Combination products, those integrating a medicinal substance with a medical device, are increasingly relevant in modern healthcare. These products enable targeted delivery, improve patient adherence, and optimize therapeutic outcomes. This article provides an overview of combination products, their classification, and regulatory considerations under Mexican standards.
What Are Combination Products?
Combination products are defined as healthcare products that incorporate both a pharmaceutical component (active ingredient or drug) and a medical device (delivery system or application mechanism).
Common examples include:
- Pre-filled syringes and pens for injectable medications
- Drug-eluting stents used in cardiovascular interventions
- Inhalers combining bronchodilators or corticosteroids with a device for pulmonary administration
These products are designed to deliver medication through a controlled mechanism, ensuring accurate dosing and improved safety.
Regulatory Classification in Mexico
Under Mexican regulation, classification depends on the primary mode of action. However, when a medical device incorporates a drug as an integral part, the regulatory framework is clear:
Medical devices that incorporate a drug or medication are those that include, as an integral part, a drug or medication that exerts on the human body a secondary or additional action to that of the medical device.
According to the Medical Device Supplement from the Mexican Pharmacopoeia, these products are classified as Class III medical devices, given their complexity and risk profile:
All medical devices that incorporate, as an integral part, a substance that when used separately is considered a medicine […] will belong to Class III.
This classification entails rigorous safety, efficacy, and quality requirements, including the evaluation of both the device and the medicinal component. It is also important to note that registering combination products in Mexico is inherently more complex, as regulatory submission must include complete technical and legal documentation from both the drug manufacturer and the medical device manufacturer.
In addition, these products must account for characteristics that can directly affect the medicinal substance (such as packaging interactions with light, humidity, and other environmental factors) making their assessment and approval more demanding.
Registration Pathways and Grouping Criteria
For manufacturers seeking registration in Mexico, the following considerations apply:
- Single Registration: Combination products are generally registered under one sanitary registration, provided they are marketed as a unified system.
- Grouping: Multiple presentations (e.g., different dosages or device sizes) may be grouped if they share:
-
- Same manufacturer
-
- Same commercial name
-
- Same intended use
-
- Same technology platform
Additional documentation is required to demonstrate compatibility and safety of both components.
Frequently Asked Questions (FAQ)
- What are combination products in healthcare?
Combination products are medical technologies that integrate a medicinal product and a medical device into a single system. Examples include drug-eluting stents, pre-filled syringes, and inhalers with medication delivery mechanisms. These products are designed to improve therapeutic outcomes by combining controlled drug administration with device functionality.
- How are combination products classified under Mexican regulations?
According to COFEPRIS and the FEUM Supplement, combination products where a device incorporates a drug as an integral part are classified as Class III medical devices.
- Why is the regulatory submission for combination products more complex in Mexico?
Regulatory submission for combination products in Mexico is more complex because authorities must evaluate both components of the product—the medical device and the medicinal substance. This requires complete technical and legal documentation from both the device manufacturer and the drug manufacturer, ensuring that each part meets its respective regulatory standards. As a result, the approval pathway is more rigorous than for standalone devices or medications.
Conclusion
Combination products are among the most complex categories regulated in Mexico because they integrate a medical device and a medicinal substance, requiring full technical and legal documentation from both manufacturers. This dual‑compliance obligation makes their registration far more demanding than standard submissions.
