    摘要: New methods for the refolding of recombinant granulocyte colony stimulating factor (G-CSF) from inclusion bodies are disclosed. The methods comprise two refolding steps. In particular, the methods comprise the solubilizing of G-CSF with a solubilizing agent, the oxidative refolding (first refolding step) of G-CSF in the presence of the solubilizing agent and an oxidizing agent, the efficient removal of the solubilizing agent, and a second refolding step to complete the folding of G-CSF in the absence of the solubilizing agent. Various methods are described for the efficient removal of the solubilizing agent from partially refolded G-CSF.

    摘要: The present invention relates to a film-coated tablet containing drospirenone active agent, comprising a tablet core coated with a film-forming polymer layer with improved resistance against atmospheric humidity. The tablet core is obtainable by a process which comprises dissolving drospirenone in ethanol, then dripping the solution obtained onto the surface of the fluid bed in a fluidizing equipment without spraying pressure while controlling the temperature of the product obtained and removing the solvent molecules from the wet material by a hot airflow.
