Claims23
A pharmaceutical syringe comprising a syringe barrel comprising an interior syringe barrel wall, a proximal opening configured to receive a plunger in contact with the interior syringe barrel wall, and an integrally formed outlet connectable to a needle, the syringe barrel containing a compressible porous matrix, wherein the compressible porous matrix contains a pharmaceutical suitable for administration into a human patient and wherein the pharmaceutical is in a soluble glass in the compressible porous matrix.
A method of producing a compressible porous matrix insert comprising
- contacting a compressible porous matrix with a solution of a glass-forming material, which solution contains a pharmaceutical for delivery into a patient, and
- drying the solution to form a glass in the compressible porous matrix, which glass comprises the pharmaceutical, wherein the compressible porous matrix is capable of being placed into a barrel of a pharmaceutical syringe comprising a syringe barrel comprising an interior syringe barrel wall, a proximal opening configured to receive a plunger in contact with the interior syringe barrel wall, and an integrally formed outlet at a distal end of the syringe barrel connectable to a needle.
