The coming wave of patent expiries of first generation commercialized biotherapeutical drugs has seen the global market open its doors to close copies of these products. These near perfect substitutes, which are termed as “biosimilars”, do not need to undergo intense clinical trials for their approval. However, they are mandated to produce identical similarity from their reference biologics in terms of clinical safety and efficacy. As such, these biosimilar products promise to foster unprecedented access to a wide range of life-saving biologics. However, seeing this promise be fulfilled requires the development of biosimilars to be augmented with product trust, predictable regulatory frameworks, and sustainable policies. It is vital for healthcare and marketing professionals to understand the critical challenges surrounding biosimilar use and implement informed clinical and commercial decisions. A proper framework of pharmacovigilance, education, and scientific exchange for biologics and biosimilars would ensure a dramatic rise in healthcare access and market sustainability. This paper seeks to collate and review all relevant published intelligence of the health and business potential of biosimilars. In doing so, it provides a visualization of the essential steps that are required to be taken for global biosimilar acceptance.

Our results indicate that BRCA1/BRCA2, RAD51rs1801320 and HER2rs1136201 polymorphisms were associated with breast cancer in the studied population.

The high demand for and resulting financial success of biopharmaceutical products over the last three decades have seen the door open for close copies of these biological products, also known as biosimilars. This paper seeks to collate all relevant published intelligence with acquired survey data to assess the weight of available evidence that these products hold immense potential for the pharmaceutical industry in terms of their applications and benefits. Biosimilars also pose to be of great promise to the Bangladesh pharmaceutical industry, with the commitment of drastically reducing its dependence on foreign imports of biopharmaceutics to meet local demand. Our questionnaire based survey involved 100 Clinicians, 50 Industry Experts and 100 Academicians. The study found that majority of Industry Experts (72%) and Academicians (63%) shared a different concept of biosimilars opposed to majority of Clinicians (78%). Majority of Academicians (68%) and Industry Experts (61%) also shared a different belief from that of most Clinicians (61%) regarding the need for updating the existing regulatory guidelines. The study also showed that Clinicians (67%), Industry Experts (83%) and Academicians (80%) highlighted the benefit of lower costs of biosimilars. Furthermore, the quality data obtained from the survey results allowed us to evaluate and provide recommendations for stakeholders on the need for increased biosimilar awareness, pharmacovigilance and safety in Bangladesh.

The aim of the paper was to formulate a combined oral dosage form of rosuvastatin calcium and amlodipine besylate and to develop and validate an analytical method to be adopted for both routine quality control assay and dissolution studies of the formulation. The proposed combination formulation has shown compatibility with the chosen excipients, verified through FT-IR study. A novel gradient RP-HPLC method was developed and validated according to the ICH guideline which was found to be suitable for the simultaneous estimation of rosuvastatin calcium and amlodipine besylate from the formulation. The retention time of 2.7 and 6.08 min allows the analysis of large amount of samples with less mobile phase which makes the method economic. The dissolution profiles of both the drugs in different dissolution medium were encouraging which makes the combination formulation of rosuvastatin calcium and amlodipine besylate superior and effective in achieving patient compliance.
