THURSDAY, April 29, 2004 (HealthDayNews) -- An investigational drug called Ranexa may offer relief to people with angina, a chronic condition that causes chest pain and limits physical activity, according to a new study.
It found the drug significantly increased the ability of angina patients to exercise. This study evaluated whether the drug was effective on its own and established the effective dosage amount.
The study appeared in a recent issue of the Journal of the American College of Cardiology.
A previous study found that when Ranexa was combined with current therapies to treat angina -- such as beta-blockers or calcium blockers -- it helped increase a patient's ability to exercise.
Ranexa is currently under review by the U.S. Food and Drug Administration.
The U.S. National Heart, Lung, and Blood Institute has more about angina.
