Also known as Olmesartan
Olmesartan medoxomil is an angiotensin-II receptor antagonist (ARB) that potently and selectively inhibits the biological effects of Angiotensin-II. It blocks the actions of Angiotensin-II via the AT1 receptor, irrespective of the biochemical pathway leading to Angiotensin-II formation. This action reduces Angiotensin-II induced vasoconstriction, aldosterone secretion, thirst, vasopressin release, and cellular hypertrophy, thereby decreasing arterial blood pressure.
May lower fetal heart rate. Avoid oral use

Increased risk of hypotension, hyperkalemia, and renal impairment.
Avoid concomitant use.
Increased risk of hypotension, hyperkalemia, and renal impairment (including acute renal failure) compared to monotherapy.
CONTRAINDICATED in patients with diabetes or renal impairment (GFR < 60 mL/min/1.73 m2). Avoid in all other patients.
Greater incidence of acute kidney injury (AKI) and adverse cardiac events.
The combination of these two classes should be avoided.

Increased worsening of renal function, hypotension, syncope, and hyperkalemia without increased efficacy.
Not recommended for the treatment of hypertension. Previous studies indicate more harm than benefit.
