What works?

Learn more about the effects of these drugs. The most reliable research is summed up for you in our featured article.

Olmesartan is used alone or together with other medicines to treat high blood pressure (hypertension). High blood pressure adds to the workload of the heart and arteries. If it continues for a long time, the heart and arteries may not function properly. This can damage the blood vessels of the brain, heart, and kidneys, resulting in a stroke, heart failure, or kidney failure. Lowering blood… Read more

Evidence reviews

Antihypertensive effects of olmesartan compared with other angiotensin receptor blockers: a meta-analysis

This review found that olmesartan was associated with better antihypertensive efficacy than losartan and valsartan, for patients with hypertension. The adverse events with olmesartan were similar to those with the other angiotensin-receptor blockers. The review was generally well conducted, and the authors' conclusions are likely to be reliable.

Dementia: A NICE-SCIE Guideline on Supporting People With Dementia and Their Carers in Health and Social Care

This guideline has been developed to advise on supporting people with dementia and their carers in health and social care. The guideline recommendations have been developed by a multidisciplinary team of health and social care professionals, a person with dementia, carers and guideline methodologists after careful consideration of the best available evidence. It is intended that the guideline will be useful to practitioners and service commissioners in providing and planning high-quality care for those with dementia while also emphasising the importance of the experience of care for people with dementia and carers.

Drug Class Review: Direct Renin Inhibitors, Angiotensin Converting Enzyme Inhibitors, and Angiotensin II Receptor Blockers: Final Report [Internet]

The renin-angiotensin system is a complex biologic system between the heart, brain, blood vessels, and kidneys that leads to the production of biologically active agents, including angiotensin I and II and aldosterone, which act together to impact a variety of bodily functions including blood vessel tone, sodium balance, and glomerular filtration pressure. The multiple and varied effects of these agents allows the renin-angiotensin system to play a wide role in the pathology of hypertension, cardiovascular health, and renal function. Our ability to begin to intervene upon the complex cycle of hormone and other biochemical agent production within the renin-angiotensin system began with the advent of the first orally active ACE-I (angiotensin converting enzyme inhibitor), captopril, in 1981. AIIRAs (angiotensin II receptor blockers) were developed as an alternative to ACE-I, and block the interaction between angiotensin II and the angiotensin receptor. Losartan, the first commercially available AIIRA, was approved for clinical use in 1995. The goal of this report is to compare the effectiveness and harms between aliskiren and placebo and between AIIRAs and ACEIs in the treatment of diagnosed coronary heart disease, hypertension, left ventricular dysfunction, heart failure, nondiabetic chronic kidney disease, or diabetic nephropathy.

Choosing Medicines for High Blood Pressure: A Review of the Research on ACEIs, ARBs, and DRIs

You will learn what research says about three types of medicine for high blood pressure, how well they work, how they compare to each other, and their side effects. This information can help you talk with your doctor as you decide which ACEI, ARB, or DRI is best for you.

“ACE Inhibitors” and “ARBs” To Protect Your Heart? A Guide for Patients Being Treated for Stable Coronary Heart Disease

You have coronary heart disease, a disease affecting the arteries of your heart. You may have had a heart attack or suffer from chest pains with exercise, but your symptoms are not changing. Your coronary heart disease is in “stable” condition. This means that your symptoms have not changed or become worse. Your doctor recommends adding a medicine called an ACE Inhibitor or an ARB. You do not take medicine for high blood pressure (also called “hypertension”).
