A transdermal drug administration device comprising a drug delivery element () defining a contact surface () for location, in use, against a patient's skin. The drug delivery element () includes a sustained-release pharmaceutical composition. The composition comprises a network of a carrier material having a high mechanical strength and an active pharmaceutical ingredient. The active pharmaceutical ingredient is co-formedly interspersed within pores in the solid, continuous network of the carrier material.

Transdermal drug administration device

There is provided a sustained-release pharmaceutical composition comprising a solid, continuous network comprising an excipient with a high mechanical strength, which network also comprises pores, within which pores is interspersed a mixture of an active ingredient and a film-forming agent, characterised in that said pores are formed during the production of the composition. Compositions of the invention find particularly utility as abuse-resistant formulations comprising opioid analgesics that may be employed in the treatment of chronic pain.
