Nitrosamines are a growing concern in the pharmaceutical world because they are considered potential cancer-causing substances. To keep medicines safe, global agencies have set strict limits on how much nitrosamine can be safely present in a drug. These limits are called acceptable intake nitrosamines levels. Meeting these standards is crucial not only for patient health but also for regulatory approval and market success. At ResolveMass Laboratories Inc., we support pharmaceutical companies with accurate nitrosamine testing, risk assessments, and expert research support.
Introduction: What Does Acceptable Intake Nitrosamines Mean?
The term acceptable intake nitrosamines refers to the maximum daily amount of a specific nitrosamine that a person can be exposed to over a lifetime without a major health risk. Health agencies like the FDA, EMA, and WHO have published these limits to keep patients safe from cancer-causing chemicals in medicines.
In recent years, several medicines were found to contain nitrosamines, raising global concern. To respond to this, ResolveMass Laboratories Inc. provides advanced tools to detect and measure nitrosamines in both raw drug materials and finished products. We help our clients stay ahead of changing regulations with clear reporting and expert toxicology support.
What Are Nitrosamines?
Nitrosamines are chemicals that can form when certain ingredients in drugs mix under the right conditions, such as heat or moisture. Some well-known nitrosamines include NDMA, NDEA, and NMBA. These have been linked to cancer in animal studies and are being closely watched by health authorities.
Nitrosamines have been found in drugs like Sitagliptin, Amitriptyline, Cinacalcet, and Betahistine. Because of this, manufacturers must test their drugs thoroughly. ResolveMass Laboratories has developed and validated special testing methods for these medications to help ensure safety and compliance.
ResolveMass has developed validated testing protocols for all the above APIs and more:
- Nitrosamine Testing in Sitagliptin
- Nitrosamine Testing in Amitriptyline
- Nitrosamine Testing in Cinacalcet
- Nitrosamine Testing in Betahistine
Regulatory Guidelines for Acceptable Intake Nitrosamines
Both the FDA and EMA have shared official intake limits for different nitrosamines. These numbers show how much of each compound is considered safe per day:
| Nitrosamine | Acceptable Intake Limit (ng/day) |
|---|---|
| NDMA | 96 |
| NDEA | 26.5 |
| NMBA | 96 |
| DIPNA | 26.5 |
| EIPNA | 26.5 |
Understanding these limits helps pharmaceutical companies avoid delays, product recalls, or even bans. ResolveMass helps businesses interpret these rules and apply them correctly to each drug product.

What Affects Acceptable Intake Nitrosamines Levels?
1. Toxicity Data
Regulatory limits are based on long-term animal testing. The lowest doses that caused harm are used to calculate safe levels for humans using special models.
2. How Long Someone Is Exposed
Usually, these limits are for lifetime exposure. But in some cases, if exposure is short-term and backed by scientific data, a small increase may be allowed.
3. How the Drug Is Taken
The method of taking the drug (by mouth, injection, or inhalation) affects how much nitrosamine gets into the body. This is taken into account when setting limits.
4. Complex Nitrosamines
Some nitrosamines are linked to the drug’s structure and are harder to study. These are called NDSRIs (Nitrosamine Drug Substance-Related Impurities). Our experts at ResolveMass help identify and assess these challenging compounds. We offer extensive guidance on NDSRIs:

Testing Strategy for Acceptable Intake Nitrosamines
Step 1: Risk Review
We begin by looking at the drug’s ingredients, manufacturing steps, and packaging to see where nitrosamines might form.
Step 2: Advanced Testing
We use cutting-edge tools like LC-MS/MS and GC-MS to detect nitrosamines in very small amounts—down to parts per billion—matching global safety requirements.
Step 3: Toxicology Reports
Our experts prepare scientific reports to justify safety levels. These help companies explain their findings to regulatory bodies.
Why Acceptable Intake Nitrosamines Should Not Be Ignored
Failing to meet acceptable intake nitrosamines levels can lead to serious issues, including:
- Warning letters from regulators
- Drug recalls
- Delays in product approval
Most importantly, it can put patient safety at risk. At ResolveMass, we work closely with our clients to catch problems early and offer smart solutions.
Future Outlook on Acceptable Intake Nitrosamines
- AI-Powered Tools: Smart software is now used to predict nitrosamine risks even before testing begins.
- Custom AI Limits: Future drugs may have intake limits tailored to individual patient metabolism.
- Regulations Will Keep Changing: Pharmaceutical companies must stay flexible and ready to adapt as new rules are introduced.
ResolveMass is actively updating our methods and tools to keep up with these industry trends.
Conclusion
Keeping nitrosamine levels below the acceptable intake nitrosamines threshold is essential for public health and product success. ResolveMass Laboratories offers expert testing, toxicology support, and regulatory advice to help companies stay compliant. With our help, pharmaceutical businesses can move forward with confidence, knowing their products are both safe and regulation-ready.

FAQs
The acceptable intake of nitrosamine is the highest amount a person can take every day over a lifetime without health risks. It is usually measured in nanograms (ng) per day. This limit helps protect people from the cancer risk linked to long-term nitrosamine exposure.
The FDA has set specific daily intake limits for different types of nitrosamines. For example, NDMA’s limit is 96 ng/day and NDEA’s is 26.5 ng/day. These limits are based on safety studies and aim to reduce cancer risk from contaminated medicines.
The total nitrosamine limit is the combined amount of all detected nitrosamines in a drug product. This ensures that even if multiple nitrosamines are present, their total intake stays within a safe range. It helps ensure overall patient safety.
The ICH (International Council for Harmonisation) guideline M7(R2) provides safety limits and control strategies for nitrosamine impurities. It focuses on identifying risks, setting acceptable intake levels, and using proper testing to make medicines safe from harmful levels of nitrosamines.
The nitrosamine limit is calculated using animal cancer study data and risk models. Experts estimate the amount that would cause no more than one extra cancer case in 100,000 people over a lifetime. This becomes the basis for the daily intake limit in humans.
To control nitrosamine impurities, manufacturers need to assess risks in their processes, use clean raw materials, avoid nitrosating agents, and test products with sensitive methods like LC-MS/MS. Regular monitoring and proper storage also help reduce nitrosamine formation.
Yes, nitrosamines can form during the production or storage of APIs like Sitagliptin. In some cases, low levels of nitrosamines have been found in Sitagliptin-based drugs, which may pose a health risk if not properly controlled. That’s why specific nitrosamine testing is important for such APIs.
Sitagliptin Nitrosamine Testing
To ensure your drug meets acceptable intake (AI) compliance, you should start with a thorough risk assessment of your manufacturing process. Then, test your product using advanced methods like LC-MS/MS. Working with expert labs like ResolveMass helps ensure you meet global nitrosamine safety limits.
