Abstract

The present invention generally relates to compositions and methods for topical or transdermal delivery. The compositions can be used in a variety of applications. In some cases, the composition may include nitric oxide and/or peptides. The nitric oxide and/or peptide may be present within a first phase comprising a lecithin, such as phosphatidylcholine. In certain embodiments, the lecithin is present in liposomes, micelles, or other vesicles containing nitric oxide, peptides, or both. The composition can take the form of a gel, a cream, a lotion, an ointment, a solution, a solid “stick,” etc., that can be rubbed or sprayed onto the skin. The composition can also be applied to a mucosal surface in some instances. Other aspects of the present invention are generally directed to methods of making or using such compositions, methods of promoting such compositions, kits including such compositions, or the like.

Claims

1. A composition for transdermal delivery of a peptide and nitric oxide, comprising:

a composition comprising lecithin, a peptide, and molecular nitric oxide, wherein the composition is stable at room temperature, and wherein the lecithin entraps the molecular nitric oxide.

2. The composition of claim 1, wherein the composition further comprises polyenylphosphatidylcholine.

3. The composition of claim 1, wherein the composition comprises a liquid crystal structure.

4. The composition of claim 1, wherein the composition comprises no more than about 250 ppm of water by weight of the composition.

5. The composition of claim 1, wherein the lecithin is present at at least about 0.25% by weight of the composition.

6. The composition of claim 1, wherein the molecular nitric oxide is present at at least about 0.5% by weight of the composition without nitric oxide.

7. The composition of claim 1, wherein the molecular nitric oxide is present within the composition as a gas.

8. The composition of claim 1, wherein the molecular nitric oxide is bound by hydrogen bonds or van der Waals forces to the lecithin.

9. The composition of claim 1, wherein the composition is a cream.

10. The composition of claim 1, wherein the composition is a gel.

11. A composition for transdermal delivery of a peptide and nitric oxide, comprising:

a composition comprising lecithin, a peptide, and molecular nitric oxide, wherein the composition comprises no more than about 250 ppm of water by weight of the composition and wherein the lecithin entraps the molecular nitric oxide.

12. The composition of claim 11, wherein the composition further comprises polyenylphosphatidylcholine.

13. The composition of claim 11, wherein the composition comprises a liquid crystal structure.

14. The composition of claim 11, wherein the composition is stable at room temperature.

15. The composition of claim 11, wherein the lecithin is present at at least about 0.25% by weight of the composition.

16. The composition of claim 11, wherein the molecular nitric oxide is present at at least about 0.5% by weight of the composition without nitric oxide.

17. The composition of claim 11, wherein the molecular nitric oxide is present within the composition as a gas.

18. The composition of claim 11, wherein the molecular nitric oxide is bound by hydrogen bonds or van der Waals forces to the lecithin.

19. The composition of claim 11, wherein the composition is a cream.

20. The composition of claim 11, wherein the composition is a gel.
