Olmesartan/amlodipine, sold under the brand name Azor, among others is a combination medication used to treat high blood pressure. It combines two antihypertensive agents in a film-coated tablet. It contains amlodipine, a calcium channel blocker, and olmesartan medoxomil, an angiotensin-2 receptor antagonist (ARB or A2A). The patent is held by Daiichi Sankyo Pharmaceuticals. Daiichi Sankyo filed a supplemental New Drug Application (sNDA) for Azor with the United States Food and Drug Administration on September 17, 2008.[1] Azor has been studied in clinical trials; one test showed it reduced blood pressure during a 24-hour period and was well tolerated.[2]


Azor is available in different dose preparations: 5 mg/20 mg, 10 mg/20 mg,5 mg/40 mg and 10/40 mg's of amlodipine and olmesartan respectively.[3] One investigation (which included doctors employed by Daiichi Sankyo) concluded that "From a pharmacokinetic perspective, the 2 drugs (amlodipine and olmesartan) are well suited to coadministration in a fixed-dose combination."[4]
