B7-33 Nasal Spray
As an advanced delivery system, the B7-33 peptide nasal spray provides a patient-friendly, needle-free alternative to injections. This approach enables peptides to bypass digestive enzymes and move straight into the bloodstream via the nasal mucosa. The result is faster onset, improved efficiency, and higher reliability in both therapeutic and research applications. The convenience of nasal sprays also makes them ideal for repeated dosing protocols.
What is B7-33?
B7-33 is a synthetic peptide derived from the human hormone relaxin, designed to mimic its beneficial effects while minimizing unwanted side effects. It has gained attention for its potential in treating fibrotic diseases, cardiovascular conditions, and inflammation. B7-33 works by targeting the relaxin receptor (RXFP1), which plays a key role in reducing fibrosis (excessive tissue scarring) and promoting tissue repair.
One of its primary applications is in managing fibrotic conditions, such as pulmonary fibrosis, liver fibrosis, and kidney fibrosis, where it helps prevent or reverse tissue damage. Additionally, B7-33 has shown promise in cardiovascular health by improving blood vessel function, reducing inflammation, and protecting against heart failure. Its anti-inflammatory properties also make it a potential candidate for treating chronic inflammatory diseases.
With its targeted mechanism and favourable safety profile, B7-33 offers a promising therapeutic option for conditions involving fibrosis, inflammation, and cardiovascular dysfunction. Further research is ongoing to expand its applications, learn more here.
