Nitrosamine unintended chemicals are unwanted by-products that can form during the manufacturing, storage, or degradation of certain drugs.

Organic nitroso compounds are chemical substances containing the nitroso-functional group (–N=O) bonded to a carbon atom.

Nitrosamine drug contaminants, also called nitrosamine drug impurities, are chemicals known as nitrosamine carcinogenic-risk impurities because they may cause cancer.

The risk evaluation of nitrosated agents centers on nitrosamines, which belong to a high-risk nitrosamine chemical hazard class and are widely recognized as genotoxic impurities due to their DNA-damaging and carcinogenic potential.

Nitrosamine degradation products are formed when unstable N-nitroso compoundsbreak down in pharmaceutical formulations or environmental matrices

Nitrosamine-class chemicals are organic substances containing a nitroso (–N–N=O) group bonded to an amine.

Nitrosamine compounds are a critical quality concern because many are potentially carcinogenic and can be harmful even at very low levels, making their control essential in pharmaceuticals

Embryo-fetal toxicity refers to harmful effects on a developing embryo or fetus due to exposure to certain substances, such as medications, chemicals, or environmental factors.

Fluid retention, also known as water retention, occurs when excess fluid builds up in the body's tissues, causing swelling often in the hands, feet, ankles, or legs.
