Losartan vs. Lisinopril: What's the Difference?
Losartan is an ARB preventing blood vessel narrowing; lisinopril is an ACE inhibitor reducing blood pressure.
Losartan, a medication categorized as an Angiotensin II Receptor Blocker (ARB), primarily works by blocking the action of Angiotensin II, a natural substance that tightens blood vessels. This relaxation allows for easier blood flow and lower blood pressure. On the other hand, Lisinopril falls under the class of drugs known as ACE (Angiotensin-Converting Enzyme) inhibitors. It works by reducing the production of Angiotensin II, leading to relaxed blood vessels and, consequently, lowered blood pressure.
Losartan is often chosen for its role in protecting the kidney from the effects of diabetes, besides its fundamental function in controlling high blood pressure. Conversely, Lisinopril is frequently prescribed not only for high blood pressure but also for improving survival after a heart attack and for heart failure treatment, demonstrating its cardiovascular benefits.
The side effects of Losartan can include dizziness, upper respiratory infections, and more rarely, muscle cramps or weakness. In contrast, Lisinopril's side effects can be quite distinct, commonly causing a persistent dry cough, dizziness, and, in rare cases, angioedema, a serious swelling of deep skin layers.
In handling special conditions, Losartan is often considered safer for patients with a history of chronic kidney disease and is less likely to cause metabolic issues. Lisinopril, however, while beneficial for heart conditions, may not be suitable for individuals with a history of angioedema or women who are pregnant.
Patients on Losartan must avoid potassium supplements or salt substitutes containing potassium, as the drug can increase potassium levels. Lisinopril users, however, need to be more cautious about the possibility of angioedema and must inform healthcare professionals about any sudden swelling symptoms.

Why do some patients on lisinopril develop a dry cough?
Lisinopril can irritate the lungs, leading to a persistent dry cough as a common side effect.
Can lisinopril be used for conditions other than high blood pressure?
Yes, lisinopril is also used to treat heart disorders like heart attack recovery and heart failure.
What class of medication is losartan?
Losartan is an Angiotensin II Receptor Blocker (ARB).
What are the risks of taking lisinopril during pregnancy?
Lisinopril can harm or even be fatal to the developing fetus and is not recommended during pregnancy.
What are the common side effects of losartan?
Losartan may cause dizziness, upper respiratory infections, or increased potassium levels.
Can lisinopril be taken at night?
Yes, lisinopril can be taken at night, especially if it causes dizziness during the day.
Is losartan effective immediately?
Losartan may take several weeks to reach its full effect on blood pressure.
Can I drink alcohol while taking losartan?
It's best to limit alcohol since it can enhance losartan's side effects like dizziness.
What is the initial dosage for lisinopril?
The starting dose of lisinopril varies based on the condition, but it's often low and adjusted based on response.
How long does lisinopril stay in your system?
Lisinopril's effects can last for about 24 hours, and it may take several days to completely leave the body after stopping.
What happens if I miss a dose of losartan?
Take it as soon as you remember, or if it's almost time for the next dose, skip the missed one.
Is losartan suitable for patients with diabetes?
Yes, losartan is often used to protect kidney function in patients with diabetes.
What should patients avoid while taking losartan?
Patients on losartan should avoid potassium supplements or salt substitutes containing potassium.
Are there any foods lisinopril users should avoid?
No specific foods need to be avoided, but a balanced diet is recommended to maintain blood pressure control.
Can lisinopril cause facial swelling?
Yes, a rare side effect of lisinopril is angioedema, or deep tissue swelling, often in the face.
Does losartan interact with other medications?
Yes, losartan can interact with various drugs; patients should disclose all medications to their doctor.
Is it safe to exercise while taking lisinopril?
Yes, but start slow and don't overdo it; monitor your body's response to activity.
Can losartan increase potassium levels in the blood?
Yes, losartan can lead to higher potassium levels and intake should be monitored.
Is lisinopril safe for everyone with high blood pressure?
Most patients tolerate lisinopril well, but it may not be suitable for those with a history of angioedema or certain other conditions.
How does losartan affect heart health?
Losartan helps lower blood pressure and can reduce the risk of stroke in patients with an enlarged heart.
