Less-expensive diuretics found superior in treatment of hypertension

17.12.2002


A major clinical trial of blood pressure medications has concluded that an inexpensive diuretic (water pill) is more effective in treating high blood pressure and preventing cardiovascular disease than newer more expensive medications.

The Antihypertensive and Lipid-Lowering Treatment to Prevent Heart Attack Trial (ALLHAT), conducted from February 1994 though March 2002, compared the drugs for use in starting treatment for high blood pressure.

"The preferred drug is the diuretic for three reasons. It provides better control of hypertension; it reduces complications from hypertension--particularly heart failure-- more effectively; and it is 10 to 20 times less expensive than the other drugs used in the trial," said Curt Furberg, M.D., Ph.D., of Wake Forest University Baptist Medical Center, chairman of the study’s steering committee.



ALLHAT is the largest study ever to compare different types of hypertension drugs. It included more than 33,000 participants age 55 years or older at 623 clinical sites in North America. All the patients had hypertension and at least one other coronary heart disease risk factor. Approximately 50 percent of the participants were women and 35 percent were African-American.

"The bottom line is ALLHAT has shown that it matters which drug you use to control hypertension," said Furberg.

Participants were randomly assigned to receive the diuretic chlorthalidone, amlodipine (a calcium channel blocker sold under the name Norvasc) or lisinopril, (an angiotensin-converting enzyme (ACE) inhibitor sold under the names Prinivil and Zestril.)

In 2000, another drug used in the trial, doxazosin (an alpha-blocker sold under the name Cardura) was pulled from the trial because it was determined early in ALLHAT that it was not as effective as the less expensive diuretic medication.

The study does not recommend that patients stop taking their medication if they are using a drug other than a diuretic. However they are encouraged to speak with their physicians about adding or switching to a diuretic for their treatment.

ALLHAT’s findings indicate that most patients will need more than one drug to adequately control their blood pressure and one of the drugs should be a diuretic. The National Heart, Lung and Blood Institute, part of the National Institutes of Health, supported the study.

Im Focus: Virus multiplication in 3D

Vaccinia viruses serve as a vaccine against human smallpox and as the basis of new cancer therapies. Two studies now provide fascinating insights into their unusual propagation strategy at the atomic level.

For viruses to multiply, they usually need the support of the cells they infect. In many cases, only in their host’s nucleus can they find the machines,...

Im Focus: Cheers! Maxwell's electromagnetism extended to smaller scales

More than one hundred and fifty years have passed since the publication of James Clerk Maxwell's "A Dynamical Theory of the Electromagnetic Field" (1865). What would our lives be without this publication?

It is difficult to imagine, as this treatise revolutionized our fundamental understanding of electric fields, magnetic fields, and light. The twenty original...

Im Focus: Highly charged ion paves the way towards new physics

In a joint experimental and theoretical work performed at the Heidelberg Max Planck Institute for Nuclear Physics, an international team of physicists detected for the first time an orbital crossing in the highly charged ion Pr⁹⁺. Optical spectra were recorded employing an electron beam ion trap and analysed with the aid of atomic structure calculations. A proposed nHz-wide transition has been identified and its energy was determined with high precision. Theory predicts a very high sensitivity to new physics and extremely low susceptibility to external perturbations for this “clock line” making it a unique candidate for proposed precision studies.

Laser spectroscopy of neutral atoms and singly charged ions has reached astonishing precision by merit of a chain of technological advances during the past...

Im Focus: Ultrafast stimulated emission microscopy of single nanocrystals in Science

The ability to investigate the dynamics of single particle at the nano-scale and femtosecond level remained an unfathomed dream for years. It was not until the dawn of the 21st century that nanotechnology and femtoscience gradually merged together and the first ultrafast microscopy of individual quantum dots (QDs) and molecules was accomplished.

Ultrafast microscopy studies entirely rely on detecting nanoparticles or single molecules with luminescence techniques, which require efficient emitters to...

Im Focus: How to induce magnetism in graphene

Graphene, a two-dimensional structure made of carbon, is a material with excellent mechanical, electronic and optical properties. However, it did not seem suitable for magnetic applications. Together with international partners, Empa researchers have now succeeded in synthesizing a unique nanographene predicted in the 1970s, which conclusively demonstrates that carbon in very specific forms has magnetic properties that could permit future spintronic applications. The results have just been published in the renowned journal Nature Nanotechnology.

Depending on the shape and orientation of their edges, graphene nanostructures (also known as nanographenes) can have very different properties – for example,...
