GENERIC NAME: betaxolol

BRAND NAME: Kerlone (Discontinued Brand)

DRUG CLASS AND MECHANISM: Betaxolol is a beta-adrenergic blocking drug. The nerves of the sympathetic nervous system--a subdivision of the autonomic nervous system--release a chemical related to adrenaline that binds to the heart-rate controlling cells in the heart as well as the muscles of the heart. Binding causes the heart to beat faster and the muscles of the heart to contract more vigorously and work harder. Betaxolol blocks the binding of the adrenaline-like chemical and prevents the increases in heart rate and muscular contraction. As a result, blood pressure is lowered. By reducing the heart rate and muscular contraction, betaxolol also reduces the heart's need for oxygen to generate energy. Since angina pectoris (heart pain) occurs when the heart's need for oxygen is too great and exceeds the supply of oxygen, betaxolol can prevent angina pectoris. Betaxolol was approved by the FDA in 1985.
