Beta-blockers can also block the stimulation of the heart form electrical impulses-they can control irregular heartbeats-thus lowering the activity of the heart and slowing down the heart rate. Hypertension-beta-blockers lower blood pressure by slowing down the heart rate, as well as reducing the force of the heart. Blood still gets to all parts of the body, but at reduced pressure. Glaucoma-pressure within the eyeball is reduced with beta-blocker eye drops.
They block sympathetic stimulation of the heart and reduce systolic pressure, heart rate, cardiac contractility and output, so decrease myocardial oxygen demand and increase exercise tolerance. Beta adrenergic blocking agents are used to treat angina, control abnormal heart rhythms and to reduce high blood pressure. However, blocking of the beta receptors may cause bronchial constriction therefore care has to be taken with the use of beta blockers in patients with respiratory conditions.
