Peptide Nasal Sprays

In peptide therapy, specific chains of amino acids are formulated and administered to correct or modulate physiological functions. Peptides are very small, and they work by binding to receptors on cells, which triggers a response in the body. This could be anything from stimulating the release of growth hormone to increasing insulin sensitivity or suppressing inflammation. Peptides can be delivered in a number of ways, including injections and skin creams. Intranasal delivery can also be an effective option.

Peptide nasal sprays allow the compounds to bypass the digestive system and enter the bloodstream directly. Because of this, they can be more potent than other forms of delivery. They can help with a variety of conditions, including improving sleep quality and reducing fatigue. Moreover, peptides can also accelerate mold and chronic inflammatory response syndrome (CIRS) recovery. In fact, the latest research into peptide nasal sprays is promising. It has been found that a new compound called A1R-CT can significantly reduce the death of neurons in Alzheimer’s patients. The spray is able to do this by inhibiting neurabin, a protein that ensures the protective mechanism that tamps down the hyperexcitability of neurons that disrupts normal communication and produces seizures doesn’t overdo it. By doing so, the A1R-CT peptide allows the neurons to become more polarized, making them less likely to fire off excessive electrical signals that cause seizures.

Nasal delivery may be particularly useful for peptides because of its direct nose-to-brain pathway. This is especially true for peptides that are intended to be neuroprotective or modify neurotransmitter activity, such as bPC-157. BPC-157 is already being used in the treatment of brain swelling and traumatic injury, and it has been shown to significantly reduce brain swelling in animals.

The nose-to-brain delivery of peptides can be more effective than other drug administration methods due to the dense vasculature that connects the nasal cavity to the central nervous system (CNS). A recent study by Fransen et al. demonstrated that nasal delivery of the peptide desmopressin was able to deliver it to the CNS without crossing the BBB, and the concentrations of peptide in the CSF were comparable to those in the blood.

Moreover, the nasal dry powder formulation was more stable than the liquid and sublingual tablets that were studied. This may be because the dry powder formulation does not contain propellants or preservatives, which can negatively impact drug bioavailability. These findings suggest that the nasal dry powder formulation of peptides may be an ideal route for N-to-B delivery to the CNS. This route is particularly well suited to peptides that have broad clinical applications, such as insulin and oxytocin (OT). The scope and limitations of this approach are discussed in this article. N-to-B nasal delivery is a novel strategy for the targeted and efficient delivery of peptides to the CNS. However, further study is required to optimize the peptide formulations and nasal delivery devices for efficient CNS N-to-B transport. This may be particularly relevant in the context of developing peptides to treat neurodegenerative diseases such as Alzheimer’s and mental health conditions like schizophrenia. peptide nasal sprays
