| Abstract | OBJECTIVE: The aim of the study was to investigate the bioavailability of a generic formulation of 10-mg bisoprolol film coated tablets (test) as compared to that of a branded formulation (reference) at the same strength to determine bioequivalence and to apply for regulatory approval. The secondary objective of the study was to evaluate tolerability of both formulations. METHODS: A randomized, crossover, open-label, 2-period, single-dose, comparative study was conducted in healthy white volunteers in fasting conditions. A single oral dose administration of the test or reference formulation was followed by a 14-day wash-out period. Blood samples were collected up to 60 hours after dosing. The bisoprolol concentrations in plasma samples were determined using a validated LC-MS/MS method. The formulations were considered bioequivalent if 90% CI of geometric mean ratios (test/reference) for AUC0-t, AUC0-∞ and Cmax were within the range 80.00 - 25.00%. Adverse events were monitored throughout the study based on the clinical parameters and volunteer reports. RESULTS: Healthy male and female subjects participating in the study had a median (range) age of 23 (20 - 43), weight of 68 kg (52 - 84), height of 172 cm (157 - 184), and BMI of 23.1 kg/m2 (19.3 - 24.9). The 26 consented volunteers have been included and 24 of them completed the clinical part of the study. The geometric mean test/referenceratios (90% CI) for AUC0-t, AUC0-∞ and Cmax were 104.12% (100.52 - 107.85%), 104.05% (100.49 - 107.75%) and 107.91% (103.04 - 112.99%), respectively. All 90% CI were embraced by the 80.00 - 25.00% acceptance interval. No serious adverse events were reported. A total number of 6 non-serious, moderate adverse events were registered, including headache and vomiting in one subject. CONCLUSIONS: The results of the single-dose study in healthy white volunteers indicated that the film-coated tablets of Bisocard® 10 mg manufactured by ICN Polfa Rzeszów S.A. (test formulation) are bioequivalent to those of Concor 10® manufactured by Merck KGaA (reference formulation). Both formulations were well tolerated. |

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.
