| Abstract | The present study was performed to compare the bioavailability of 2 risedronate sodium 35 mg film-coated tablet formulations (test formulation and reference formulation). Prior to the present study, in vitro comparative dissolution test has been conducted for test and reference formulations. Dissolution profiles shown that more than 85% of the drug is dissolved within 15 min at pH 1.2, pH 4.5, and pH 6.8.This study was a randomized, single-blind, 2-period, 2-sequence cross-over study which included 48 evaluable healthy adult male and female subjects under fasting condition. In each of the 2 study periods (separated by a washout of 3 weeks) a single dose of test or reference drug was administered. The pharmacokinetic parameters assessed in this study were cumulative urinary excretion from drug administration to 72 h (Ae72h) and maximum urine excretion rate (dAe/dtmax). These parameters were determined from urine concentrations of risedronate and urine volume. Urinary concentrations of the drug were determined by high performance liquid chromatographic method with UV detector.The geometric mean ratios (90% CI) of the test drug/reference drug for risedronate were 106.60% (92.34-123.07%) for Ae72h and 104.75% (88.86-123.47%) for dA/dtmax. The geometric mean ratios calculated for Ae72h and dA/dtmax of risedronate were within the bioequivalence range (80.00-125.00% for Ae72h and dA/dtmax). It was concluded that the 2 risedronate sodium film-coated tablets (test and reference drugs) were bioequivalent. |

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.
