Norvasc better for lowering blood pressure

DALLAS (Reuters) - Pfizer's Norvasc was more effective at
reducing blood pressure near the heart than standard, older
treatments known as beta blockers, according to a study
presented on Sunday at the American Heart Association
scientific meeting.

The results also indicate that blood pressure near the
heart, or central aortic blood pressure, may be a better
predictor of heart attack and stroke risk than a traditional
blood pressure measurement taken from the arm, researchers

"The Norvasc-based treatment was certainly better in
lowering central pressure than the atenolol-based conventional
recommended treatment," said lead researcher Bryan Williams, a
professor at the University of Leicester School of Medicine.

Norvasc belongs to a class of drugs known as calcium
channel blockers, while atenolol is a beta blocker.
