CEP (Certificate of European Pharmacopoeia), ASMF (Active Substance Master File), and Letter of Access are all related to the registration and approval process for pharmaceutical products in the European Union (EU).

A CEP is a document issued by the European Directorate for the Quality of Medicines (EDQM) that certifies the compliance of the pharmaceutical substance with the European Pharmacopoeia. It provides information about the quality, safety, and purity of the substance.

An ASMF, also known as a Drug Master File (DMF), is a confidential document that contains detailed information about the manufacturing process, quality control, and stability data of the active substance. It is submitted by the manufacturer to the regulatory authorities as part of the drug approval process.

A Letter of Access is a document issued by the owner of a CEP or ASMF, granting access to the information contained in those files. It allows a pharmaceutical company to refer to the CEP or ASMF during their own product registration process without revealing the confidential information.

If you are inquiring about the availability of a CEP, ASMF, or Letter of Access for a specific product, you may need to contact the manufacturer or supplier directly to obtain this information.
