High blood pressure - Penbutolol

Hypertension - Penbutolol


Penbutolol is a drug that is used for the treatment of hypertension.

It is also used for cardiac arrhythmias and to generally reduce the workload on the heart. A trade name for Penbutolol is Betapressin.

Mode of action

Penbutolol belongs to the group of non-selective beta-blockers. Once absorbed into the body the substance is not only in the beta-1 receptor, but can also attach to other beta receptors

It blocks substances such as adrenaline or noradrenaline, but the beta blocker blocks their path, so they can not react in the autonomic nervous system. It reduces the risk of strokes and also relieves the pumping function of the heart.

Side effects of penbutolol

Penbutolol as beta-blockers brings help with hypertension

You may suffer from occasional dizziness, headaches, fatigue and excessive sweating. These symptoms usually occur independently of each other or sometimes all at once. Rarely, it can cause nightmares, blurred vision, respiratory constrictions or a lack of libido.

Very rarely, psoriasis and heart pain have been observed in some patients. Other side effects may sometimes occur. These side effects include depression, over-acidification of the blood, dry mouth, gastrointestinal discomfort and skin irritations, such as redness and swelling.

Interactions of penbutolol

If used together with a tricyclic antidepressant to be administered, a sharp reduction in blood pressure may occur.

Frequently fainting spells and a feeling of weakness can be the result. Additional interaction can lead to a drop in blood pressure that may be caused by a calcium antagonist of the nifedipine type.

The effect can also be increased if drugs for sugar diseases, such as insulin, are used simultaneously. Used in combination with cardiac glycosides, it may cause a decrease in the heart rate. If used with clonidine, there may be a rapid and strong increase in blood pressure, which causes hypertension and the agent becomes ineffective after the withdrawal of this drug.

In order to reduce high blood pressure again, clonidine must therefore be discontinued slowly. The cure for high blood pressure also reacts with ergot alkaloids, which can lead to circulatory disorders.
