Mechanism of action

Mechanism of action

Losartan belongs to a class of medications known as angiotensin II receptor blockers (ARBs). It works by blocking the action of angiotensin II, a substance in the body that causes blood vessels to constrict. By blocking the effects of angiotensin II, losartan relaxes and dilates blood vessels, which helps to lower blood pressure and improve blood flow.

Angiotensin II is also involved in the regulation of fluid and salt balance in the body. By blocking its action, losartan helps to reduce the workload on the heart and kidneys, which can be beneficial for people with conditions such as high blood pressure or heart failure.

Mechanism of action

The main mechanism of action of losartan is its ability to block the angiotensin II receptor. Angiotensin II is a hormone that constricts blood vessels, leading to increased blood pressure. By blocking the angiotensin II receptor, losartan helps dilate blood vessels and lower blood pressure.

Additionally, losartan also helps to reduce the secretion of aldosterone, a hormone that can contribute to fluid retention and high blood pressure. By inhibiting aldosterone, losartan can help the body excrete excess sodium and water, further lowering blood pressure.


One of the key benefits of losartan is its ability to lower blood pressure effectively. By blocking the action of angiotensin II, a hormone that constricts blood vessels, losartan helps to relax and widen the blood vessels, reducing the pressure within them. This can lead to a decrease in overall blood pressure levels, which is essential for individuals with hypertension or other cardiovascular conditions.

Lower blood pressure

One of the key benefits of losartan is its ability to lower blood pressure effectively. By blocking the action of angiotensin II, a hormone that narrows blood vessels, losartan helps the blood vessels to relax and widen, reducing the pressure in the arteries. This process allows the heart to pump blood more efficiently, decreasing the strain on the cardiovascular system and lowering the risk of heart-related complications.

Patients taking losartan may notice a gradual decrease in their blood pressure readings over time, which can help manage conditions such as hypertension and reduce the risk of strokes, heart attacks, and other cardiovascular issues. It is essential to follow your healthcare provider’s recommendations and monitor your blood pressure regularly while on losartan therapy to achieve optimal results and maintain a healthy blood pressure level.

Protection of the kidneys

The losartan drug not only helps to lower blood pressure and treat hypertension but also plays a crucial role in protecting the kidneys. By blocking the action of angiotensin II, losartan helps to dilate blood vessels, improving blood flow to the kidneys.
