About this active substance

Telmisartan is a medication used to treat high blood pressure (hypertension) and to reduce the risk of cardiovascular events, such as heart attacks or strokes, in high-risk patients. It belongs to the class of angiotensin II receptor blockers (ARBs), which work by relaxing blood vessels, making it easier for blood to flow and lowering blood pressure.

Telmisartan is taken orally, usually once daily, and can be used alone or in combination with other antihypertensive medications. It is well-tolerated by most patients, and its effects last for 24 hours, providing effective blood pressure control.

Common side effects include dizziness, fatigue, nausea, and, rarely, increased potassium levels in the blood (hyperkalemia). It is contraindicated during pregnancy, as it may harm fetal development, and should be used with caution in patients with severe kidney impairment.
