Bradykinin is primarily involved in various physiological processes and has several therapeutic applications. It plays a significant role in regulating blood pressure by causing vasodilation, which helps in reducing hypertension. Additionally, bradykinin is used in research to study inflammation and pain mechanisms, as it induces these responses in the body. It is also investigated for its potential in treating conditions like angioedema and other vascular disorders. In clinical settings, bradykinin is sometimes utilized to assess endothelial function and vascular health. Furthermore, its role in mediating pain and inflammation makes it a target for developing analgesic and anti-inflammatory drugs.
