Abstract

The invention relates to drug delivery devices for insertion into the vagina, rectum or nasal cavity comprising a body, a layer of fluid-impermeable material on at least part of said body and one or more pharmaceutical agents disposed on the surface of the material remote from said body, wherein said body comprises absorbent material. The devices exploit the highly vascularised nature of the vaginal, nasal and rectal mucosal tissue to deliver pharmaceutical agents to localised areas and/or into underlying tissues.
