Understanding the effect of API changes in pharmaceutical processingMar 16th, 2022 at 14:15 Automobiles Ratnapura 107 views
The work not only demonstrates that the input API size was impacted by the process, but that by characterising the API particle characteristics one could understand the mechanism of the change. This improved understanding of the intermediate API/blend characteristics could be applied to subsequent processing steps, removing the requirement to rely on the input particle characterisation data.
Subsequent work4 utilised the measured API attrition to determine the location of attrition events within the feed system. These efforts applied the understanding of the process/API interaction in order to develop a better elucidation of the unit process and to investigate the impact of varying process conditions on the extent of attrition. The study demonstrated how changes in the feed screw speed could alter the extent of attrition; increased feed rates resulted in increased levels of attrition. This raises an interesting issue; for such unit processes the feed system is often utilised as part of the automated feedback control to maintain the intermediate product characteristics, but if by changing the feed system we alter the blend characteristics, the tool used to control process variation could be a significant source of said variation.
Active pharmaceutical ingredients (APIs) refer to vital chemicals that are responsible for making the drug work. Depending on type, biotech/biological API, synthetic chemical API, high-potency API, plant extracts API, and classical fermentation API are some of the products available in the active pharmaceutical ingredients (API) market.
