Once the drugs were in clinical use, it was found they could lower the blood pressure in those who were suffering from hypertension or high blood pressure.

This lowering of pressure usually does not occur in those individuals whose blood pressure is normal. When used in high blood pressure, it can reduce the level to normal, yet, in bigger doses, does not drop it too low.

Beta blockers are particularly useful in sexually active men with raised blood pressure because they do not inferfere with male sexual function as do some of the other drugs.

Beta blockers are not themselves free from side-effects. They do not work in all cases of high blood pressure but neither do all other drugs. A major side-effect that limits the use of these drugs is their action on the lungs.

In asthma, there is constriction of muscle in the walls of the bronchial tubes. This bronchospasm causes the wheeze and the difficult breathing. Adrenalin and related chemicals can reverse this spasm and overcome the problem.
