These include captopril (Capotene), beazrpri (Lotensin), enalapril (Vasotec), and lisinopril (Zestril), and are commonly used to treat blood pressure and heart disease.

Bradykinin is also thought to be the cause of the dry cough in some patients on widely prescribed angiotensin-converting enzyme (ACE) inhibitor drugs. It is thought that bradykinin is converted to inactive metabolites by ACE, therefore inhibition of this enzyme leads to increased levels of bradykinin; increased bradykinin sensitizes somatosensory fibers and thus causes hyperalgesia.
