A novel RP-HPLC method was developed and validated for the determination of compounds in an oral solution. The method describes the determination of domperidone along with sodium methylparaben, sodium propylparaben and sodium benzoate in liquid oral formulation. Chromatographic separations were performed using BDS Hypersil 5 μm C18 column and gradient elution (solvent A: phosphate buffer, pH 3.5 and solvent B: methanol), keeping a flow rate of 1.5 mL/min. Detection was done at dual wavelength (232 nm for domperidone and sodium benzoate, and 257 nm for sodium methylparaben and sodium propylparaben). Analysis time was <17 min. The retention times for domperidone, sodium benzoate, sodium methylparaben and sodium propylparaben were found to be 10.0, 6.5, 8.0, and 13.5 min., respectively. The calibration curves for domperidone, sodium benzoate, sodium methylparaben and sodium propylparaben were found to be linear in the range of 250-750, 50-150, 50-150, and 5-15 μg/mL.

Due to the low absorptivity of bile acids, the aim of this study was to develop and validate a simple and sensitive HPLC/UV method for quantification of ursodeoxycholic acid (UDCA) in pharmaceutical formulations. Effective separation was achieved on C18 end–capped column, with gradient elution of a mobile phase composed of 0.001 M phosphate buffer (pH 2.8±0.5) – acetonitrile mix, at flow rate 1.5 mL min-1, UV detection at 200 nm and injection volumes were 50 µL. The proposed HPLC method was fully validated according to the ICH guidelines and it was found to be simple, accurate, precise and robust.

Key Variables

A highly specific, accurate, and simple RP-HPLC technique was developed for the real-time quantification of domperidone (DOMP) and lansoprazole (LANS) in commercial formulations. Chromatographic studies were performed using a Luna C8(2), 5 μm, 100Å, column (250 × 4.6 mm, Phenomenex) with a mobile phase composed of acetonitrile/2 mM ammonium acetate (51:49 v/v), pH 6.7. The flow rate was 1 mL·min−1 with UV detection at 289 nm. Linearity was observed within the range of 4–36 µg·mL−1 for domperidone and 2–18 µg·mL−1 for lansoprazole. Method optimization was achieved using Box-Behnken design software, in which three key variables were examined, namely, the flow rate (A), the composition of the mobile phase (B), and the pH (C). The retention time (Y1 and Y3) and the peak area (Y2 and Y4) were taken as the response parameters. We observed that slight alterations in the mobile phase and the flow rate influenced the outcome, whereas the pH exerted no effect. Method validation featured various ICH parameters including linearity, limit of detection (LOD), accuracy, precision, ruggedness, robustness, stability, and system suitability. This method is potentially useful for the analysis of commercial formulations and laboratory preparations.

Background: Omeprazole has poor water solubility, is unstable in acidic solutions, and undergoes first pass metabolism which results in lowering its bioavailability. A solid Self-Nano Emulsifying Drug Delivery System (SNEDDS) was previously prepared to enhance its dissolution. Objective: Development and validation of a RP-HPLC method with UV detection for the determination of omeprazole in 0.1N HCl and in 0.01 M phosphate buffer (pH 7.4). Methods: Validation was according to the ICH Q2 (R1) guidelines in terms of linearity, accuracy and precision, lower limit of quantification, sensitivity, specificity, and robustness. The developed and validated method was used to study the in-vitro dissolution of the drug from the solid-SNEDDS, commercial products and of the unprocessed drug. The dissolution was studied in 500 ml of 0.1N HCl during the first 2 hours, and 900 mL of 0.01 M phosphate buffer (pH 7.4) during the last hour (37 ± 0.5 oC and 100 rpm). Results: The method was linear in the range 1-50 μg/ml, accurate and precise as indicated by the ANOVA test. It was specific to the drug and the pharmaceutical excipients did not affect the determination of its concentration. The method was robust to small changes in pH, composition, and flow rate of the mobile phase. The dissolution rate of omeprazole from the Solid-SNEDDS was faster than that from two commercial dosage forms and than the dissolution rate of the unprocessed drug. Conclusion: The method met the acceptance criteria and was applied successfully in studying the rate of dissolution of the drug.

In this article we describe development and validation of stability indicating, accurate, specific, precise and simple Ion-pairing RP-HPLC method for simultaneous determination of paracetamol and cetirizine HCl along with preservatives i.e. propylparaben, and methylparaben in pharmaceutical dosage forms of oral solution and in serum. Acetonitrile: Buffer: Sulfuric Acid (45:55:0.3 v/v/v) was the mobile phase at flow rate 1.0 mL min-1 using a Hibar® Lichrosorb® C18 column and monitored at wavelength of 230nm. The averages of absolute and relative recoveries were found to be 99.3%, 99.5%, 99.8% and 98.7% with correlation coefficient of 0.9977, 0.9998, 0.9984, and 0.9997 for cetirizine HCl, paracetamol, methylparaben and Propylparaben respectively. The limit of quantification and limit of detection were in range of 0.3 to 2.7 ng mL-1 and 0.1 to 0.8 ng mL-1 respectively. Under stress conditions of acidic, basic, oxidative, and thermal degradation, maximum degradation was observed in basic and oxidative stress where a significant impact was observed while all drugs were found almost stable in the other conditions. The developed method was validated in accordance with ICH and AOAC guidelines. The proposed method was successfully applied to quantify amount of paracetamol, cetirizine HCl and two most common microbial preservatives in bulk, dosage form and physiological fluid.

A reversed phase high performance liquid chromatographic (RP–HPLC) method was developed and subsequently validated for the determination of atomoxetine hydrochloride in bulk and pharmaceutical formulation. The separation was done by a PerkinElmer Brownlee analytical C8 column (260 mm x 4.6 mm, 5 µm) using methanol: 50 mM KH2PO2buffer (PH adjusted to 6.8 with 0.1 M NaOH), 80:20 v/v as an eluent. UV detection was performed at 270 nm at a flow rate 1.0 mL/min. The validation of the method was performed, and specificity, reproducibility, precision accuracy and ruggedness were confirmed. The correlation coefficient was found to be 0.997 for atomoxetine hydrochloride. The recovery was in the range of 99.94 to 100.98% and limit of quantification was found to be 5.707 µg/mL. The method is simple, rapid, selective and economical too and can be used for the routine analysis of drug in pharmaceutical formulations.
