Mechanism of Action
Losartan is a type of medication known as an angiotensin II receptor antagonist. Angiotensin II is a hormone that causes blood vessels to constrict, leading to increased blood pressure. Losartan works by blocking the effects of angiotensin II, which helps to relax and widen blood vessels, reducing blood pressure.
By blocking the action of angiotensin II, Losartan helps to lower blood pressure and improve blood flow, which can help to reduce the risk of heart attacks, strokes, and kidney problems in patients with high blood pressure or other cardiovascular conditions.
It is important to take Losartan exactly as prescribed by your healthcare provider to ensure optimal benefits and minimize the risk of side effects.
Mechanism of Action
Losartan is an angiotensin II receptor blocker (ARB) that works by blocking the action of angiotensin II, a hormone that causes blood vessels to constrict. By blocking angiotensin II, losartan helps to relax blood vessels, lower blood pressure, and improve blood flow throughout the body.
Additionally, losartan prevents the release of aldosterone, a hormone that can cause sodium and water retention, leading to increased blood volume and pressure. By inhibiting aldosterone, losartan helps to reduce the workload on the heart and improve heart function.
Overall, the mechanism of action of losartan helps to lower blood pressure, protect the heart, and improve overall cardiovascular health in individuals with hypertension and other cardiovascular conditions.

Dosage and Administration
Dosage: The recommended starting dose of losartan for adults is 50 mg once daily. In patients with conditions such as high blood pressure or diabetic nephropathy, the dosage may be increased to 100 mg once daily.
Administration: Losartan should be taken by mouth with a full glass of water. It can be taken with or without food. It is important to take the medication at the same time each day to maintain consistent levels in the body.
Missed Dose: If a dose of losartan is missed, it should be taken as soon as remembered. However, if it is close to the time of the next scheduled dose, the missed dose should be skipped and the regular dosing schedule resumed. It is not recommended to double up on doses to make up for a missed dose.
Special Populations: Dosage adjustments may be necessary for patients with hepatic impairment or renal impairment. Close monitoring and dose adjustments may be required in these populations.
Interactions with Other Drugs
It is essential to be aware of potential drug interactions when taking losartan to avoid any unwanted effects. Some medications may interact with losartan and alter its effectiveness or increase the risk of side effects. It is crucial to inform your healthcare provider about all the medications, supplements, and vitamins you are currently taking to prevent these interactions.
Common drugs that may interact with losartan include:
- Diuretics (water pills) – When taken with losartan, diuretics may increase the risk of low blood pressure.
- NSAIDs (non-steroidal anti-inflammatory drugs) – NSAIDs can decrease the effectiveness of losartan and increase the risk of kidney damage.
- Potassium supplements or salt substitutes containing potassium – Combining these with losartan can lead to increased potassium levels in the blood, which can be dangerous.
- Other blood pressure medications – Taking other blood pressure medications with losartan may cause a significant drop in blood pressure, leading to dizziness or lightheadedness.
Always consult your healthcare provider before starting or stopping any medications while taking losartan to avoid potential interactions and ensure safe and effective treatment.
