The main effect of beta blockers is on the control of adrenalin which if not controlled by relaxation exercises etc will disrupt the control you need as a musician.It would not be good for a football player to take them as the adrenalin rush is needed.I hope that helps

"beta" beta-blocker

Miller-Keane Medical Dictionary, 2000

A drug that blocks the action of epinephrine at beta-adrenergic receptors on cells of effector organs. There are two types of these receptors: beta1-receptors in the myocardium and beta2-receptors in the bronchial and vascular smooth muscles.

The principal effects of beta-adrenergic stimulation are increased heart rate and contractility, vasodilation of the arterioles that supply the skeletal muscles, and relaxation of bronchial muscles.
Because of their effects on the heart, beta-blockers are used to treat angina pectoris, hypertension, and cardiac arrhythmias. And, because they decrease the workload of the heart, they are effective in reducing the long-term risk of mortality and reinfarction after recovery from the acute phase of a myocardial infarction. (heart attack) They are also used for the prophylaxis of migraine.


Nonselective beta-blockers affect both types of receptors and can produce bronchospasm in patients with asthma or chronic obstructive pulmonary disease. If such patients need a beta-blocker, they should be given a cardioselective beta-blocker that preferentially blocks the beta1-receptors in the heart.


Nonselective beta-blockers include propranolol (Inderal), used for treatment of angina, hypertension, arrhythmias, and migraine and for prophylaxis after the acute phase of a myocardial infarction; nadolol (Corgard), used for treatment of angina and hypertension; and timolol, used as an ophthalmic preparation (Timoptic) for treatment of glaucoma and as an oral preparation (Blocadren) for treatment of hypertension and for prophylaxis after the acute phase of a myocardial infarction. Cardioselective beta-blockers are used for treatment of hypertension and include atenolol (Tenormin) and metoprolol (Lopressor).

SULPHUR, Here is a link to the other topic on beta-blockers. I didn't notice it before. HERE. I see you've already found it.
