Nanotechnology ^

Nanotechnology is an emerging technology that can be used in a broad array of regulated products. The nanoscale range differs by region. Nanoscale materials can exhibit different chemical or physical properties, or biological effects compared to larger-scale counterparts. [EIP]

Nitrosamines and related compounds ^

A functional group classified as a probable human carcinogen. It is therefore a contamination concern for pharmaceuticals, for which a risk assessment is often performed on the API or excipient. [EIP]

NOAEL

No-Observed-Adverse-Effect Level

NOEL

No-Observed-Effect Level

Nominal Component

The main component for which the excipient is named. For an excipient mixture, the main component may not be present at greater than 50%.

Normal Variability ^

The variability expected to be obtained for the excipient during typical processing and evaluation when the process operates in a state of control with no special causes of variation. [Significant Change]

Novel Excipient

An excipient used for the first time in a drug product or a new route of administration or a higher level of use in a drug product. When a novel excipient chemistry is used for the first time in a drug product it is referred to as a new chemical entity (NCE).
