The present invention generally relates to compositions and methods for treatment of subjects in need of muscle growth, muscle repair, improved muscular and neuromuscular control, and treatments for neuromuscular and neurological disorders, including brain disorders. In some cases, the composition may include nitric oxide and/or peptides such as thyrotropin-releasing hormone (TRH) and/or GnRH (gonadotropin-releasing hormone). The nitric oxide and/or peptides 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 structures containing nitric oxide and/or peptide. 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, e.g., onto a location where muscle growth, muscle repair, or improved muscular and neuromuscular control is desired, or on another suitable portion of the skin. 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.

Compositions comprising nanoparticles are described herein. At least a portion of the nanoparticles comprises a lipid and/or polymer which is water-insoluble, and an agent incorporated in the lipid and/or polymer. The nanoparticles are optionally associated with a surface of water-soluble particles which comprise a water-soluble compound. The polymer is optionally a polyanhydride. Further described herein are processes for preparing such compositions, comprising contacting a solution comprising the lipid and/or polymer dissolved in a non-aqueous solvent with an anti-solvent (in which the lipid and/or polymer and agent are insoluble) which is miscible with the non-aqueous solvent. Further described herein are uses of the compositions for nasal administration, and devices configured for nasal administration of the composition upon atomization.

The present invention generally relates to compositions and methods for topical or transdermal delivery, and treatment of sexual dysfunction. The compositions can be used in a variety of applications, including treating erectile dysfunction or sexual dysfunction. 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, e.g., onto the penis, vulva, or other suitable portion of the skin. The composition can also be applied to a mucosal surface in some instances.
