Irbesartan and losartan are both commonly prescribed medications for treating high blood pressure. While they belong to the same class of drugs known as angiotensin II receptor blockers (ARBs), there are key differences between the two medications that you should be aware of.
Irbesartan works by blocking the action of angiotensin II, a hormone that constricts blood vessels, thereby lowering blood pressure. Losartan, on the other hand, also blocks angiotensin II but has been found to have a longer duration of action compared to irbesartan.
Choosing between irbesartan and losartan may depend on your specific health needs and any existing medical conditions you may have. Consult with your healthcare provider to determine which medication is best suited for you.

Irbesartan Overview
Irbesartan is an angiotensin II receptor antagonist used primarily to treat high blood pressure, heart failure, and diabetic nephropathy. It works by blocking the action of angiotensin II, a hormone that causes blood vessels to constrict and raises blood pressure. Irbesartan relaxes and widens blood vessels, lowering blood pressure and improving blood flow. It is often prescribed to patients who cannot tolerate ACE inhibitors due to side effects like cough.
- Trade names: Avapro, Aprovel
- Dosage forms: Tablets
- Dosage strengths: 75mg, 150mg, 300mg
Irbesartan Overview
Irbesartan is a medication commonly prescribed to treat high blood pressure. It belongs to a class of drugs known as angiotensin receptor blockers (ARBs). These medications work by blocking the action of angiotensin II, a hormone that causes blood vessels to constrict, leading to increased blood pressure.
Irbesartan helps to relax blood vessels, allowing blood to flow more easily, which helps to lower blood pressure and reduce the risk of heart attack and stroke.
Irbesartan is usually taken orally in the form of a tablet, and the dosage may vary depending on the individual’s condition and response to treatment. It is important to follow the prescribed dosage and instructions provided by your healthcare provider.
Common side effects of irbesartan may include dizziness, lightheadedness, or upset stomach. In rare cases, more severe side effects such as kidney problems or allergic reactions may occur. It is important to seek medical attention if you experience any unusual symptoms while taking irbesartan.
Overall, irbesartan is an effective medication for managing high blood pressure and reducing the risk of cardiovascular events. It is important to discuss with your healthcare provider about the benefits and potential risks of irbesartan before starting this medication.
Losartan Overview
Losartan is a medication commonly prescribed to treat high blood pressure (hypertension). It belongs to a class of drugs known as angiotensin II receptor blockers (ARBs). Losartan works by blocking the action of angiotensin II, a substance in the body that narrows blood vessels and increases blood pressure.
Key Points:
- Losartan is used to treat hypertension and lower the risk of stroke in certain patients.
- It is also indicated for the treatment of diabetic nephropathy in patients with type 2 diabetes.
- Losartan can help lower blood pressure and improve blood flow, reducing the workload on the heart.
Overall, Losartan is a widely used and effective medication for managing high blood pressure and related conditions. It is generally well-tolerated, but like any medication, it may cause side effects in some individuals. It’s essential to follow your healthcare provider’s guidance when taking Losartan and to report any unusual symptoms or concerns.

Mechanism of Action
Irbesartan and losartan belong to a class of medications known as angiotensin receptor blockers (ARBs). Both drugs work by blocking the action of angiotensin II, a hormone that causes blood vessels to constrict and raises blood pressure. By blocking angiotensin II, these medications help relax blood vessels, lower blood pressure, and improve blood flow to the heart and other organs.
Irbesartan specifically blocks the angiotensin II type 1 receptor, while losartan blocks both the type 1 and type 2 receptors. This difference in receptor specificity may result in slightly different effects and side effect profiles between the two medications.
Overall, the mechanism of action of irbesartan and losartan is similar, with both drugs effectively treating high blood pressure and certain other cardiovascular conditions by blocking the effects of angiotensin II.
Indications for Use
Irbesartan and losartan are both angiotensin II receptor blockers (ARBs) used to treat high blood pressure and certain types of heart failure. They are commonly prescribed to patients who cannot tolerate ACE inhibitors.
Irbesartan:
- Treatment of hypertension (high blood pressure) in adults and children over 6 years old
- Reduction of the risk of stroke in patients with hypertension and left ventricular hypertrophy
- Treatment of diabetic nephropathy in type 2 diabetic patients with hypertension and renal disease
Losartan:
- Treatment of hypertension in adults and children over 6 years old
- Reduction of the risk of stroke in patients with hypertension and left ventricular hypertrophy
- Treatment of diabetic nephropathy in type 2 diabetic patients with proteinuria
- Prevention of new-onset atrial fibrillation in patients with heart failure and left ventricular dysfunction
It is important to follow the prescribed dosage and instructions given by your healthcare provider when taking irbesartan or losartan for these indications.
Side Effects and Safety Profile
Irbesartan:
Irbesartan is generally well-tolerated, but like any medication, it can cause side effects. Common side effects of irbesartan include dizziness, headache, fatigue, and diarrhea. More serious side effects may include low blood pressure, kidney problems, and allergic reactions. It is important to consult your healthcare provider if you experience any of these symptoms.
Safety profile:
Irbesartan should not be taken during pregnancy as it may harm the unborn baby. It is also important to avoid alcohol and certain over-the-counter medications while taking irbesartan, as they can interact with the medication and increase the risk of side effects.
Losartan:
Losartan is generally well-tolerated, but some individuals may experience side effects. Common side effects of losartan include dizziness, chest pain, and cough. More serious side effects may include hypotension, hyperkalemia, and renal impairment. It is important to seek medical attention if you experience any severe side effects.
Safety profile:
Losartan should not be taken during pregnancy as it may cause harm to the fetus. It is also important to avoid potassium supplements and salt substitutes while taking losartan, as they can increase the risk of hyperkalemia.
