The applicability of a quality by design (QbD) approach for the development of a sensitive and selective stability indicating reversed-phase high performance liquid chromatography (RP-HPLC) method for the estimation of Ivabradine and Metoprolol was investigated. Design of experiments using a fractional factorial design approach was used for method development. Fifteen experimental runs were performed to optimize the chromatographic conditions like mobile phase, flow rate and column oven temperature. Mobile phase composition was optimized by changing Acetonitrile composition ranging between 13 and 17% v/v, Flow rate from 0.6 to 1.0 ml/min and temperature between 30 to 50 0C. The optimized method produced sharp peaks with good resolution (>2) for Metoprolol and Ivabradine with retention times of 3.3 and 9.2 min, respectively. The experimental data revealed that volume of Acetonitrile in mobile phase was prominently affecting the Retention time, Resolution & tailing factor of both the drugs. Normal probability plots revealed that the residual and predicted data fall approximately on a straight line, indicating that the experimental error for these studies was evenly distributed suggesting that the model could be used to navigate the design space. This approach is useful to expedite method development and optimization activities in analytical laboratories.

Abstract A simple, precise, and rapid stability-indicating reversed-phase column liquid chromatographic (RP-LC) method has been developed and subsequently validated for simultaneous estimation of simvastatin (SIM) and ezetimibe (EZE) from their combination drug product. The proposed RP-LC method utilizes a LiChrospher 100 C18, 5 m, 250 4.0 mm id column at ambient temperature; optimum mobile phase consisting of acetonitrilewatermethanol (60 + 25 + 15, v/v/v) with apparent pH adjusted to 4.0 0.1; mobile phase flow rate of 1.5 mL/min; and ultraviolet detection at 238 nm. SIM, EZE, and their combination drug product were exposed to thermal, photolytic, hydrolytic, and oxidative stress conditions, and the stressed samples were analyzed by the proposed method. There were no other coeluting, interfering peaks from excipients, impurities, or degradation products due to variable stress conditions, and the method is specific for the estimation of SIM and EZE in the presence of degradation products. The described method was linear over the range of 180 and 380 g/mL for SIM and EZE, respectively. The mean recoveries were 99.17 and 100.43 for SIM and EZE, respectively. The intermediate precision data were obtained under different experimental conditions, and the calculated value of the coefficient of variation was found to be less than the critical value. The proposed method can be useful in the quality control of bulk manufacturing and pharmaceutical dosage forms.

The current study presents the simultaneous quantification of dexpanthenol and resorcinol from marketed hair care formulation. Dexpanthenol is often present as an active ingredient in personal care products for its beautifying and invigorating properties and restorative and smoothing properties. On the other hand resorcinol is mainly prescribed for the treatment of seborrheic dermatitis of scalp. The toxic side effects of resorcinol limit its use in dermatological preparations. Therefore an accurate quantification technique for the simultaneous estimation of these two components can be helpful for the formulation industries for the accurate analysis of their product quality. In the current study a high performance liquid chromatographic technique has been developed using a C18 column and a mobile phase consisting of phosphate buffer of pH = 2.8 following a gradient elution. The mobile phase flow rate was 0.6 mL per minute and the detection wavelength was 210 nm for dexpanthenol and 280 nm for resorcinol. The linearity study was carried out using five solutions having concentrations ranging between 10.34 μg·mL−1and 82.69 μg·mL−1(r2=0.999) for resorcinol and 10.44 μg·mL−1and 83.50 μg·mL−1(r2=0.998) for dexpanthenol. The method has been validated as per ICH Q2(R1) guidelines. The ease of single step sample preparation, accuracy, and precision (intraday and interday) study presents the method suitable for the simultaneous quantification of dexpanthenol and resorcinol from any personal care product and dermatological preparations containing these two ingredients.

