Angiotensin Receptor Blockers (ARBs) »
The class of drugs called angiotensin receptor blockers (ARBs), as the class name suggests, are drugs that block the action of angiotensin. Specifically, ARBs prevent angiotensin II from binding to the angiotensin II receptor on blood vessels and other tissues.
Angiotensin II is a very potent chemical that causes the muscles surrounding blood vessels to contract, thereby narrowing the blood vessels. Narrowing of blood vessels increases the pressure within the blood vessels and may lead to high blood pressure (hypertension). Reducing the binding and activity of angiotensin II leads to widening (dilation) of blood vessels and reduces blood pressure. By lowering blood pressure against which the heart must pump, the amount of work that the heart must do is reduced. ACE inhibitors also reduce blood pressure in the kidneys, slowing the progression of kidney disease due to high b...

Hydrochlorothiazide is a thiazide diuretic (water pill) that helps prevent your body from absorbing too much salt, which can cause fluid retention.
Eprosartan is in a group of drugs called angiotensin II receptor antagonists. Eprosartan keeps blood vessels from narrowing, which lowers blood pressure and improves blood flow.
The combination of hydrochlorothiazide and eprosartan is used to treat high blood pressure (hypertension).
Hydrochlorothiazide and eprosartan may also be used for other purposes not listed in this medication guide.
Get emergency medical help if you have any of these signs of an allergic reaction: hives; difficulty breathing; swelling of your face, lips, tongue, or throat.
In rare cases, hydrochlorothiazide and eprosartan can cause a condition that results in the breakdown of skeletal muscle tissue, leading to kidney failure. Call your doctor right away if you have muscle pain, tenderness, or weakness especially if you also have fever, nausea or vomiting, and dark colored urine.
Call your doctor at once if you have any other serious side effects, such as:

This is not a complete list of side effects and others may occur. Call your doctor for medical advice about side effects. You may report side effects to FDA at 1-800-FDA-1088.
Do not use this medication without telling your doctor if you are pregnant. Eprosartan may cause injury and even death to the unborn baby if you take it during the second and third trimesters of pregnancy. Use an effective form of birth control. Stop using this medication and tell your doctor right away if you become pregnant during treatment.
Hydrochlorothiazide and eprosartan can cause side effects that may impair your thinking or reactions. Be careful if you drive or do anything that requires you to be awake and alert.
Avoid drinking alcohol. It can lower your blood pressure and may increase some of the side effects of hydrochlorothiazide and eprosartan.
In rare cases, hydrochlorothiazide and eprosartan can cause a condition that results in the breakdown of skeletal muscle tissue, leading to kidney failure. Call your doctor right away if you have muscle pain, tenderness, or weakness especially if you also have fever, nausea or vomiting, and dark colored urine.
