What is losartan used for?
Losartan is a medication prescribed to treat high blood pressure (hypertension) [3].

Additionally, losartan can reduce the risk of stroke in patients with high blood pressure and an enlarged heart [3].
How does losartan work?
Losartan belongs to a class of drugs called angiotensin II receptor blockers (ARBs) [3]. It works by relaxing blood vessels, which lowers blood pressure and allows the heart to pump blood more easily [3].
What are the side effects of losartan?
Common side effects of losartan can include dizziness, tiredness, and upper respiratory tract infection symptoms [4]. Less common side effects may involve stomach pain, heartburn, diarrhea, muscle pain, and insomnia [4]. Serious side effects, though rare, can include signs of kidney problems, high potassium levels, or allergic reactions [4].
What is the difference between losartan and other blood pressure medications?
Losartan is an ARB, distinct from other classes of blood pressure medications such as ACE inhibitors, calcium channel blockers, or beta-blockers. These different classes work through various mechanisms to lower blood pressure [5]. ARBs like losartan specifically block the action of angiotensin II, a hormone that constricts blood vessels [5].
Where can I find generic losartan pricing?
Pricing for generic losartan can vary based on the manufacturer, dosage, and the pharmacy where it is purchased [1]. Online pharmacies and local drugstores often provide competitive pricing, and comparing options can help find the most affordable generic losartan [1].
Are there alternatives to losartan for high blood pressure?
Yes, there are several alternative medications for high blood pressure, including other ARBs, ACE inhibitors, calcium channel blockers, beta-blockers, and diuretics, among others [5]. The choice of medication depends on individual patient needs and medical conditions [5].
What do patients need to know about taking losartan?
Patients taking losartan should inform their doctor about any other medical conditions they have, especially kidney disease, liver disease, or heart failure [4]. It is also important to disclose all other medications, supplements, and herbal products being taken, as interactions can occur [4]. Pregnant women should not take losartan [4].
What is the mechanism of action for losartan?
Losartan acts by blocking the binding of angiotensin II to its receptor in blood vessels and other tissues [3]. Angiotensin II is a potent vasoconstrictor that also stimulates aldosterone secretion, leading to sodium and water retention [3]. By blocking its effects, losartan causes vasodilation and reduces sodium and water reabsorption, thereby lowering blood pressure [3].
