Stabilizowana, wolna od HSA kompozycja farmaceutyczna, sposób zwiekszania rozpuszczalnosci interferonu beta (IFN-β), sposób wytwarzania wolnej od HSA kompozycji farmaceutycznej oraz kompozycja farmaceutyczna otrzymana tym sposobem
Stabilized pharmaceutical compositions comprising substantially monomeric interferon-beta (IFN-²) and methods useful in their preparation are provided. The compositions comprise the IFN-² solubilised in a low-ionic-strength formulation that maintains the composition at a pH of about 5.0. Methods for preparing these compositions, and for increasing solubility of IFN-² in pharmaceutical compositions, are provided.
