Indications & Clinical Uses

Losartan, the active ingredient in Theosart-50, is primarily used to treat high blood pressure, also known as hypertension. It belongs to a class of drugs called angiotensin II receptor blockers, which help relax blood vessels to improve blood flow. This medication may also be prescribed to protect the kidneys from damage due to diabetes and to reduce the risk of stroke in patients with heart disease.

Side Effects

Theosart-50 works by blocking the action of a natural substance that tightens blood vessels, allowing them to stay open and relaxed. This helps lower blood pressure and improves circulation throughout the body. Patients may notice improved energy levels and reduced strain on the heart over time as the medication takes effect.

Precautions & Warnings

Keep Theosart-50 in its original packaging away from moisture and direct sunlight. Store at room temperature and ensure it is out of reach of children and pets. Avoid crushing or splitting tablets unless directed by a healthcare professional. If you miss a dose, take it as soon as you remember, but skip it if it is almost time for the next dose.

Avoid Interactions

Theosart-50 may interact with other medications that affect blood pressure, such as diuretics or potassium supplements, as well as nonsteroidal anti-inflammatory drugs (NSAIDs). Alcohol consumption may enhance the blood pressure-lowering effects, leading to dizziness or lightheadedness. Always inform your doctor about all medications and supplements you are taking.
