calcium and CLO, respectively. Assay of marketed tablet formulation was found to be 98.99% and 99.92%, respectively. Conclusion: The developed RP-HPLC method was found to be simple, specific, sensitive, rapid, linear, accurate, precise, and economical and could be used for regular quality control of RSV calcium and CLO in bulk and tablet formulations.
