|Abstract||A controlled release dosage form of theophylline in the form of microspheres using the milk protein casein as the matrix is described. Glutaraldehyde cross-linking of an aqueous alkaline solution of the protein containing the drug, dispersed in a mixture of dichloromethane/hexane having ca. 1% of an aliphatic polyurethane as the suspension stabilizer, led to the formation of the drug-loaded microspheres. Drug incorporation efficiency of around 80% could be achieved by the technique. Release profiles of the drug were examined in simulated gastric and intestinal fluids at 37 degrees C. It was observed that the release was diffusion-controlled and followed the Higuchi model. Release characteristics were influenced by the cross-linking density, particle size and the extent of loading. Data obtained indicate that the natural milk protein casein could be used as a matrix for sustained release oral dosage forms.|

Ministry of Human Resource Development (MHRD) under its National Mission on Education through Information and Communication Technology (NMEICT) has initiated the National Digital Library of India (NDLI) project to develop a framework of virtual repository of learning resources with a single-window search facility. Filtered and federated searching is employed to facilitate focused searching so that learners can find out the right resource with least effort and in minimum time. NDLI is designed to hold content of any language and provides interface support for leading vernacular languages, (currently Hindi, Bengali and several other languages are available). It is designed 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 being developed to help students to prepare for entrance and competitive examinations, 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 being developed at 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 Human Resource Development (MHRD), through its National Mission on Education through Information and Communication Technology (NMEICT), has sponsored and funded the National Digital Library of India (NDLI) project.
