By way of example, sugars like sucrose or mannitol, will often be utilised as cryoprotectants to stabilize the composition of proteins for the duration of freezing. They prevent the denaturation or aggregation of your API, which Specifically crucial for elaborate molecules like biologics but Conversely they might influence the drug solution behavior throughout sublimation and thus a deep knowledge of how formulation can affect lyophilization process is important.
Protocols for lyophilization and their efficacy for different samples. Representative graphs and reference protocols with correct time, temperature, and pressure values indicated for each period employed for: a kidney, heart, liver, and lung tissue samples; b aorta and pores and skin tissue samples; c peritoneal dialysis fluid focus; d liquid removal from fecal samples.
