1. WHAT LOSARTAN TABLETS ARE AND WHAT THEY ARE USED FOR
Losartan belongs to a group of medicines known as angiotensin-II receptor antagonists. Angiotensin-II is a substance produced in the body which binds to receptors in blood vessels, causing them to tighten. This results in an increase in blood pressure. Losartan prevents the binding of angiotensin-II to these receptors, causing the blood vessels to relax which in turn lowers the blood pressure.
Losartan is used
• to treat patients with high blood pressure (hypertension) in adults and in children and adolescents 6-18 years of age.
• to treat patients with chronic heart failure when therapy with specific medicines called angiotensin-converting-enzyme inhibitors (ACE inhibitors, medicine used to lower high blood pressure) is not considered suitable by your doctor. If your heart failure has been stabilised with an ACE inhibitor you should not be switched to losartan.
• patients taking losartan should have a left ventricula ejection fraction <40% and should be stabilised under the treatment of the chronic heart failure.
