In bioequivalence studies (BE studies), reference drugs play a pivotal role in ensuring the accuracy and validity of trials. But what exactly is a reference drug?
What is a Reference Drug?
According to Circular 07/2022/TT-BYT a reference drug is a drug that a generic drug aims to replace in treatment. Typically, reference drugs are either innovator products or drugs that have been granted marketing authorization with complete data on efficacy, safety, and quality.
What drugs are commonly used as Reference Drugs?
1. List of Original Brand-Name Drugs: Drugs selected from the list of original brand-name drugs announced by the Ministry of Health, or drugs that have been granted marketing authorization with complete data on quality, safety, and clinical efficacy.
2. Drugs Approved by Stringent Regulatory Authorities (SRAs):
- Innovator drugs that have not been granted marketing authorization in Vietnam but have been approved by one of the SRAs and are being marketed in those countries;
- Drugs that have been approved by one of the SRAs and are being marketed in those countries.
3. Drugs which are prequalified by the World Health Organization (WHO).
Challenges in Sourcing Reference Drugs from Overseas:
- Finding Suppliers: Many businesses struggle to find reliable suppliers, making it difficult to access products. The requirement for complete documentation, including invoices, is also a significant challenge when selecting a supplier.
- Complex Import and Export Procedures: The import and export of drugs can be time-consuming and laborious, extending the duration of research and testing.
