Table of contents:

Benicar (Olmesartan Medoxomil) is a medication prescribed to treat high blood pressure, or hypertension. It belongs to the family of drugs known as angiotensin receptor blockers (ARBs). Benicar works by blocking the action of certain natural substances that tighten and narrow blood vessels, thereby allowing blood to flow more freely. This, in turn, lowers blood pressure and helps to reduce the risk of stroke and heart attack.

Olmesartan medoxomil is an angiotensin II receptor antagonist used to treat hypertension in adults and children six years of age and older. Lowering blood pressure reduces the risk of fatal and nonfatal cardiovascular events, primarily strokes and myocardial infarctions. By reducing blood pressure, the risk of these conditions can be minimized, and the overall health of the patient improved.

Uses and Dosage

Benicar (olmesartan) comes in the form of tablets. It is available in three different prescription strengths: 10 milligrams, 20 milligrams, and 40 milligrams. The tablets are imprinted with the words "SANKYO" and "C15". The dosage must be individualized to achieve the desired therapeutic effect.

The usual recommended starting dose of Benicar for adults with hypertension is 20 mg once daily when used as monotherapy. For patients requiring further reduction in blood pressure after 2 weeks of therapy, the dose of Benicar may be increased to 40 mg. Doses above 40 mg do not appear to have a greater effect, and twice-daily dosing offers no advantage over the same total dose given once daily.

For pediatric patients aged 6 years and older with hypertension, the recommended starting dose of Benicar is 10 mg once daily for patients who weigh 20 to <35 kg (44 to 77 lb), or 20 mg once daily for patients who weigh ≥35 kg. If further reduction in blood pressure is needed after 2 weeks of therapy, the dose of Benicar may be increased to a maximum of 20 mg once daily for patients who weigh <35 kg or 40 mg once daily for patients who weigh ≥35 kg.
