What is Losartas?
Losartas is an angiotensin II receptor blocker (ARB) commonly used to treat high blood pressure (hypertension) and heart failure. It is also prescribed to protect the kidneys in diabetic nephropathy. Losartas works by blocking the action of angiotensin II, a hormone that causes blood vessels to constrict, thus helping to relax and widen blood vessels, lowering blood pressure and improving heart function.
How do I take Losartas?
Losartas can be taken with or without food. There are no specific food restrictions, but avoid high-potassium foods or supplements as Losartas can increase potassium levels. Take once daily, at the same time each day. Swallow the tablet whole, without crushing or chewing. Follow your doctor’s advice on potassium intake and other medications you may be taking.
For how long do I take Losartas?
Losartas is often a medicine you take for a long time, maybe even your whole life.
What disease or symptom is Losartas used for?
Losartas is indicated for treating hypertension (high blood pressure), heart failure, and diabetic nephropathy (kidney disease in diabetes). It’s also used to reduce the risk of stroke in patients with hypertension and left ventricular hypertrophy (enlarged heart). Losartas helps lower blood pressure and protect kidney function, improving overall cardiovascular health.
How long does it take for Losartas to start working?
Your blood pressure may go down in the first week of taking Losartas, but it may take up to 6 weeks to feel the full effects.
Is Losartas effective?
Evidence supporting Losartas’s effectiveness comes from clinical trials showing it significantly reduces blood pressure, improving cardiovascular outcomes. Studies like the Losartas Heart Failure Study demonstrated its ability to reduce symptoms and hospitalizations in heart failure patients. It also effectively protects kidney function in those with diabetic nephropathy and reduces the risk of stroke in high-risk patients.
How does one know if Losartas is working?
The benefit of Losartas is evaluated by regularly monitoring blood pressure to ensure it stays within the target range. In patients with heart failure or diabetic nephropathy, kidney function and creatinine levels are also monitored. Additionally, doctors may assess heart function and symptoms to determine if the medication is effectively improving overall cardiovascular health and reducing risks.
How does Losartas work?
Losartas works by blocking the action of angiotensin II, a hormone that constricts blood vessels and raises blood pressure. By blocking angiotensin II receptors, Losartas helps relax and widen blood vessels, which lowers blood pressure. This action improves heart function, reduces strain on the heart, and helps protect the kidneys, particularly in people with diabetes.
Who should avoid taking Losartas?
Losartas is contraindicated in pregnancy, particularly in the second and third trimesters, due to risks to the fetus. It should not be used in patients with severe liver impairment or allergy to the drug. Caution is advised for those with kidney problems, low blood pressure, or high potassium levels. Regular monitoring of blood pressure, kidney function, and potassium is important.
Can I take Losartas with other prescription drugs?
Significant interactions with Losartas include diuretics (e.g., spironolactone) which may increase the risk of low blood pressure or kidney problems. ACE inhibitors (e.g., enalapril) or renin inhibitors (e.g., aliskiren) can cause hyperkalemia and kidney issues. NSAIDs (e.g., ibuprofen) may reduce Losartas’s effectiveness and harm kidney function. Always consult your doctor about all medications you're taking.
Can Losartas be taken safely while pregnant?
Losartas is a medication that should not be taken by pregnant women. If taken during pregnancy, it can decrease the amount of fluid surrounding the developing baby, especially in the second and third trimesters. This can cause harm to the baby's kidneys and lungs, leading to long-term health issues. If you discover you are pregnant while taking Losartas, stop taking it and consult your doctor immediately.
Can Losartas be taken safely while breastfeeding?
It's usually okay to breastfeed while taking Losartas, but it's important to talk to your doctor first. However, if your baby was born prematurely, it's best to avoid taking Losartas. Your doctor can help you decide the best course of action.
Is Losartas safe for the elderly?
Losartas is a medicine for high blood pressure and kidney protection in people with type 2 diabetes. In studies, a smaller percentage of older people (65 and older) took part in the high blood pressure trials compared to the diabetes trials. Doctors found Losartas worked similarly well in both younger and older adults, but some older people might be more sensitive to it. It's important for doctors to check potassium levels in the blood regularly, and they may need to adjust the dose or stop the medicine if necessary.
How should I store Losartas?
To keep your Losartas medicine in good condition, store it properly. Put it in a container that closes tightly to keep out light. The temperature should stay between 59°F to 86°F (15°C to 30°C). Most importantly, keep it and all other medicines out of reach of children for safety.
