Losartan potassium is a drug primarily used to treat high blood pressure (hypertension) and certain heart conditions. It belongs to a class of drugs called angiotensin II receptor blockers (ARBs). Losartan works by blocking the action of a hormone called angiotensin II, which can cause blood vessels to narrow and increase blood pressure. By blocking the effect of angiotensin II, losartan helps to relax blood vessels, lower blood pressure, and improve blood flow.
Apart from treating high blood pressure, losartan may also be prescribed for the management of certain conditions such as:
- Heart failure: Losartan can be used in patients with heart failure to improve heart function and reduce the risk of hospitalization.
- Diabetic nephropathy: It is also used to slow the progression of kidney disease in people with type 2 diabetes.
- Stroke prevention: In some cases, losartan may be prescribed to reduce the risk of stroke in patients with certain risk factors.
Losartan is usually taken orally in the form of tablets or suspension. It is available in various strengths, and the dosage prescribed will depend on the specific condition being treated and the individual's medical history. As with any medication, it is important to follow your healthcare provider's instructions and recommendations when taking losartan, as there may be potential side effects and interactions with other medications. If you have questions or concerns about losartan or any other medicine, it is best to consult with your health care professional.
