Losartas 50mg tablets contain losartan, an antihypertensive medication primarily used for managing high blood pressure (hypertension) and protecting kidney function in certain patients. The packaging typically includes 30 tablets.
Key Uses
- Hypertension Management: Losartas is effective in lowering high blood pressure, which helps reduce the risk of stroke and heart attacks.
- Heart Protection: It is used to decrease the risk of stroke in patients with high blood pressure and left ventricular hypertrophy (enlargement of the heart).
- Diabetic Nephropathy: Helps protect the kidneys in patients with type 2 diabetes and hypertension.
Mechanism of Action
Losartan works by blocking the action of angiotensin II, a hormone that causes blood vessels to constrict. By inhibiting its effects, losartan helps relax blood vessels, allowing blood to flow more freely, which lowers blood pressure and reduces strain on the heart.
Dosage and Administration
- Recommended Dosage: The typical starting dose is 50 mg once daily, which may be adjusted based on individual response and blood pressure levels. For some patients, the dose may be increased to 100 mg once daily.
- Administration Instructions: Take losartan exactly as prescribed by your healthcare provider. It can be taken with or without food. Swallow the tablet whole with a glass of water; do not crush or chew.
Side Effects
Common side effects may include:
- Dizziness
- Fatigue
- Nausea
- Back pain
- Cold symptoms (e.g., stuffy nose)
Serious side effects can include:
- High potassium levels (hyperkalemia), leading to muscle weakness or irregular heartbeat.
- Kidney problems, such as reduced urine output or swelling.
- Allergic reactions (e.g., rash, swelling of the face or throat).
Precautions
- Contraindications: Not recommended for individuals with known allergies to losartan or those with severe liver or kidney disease.
