Solid drug formulation and device for storage and controlled delivery thereof
First Claim
1. A device for the storage and controlled release of a solid form of a drug comprising:
- a body portion;
one or more reservoirs located in and defined by the body portion;
a solid matrix which comprises a drug and which is contained in each of the one or more reservoirs; and
one or more excipient materials dispersed throughout pores or interstices within the solid matrix and substantially filling the space not otherwise occupied by the solid matrix within each of the one or more reservoirs, wherein the excipient material enhances stability of the drug while stored in the one or more reservoirs or enhances release of the drug from each reservoir.
