The MS/MS transitions were <em>m/z</em> 330.2 → 142.0 for BCQB and <em>m/z</em> 344.2 → 156.1 for the I. S in positive ESI mode.</p> <p><strong>Results: </strong>The validated method was linear over the concentration range of 2-1200 pg/ml with the correlation coefficient <em>r<sup>2</sup></em>&gt;0.998. The intra-and inter-batch precisions of the assay were lower than 8.2% and 9.1%, respectively. The lower limit of quantification (LLOQ) was 2 pg/ml. The stability data at different storage conditions of BCQB were within±5% RE. The mean <em>AUC</em><sub>0-36</sub> of BCQB was increased by approximately 33%, after the administration of BCQB alone and upon co-administration with paroxetine during the drug interaction study.</p> <p><strong>Conclusion: </strong>The LC-MS/MS method validated in this study was robust, reproducible, accurate, precise and reliable and was successfully applied in the pharmacokinetic drug interaction studies.</p> 2021-10-01T00:00:00+0530 Copyright (c) 2021 JANVIER ENGELBERT AGBOKPONTO, LOCONON ACHILLE YEMOA, ASSOGBA GABIN ASSANHOU, RUIJUAN LIU, HABIB GANFON, LI DING IN VITRO ASSESSMENT OF PHYSICOCHEMICAL PARAMETERS OF FIVE GENERICS AMLODIPINE BESYLATE TABLETS MARKETED IN YEMEN 2021-08-18T00:43:30+0530 ARWA ALSHARGABI <p><strong>Objective: </strong>The present paper aims to evaluate the quality of five different brands (local and imported) of oral film-coated tablets of generic Amlodipine besylate 5 mg marketed in Sana`a-Yemen, through physiochemical parameters. </p> <p><strong>Methods: </strong>Different physicochemical parameters including the uniformity of tablet weight, hardness, thickness, disintegration time, and an assay of active ingredients were conducted to validate the quality of generics Amlodipine Besylate 5 mg according to USP specification.</p> <p><strong>Results: </strong>From the obtained results, it was observed that all the brands of Amlodipine Besylate 5 mg have passed the tests and met the specifications of USP. Results of weight variation, hardness, thickness, and disintegration time were ranged from -3.8 % to + 5.13 % to -1.25 % to +3.25 %, 5.06 ± 0.31 to 13.21 ± 1.5, 2.682 ± 0.04 to 3.676 ± 0.01 and 25 s to 2 min:30 s, respectively. The dissolution test and the assay results of all the brands are also ranged within the acceptable label claim 93.7 ± 2.24 to 98.4 ± 0.85 and 93.22 ± 0.38 to 100.15 ± 0.33, respectively. However, there is no relation was found between the disintegration time and the dissolution test.</p> <p><strong>Conclusion: </strong>According to the finding, all the selected Amlodipine Besylate 5 mg brands are met pharmacopeia standards and USP specifications. Therefore, the local and imported Amlodipine Besylate 5 mg can be used safely to get the desired therapeutic efficiency.</p> 2021-10-04T00:00:00+0530 Copyright (c) 2021 ARWA ALSHARGABI ESTIMATION OF RESIDUAL SOLVENTS IN NETUPITANT API BY HEADSPACE GAS CHROMATOGRAPHY 2021-07-29T06:48:28+0530 SUNNY GRACE GODE VIJAYA LAKSHMI G. <p><strong>Objective: </strong>Residual solvents are undesirable components present in Active Pharmaceutical Ingredients (API), excipients, or drug products. To meet the specific quality-based requirements, the presence of these solvents in pharmaceutical products should be monitored to ensure their safety. The main objective of this work is to develop a new method for the determination of residual solvents in netupitant API by an HS-GC method with an FID detector.</p> <p><strong>Methods: </strong>An automated headspace GC method has been developed and validated for the estimation of the residual solvents- N-methyl pyrrolidine, xylene, toluene, and N, N Dimethylacetamide in netupitant API. The samples were dissolved in dimethyl sulfoxide and</p> <p>the equilibrium headspace gas was formed at 80℃ which was analyzed using a DB-624</p> <p>column (30m*0.53mm, 3.00µm) with injector and detector temperature set at 160℃ and 230℃ respectively. The initial oven temperature was set at 60℃ for 5mins and programmed at a rate of 10℃/min to the final temperature of 150℃, with a hold time of 5mins by maintaining the flow rate of 4.0ml/min with a split ratio of 1:10, and total run time of 20mins. Nitrogen was used as carrier gas. The method developed was validated as per International Conference for Harmonization (ICH) guidelines for repeatability, linearity, range, ruggedness, detection limit, quantification limit, and recovery studies.</p> <p><strong>Results: </strong>The linearity range selected was 50-350µg/ml and the correlation coefficient(γ<sup>2</sup>) values for all the solvents were found to be &gt;0.99; recovery studies values were in a range of 90-110% and %RSD values were also found to be not more than 10 for the solvents.</p> <p><strong>Conclusion: </strong>A novel, accurate, sensitive, and simple method was described for estimating residual solvents in Netupitant API by Headspace Gas Chromatography (HS-GC) coupled with a Flame Ionization Detector (FID). Excellent results have been observed for all the validated parameters with good peak resolution and lesser retention times.</p> 2021-09-17T00:00:00+0530 Copyright (c) 2021 SUNNY GRACE GODE, VIJAYA LAKSHMI G.
