Abstract: A pharmaceutical aerosol is disclosed which is suitable for delivering an active compound to the mucosa of the nose, the osteomeatal complex or a paranasal sinus. The pressure of the aerosol is not constant, but pulsates at a frequency from about 10 to 90 Hz. The aerosol is further characterised in that it exhibits a low effective flow rate of less than about 5 liters per minute. The aerosol is, inter alia, suitable for the prevention, management, or treatment of a disease, symptom, or condition affecting the nose or the paranasal sinuses, such as acute and chronic sinusitis.

Abstract: The invention relates to a method for producing a purified solution containing L-cysteine from a fermentation broth containing L-cysteine. In said method, the fermentation broth containing L-cysteine, at a pH value from pH 6 to 9, is brought in contact with a basic anion exchanger, wherein the L-cysteine bonds to the anion exchanger. The anion exchanger is then rinsed with a first washing solution, and the bonded L-cysteine is removed from the anion exchanger by means of an acid and transferred into an eluate. Said eluate, having a pH?4, is brought in contact with an acidic cation exchanger, wherein the L-cysteine bonds to the cation exchanger. The cation exchanger is rinsed with a second washing solution, and the bonded L-cysteine is removed from the cation exchanger by means of a strong acid.
