Drug Classification Map: How Western Medicine / Traditional Medicine / Supplements Are Distinguished (Malaysia)

In Malaysia, whether a product is a "Western medicine, a traditional medicine, or a health supplement" is not for the manufacturer to decide, but is determined comprehensively by the National Pharmaceutical Regulatory Agency (NPRA) based on ingredient, dosage form and claim. This classification directly decides three things: the registration category, the ending letter of the MAL number, and where it can be sold and how it can be advertised. All four product categories must be registered and all carry a MAL number, but the depth of review and the strength of control differ greatly. Understand this map so you do not submit a product that should go through T as a supplement, or sell something containing a poison ingredient as an OTC medicine.

The four categories and MAL number endings

For medicinal products registered with the NPRA, the ending letter of the MAL number (format MAL + 8 digits + one letter) is the classification code:

(Cosmetics go through a separate NOT notification scheme, not a MAL, and are outside the four categories in this article.)

The three rulers that decide classification

When the NPRA judges whether a "food–drug interface (FDI)" product should be a medicine or a food, and which category it belongs to, it mainly looks at:

1. Ingredient - Containing a poison scheduled in the First Schedule of the Poisons Act 1952, or a high-pharmacological-strength ingredient (such as paracetamol, aspirin), classifies it as a medicine, mostly falling under A. - Containing an ingredient on the NPRA "negative list" (such as glucosamine, resveratrol, placenta extract, and dozens of others) classifies it as a medicine even if it looks like a food.

2. Dosage form - Made into a "medicine-like form" such as capsules, tablets, softgels, sublingual / oral sprays, it tends to be judged a medicine rather than a food.

3. Claim - Once it claims to prevent, treat or diagnose disease, it is for a medicinal purpose and cannot be sold as an ordinary food. - Herbal ingredient + traditional-efficacy appeal → mostly classified as T (traditional medicine); pure nutritional supplementation with no disease claim → mostly classified as N (health supplement).

Where there is a safety concern, the NPRA tends to be strict and regulate it as a medicine. For example: the same turmeric, made into a culinary powder, is a food; made into a capsule marketed for "liver protection, anti-inflammation," it is pushed toward the medicine category by its dosage form and claim, and must be registered under T or N. The difference is not the raw material but how you present and claim it.

The Poisons Act 1952: why Western medicine is regulated most strictly

Controlled medicines (A) are the strictest precisely because they contain poisons listed in the First Schedule of the Poisons Act 1952 (Act 366). That schedule further divides poisons into Groups A–F by strength and manner of dispensing, which determines the sale and dispensing conditions, for example:

• Group A poisons: supplied only by licensed wholesalers to licensed pharmacists / wholesalers.
• Group B poisons: require a prescription from a registered doctor / dentist / veterinarian and are retailed by a registered pharmacist.
• Group C poisons: community pharmacists may supply without a prescription under certain conditions.

By contrast, OTC medicines (X) contain no scheduled poisons and can be retailed over the counter; traditional medicines (T) and health supplements (N) each have their own positive / negative ingredient lists and labelling rules.

What happens if the classification is wrong

• Under-declaring as lower risk: selling a herbal medicine that should be registered as a traditional medicine (T) as an ordinary food or supplement means it is not registered under the correct category → it is an unregistered product, facing seizure and removal.
• Contains a poison but treated as OTC: a product containing a First Schedule poison but not going through the controlled-medicine (A) / prescription channel violates the Poisons Act 1952.
• Claim crosses the line: once a health supplement (N) makes a disease-efficacy claim, it is treated as medicinal, and the classification and advertising all have to start over.

Frequently asked questions (FAQ)

Q: How can the same capsule end up in different categories? The key is the ingredient and the claim. Pure nutrition, no efficacy → health supplement (N); herbal + traditional efficacy → traditional medicine (T); containing a scheduled poison or high-strength Western-drug ingredient → controlled medicine (A). Change the dosage form and claim and the classification changes.

Q: How do I read the product category from the MAL number? Look at the ending letter: A = controlled medicine, X = OTC medicine, T = traditional medicine, N = health supplement. The number can be searched on the NPRA website to verify authenticity and validity.

Q: What is the difference between a health supplement and a traditional medicine? Health supplements (N) are mainly for nutritional supplementation and may not claim to treat disease; traditional medicines (T) are herbal / traditional-therapy products that may carry an approved traditional-use claim — their ingredient lists and reviews differ.

Q: Do cosmetics also have a MAL number? No. Cosmetics go through the NPRA's NOT notification scheme (a NOT number), a different system from the four MAL categories.

Q: What should I do if I am unsure which category my product belongs to? Cross-check against the ingredient / negative list and dosage-form rules in the NPRA Product Classification Guideline; where the boundary is blurry (e.g. the food / drug interface), it is advisable to confirm through NPRA classification consultation rather than deciding on your own.

Self-check checklist

• [ ] Confirmed the product's ingredients contain no First Schedule poison of the Poisons Act 1952 (otherwise it goes through A)
• [ ] Cross-checked the NPRA negative list to confirm it is not mandatorily classified as a medicine
• [ ] Whether the dosage form (capsule / tablet / spray) and the claim will push the product toward the medicine category
• [ ] Applied for MAL registration under the correct category (A / X / T / N)
• [ ] The claim is consistent with the classification, and health supplements make no disease-efficacy claim

Summary

Malaysia's drug classification is a map of "ingredient × dosage form × claim": containing a scheduled poison goes through controlled medicine (A), general OTC goes through X, herbal traditional therapy goes through T, pure nutritional supplementation goes through N, and the MAL number ending is the ID card. Classify correctly first, and only then can you talk about correct registration, labelling and advertising.
