Quality control and quality assurance for the intermediate zone between food and drug: Rational use of such products and the need to modify the pharmacy education

Abstract

General views on three aspects were discussed. The first aspect is regulatory categories, which can range from "soft to hard", an expression using the English and Japanese translation of the French term, "drogue douce" (soft drug). This categorization starts with "so-called health foods" and extends to Foods with Health Claims [Foods with Nutrient Functional Claims (FNFC); Foods with Functional Claims (FFC); Foods for Specified Health Uses (FOSHU)], OTC drugs, and ethical drugs. "The Basic Policy for New Drug Approval" (1967) made a distinction between OTC and prescription drugs. FOSHU (1991) originally included foods for "patients", such as low allergen rice with preventive "health claims". Foods for Medical Uses (FMU) later became an independent subcategory under Foods for Special Dietary Uses. On the other hand, manufacturers of FFC can make various "health claims" on the basis of randomized controlled trial or systematic review (2015). Products in the intermediate zone between food and drug have an annual market of over 2 trillion yen (US$ 20 billion). The second aspect is the five elements, i.e., quality, safety, e cacy, information, and cost, which are derived fromWHO's "The rational use of drugs" (1985). The adoption of Sustainable Development Goals (SDGs) by the UN General Assembly (2015) led to the addition of "ecology" as the sixth element, which is applicable for herbal and animal raw materials. The third aspect is quality control and quality assurance. This initially began with manufactured products and was expanded to the service fields handled by various health workers including pharmacists.
