INTRODUCTION
Regulatory affairs play a crucial role in the pharmaceutical industry as they ensure the safety and efficacy of medicines for human use.The regulatory authorities of different countries have different requirements for the development, registration, and post-approval of pharmaceutical products.To ensure a consistent and harmonized approach to the regulatory affairs of pharmaceuticals, global organizations such as the International Council for Harmonisation of Technical Requirements for Pharmaceuticals for Human Use (ICH) have been established.The ICH brings together regulatory authorities and the pharmaceutical industry from around the world to develop and implement guidelines and standards that support the development of safe and effective medicines. 1e regulatory requirements of the countries under the MIST (Mexico, Indonesia, South Korea, and Turkey) and BRICS (Brazil, Russia, India, China, and South Africa) are different from those of ICH countries (Australia, Brazil, Canada, China, European Union, India, Japan, Russia, South Africa, South Korea, Singapore, Switzerland, Taiwan, United Kingdom, United States).These countries have their own unique regulations and guidelines, which may vary in terms of stringency, documentation requirements, and the length of the approval process.As a result, it is important for pharmaceutical companies to understand the specific requirements of each country to ensure a smooth and efficient regulatory process. 2 In this study regulatory dossier requirements of MIST and BRICS countries with those of ICH countries are reviewed and compared.The comparison will provide an insight into the similarities and differences between the requirements of the different regions and help pharmaceutical companies to better understand the regulatory landscape in each country.
MIST countries have made significant progress in recent years in terms of regulatory reform and harmonization, but there is still a long way to go before they can be considered fully harmonized with ICH guidelines.In many MIST countries, there is still a lack of clarity and consistency in the regulatory requirements, which can result in longer approval times and higher costs for pharmaceutical companies. 3n the other hand, the BRICS countries have some of the largest pharmaceutical markets in the world and are of strategic importance to the pharmaceutical industry.In recent years, the BRICS countries have made significant efforts to improve their regulatory systems and harmonize their requirements with those of ICH.However, there are still significant differences between the regulations in each country, which can make it challenging for pharmaceutical companies to navigate the regulatory landscape.Understanding the specific requirements and challenges of each country can help companies to develop a successful regulatory strategy, reduce the risk of regulatory delays and costs, and ultimately bring safe and effective medicines to patients more quickly. 4

ICH
The ICH guidelines and standards are developed through a collaborative process involving regulatory authorities and the pharmaceutical industry and are designed to be adaptable to changing circumstances and to reflect the specific needs and regulatory practices of each country. 5

BRICS
The BRICS countries are major players in the global economy and are home to some of the fastest-growing pharmaceutical industries in the world.The dossier requirements for BRICS countries are designed to ensure the safety and efficacy of new drugs for human use, and to provide a framework for the development and registration of pharmaceuticals in these countries.The dossier requirements for BRICS countries are designed to reflect the specific needs and regulatory practices of each country.For example, the requirements in Brazil, Russia, and South Africa may be influenced by local laws and regulations, as well as cultural and medical practices.In India and China, the requirements may be influenced by the large and rapidly growing populations, as well as the need to ensure access to essential medicines.The dossier requirements for BRICS countries are developed through a collaborative process involving regulatory authorities and the pharmaceutical industry.This collaboration helps to ensure that the requirements are relevant, practical, and responsive to the needs of both regulators and industry.The dossier requirements for BRICS countries are designed to be adaptable to changing circumstances.The guidelines and standards are regularly reviewed and updated to ensure that they remain relevant and up to date with the latest advances in scientific and medical knowledge.The introduction of dossier requirements for BRICS countries is also intended to help these countries become more competitive in the global pharmaceutical industry.The harmonization of requirements and the development of a robust regulatory framework can help to attract investment and innovation to these countries and support the growth of their pharmaceutical industries. 6

MIST
The MIST countries are rapidly developing economies with growing pharmaceutical industries.The primary purpose of the dossier requirements for MIST countries is to ensure the safety and efficacy of new drugs for human use.The requirements provide a framework for the development and registration of pharmaceuticals and help to ensure that the drugs meet the same high standards for safety and efficacy in different countries.Also, it is designed to reflect the specific needs and regulatory practices of these countries.The requirements may be influenced by local laws and regulations, as well as cultural and medical practices.These are developed through a collaborative process involving regulatory authorities and the pharmaceutical industry.This collaboration helps to ensure that the requirements are relevant, practical, and responsive to the needs of both regulators and industry.The guidelines and standards are regularly reviewed and updated to ensure that they remain relevant and up to date with the latest advances in scientific and medical knowledge. 3is also intended to help these countries become more competitive in the global pharmaceutical industry.The harmonization of requirements and the development of a robust regulatory framework can help to attract investment and innovation to these countries and support the growth of their pharmaceutical industries.As the MIST countries are important players in the global pharmaceutical industry, and the introduction of dossier requirements is a critical step in ensuring the continued growth and development of their pharmaceutical sectors.The requirements help to ensure that new drugs are safe and effective, and that the regulatory approval process is predictable and transparent. 7gional harmonization of the MIST countries is in different regions of the world, and the introduction of dossier requirements is intended to help promote regional harmonization in the regulatory approval process for pharmaceuticals.The harmonization of requirements can help to reduce the regulatory burden for the pharmaceutical industry and promote cross-border trade and investment in the pharmaceutical sector. 8e regulatory authorities in the MIST countries may provide technical assistance and support to the pharmaceutical industry in developing and submitting dossiers.This can help to ensure that the requirements are practical and easy to implement, and that the industry is able to take full advantage of the opportunities provided by the new requirements and are responsible for monitoring and enforcing compliance with the dossier requirements.This helps to ensure that the safety and efficacy of new drugs are protected, and that the regulatory approval process is transparent and predictable. 7
