| Abstract | A sensitive and specific LC–MS-MS method is described for the simultaneous quantification of risperidone and 9-hydroxyrisperidone in human plasma. After extraction with tert-butyl methyl ether, plasma samples were separated on an Atlantis HILIC Silica C18 column (4.6 × 150 mm, 5 μm)with a mobile phase of ammonium formate buffer (10 mM, pH 4.0)/acetonitrile (40/60, v/v). Detection was by MS-MS. The method was fully validated according to the accuracy profile theory. It is based on β-expectation tolerance interval for the total measurement error which includes trueness and intermediate precision. The measurement uncertainty derived from β-expectation tolerance interval was estimated at each of the validation standards. The linearity fitted well over the range of 0.11–26.75 ng mL−1 for risperidone with an LLOQ of 0.11 ng mL−1, and for 9-hydroxyrisperidone, at a range of 0.15–37.8 ng mL−1 with an LLOQ of 0.15 ng mL−1. The intra- and inter-batch precision of risperidone were <5.71 and 8.22%, respectively. For 9-hydroxyrisperidone, the data were 5.78 and 6.48%. The recoveries were 88.78% (risperidone) and 70.35% (9-hydroxyrisperidone). The developed method was applied to a pharmacokinetic study of risperidone. |

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.

NDLI is a conglomeration of freely available or institutionally contributed or donated or publisher managed contents. Almost all these contents are hosted and accessed from respective sources. The responsibility for authenticity, relevance, completeness, accuracy, reliability and suitability of these contents rests with the respective organization and NDLI has no responsibility or liability for these. Every effort is made to keep the NDLI portal up and running smoothly unless there are some unavoidable technical issues.
