'''Eprosartan''' is an [[angiotensin II receptor antagonist]] used primarily for the treatment of [[hypertension]]. It is part of the class of medications known as [[angiotensin receptor blockers]] (ARBs), which work by blocking the action of [[angiotensin II]], a hormone that causes blood vessels to constrict.
Eprosartan is associated with a low rate of transient serum aminotransferase elevations but has yet to be linked to instances of acute liver injury.

==Pharmacology==
Eprosartan (ep" roe sar' tan) is an angiotensin II receptor blocker (ARB) used alone or in combination with other agents for therapy of hypertension. 
Eprosartan functions by selectively blocking the binding of angiotensin II to the [[angiotensin II receptor type 1]] (AT1 receptor) in various tissues, including vascular smooth muscle and the adrenal gland. This action leads to vasodilation and a reduction in blood pressure.
Eprosartan inhibits the renin-angiotensin system by blocking the angiotensin II type 1 receptor (AT1), which prevents the vasoconstriction and volume expansion induced by circulating angiotensin II thus accounting for its antihypertensive activity.

===Mechanism of Action===
Eprosartan was approved for use in the United States in 1997 for the treatment of hypertension.  
[[File:Eprosartan.svg|thumb|left|Structural formula of Eprosartan]]
Eprosartan inhibits the effects of angiotensin II by preventing its binding to the AT1 receptor. Angiotensin II is a potent vasoconstrictor and a key component of the [[renin-angiotensin system]], which regulates blood pressure and fluid balance. By blocking this pathway, eprosartan reduces peripheral vascular resistance and lowers blood pressure.


{{dose}}
===Pharmacokinetics===
Eprosartan is available in 400 and 600 mg tablets generically and under the trade name Teveten. The typical dose in adults in 400 to 800 mg daily in one or two divided doses, and it is used long term. Eprosartan is also available in fixed combinations with hydrochlorothiazide (Teveten HCT).
Eprosartan is administered orally and is absorbed through the gastrointestinal tract. It has a bioavailability of approximately 13% and reaches peak plasma concentrations within 1 to 2 hours after ingestion. The drug is primarily excreted unchanged in the urine and feces.

==Clinical Use==
Side effects are uncommon, but can include headache, dizziness, fatigue, edema, cough, gastrointestinal upset, and fetal toxicity.  Many ARBs including eprosartan have been linked to rare instances of a severe sprue-like enteropathy that presents with chronic diarrhea and weight loss and villous flattening and atrophy on intestinal biopsy. The diarrhea usually arises after 6 months or more of therapy and does not respond to corticosteroids or a gluten-free diet, but does resolve promptly with stopping eprosartan.  This adverse side effect is most common wtih olmesartan.
Eprosartan is indicated for the management of hypertension. It may be used alone or in combination with other antihypertensive agents, such as [[diuretics]] or [[calcium channel blockers]].

===Dosage and Administration===
The typical starting dose of eprosartan is 600 mg once daily. The dose may be adjusted based on the patient's response and clinical condition. It is important to monitor blood pressure regularly to ensure optimal control.

==Side Effects==
Common side effects of eprosartan include dizziness, headache, and fatigue. These effects are generally mild and transient. Serious adverse effects are rare but may include [[angioedema]] and [[renal impairment]].

Eprosartan is an angiotensin II receptor antagonist used primarily for the treatment of hypertension. It is part of the class of medications known as angiotensin receptor blockers (ARBs), which work by blocking the action of angiotensin II, a hormone that causes blood vessels to constrict.

Pharmacology[edit]

Eprosartan functions by selectively blocking the binding of angiotensin II to the angiotensin II receptor type 1 (AT1 receptor) in various tissues, including vascular smooth muscle and the adrenal gland. This action leads to vasodilation and a reduction in blood pressure.

Mechanism of Action[edit]

Structural formula of Eprosartan

Eprosartan inhibits the effects of angiotensin II by preventing its binding to the AT1 receptor. Angiotensin II is a potent vasoconstrictor and a key component of the renin-angiotensin system, which regulates blood pressure and fluid balance. By blocking this pathway, eprosartan reduces peripheral vascular resistance and lowers blood pressure.

Pharmacokinetics[edit]

Eprosartan is administered orally and is absorbed through the gastrointestinal tract. It has a bioavailability of approximately 13% and reaches peak plasma concentrations within 1 to 2 hours after ingestion. The drug is primarily excreted unchanged in the urine and feces.

Clinical Use[edit]

Eprosartan is indicated for the management of hypertension. It may be used alone or in combination with other antihypertensive agents, such as diuretics or calcium channel blockers.

Dosage and Administration[edit]

The typical starting dose of eprosartan is 600 mg once daily. The dose may be adjusted based on the patient's response and clinical condition. It is important to monitor blood pressure regularly to ensure optimal control.

Side Effects[edit]

Common side effects of eprosartan include dizziness, headache, and fatigue. These effects are generally mild and transient. Serious adverse effects are rare but may include angioedema and renal impairment.

Contraindications[edit]

Eprosartan is contraindicated in patients with known hypersensitivity to the drug or any of its components. It should not be used during pregnancy due to the risk of fetal harm.
