Abstract

The goals of this work were to evaluate if high-speed electrospinning can be used as a gentle and continuous drying technology to produce protein-containing cyclodextrin-based fibers from an aqueous solution and to convert the produced protein-cyclodextrin fibers into a directly compressible powder. A 400 mL/h feeding rate was used during the electrospinning experiments, corresponding to a ~270 g/h production rate of the dried material. The produced fibers were collected in a cyclone. The fibers were found grindable without secondary drying, and the ground powder was mixed with tableting excipients and was successfully tableted by direct compression. The model protein-type drug (β-galactosidase) remained stable during each of the processing steps (electrospinning, grinding, tableting) and after 6 months of storage at room temperature in the tablets. The obtained results demonstrate that high speed electrospinning can be a gentle alternative to traditional drying methods used for protein-type drugs, and that tablet formulation is achievable from the electrospun material prepared this way.
