Full Consumer Medicine Information (CMI)
This leaflet provides important information about using NOTEN. You should also speak to your doctor or pharmacist if you would like further information
or if you have any concerns or questions about using NOTEN.
Where to find information in this leaflet:
1. Why am I taking NOTEN?
NOTEN contains the active ingredient atenolol. NOTEN is belongs to a group of medicines called beta-blockers.
It works by affecting the body's response to certain nerve impulses, especially in
the heart. As a result, it decreases the heart's need for blood and oxygen and therefore
reduces the amount of work the heart has to do. It widens the blood vessels in the
body, causing blood pressure to fall. It also helps the heart to beat more regularly.
NOTEN is used to:
lower high blood pressure, which is called hypertension
prevent angina
treat irregular heart rhythm or beat called arrhythmias
treat heart attacks, or reduce your risk of heart complications following a heart
attack
