abstract: Neuropathic pain, including post-herpetic neuralgia after shingles, is not well controlled by existing treatments. EMA401 is an angiotensin II type 2 receptor antagonist developed in the search for antihypertensive drugs. The renin-angiotensin system has roles outside the cardiovascular system, including in the central and peripheral nervous systems.
