Abstract A new chiral reversed-phase (RP)-HPLC method with UV detection was developed. Enantioselective resolution of ibuprofen (IBP) was achieved using (3R,4S)-4-(3,5-dinitrobenzamido)-3-(3-(trioxysilyl)-propyl)-1,2,3,4-tetrahydro-phenanthrene [(R,R)-Whelk-O2] chiral stationary phase (4.6 mm id × 250 mm, 10 μm) with a mobile phase composed of ethanol–water (30 + 70, v/v) containing 100 mM ammonium acetate at a flow rate of 1.3 mL/min using diode array detector at λ 220 nm. Calibration curves were linear over the concentration range of 20–180 μg/mL for both IBP enantiomers. Mean % recoveries ±SD of 99.74 ± 1.73 and 99.60 ± 0.93 were obtained for dexibuprofen (dex-IBP) and levoibuprofen (levo-IBP), respectively. Intra- and interday precision calculated as RSD, % were not more than 1.66% for dex-IBP and 1.93% for levo-IBP. The detection limits were 2.09 and 2.06 μg/mL for dex-IBP and levo-IBP, respectively. The method was successfully applied for the determination of dex-IBP in tablet dosage form.

A reversed-phase high-pressure liquid chromatography (RP-HPLC) method was developed and subsequently validated for the simultaneous determination of butamirate citrate (BC) and benzoic acid (BA) in cough syrup. The separation was performed employing a cyanopropyl column with a mobile phase consisting of 50%/50% v/v MeOH/NaH2PO4 * H2O 50 mM aqueous solution pH = 3.0. The quantitation was achieved with a diode array detector (DAD) at 210 nm. The method demonstrated a congenitally satisfactory separation, yet the acquired peaks were asymmetrical. This effect was eliminated by using 1% triethylamine in the buffer solution as a silanol blocker. In addition, the method was found to unequivocally assess the target analytes in the sample matrix and fulfilled the required specifications in relevance to specificity, linearity, accuracy, precision and stability of both the standard solutions and of the sample solutions. Lastly, an experimental design was designed in order to assess the robustness of the proposed assay. To this purpose, a graphical and a statistical approach were utilized and compared to identify the factors that should be strictly controlled during each execution of the method.

A novel reversed-phase high performance liquid chromatographic (HPLC) technique for the determination of everolimus (Isomer-B) and its impurities in the tablet dosage form has been optimized using analytical quality by design (QbD) approach. All the compounds are monitored with the photodiode array (PDA) detector at 280 nm and the parameters namely; precision, accuracy, specificity, stability, linearity, limit of quantitation (LOQ) and limit of detection (LOD) are evaluated. The quantitation limits of IMP-A, IMP-B, IMP-C, IMP-D, IMP-E, Sirolimus and TGR are found to be 0.08, 0.08, 0.10, 0.10, 0.10, 0.08 and 0.08, respectively. Recovery studies from 0.9 mg/L to 9.0 mg/L are performed for all impurities and the values were obtained between 85-110 %. Injection volume and test concentrations have been optimized to achieve LOQ values under the reporting threshold. The whole technique is developed and validated as per International Council for Harmonization (ICH) guidelines. The proposed method is robust, sensitive, rapid and successful and helpful in the regions where regulatory agencies recommend HPLC analytical method.

A simple, selective and rapid reversed phase high performance liquid chromatographic (RPHPLC) method for the analysis of atenolol and amlodipine in tablet has been developed and validated. The chromatographic system consisted of a LC-20 AT pump, SPD-20 A UV/visible detector. The separation was achieved from C18 column at ambient temperature with a mobile phase consisting of methanol-acetonitrile buffer (solution of ammonium acetate and sodium pentanesulphonate ratio, 55:10:35 v/v, PH=3.00 adjusted with phosphoric acid) at a flow rate of 1ml/min and the retention time was about 1.67 minutes for atenolol and 5.0 minutes for amlodipine. The method is selective and able to resolve drug peaks from formulation excipients. The peaks of atenolol and amlodipine were well separated (resolution 11.65). The calibration curves were linear over the concentration range of 80% to 120% (r2 = 0.999 for both the drugs). The proposed method is accurate with 100.72% recovery for atenolol and 99.44% recovery for amlodipine and precise (%RSD of intra day variation were 0.53-0.152 for atenolol and 0.067-1.518 for amlodipine and %RSD of inter day variation were 0.024-1.518 for atenolol and 0.034-1.518 for amlodipine). The method has been used to test market products (six brands) and potency was found within limit (99.02%- 100.02% for atenolol and 97.4%-100.4% for amlodipine). Therefore, this method can be used as a more convenient and efficient option for the analysis of atenolol and amlodipine in tablet dosage form.

A simple, fast, accurate and precise reverse phase HPLC method is developed and described for the determination of ramelteon in tablet dosage form. Chromatography was carried on an ODS column using a mixture of acetonitrile and phosphate buffer pH 7.0 (35:65 V/V) as the mobile phase at a flow rate of 1.0 mL/min with detection at 286 nm. The retention time of the drug was 7.7 min. The procedure was validated for linearity, precision, accuracy, and robustness. The developed method was validated for linearity from 50 to 150% which shows the method is quite linear with a correlation coefficient of 0.999, for precision which includes system precision, method precision, intraday and by another analyst on another day, and accuracy. The %RSD for system precision was observed to be 1.1, whereas the method precision was observed to be 0.2. The % recovery from ‘accuracy’ studies yielded the recovery of 99.7-101.5% which indicates the capability of the method, and finally for robustness that includes studies w.r.t. change in flow rate, the percentage of organic modifier and pH. As per ICH guidelines, method validation results are in good agreement. The proposed method was simple, sensitive, precise and accurate.
