What is Sectral and how does it work?
Sectral« (acebutolol) belongs to a class of drugs known as beta blockers. As a beta blocker, Sectral« often works quickly, by relaxing blood vessels and slowing heart rate to improve blood flow and decrease blood pressure within hours.
Only people with certain health problems should take Sectral« (acebutolol) under the continuous supervision of their doctor. Conditions that affect a person's ability to safely take Sectral« include: bradycardia, asthma, heart block, heart failure and vascular disease.
How does Sectral treat hypertension (high blood pressure)?
Sectral« (acebutolol) works by relaxing blood vessels and slowing the heart rate to improve blood flow and decrease blood pressure.
How does Sectral treat ventricular arrhythmia and angina (chest pain)?
Sectral« (acebutolol) blocks the hormones norepinephrine and epinephrine (also known as adrenaline) from reaching beta-1 receptors in the heart and kidneys. Because these hormones increase heart rate, blocking them decreases heart rate and allows the heart to beat more regularly and require less oxygen, thereby improving ventricular arrhythmia and reducing angina (chest pain).
Before you begin taking Sectral« (acebutolol), make sure that your doctor has thoroughly evaluated your health.
