Abstract
The aim of this study was to investigate if controlled ice nucleation with our previouly published method is applicable to highlyâconcentrated protein formulations of bovine serum albumin (100 mg/ml and 193.9 mg/ml) and a monoclonal antibody (161.2 mg/ml) and if positive effects on primary drying time as well as reconstitution times can be achieved. We observed that for both proteins, ice nucleation at a product temperature of â5 °C significantly reduced primary drying time. Furthermore, reconstitution times of the lyophilized cakes could be shortened, especially for the monoclonal antibody formulation with a reconstitution time of 5 minutes instead of 15 minutes. © 2013 Wiley Periodicals, Inc. and the American Pharmacists Association J Pharm Sci 102:3915-3919, 2013
