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> JANVIER ENGELBERT AGBOKPONTO LOCONON ACHILLE YEMOA ASSOGBA GABIN ASSANHOU RUIJUAN LIU HABIB GANFON LI DING Copyright (c) 2021 JANVIER ENGELBERT AGBOKPONTO, LOCONON ACHILLE YEMOA, ASSOGBA GABIN ASSANHOU, RUIJUAN LIU, HABIB GANFON, LI DING 2021-09-24 2021-09-24 10.22159/ijpps.2021v13i10.5791 ESTIMATION OF RESIDUAL SOLVENTS IN NETUPITANT API BY HEADSPACE GAS CHROMATOGRAPHY <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> SUNNY GRACE GODE VIJAYA LAKSHMI G.

Identification of medical devices, parts of a syringe and intravenous (I.V) infusion set, intramuscular (I.M) injection and intravenous infusion techniques were taught using demonstration and intervention method. Participants were then evaluated for their knowledge by OSPE method using validated checklists. Participants were also asked to give feedback for teaching and evaluation method. Data were analyzed using SPSS 20.0.0, IBM Corporation.</p> <p><strong>Results: </strong>After intervention method 100% participant could identify needle, cannula, and I.V infusion set. Noticeable difference was found in identifying parts of a syringe and IV infusion set after intervention method. OSPE evaluation post-intervention showed that more number of participants could perform the steps of injection correctly and in sequence. OSPE scores post-intervention differed significantly (&lt;0.001) with demonstration method.</p> <p><strong>Conclusion: </strong>Demonstration coupled with the power point teaching method was found better than the demonstration method alone .This method should be used to impart practical knowledge of injection technique.</p> SARITA PANIGRAHY SUNIL KUMAR PANDEY MEHER SHEENA BALA TRIPURA SUNDARI Copyright (c) 2021 SARITA PANIGRAHY, SUNIL KUMAR PANDEY, MEHER SHEENA, BALA TRIPURA SUNDARI 2021-09-17 2021-09-17 10.22159/ijpps.2021v13i11.42756
