This medicine contains the active ingredients bisoprolol and hydrochlorothiazide. Bisoprolol belongs to the group of medicines known as beta-blockers. It works by blocking beta-adrenergic receptors in your heart and the heart is then beating evenly and more slowly. Bisoprolol is also used in treatment of high blood pressure and angina pectoris (chest pain). Hydrochlorothiazide belongs to a group of medicines called thiazide diuretics, also known as water tablets. These medicines cause the kidneys to produce more urine, and in that way they free your body from retaining the extra fluid. Byol H is prescribed for the treatment of high blood pressure (essential hypertension).
