To perform elemental impurity analysis, below are some necessary steps that should be considered. For other non-mandatory/not actively added elements, pharmaceutical companies can decide whether to include them in method verification based on their potential risks. Therefore, at this stage, it would be very simple to conduct the final method verification. For trace metal analysis, “repeat 5-6 injections and keep the RSD at 2% NMT" is difficult to achieve. The advantages and disadvantages of each instrumental analysis method are very obvious.

One important aspect to consider when comparing beclomethasone to other corticosteroids is the impurity profile of each medication. Several corticosteroids, including beclomethasone, have been evaluated for their impurity profiles. In general, the impurity profiles of corticosteroids depend on the synthetic route, starting materials, and purification methods used during the manufacturing process. Ciclesonide had a slightly different impurity profile, with one additional impurity: 21-chloro-17alpha-hydroxy-9alpha-fluoro-11beta-hydroxypregn-4-ene-3,20-dione. In conclusion, comparing the impurity profiles of corticosteroids can provide important information on the quality and safety of these medications.
