| Abstract | Ifosfamide is a widely used antineoplastic drug belonging to the alkylating agents. It is difficult to develop a conventional oral dosage form as it degrades in acidic media, with its rate of degradation depending on the pH of the solution. Thereby, ifosfamide is available either as a powder which is reconstituted with diluents for injection or as injectable solution. The present work has attempted to improve oral bioavailability of ifosfamide by incorporating in nanostructured lipid carriers (NLCs). The purpose of this research was to study whether the oral bioavailability of ifosfamide could be improved by administering ifosfamide-loaded NLCs.Ifosfamide NLCs were developed using chitosan cross-linking with sodium alginate by solvent diffusion technique. Bioavailability studies were conducted in albino rats after oral administration of ifosfamide suspension and NLC. In vivo antitumor activity of ifosfamide nanostructured lipid carrier against Dalton’s ascitic lymphoma (DAL) was also investigated.The results showed that the relative bioavailability of ifosfamide from NLC was increased by sixfold higher than that of ifosfamide suspension. Administration of ifosfamide NLC significantly decreased the tumor volume and viable cell count. Nonviable cell count was significantly higher in ifosfamide NLC-treated animals when compared with DAL control animals. Further, the median survival time was increased to 35 % on administration of ifosfamide NLC. Ifosfamide NLC significantly decreased biochemical parameters, increased the RBC count and Hb content, and reduced the WBC count as well.The results of this study show no significant difference in the antitumor efficacy of ifosfamide when administered as injection and nanoformulation. The obtained results are indicative of NLCs as potential carriers for improving the oral bioavailability and acid instability problems. The new nanoformulation would be interchangeable with the standard formulation. |

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.
