Nitrosamine Risk Assessment Calculator

An interactive, science-based tool designed to help you assess nitrosamine formation risk and optimize acceptable nitrite limits in your formulation.

To support different stages of formulation development and risk evaluation, the Nitrosamine Risk Assessment Calculator is structured into two complementary modules: a Basic Calculator for rapid initial assessment and an Extended Calculator for in-depth analysis and optimization.

Free to use – no limitations. Simply log in or register and get started.

Basic Calculator

– Provides a first estimate of the overall nitrite limit
– Assumes additive nitrite contribution from excipients within the tablet
– Compares potential daily intake against applicable regulatory thresholds
– Serves as a structured first-step screening

For advanced quantitative evaluation, use the Extended Calculator

Extended Calculator

– Advanced Quantitative Risk Evaluation
– Calculates potential nitrosamine daily intake for your selected formulation
– Defines acceptable daily intake (ADI) and evaluates conversion assumptions
– Determines estimated nitrite limits for excipients, including 10% thresholds
– Provides a transparent summary of API, excipient contribution, and conversion
– Delivers targeted recommendations to reduce nitrosamine formation risk
(e.g., low-nitrite excipients, process optimization, scavengers, packaging
improvements)

Nitrosamine Risk Assessment Calculator

Our Nitrosamine Risk Assessment Calculator supports you with a structured, science-based evaluation of potential nitrosamine formation in your drug product. Based on EMA Appendix 1 (updated March 2026), the tool enables you to estimate acceptable nitrite limits, calculate potential daily intake, and identify formulation optimization strategies – all within minutes.

Important notice: The Nitrosamine Risk Assessment Calculator provides an indicative estimate only. The results are based on the data entered by the user and do not replace a product-specific risk assessment, regulatory evaluation, or validated analytical testing. Actual nitrosamine levels can only be determined by appropriate analytical testing.
