Witrynacontribute to the impurity profile of the new drug substance, and possible degradation products. This discussion can be limited to those impurities that might reasonably be expected based on knowledge of the chemical reactions and conditions involved. In addition, the applicant should summarise the laboratory studies conducted to ... WitrynaThe impurity profile depends very much on the manufacturing process; even for the same strain of a micro-organism, impurity profiles may be different. In general, purification steps including column chromatography and ultra-filtration steps may be crucial to achieve a sufficiently pure active substance.
