Used in research as a selective antagonist for the angiotensin II receptor subtype 2 (AT2). It helps investigate the physiological and pathophysiological roles of the AT2 receptor in cardiovascular, renal, and neurological systems. Commonly applied in experimental models to study blood pressure regulation, tissue injury, inflammation, and fibrosis. Due to its specificity, it allows scientists to differentiate AT2-mediated effects from those involving the AT1 receptor. Primarily intended for in vitro and in vivo research; not approved for clinical or therapeutic use in humans.
