Documented Uses

• Preparation: T. Naka, Y. Inada, European Patent Office patent 0520423; eidem, United States of America patent 5243054 (1992, 1993 both to Takeda).
• United States Food and Drug Administration–Approved Indications
• Azilsartan is an angiotensin II receptor blocker (ARB) used in the therapy of hypertension. It is associated with a low rate of transient serum aminotransferase elevations, but has yet to be linked to instances of acute liver injury.
• Breast Feeding; Lactation; Milk, Human; Antihypertensive Agents; Angiotensin II Type 1 Receptor Blockers; Angiotensin Receptor Blockers
• Angiotensin II Receptor Antagonists
• Edarbi is an angiotensin II receptor blocker (ARB) indicated for the treatment of hypertension to lower blood pressure. Lowering blood pressure reduces the risk of fatal and nonfatal cardiovascular events, primarily strokes and myocardial infarctions. These benefits have been seen in controlled trials of antihypertensive drugs from a wide variety of pharmacologic classes, including the class to which this drug principally belongs. /Included in US product label/
