For example, we plan to adjust inspections of API sites to include enhanced evaluation of
impurity controls, particularly when the manufacturing process may lead to the formation of a nitrosamine or when recycled raw materials can create unacceptable contamination.
The recalled blood pressure medication has trace amounts of an unexpected
impurity, N-Nitroso-N-methyl-4-aminobutyric acid (NMBA), above the limits allowed by the U.S.
At that time, the Prime Minister had hit out at the Opposition parties which are making efforts to forge an anti-BJP coalition for Lok Sabha elections, terming it as aACoemaha milawat (grand
