| Abstract | Beyond instrumental qualification, proficiency testing is not usually a prerequisite for many analytical procedures, given reliance on a manufacturer’s assay validation coupled with regulatory review and inspection. Given the special features of the dissolution procedure, proficiency testing was put in place initially by pharmaceutical manufacturers and carried on by USP. Proficiency testing is designed to help ensure that execution of a dissolution procedure for solid oral dosage forms adequately supports administrative and legal decisions so that measurements made at different times, by different analysts, or with different methods can be confidently compared. USP has applied metrological principles to aid practitioners in carrying out the dissolution procedure alone and in collaborative studies to facilitate understanding potential sources of variability.The present study aimed to identify key dissolution variables associated with USP Lot P Prednisone Tablets in conjunction with the USP Performance Verification Test (PVT). Using five dissolution test assemblies from different manufacturers, at least four of six analysts determined percents prednisone dissolved on dissolution Apparatus 1 (basket) and Apparatus 2 (paddle) on each assembly. Six replicate experiments were performed on each analyst–assembly combination with a set of six to eight tablets in each experiment.Statistical analysis demonstrated that dissolution test assemblies were the largest factor contributing to dissolution variability. Inherent tablet variability was low, and USP Lot P Prednisone Tablets did not contribute importantly to dissolution variability. Contributions from analyst and analytical procedure also were estimated to be low. |

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.
Ministry of Education, through its National Mission on Education through Information and Communication Technology (NMEICT), has sponsored and funded the National Digital Library of India (NDLI) project.
