Bisoprolol blocks the action of the sympathetic nervous system on the heart by blocking the heart’s β1-adrenergic receptors. Bisoprolol reduces the rate & force of contraction of the heart, thus lowers blood pressure.
The dose of Bisoprolol must be individualized to the needs of the patient. The usual starting dose is Bisoprolol 5 mg once daily. In some patients, Bisoprolol 2.5 mg may be an appropriate starting dose. If the antihypertensive effect of Bisoprolol 5 mg is inadequate, the dose may be increased to 10 mg and then, if necessary, to 20 mg once daily.