Abstract A simple, rapid, and reliable ultra-performance LC assay method has been developed for the simultaneous estimation of orally administered hypertension drugs (atenolol, hydrochlorothiazide, amlodipine besylate, indapamide, nifedipine, and lercanidipine hydrochloride), any of which may be administered with atenolol in combined hypertension therapy. Chromatography was carried out at 25°C on a 2.1 × 50 mm id, 1.7 μm particle size Acquity BEH C18 column with the isocratic mobile phase 0.01 M, 4.0 pH aqueous phosphate buffer–acetonitrile (50 + 50, v/v) at a flow rate of 0.35 mL/min. All drugs were separated in less than 4 min with good resolution and minimal tailing, without interference by excipients. The method was validated according to International Conference on Harmonization guidelines, and the acceptance criteria for accuracy, precision, linearity, specificity, and system suitability were met in all cases. The column effluent was monitored at 230 nm. The detector response was linear in the range of 1–20 μg/mL of these drugs. LOD obtained was 0.04 μg/mL for atenolol, 0.02 μg/mL for hydrochlorothiazide, 0.03 μg/mL for amlodipine besylate, 0.03 μg/mL for indapamide, 0.02 μg/mL for nifedipine, and 0.01 μg/mL for lercanidipine hydrochloride. The suggested method has the advantage that all the drugs can be quantified alone or in combination with atenolol using a single mobile phase.

A simple, accurate and precise stability indicating method was developed for the simultaneous estimation of the encorafenib (ECRB) and binimetinib (BMTB) in a dosage form by UPLC. Chromatographic elution was processed through a HSS C18 (100 x 2.1 mm, 1.8m) reverse phase column and the mobile phase composition of 0.01N KH2PO4 buffer (3.5 pH) and acetonitrile in the proportion of 55:45 was processed thru a column at a flow rate of 1.0 ml/min. Temperature of the column oven was kept at 30.0°C and the wavelength maximum of detection system was set to 294 nm. Retention times of ECRB and BMTB were found to be 0.767 min and 1.130 min respectively. Repeatability of the method was determined in the form of %RSD and findings were 0.3 and 0.6 for ECRB and BMTB respectively. The percentage recovery of the method was found to be 99.59% and 99.70% for ECRB and BMTB respectively. LOD, LOQ values obtained from regression equations of ECRB and BMTB were 0.51, 1.55mg/ml and 1.47, 4.44 mg/ml respectively. Regression equation of ECRB was y = 6684.x + 18102 and BMTB was y = 13118x + 2159. Two analytes were subjected for acid, peroxide, photolytic, alkali, neutral and thermal degradation studies and the results shown that the percentage of degradation was found between 0.76% and 6.88%. Retention times and total run time of two drugs were decreased and the developed method was simple and economical. So, the developed method can be adopted in industries as a regular quality control test for the quantification of ECRB and BMTB.

The current analytical exploration illustrated developing a reversed-phase high-performance liquid chromatography (RP-HPLC) technique and consequent substantiation for analyzing lamotrigine (LAM) active pharmaceutical ingredient (API) using a Quality-by-design (QbD) approach (Central Composite Design), in bulk product as well as in the tablet formulations. In this experiment, based on systematic scouting, four key components (viz., mobile phase, column, flow-rate, and wavelength) were studied by the RP-HPLC method. 13 experimental runs were done with acetonitrile (ACN) (40-60% v/v) having flow-rate in the range 0.8 mL/min to 1.2 mL/min. The proposed analytical method was thoroughly corroborated in terms of ruggedness linearity, robustness, accuracy, and precision in accordance with ICH guideline Q2A and ICH guideline Q2B. Under the optimum chromatographic environment; Intersil C8 column of 250 mm length, 4.6 mm (i.d.); 20 μL injection volume; and mobile phase ACN: Methanol (60:40 v/v), a retention time of 2.542 min was noticed at 220 nm detection wavelength. The method was found to be extremely reproducible, accurate, linear, precise, robust, and economically adequate to execute the estimation. The intended analytical technique was thoroughly assessed through statistical tools and could be an imperative concern for the habitual scrutiny of LAM in bulk products and its formulation.
