| Abstract | The effects of different formulation variables on the transdermal absorption of donepezil were investigated. The permeation of donepezil from various pressure sensitive adhesive matrices was evaluated using flow-through diffusion cell system at 37°C. The penetration of donepezil from the matrices was found to be influenced by the nature of adhesives. 1:1 combination of acrylic rubber hybrid adhesives (Duro-Tak$^{®}$ 87-503A and Duro-Tak$^{®}$ 87-504A) provided good adhesion force and high flux of donepezil. Significant increase in flux was obtained using Brij$^{®}$ 30, Brij$^{®}$ 52, and their combination, as penetration enhancers. Manual assessment using thumb test revealed that patches containing combination of enhancers possessed good adhesive properties. The formulation containing combination of Brij$^{®}$ 30 and Brij$^{®}$ 52, each at the level of 5% v/w with 15% w/w drug load in 1:1 combination of Duro-Tak$^{®}$ 87-503A and Duro-Tak$^{®}$ 87-504A matrix was found to be the best. No significant alteration in morphology and assay values were observed during the physical and chemical stability tests conducted for the study period of 3 months. |

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.
