Process Of Spray Drying Of Glp-1 Peptide
Patent No. EP3897582 (titled "Process Of Spray Drying Of Glp-1 Peptide") was filed by Novo Nordisk on Dec 20, 2019. The application was issued on Sep 11, 2024.
Patent Summary
A process for spray drying semaglutide, a GLP-1 peptide, that achieves improved yield by controlling the ratio of atomizing gas flow rate to feed flow rate. The process involves introducing the semaglutide solution into a spray dryer at a feed flow rate and introducing an atomizing gas at a flow rate that maintains a ratio of 1.0-1.7, independent of the apparatus used or outlet temperature. This optimized ratio enables reduced product loss and higher yield compared to conventional spray drying processes.
