Beta blockers are busted – what happens next?

IT IS very rare for new evidence to question or even negate the utility of a well-established class of drugs. But after four decades as a standard therapy for heart disease and high blood pressure, it looks like this fate will befall beta blockers. Two major studies published within about a week of each other suggest that the drugs do not work for these conditions. This is a big surprise, with big implications.

The first beta blocker, Inderal, was launched in 1964 by Imperial Chemical Industries for treatment of angina. This drug has been hailed as one of great medical advances of the 20th century. Its inventor, James Black, was awarded the Nobel prize in medicine in 1988.

 Beta blockers are busted – what happens next?

They have treated heart disease for 40 years, but it now seems that beta blockers don’t work. What went wrong?

3 Reasons Why Beta Blockers Could Ultimately Hold You Back

For the record, I’m not necessarily against the use of beta-blockers. I just don’t think you need them. In fact, if your goal is to play your absolute best, beta-blockers will probably hold you back.


Beta-blockers, also known as beta-adrenoceptor blocking agents, are medications used to treat conditions such as angina, heart failure and high blood pressure.


You cannot take a beta-blocker if you have certain conditions, including: •Asthma. •Uncontrolled heart failure. •Very slow heart (bradycardia). •Low blood pressure (hypotension). •Certain problems with the rhythm of your heart - eg, sick sinus syndrome.

Metoprolol (Lopressor)

The usual initial dosage of metoprolol tartrate tablets is 100 mg daily in single or divided doses, whether used alone or added to a diuretic.

Propranolol (Inderal)

The usual initial dosage is 40 mg propranolol hydrochloride twice daily, whether used alone or added to a diuretic.
