Abstract: There is provided an inhalation device for delivering a deliverable agent in the form of an aerosol or vapour to a user. The device comprises a solid, porous carrier material having a defined porosity, and a deliverable agent located within the pores of the carrier material. The device is operable to heat the carrier material and vaporise the deliverable agent. Deliverable agents that may be delivered to the user include active pharmaceutical ingredients. Suitable materials for the porous carrier material include chemically bonded ceramic materials and geopolymeric materials.

Abstract: A transdermal drug administration device comprising a drug delivery element (10) defining a contact surface (12) for location, in use, against a patient's skin. The drug delivery element (10) 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.

Abstract: The present invention relates to a sustained release medical composition comprising an active pharmaceutical ingredient and a geopolymeric binder. Preferably the active pharmaceutical ingredient is combined with the geopolymeric binder during the formation of that binder.
