Losartan is a medicine used to lower blood pressure. Relaxing vessels to improve circulation, Losartan reduces strain on the heart and helps prevent cardiovascular issues.
Losartan belongs to a group of drugs called angiotensin II receptor blockers (ARBs), which stop a specific hormone from tightening blood vessels. It is the active ingredient in products such as Losartan and Hyzaar, and it is used to lower pressure and protect the heart.
Losartan is used to control high blood pressure (hypertension). It can also be part of the treatment plan for heart failure, where the heart has difficulty pumping blood efficiently. People with diabetes who have early kidney changes sometimes use it to slow further damage. In some patients, it may lower the chance of a stroke, especially when other risk factors are present.
After you swallow the tablet, the compound travels through your bloodstream and blocks the action of angiotensin II, a hormone that normally makes blood vessels narrow. By preventing this narrowing, the vessels stay relaxed, allowing blood to flow more easily and reducing the pressure your heart has to pump against.
If you are pregnant, planning to become pregnant, or are breastfeeding, use caution because this medicine can affect the developing baby. People with severe kidney or liver problems should also discuss risks with a health professional. Certain substances may interact with losartan, such as alcoholic beverages, other blood-pressure medicines, potassium-rich supplements, and non-steroidal anti-inflammatory drugs (NSAIDs); these can change how the drug works or raise potassium levels. Always check the specific medication's labeling for a full list of possible interactions.
Older adults and people with existing kidney disease often notice side effects more frequently. Those who take potassium-containing supplements or certain diuretics may have a higher chance of developing elevated potassium levels. Individuals with a history of allergic reactions to similar medicines should also be vigilant.
