                                                        The United States Pharmacopoeia (USP) is an independent, non-profit, non-governmental organization that provides technical regulations for pharmaceutical quality standards and testing methods. For drugs and related products manufactured and sold in the United States, USP-NF is the only statutory standard enforced by the US Food and Drug Administration (FDA). The standards issued by the USP have been recognized by more than 130 countries and regions around the world. The United States Pharmacopoeia standards were developed and revised by an international organization, and more than 800 professional volunteers work with USP in accordance with strict principles for avoiding conflicts of interest. Since its inception in 1820, USP has been helping to ensure the quality of US medicines. Following this tradition, usp today works with scientists, healthcare practitioners and regulators in many countries to protect public health around the world.


                                                        European Pharmacopeia, abbreviated as EP, "European Pharmacopoeia" is the only guidance document for European drug quality testing, EU drug quality and reliability assurance. Manufacturers of all pharmaceutical and pharmaceutical substrates must follow the European Pharmacopoeia quality standards in their marketing and use within Europe. The European Pharmaceutical Quality Administration (EDQM) is responsible for the drafting of the European Pharmacopoeia quality standards and the preparation of reference materials. There are currently 37 members including the European Union; including 23 observers, including the World Health Organization. All APIs used in APIs, botanicals, and pharmaceutical preparations sold in Europe, including excipients, must pass the EDQM certification CEP. EP currently offers more than 1,900 reference standards, and the European Pharmacopoeia monographs are officially valid, including chemical substances, biological products, and control maps.
