Propranolol (INN) is a non-selective beta
blocker mainly used in the treatment of hypertension. It was the
first successful beta blocker developed. It is the only drug
proven effective for the prophylaxis of migraines in children.
Corlar - LA ® is a beta blocker used to treat high blood
pressure, irregular heartbeats, shaking (tremors), and other
conditions. It is used after a heart attack to improve the chance
of survival. It is also used to prevent migraine headaches and
chest pain (angina). Lowering high blood pressure helps prevent
strokes, heart attacks, and kidney problems. Preventing chest pain
can help improve your ability to exercise.
This drug works by blocking the action of certain natural
chemicals in your body (such as epinephrine) that affect the heart
and blood vessels. This effect reduces heart rate, blood pressure,
and strain on the heart.
