Labetalol may be utilized in the treatment of hypertension in conjunction with or independently of other drugs (hypertension). Strokes, heart attacks, and kidney problems can all be avoided by treating high blood pressure and lowering it. This medicine works by inhibiting both alpha and beta waves in the nervous system. It accomplishes this by inhibiting the effect that certain naturally occurring substances, including epinephrine, have on the cardiovascular system, specifically the heart. This effect reduces the strain placed on the heart, as well as the heart rate and blood pressure.
