Atenolol
Unknown / Multiple | Atenolol (Medication)
Desc:
Atenolol is a beta-adrenergic blocking agent that blocks the effects of adrenergic drugs, for example, adrenaline or epinephrine, on nerves of the sympathetic nervous system. One of the important functions of beta-adrenergic stimulation is to stimulate the heart to beat more rapidly. By blocking the stimulation of these nerves, atenolol reduces the heart rate and is useful in treating abnormally rapid heart rhythms. Atenolol also reduces the force of contraction of heart muscle and lowers blood pressure. Unlike propranolol, atenolol does not pass through the blood–brain barrier thus avoiding various central nervous system side effects. ...
