Misconception of regulatory classification of medical products


regulatory classifica

Registration of a medical product starts with an official classification  which will determine the documentary requirements, timelines, and fees. Today we are going to share a few misconceptions and the approach to classify a product correctly.

Misconception

  1. We assume that the classification in the country of origin will be the classification in the country to be exported . E.g A product that is a classified as an OTC product in the country of origin might be deemed as a medical device in the country where it is exported to.
  2. We did not check the definition of a specific category of the product based on local regulations. We assume the definition based on what we understand in common regarding a specific category of product. E.g a medical device should only treat, diagnose, and prevent a medical condition through “mechanical action” but not by immunochemical or pharmacological means.
  3. Marketing claims which might not be suited for the specific category of the product such as health supplement that might overclaim its function without referencing to established pharmacopeia or proven efficacy through human studies such as a clinical trial.

Approach to classification of a product

  1. Active ingredient- Is this a Poison or controlled substance under the Pharmaceutical Act? What is the strength or allowable limit of a substance that might put it at risk of being categorized as a higher risk product?
  2. Mode of action- Does the principle of action qualify it as more” therapeutic” in a pharmaceutical way or relieving or replacement of a physiological process like a medical device?
  3. Indications- Are the indications backed by clinical studies or literature papers? Does the indications allow you to classify as a lower category then what it actually is?
  4. Matching the definition in regulatory guidelines – Considering the above elements, do a check against the definition to see whether it meets the classification that you think your medical product would fit.
