ABSTRACT
Budesonide is the 16alpha,17alpha-acetal of 16alpha-hydroxyprednisolone with n-butyraldehyde, endowed with anti-inflammatory activity. In a sample of budesonide tablets, kept for 3 years at 25 degrees C and 60% RH unknown impurities, not reported in European Pharmacopoiea, were present. Their identification was achieved by means of chemical and spectroscopic methods.
