Bisoprolol

Synonyms

Bisohexal, Rivacor, Bilol, Bisacardiol, beta blockers

General

Bisoprolol belongs to the group of beta-blockers.

Beta receptors, also known as beta adrenergic receptors, are found in different places in the body and are activated by the hormone adrenaline, which is released by the body when it is exerted, excited and tense. In particular, many of the beta receptors are located in the heart, which beats faster and stronger when adrenaline is released, so that the body can meet the demands that are placed on it. The cardiac output must be increased, i.e. the amount of blood that the heart pumps out per minute.
Blood pressure is also increased because muscle cells are also found in the blood vessels (arteries and veins) of the body. Blood pressure increases or decreases depending on how tense or relaxed you are.
However, blood pressure also depends on other factors, such as arteriosclerosis or how sporty you are. Other beta receptors are located in the lungs and muscles.

Beta blockers like bisoprolol make use of this mechanism and attack the beta receptors directly and block the receptor so that adrenaline can no longer bind to the receptor. The result is that the heart beats slower and is better supplied with oxygen. In addition, the muscle cells in the vessels relax and thus the blood pressure is lowered.

Typical areas of application of beta blockers such as bisoprolol are high blood pressure, heart failure (heart failure) and circulatory disorders of the coronary arteries (angina pectoris).

to form

The active substance Bisoprolol fumarate is under different trade names expelled: Bisohexal, Rivacor, Bilol, Bisacardiol and numerous others. There is also bisoprolol in combination with Hydrochlorothiazide, a thiazide diuretic, for increased blood pressure control (e.g. Bilol comp., Concor plus).

Again, the dosage of bisoprolol should be slowly reduced over a period of 7-10 days.

Unless otherwise prescribed, the dosage is:

• at high blood pressure 5mg once a day, with mild high blood pressure may also be sufficient 2.5mg. A dose increase if the effect is insufficient up to 10mg per day.
• in the coronary heart disease (CHD, angina pectoris) 5mg once a day with a possible dose increase up to 10mg.
• in the stable chronic heart failure 1.25mg-10mg. The dosage is increased gradually. In addition, in the standard therapy of chronic heart failure in addition ACE inhibitors, Diuretics and maybe Cardiac glycosides given.

When should Bisohexal® not be used?

Absolute contraindications

• chronic Heart failure, acute or decompensating

• low blood pressure (so-called hypotension; systolic blood pressure or upper value <90mmHg)

Relative contraindication

• chronic obstructive pulmonary disease how COPD (severe chronic obstructive pulmonary dysfunction) or bronchial asthma
