Abstract
Development of generic drug product by pharmaceutical industry is a scientific and technical approach which is totally different from developing a reference or innovator product. Most of the developing countries focus on developing the generic drug products because huge amount of investment is required for innovation and to develop reference product. The generic medicine has to be bioequivalent to the innovator drug and ensure the same biological effect with proper safety and efficacy. Nowadays, the pharmaceutical industries focus on the development of generic product as this does not require that much time and cost compared to the innovator company. But development of generic product is also difficult as it contains the same therapeutic efficacy as innovator. The development approach is based on the target market, i.e. US market, EU market. If a manufacturer targets the US market, then all excipients should be USP grade, analysis should be conducted by USP method or in-house method and stability studies as well. Prior and during the development of generic drug product API selection, dosage form selection, reference product selection and characterization, formulation development, analytical method development, tech transfer or submission batch are prime concern. Then again, bioequivalence study, drug registration procedure and commercialization of the generic product considering regulatory guidance of respective regulatory agencies and the approaches taken by the regulatory agencies for the development of registration of generic medicines are also crucial as well for the development of generic drug product. The aim of this study was to review the entire stage of a generic drug development by a generic pharmaceutical company.

Summary
Developing a generic drug product in pharmaceutical industry is a scientific and technical approach which is totally different from developing an innovator product that takes several years and stages to be registered as an innovator product [1]. Generic drug products are cost-effective than their respective brand products [3]. Pharmaceutical industries try to formulate and develop a generic product which is therapeutically equivalent to the innovator product. Though development of generic product does not require that much time and cost compared to the innovator company, but it is very difficult to develop a product containing the same therapeutic efficacy compared to innovator and to meet all the regulatory requirements as well [1]
