3-Acetamidobenzene -1, 2-dicarboxylic acid is a potential genotoxic impurity which gets formed during synthesis of 3- acetamidopthalic anhydride, a Key Starting Material (KSM) for manufacturing of apremilast API. During handling upon exposure to moisture, the anhydride ring of KSM 3-acetamidopthalic anhydride opens to form the acid. Hence Reverse phase HPLC method is not a feasible and robust option for estimation of this impurity. To overcome these problems a normal phase HPLC method is developed and proposed in this research work. Immobilized Chiral pack IA column from Daicel is used for estimation. n-Hexane and isopropyl alcohol in 90:10 (v/v) ratio modified with 0.1% trifluroacetic acid is used as mobile phase. Method is validated as per ICH guidelines. Limit of Detection (LOD) and Limit of Quantification (LOQ) are found to be 0.47 ppm (0.0047%) and 1.42 ppm (0.0142%), respectively. The method is linear over LOQ to 150%. Recovery is within limits (80-120%). Method is robust for parameters like mobile phase composition, flow rate, wavelength changes and column oven temperature.

Abstract For the determination of enalapril maleate in tablets a new, simple and economical HPLC method was developed and fully validated. Chromatographic separation was achieved on Hewlett Zorbax SB-C 18 (150 x 4.6 mm, 5 μm) column and the mobile phase consisted of acetonitrile: 0.025 M phosphate buffer adjusted to pH 3 (70:30 v/v) pumped at a flow rate 0.8 mL/min and UV-detection was performed at 210 nm. The proposed method was validated according to ICH guidelines (linearity, limit of detection, limit of quantification, precision, accuracy, recovery and system suitability). The total run time was less than 3 min and the retention time for Enalapril maleate was 2.3 min. The calibration graph was linear in the concentration range between 10 – 100 μg/mL with the correlation coefficient r2 = 0.9998. The developed and validated method was successfully applied to determine the Enalapril maleate in tablets. Therefore, this method proved to be sensitive, specific and reproducible and can be applied for routine analysis of enalapril maleate from pharmaceutical formulation due to its simplicity of application.

The Given

In this study, the modified stability-indicating RP-HPLC method was validated for quantitative analysis of amlodipine besylate in the presence of its impurity D (3-ethyl 5-methyl 2-[(2-aminoethoxy)methyl]-4-(2-chlorophenyl)-6-methylpyridine-3,5-dicarboxylate). The method was applied for the determination of an analyte in the tablets and irradiated samples packed in the primary packaging (Alu/PVC/PVDC blister packaging). The efficient chromatographic separation was achieved using a ZORBAX Eclipse XDB-C18 column (4.6×250 mm, 5 mm) with isocratic elution of mobile phase which consisted of acetonitrile:methanol:triethylamine solution (15:35:50, v/v/v) (pH 3.0). The flow rate of the mobile phase was 1 mL min-1, while the detection of amlodipine besylate was carried out at 273 nm. Amlodipine besylate and its impurity D were identified at the retention times of 16.529 min and 2.575 min, respectively. The linearity of the method with the coefficient of determination of 0.999 was confirmed in the concentration range of 10 - 75 µg mL-1 for amlodipine besylate. The limit of detection was 0.2 µg mL-1, while the limit of quantification was 0.66 µg mL-1. After UV and Vis radiation of the tablets packed in the primary packaging, the content of amlodipine besylate was reduced by 22.38% and 19.89%, respectively. The presence of new degradation products was not detected under the given chromatographic conditions. The photodegradation of amlodipine besylate followed pseudo-first-order kinetics. Based on the half-life of amlodipine besylate (38.4 days for UV radiation and 43.3 days for Vis radiation), it was concluded that amlodipine besylate in the tablets has satisfactory photostability after its packing in the Alu/PVC/PVDC blister packaging.

