What Olmesartan is used for
Olmesartan belongs to a group of medicines called angiotensin-II receptor antagonists. They lower blood pressure by relaxing the blood vessels.
Olmesartan is used for the treatment of high blood pressure in adults and in children and adolescents aged 6 to less than 18 years. High blood pressure can damage blood vessels in organs such as the heart, kidneys, brain and eyes. In some cases, this may lead to a heart attack, heart or kidney failure, stroke or blindness. Usually high blood pressure has no symptoms.
