Embodiments of the invention provide swallowable devices, preparations and methods for delivering drugs and other therapeutic agents within the GI tract. Many embodiments provide a swallowable device for delivering the agents. Particular embodiments provide a swallowable device such as a capsule for delivering drugs into the intestinal wall or other GI lumen. Embodiments also provide various drug preparations that are configured to be contained within the capsule, advanced from the capsule into the intestinal wall and degrade to release the drug into the bloodstream to produce a therapeutic effect. The preparation can be operably coupled to delivery means having a first configuration where the preparation is contained in the capsule and a second configuration where the preparation is advanced out of the capsule into the intestinal wall. Embodiments of the invention are particularly useful for the delivery of drugs which are poorly absorbed, tolerated and/or degraded within the GI tract.

1. A method for delivering a gonadotropin releasing hormone (GnRH) or a GnRH analogue dosage to a patient in need thereof, the method comprising: orally delivery in a capsule a solid GnRH or GnRH analogue dosage shaped as a tissue penetrating member; andpenetrating the tissue penetrating member into an intestinal wall from the capsule after oral ingestion of the capsule, wherein the GnRH or GnRH analogue is released into the blood stream from the solid dosage GnRH or GnRH analogue in the intestinal wall. 2. The method of claim 1, wherein the GnRH or GnRH analogue released into the blood stream from the solid dosage GnRH or GnRH analogue reaches a Cmax in a shorter time period than a time period to achieve a Cmax for an extravascularly injected dose of GnRH or GnRH analogue. 3. The method of claim 2, wherein a tmax for the GnRH or GnRH analogue released from the solid dosage GnRH or GnRH analogue is less than about 80% of a tmax for the extravascularly injected dose of GnRH or GnRH analogue. 4. The method of claim 2, wherein a tmax for the GnRH or GnRH analogue released from the solid dosage GnRH or GnRH analogue is less than about 50% of a tmax for the extravascularly injected dose of GnRH or GnRH analogue. 5. The method of claim 2, wherein a tmax for the GnRH or GnRH analogue released from the solid dosage GnRH or GnRH analogue is less than about 30% of a tmax for the extravascularly injected dose of GnRH or GnRH analogue. 6. The method of claim 2, wherein a tmax for the GnRH or GnRH analogue released from the solid dosage GnRH or GnRH analogue is less than about 10% of a tmax for the extravascularly injected dose of GnRH or GnRH analogue. 7. The method of claim 1, wherein the tissue penetrating member is inserted into a wall of the small intestine. 8. The method of claim 1, wherein penetrating the tissue penetrating member into the intestinal wall comprises operably coupling the tissue penetrating member to a delivery means having a first configuration wherein the tissue penetrating member is within the capsule, and a second configuration wherein the tissue penetrating member is advanced out of the capsule and into the intestinal wall. 9. The method of claim 8, wherein penetrating the tissue penetrating member into the intestinal wall comprises expanding at least one expandable balloon from the first to the second configuration. 10. The method of claim 1, wherein the solid dosage GnRH or GnRH analogue comprises a biodegradable material which degrades within the intestinal wall to release GnRH or GnRH analogue into the blood stream. 11. The method of claim 10, wherein the biodegradable material comprises PGLA, a sugar or maltose. 12. The method of claim 10, wherein the solid dosage GnRH or GnRH analogue comprises at least one pharmaceutical excipient. 13. The method of claim 12, wherein the at least one pharmaceutical excipient comprises at least one of a binder, a preservative or a disintegrant. 14. The method of claim 13, wherein the binder comprises PEG. 15. The method of claim 1, wherein a weight per cent of GnRH or GnRH analogue in the solid dosage GnRH or GnRH analogue comprises between about 2 to 15%. 16. The method of claim 1, wherein a dose of GnRH or GnRH analogue in the solid dosage GnRH or GnRH analogue is in a range from about 0.1 to 2.0. 17. The method of claim 16, wherein the dose of GnRH or GnRH analogue in the solid dosage GnRH or GnRH analogue is about 0.2 to 1.0 mg. 18. The method of claim 1, further comprising retaining the solid dosage GnRH or GnRH analogue within the intestinal wall after insertion. 19. The method of claim 18, wherein retaining comprises anchoring at least one of a barb or an inverse taper shape of the solid dosage GnRH or GnRH analogue in the intestinal tissue. 20. The method of claim 1, wherein penetrating the tissue penetrating member comprises applying a force to the tissue penetrating member, wherein the tissue penetrating member has sufficient stiffness to be advanced completely into the intestinal wall by such application of force. 21. The method of claim 1, wherein the solid dosage GnRH or GnRH analogue produces a long-term release of GnRH or GnRH analogue to produce a selectable t1/2. 22. The method of claim 21, wherein the t1/2 is about 12 hours. 23. The method of claim 1, wherein the Cmax achieved by delivering the solid dosage GnRH or GnRH analogue into the intestinal wall is at least about 10 times greater than the Cmax achieved when the preparation is delivered orally without insertion into the intestinal wall. 24. The method of claim 1, wherein the GnRH analogue is leuprorelin. 25. The method of claim 24, wherein a dose of leuprorelin in the preparation is in a range from about 0.1to 2 mg. 26. The method of claim 25, wherein, a dose of leuprorelin in the preparation is in a range from about 0.2to 1.0 mg.
