Edarbi (Azilsartan Medoxomil)
What Is A Generic?×
A generic drug is essentially a copycat version of a brand-name medication, offering the same safety, quality, and effectiveness, but often at a lower cost. When a brand-name drug's patent expires, other companies can produce the generic version. These generics contain the same active ingredients and work in the same way in the body as the original brand-name drug. However, they might differ in color, shape, or inactive ingredients. The appeal of generic drugs lies in their affordability; they provide a more cost-effective option for consumers without sacrificing the benefits of the original medication. This makes healthcare more accessible to a larger portion of the population, ensuring that more people can receive the treatment they need without the burden of high costs associated with brand-name drugs.
Edarbi, known generically as azilsartan medoxomil, is a potent and selective angiotensin II type 1 (AT1) receptor blocker. It exerts its effects by targeting and blocking the angiotensin II receptors, which are responsible for vasoconstriction and water retention. By doing so, Edarbi relaxes and widens the blood vessels, reducing the force against the vessel walls and lowering blood pressure.
Edarbi’s mechanism of action revolves around the renin-angiotensin-aldosterone system (RAAS), a critical regulator of blood pressure and fluid balance in the body. When blood pressure drops or blood volume decreases, the kidneys release an enzyme called renin into the bloodstream. Renin then converts angiotensinogen into angiotensin I. Further, an enzyme called angiotensin-converting enzyme (ACE) converts angiotensin I into angiotensin II, a potent vasoconstrictor.
Angiotensin II binds to AT1 receptors on blood vessels and triggers vasoconstriction, leading to elevated blood pressure. Additionally, it stimulates the release of aldosterone, which promotes sodium and water retention, further contributing to hypertension.
Edarbi effectively blocks the AT1 receptors, preventing angiotensin II from binding and exerting its vasoconstrictive effects. This action helps dilate blood vessels, lower blood pressure, and reduce the workload on the heart.
Edarbi is primarily prescribed to adults with essential hypertension, which is high blood pressure without an identifiable underlying cause. It is not indicated for pediatric patients. Physicians may also consider Edarbi for patients who have difficulty controlling their blood pressure with other antihypertensive medications or who experience adverse effects with alternative treatments.

What is Essential Hypertension?
Essential hypertension is a chronic medical condition characterized by consistently elevated blood pressure levels. Unlike secondary hypertension, which is caused by an underlying health issue, essential hypertension develops gradually over time without any identifiable cause. It typically affects adults and becomes more prevalent with age.
Essential hypertension occurs when the blood vessels narrow, leading to increased resistance in the arteries, which, in turn, forces the heart to pump harder to circulate blood throughout the body. As a result, the force exerted on the walls of the arteries increases, causing the blood pressure to rise.
Effectively managing essential hypertension is crucial in preventing complications and reducing the risk of heart disease, stroke, and other health issues. Treatment plans often include a combination of lifestyle changes and medications.
