Importing Vitamin C Preparations: Key Points and Precautions for Choosing High-Quality Overseas Formulations | TASAKI PHAMA

Current Status and Challenges of Importing High-Quality Vitamin C Formulations

In recent years, the demand for vitamin C formulations in medical institutions has been increasing. In particular, high-dose vitamin C intravenous therapy is gaining attention as an adjunct therapy for cancer treatment and anti-aging therapy. However, the supply of domestic vitamin C formulations, especially high-quality preservative-free formulations, is unstable, and prices tend to soar. Given this situation, there is growing interest in importing high-quality vitamin C formulations from overseas.

In particular, ascorbic acid formulations manufactured by established pharmaceutical companies such as Mylan are in demand at many medical institutions due to their high quality. However, the import of overseas formulations presents various challenges, including quality control, pharmaceutical regulations, and transportation costs.

Current Status of Domestic Vitamin C Formulations

Domestic vitamin C formulations are well-established for their high quality, but the current situation is that demand cannot be met due to manufacturing costs and supply constraints. In particular, high-quality preservative-free formulations require advanced manufacturing technology, which tends to drive up prices and make stable supply difficult.

Expectations for Overseas Vitamin C Formulations

Overseas vitamin C formulations are generally relatively inexpensive and are expected to be stably supplied. In particular, formulations manufactured by European and American pharmaceutical companies have strict quality control standards and are considered to be high-quality products. For example, Mylan’s (now Viatris) Ascorbic Acid Injection is used in many countries and is highly regarded for its quality.

Selection Criteria for High-Quality Vitamin C Formulations

When selecting overseas vitamin C formulations, it is important to consider the following points:

• Manufacturer Reliability: Check the size, track record, and quality control system of the pharmaceutical company. Whether it has been approved by regulatory authorities such as the FDA (U.S. Food and Drug Administration) and EMA (European Medicines Agency) is also an important indicator.
• Ingredient Purity: Choose products with high ascorbic acid purity. The lower the impurity content, the lower the risk of side effects.
• Presence or Absence of Preservatives: When used in high-dose vitamin C intravenous therapy, it is desirable to choose preservative-free products. Preservatives can cause allergic reactions and vascular irritation.
• Formulation Stability: Choose formulations with high stability so that quality does not deteriorate during distribution and storage.
• Price: Check that the price is appropriate for the quality.

Examples of Specific Drug Names (Generic Name/English Name)

• Ascorbic Acid Injection: A common formulation used for high-dose vitamin C intravenous therapy.

Precautions When Importing Overseas Vitamin C Formulations

When importing overseas vitamin C formulations, the following points should be noted:

• Pharmaceutical Regulations: Check whether the formulation is permitted to be imported based on the Japanese Pharmaceutical Affairs Law (Act on Securing Quality, Efficacy and Safety of Pharmaceuticals, Medical Devices, etc.).
• Quality Control: Manage the temperature control and transportation methods during the distribution process to maintain quality.
• Customs Clearance: Prepare the necessary documents for import and carry out customs procedures appropriately.
• Storage Method: Comply with appropriate storage methods according to the characteristics of the formulation.
• Information Gathering: Collect the latest information on the formulation and check its safety and efficacy.

Use of Import Agency Services

Importing overseas vitamin C formulations requires specialized knowledge and procedures, so it is also effective to consider using an import agency service. Import agency services can handle pharmaceutical regulations, quality control, customs procedures, etc., which can reduce the burden on medical institutions.

Importance of Vitamin C Formulations in Medicine and Future Prospects

Vitamin C has various physiological activities such as antioxidant action, immune-enhancing action, and collagen production-promoting action, and its importance in medicine is increasing. High-dose vitamin C intravenous therapy is expected to improve QOL (quality of life) and prolong life as an adjunct therapy for cancer treatment. Vitamin C formulations are also widely used in aesthetic medicine and anti-aging medicine.

In recent years, research on the anti-cancer effects of vitamin C has also progressed, and selective toxicity to specific cancer cells and enhancement of therapeutic effects in combination with immune checkpoint inhibitors (e.g., Pembrolizumab, Nivolumab) have been reported. Future research is expected to open up new possibilities for vitamin C formulations.

For example, a study published in the Journal of Translational Medicine suggested that high-dose vitamin C therapy may improve the QOL of patients with advanced cancer.

Summary

A stable supply of high-quality vitamin C formulations is an important issue in the medical field. The import of overseas formulations is expected as one solution, but it is necessary to overcome issues such as quality, pharmaceutical regulations, and transportation. Medical institutions must collect information from reliable sources, select appropriate formulations, and strive for safe import and use. Future research is expected to open up new possibilities for vitamin C formulations.
