The development of antidepressant peptides is also being facilitated by advancements in drug delivery. For instance, a nasal spray that delivers a peptide to treat depression holds promise as a potential alternative therapeutic approach, offering a non-invasive way to administer these compounds. Cell penetrating peptides are also a significant innovation, as they may provide therapy to those with treatment resistant depression by enhancing the delivery of therapeutic agents across cell membranes.

While the focus is on novel peptides, it's worth noting that some traditional approaches also interact with peptide systems. For example, saffron extracts also modulate hypothalamic peptides such as arginine vasopressin and corticotropin-releasing hormone, contributing to their known antidepressant effects. Similarly, while methylene blue is a monoamine oxidase (MAO) inhibitor, a class of drugs used to treat depression, its mechanism of action and potential interactions with peptide systems warrant further investigation.
