Olmesartan: Dosage, Uses, and Side Effects
Olmesartan is a medication primarily used to manage high blood pressure, or hypertension. It belongs to a class of drugs known as angiotensin II receptor antagonists (ARBs). By blocking the action of angiotensin II, a substance in the body that narrows blood vessels, Olmesartan helps to relax blood vessels, leading to lower blood pressure. This not only helps in lowering the risk of heart disease and stroke but also improves overall cardiovascular health.
Dosage
The typical starting dose of Olmesartan is 20 mg once daily. Depending on the individual’s response and blood pressure readings, the dose may be increased to a maximum of 40 mg per day. It’s crucial to take Olmesartan consistently at the same time each day, with or without food. If a dose is missed, it should be taken as soon as remembered but skipped if it’s close to the time for the next dose. Doubling up is not recommended.
