| Abstract | A simple, rapid, and selective method to determine the concentration of ziprasidone hydrochloride in schizophrenics’ plasma using ultra performance liquid chromatography-tandem mass spectrometry (UPLC-MS-MS) was developed and validated. The UPLC separation was carried out with an Acquity UPLC BEH C18 column (50 × 2.1 mm i.d., 1.7 μm particle size). The mobile phase consisted of methanol–water (50:50, v/v; the water included 15 mM NH4Ac and 0.125% acetic acid). The detection was performed on a triple-quadrupole tandem mass spectrometer by multiple reaction monitoring (MRM) mode via electrospray ionization (ESI) at m/z 412.82 → 193.75 for ziprasidone and m/z 236.87 → 193.76 for the internal standard, carbamazepine. Solid-phase extraction was used to extract ziprasidone hydrochloride and carbamazepine from plasma. Ziprasidone and the internal standard eluted as sharp, symmetrical peaks with retention times of 1.24 ± 0.01 min and 1.74 ± 0.02 min, respectively. Calibration curves of ziprasidone at concentrations ranging from 0.7 to 400 ng mL−1 exhibited excellent linearity (r = 0.9995), with a lower limit of quantification of 0.7 ng mL−1. Intra- and inter-day relative standard deviations were less than 7.75% RSD and 5.43% RSD, respectively. The extraction recovery was above 81.3%. The described assay method showed acceptable precision, accuracy, linearity, stability, and specificity and can be used for pharmacokinetic studies. |

National Digital Library of India (NDLI) is a virtual repository of learning resources which is not just a repository with search/browse facilities but provides a host of services for the learner community. It is sponsored and mentored by Ministry of Education, Government of India, through its National Mission on Education through Information and Communication Technology (NMEICT). Filtered and federated searching is employed to facilitate focused searching so that learners can find the right resource with least effort and in minimum time. NDLI provides user group-specific services such as Examination Preparatory for School and College students and job aspirants. Services for Researchers and general learners are also provided. NDLI is designed to hold content of any language and provides interface support for 10 most widely used Indian languages. It is built to provide support for all academic levels including researchers and life-long learners, all disciplines, all popular forms of access devices and differently-abled learners. It is designed to enable people to learn and prepare from best practices from all over the world and to facilitate researchers to perform inter-linked exploration from multiple sources. It is developed, operated and maintained from Indian Institute of Technology Kharagpur.
