Composition For Nasal Application With Improved Stability

Patent No. EP2818163 (titled "Composition For Nasal Application With Improved Stability") was filed by Maria Clementine Martin Klosterfrau Vertriebsgesellschaft on Sep 25, 2012. The application was issued on Jun 26, 2024.

Patent Summary

A pharmaceutical composition for treating rhinitis that provides enhanced stability through the use of a preservative system. The composition contains a combination of an imidazoline-based alpha-sympathomimetic and pantothenic acid, with the alpha-sympathomimetic component being a physiologically acceptable salt of xylometazoline. The preservative system, which includes benzalkonium chloride, enables the formulation to maintain its active ingredient concentrations while preventing degradation. This composition is particularly effective for topical intranasal applications, including nasal sprays and nasal drops, and is suitable for treating acute and chronic rhinitis.
