Patent Claims:	1. A method for treating chronic constipation in a human subject comprising orally administering to said human subject a composition consisting of a per unit dose of 3 mg or 6 mg of a peptide consisting of SEQ ID NO:1 wherein the peptide is a [4,12; 7,15] bicycle, an inert low moisture carrier, and a lubricant, and wherein the peptide has a chromatographic purity of no less than 91% after storage for at least three months. 2. The method of claim 1, wherein the constipation is associated with irritable bowel syndrome or chronic idiopathic constipation. 3. A method of treating or alleviating a symptom associated with chronic idiopathic constipation or irritable bowel syndrome in a human subject comprising orally administering to said human subject a composition consisting of a per unit dose of 3 mg or 6 mg of a peptide consisting of SEQ ID NO:1 wherein the peptide is a [4,12; 7,15] bicycle, an inert low moisture carrier, and a lubricant, and wherein the peptide has a chromatographic purity of no less than 91% after storage for at least three months. 4. The method of claim 3, wherein the symptom is constipation or abdominal pain. 5. The method of claim 1, further comprising administering to said patient an effective dose of an inhibitor of cGMP-dependent phosphodiesterase either concurrently or sequentially with said guanylate cyclase receptor agonist. 6. The method of claim 5, wherein said inhibitor of cGMP-dependent phosphodiesterase is selected from the group consisting of sulindac sulfone, zaprinast, and motapizone. 7. The method of claim 1, further comprising administering to said patient an effective dose of a laxative. 8. The method of claim 3, further comprising administering to said patient an effective dose of an inhibitor of cGMP-dependent phosphodiesterase either concurrently or sequentially with said guanylate cyclase receptor agonist. 9. The method of claim 8, wherein said inhibitor of cGMP-dependent phosphodiesterase is selected from the group consisting of sulindac sulfone, zaprinast, and motapizone. 10. The method of claim 3, further comprising administering to said patient an effective dose of a laxative. 11. The method of claim 1, wherein the inert low moisture carrier is microcrystalline cellulose. 12. The method of claim 1, wherein the lubricant is magnesium stearate. 13. The method of claim 1, wherein the inert low moisture carrier is microcrystalline cellulose and the lubricant is magnesium stearate. 14. The method of claim 3, wherein the inert low moisture carrier is microcrystalline cellulose. 15. The method of claim 3, wherein the lubricant is magnesium stearate. 16. The method of claim 3, wherein the inert low moisture carrier is microcrystalline cellulose and the lubricant is magnesium stearate.
