Zusammenfassung:	The present disclosure provides a foam nasal dressing for topically administering an active agent to a nasal cavity and for absorbing fluid discharge. The foam nasal dressing comprises a foamed core portion and a foamed shell portion arranged such that the foamed core portion is at least partially disposed within the foamed shell portion. The foamed shell portion has a porosity of greater than 80% and comprises a first phase-separated polymer and an active agent. The foamed core portion comprises a second phase-separated polymer with the first and second phase-separated polymers being the same or different. The present disclosure also provides a method of forming the foam nasal dressing.
