Losartan

Losartan is one of the most commonly prescribed medicines for blood pressure and heart conditions. It falls under the category of angiotensin II receptor blockers (ARBs). The key purpose of this medicine is to relax blood vessels, easing the heart's work by allowing it to pump blood efficiently. This blog covers everything about this medication—from uses and dosage to precautions and side effects. 

What is Losartan?

Losartan is a drug mainly used to treat high blood pressure. It is prescribed to lessen the risk of stroke in individuals with high blood pressure and left ventricular hypertrophy. In addition, losartan is suggested to slow long-term kidney damage in patients with type 2 diabetes who are also suffering from high blood pressure. It does this by blocking the action of a natural substance that causes blood vessels to tighten; this enables blood to flow more smoothly and the heart to pump more effectively.

How Do Losartan Tablets Work?

Losartan works by blocking a chemical in the body called angiotensin II. It normally causes blood vessels to tighten. When this action is blocked, blood vessels can relax and widen. This helps decrease blood pressure but has the added benefit of enabling the heart to pump blood more easily. 

Can I Take Losartan with Other Medicines?

When taking Losartan, it's crucial to inform your doctor about all the medications you're currently using, including prescription and over-the-counter drugs, as well as any vitamins or herbal supplements. Certain medications can interact with Losartan, potentially altering its effectiveness or increasing the risk of serious side effects. For instance, combining Losartan with drugs that raise potassium levels can lead to hyperkalemia. In some cases, your doctor may need to adjust your dosage or monitor you more closely, particularly if you're also taking diuretics, lithium, or nonsteroidal anti-inflammatory drugs.

Dosage Information

The dosage for Losartan depends on the stage of a patient's condition and individual response. In adults with hypertension, the recommended initial dose is 50 mg once a day. The dosage is increased to 100 mg a day, depending on the blood pressure response noted. For heart failure, the initial dose is usually 50 mg once a day, increased to 100 mg once a day. In patients with type 2 diabetes, for the prevention of nephropathy, the recommended dose is 50 mg once a day; it could be increased to 100 mg once a day, which should be individually decided based on the blood pressure response of the patient.