Hplc Technique

The present study aims to develop a simple, accurate and specific stability-indicating RP-HPLC technique for the analysis of metoclopramide in the presence of its stress degradation products and characterization of degradation compounds by LC-MS/MS analysis. As per ICH Q1A-R2 guidelines, the drug was exposed to acid hydrolytic stress condition. Three degradation products were formed for MCP in acid hydrolysis. The liquid chromatography was processed on a Luna C18-(2) 100A,250×4.6mm 5micron column using an isocratic mobile phase consisting of 0.1% formic acid in water-acetonitrile (20:80, v/v) by adjusting the mobile phase at 1 ml/min flow rate with wavelength detection at 273 nm. The developed procedure was applied to LC-MS/MS (liquid chromatography-tandem mass spectrometry) for the characterization of all the degradant components. Total new three degradation compounds were recognized and identified by LC-MS/MS. The developed RP-HPLC technique was validated as per the ICH Q2-R1 guidelines. Limit of detection and limit of quantification values of MCP were evaluated from the linearity graph and were found to be 5.23 µg/ml and 17.44 µg/ml. Accuracy study was established at 80.0, 100.0 and 120.0 µg/ml concentration levels and the findings were found in the range of 98.4% - 101.8%. The linearity of the technique was assessed over the drug concentration range of 50.0 µg/ml to 250.0 µg/ml and the regression equation, slope and correlation coefficient values were found to be y = 10618x + 1623.2, 10618 and 0.9996 respectively. The developed technique was uninterruptedly applied for the quantification of metoclopramide inactive pharmaceuticals.

The Stability

A simple, fast, and validated HPLC method was developed for the simultaneous quantization of five cardiovascular agents: dopamine (DPM), dobutamine (DBM), phentolamine (PTM), furosemide (FSM), and aminophylline (APL) either in infusion samples or in an injection dosage form. The proposed method was achieved with a 150 mm × 4.6 mm, 5.0 μm C18 column, by using a simple linear gradient. Mobile phase A was buffer (50 mM KH2PO4) and mobile Phase B was acetonitrile at a flow rate of 1.0 mL/min. The column temperature was kept at 30°C, and the injection volume was 20 μL. All analytes were separated simultaneously at a retention time (tr) of 3.93, 5.84, 7.06, 8.76, and 9.67 min for DPM, DBM, PTM, FSM, and APL, respectively, with a total run time of less than 15.0 min. The proposed method was validated according to ICH guidelines with respect to accuracy, precision, linearity, limit of detection, limit of quantitation, and robustness. Linearity was obtained over a concentration range of 12.0–240.0, 12.0–240.0, 20.0–200.0, 6.0–240.0, and 10.0–200.0 μg/mL DPM, DBM, PTM, FSM, and APL, respectively. Interday and intraday accuracy and precision data were recorded in the acceptable limits. The new method has successfully been applied for quantification of all five drugs in their injection dosage form, infusion samples, and for evaluation of the stability of investigated drugs in mixtures for endovenous use. The results of the stability study showed that mixtures of DPM, DBM, PTM, FSM, and APL in 5% glucose or 0.9% sodium chloride injection were stable for 48 hours when stored in polypropylene syringes at 25°C.

The advancements in analytical techniques have enabled the development of highly sensitive and accurate methods for the identification of materials up to trace levels using microliter of sample. A highly sensitive and novel GC-FID method has been developed and reported herein for the simultaneous quantification of paracetamol (PCM) and caffeine (CAF) in samples up to trace levels. The method was validated as per ICH guidelines for its sensitivity, linearity, robustness, inter and intra-day variations, limit of quantification (LOQ), limit of detection (LOD), matrix effect, carryover, precision, and accuracy. The LOD of PCM and CAF were determined to be 100 ppm and 10 ppm whereas, LOQ of PCM and CAF were found to be 300 and 30 ppm respectively. The method was applied to quantify PCM and CAF in marketed tablets and dissolution samples of the tablets, which showed highly precise and accurate quantification of PCM and CAF. Moreover, the GC-FID method was compared with reported HPLC method which suggested the superiority of GC-FID method in performance and sensitivity. In short, the newly developed GC-FID method showed sensitivity and selectivity for PCM and CAF estimation and can be adopted as an efficient method for various applications.
