Blood Pressure Drugs at Bedtime May Cut Heart Risk

Study Suggests Benefits to Taking Blood Pressure Drugs Before Going to Sleep

Why Blood Pressure Drugs Work Best at Bedtime

Hermida tells WebMD that some of the body's blood pressure control systems are most active while we sleep. So medicines designed to control those systems work better when taken close to the time when the systems are activated most fully.

The study results ''make absolute sense to me," says Robert Graham, MD, MPH, an internist and director of residency research at Lenox Hill Hospital. Graham, an assistant professor of medicine at New York University, reviewed the study findings for WebMD.

''Certain medications have the greatest effect on the body while we sleep," he says. Indeed, bedtime dosing of blood pressure medications recently has been a hot topic among experts.

Graham has been prescribing blood pressure medicines to be taken at bedtime for years, he says, as it seems to help with the top side effects of blood pressure medicine: fatigue and drowsiness.

"If you do have high blood pressure, and have a hard time getting it [down to your] goal, maybe you should talk with your doctor about changing the time [you take the medicine]," he says.
