| Abstract | 4-Aminosalicylic acid (4ASA) a non steroid anti inflammatory drug (NSAID) has been used for over 40 years in the treatment of inflammatory bowel diseases (IBDs). It is therefore an importance to assess physicochemical properties such as solubility and stability. The effect of cyclodextrins on the solubility and chemical stability of 4ASA was investigated. Inclusion complexes of 4ASA were characterized by the solubility method, differential scanning calorimetry (DSC) and Fourier transformer infrared spectroscopy (FT-IR). In addition, the influence of presence of CDs on stability was assessed at room temperature in different pH conditions. Complexation with CDs increased 4ASA aqueous solubility. The stoichiometric ratios of the inclusion complexes were 1:1 for α, β, γ and HP- CDs, respectively. Complexation with γ and HP-CDs has increased the 4ASA stability 4 fold. These observations suggest that 4ASA/CD complexes may be an attractive and practical procedure to modify drug physicochemical properties for use in delivery systems. |

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.
