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.
Claims19
A transdermal drug administration patch comprising
- a drug delivery element comprising pellets, particles or granules of a sustained-release pharmaceutical composition embedded in a matrix, wherein the sustained-release pharmaceutical composition comprises an active pharmaceutical ingredient co-formedly interspersed within and homogeneously distributed throughout pores of a solid, continuous network,
- wherein the network
- comprises a carrier material based on one or more ceramics or one or more geopolymer materials;
- and
- possesses a mechanical strength sufficient to maintain the overall integrity of the network when a force of at least about 1 kg-force/cm2 (9 newtons/cm2) is applied thereto.
A transdermal drug administration patch comprising
- a drug delivery element comprising pellets, particles or granules of a sustained-release pharmaceutical composition embedded in a hydrogel, a fat or a pharmaceutically acceptable polymer, wherein the sustained-release pharmaceutical composition comprises an active pharmaceutical ingredient co-formedly interspersed within pores of a solid, continuous network,
- wherein the network
- comprises a carrier material based on one or more ceramics or one or more geopolymer materials;
- and
- possesses a mechanical strength sufficient to maintain the overall integrity of the network when a force of at least about 1 kg-force/cm2 (9 newtons/cm2) is applied thereto.
