Here, brothers, the main thing is not to confuse. Beta blockers prevent adrenaline from pumping our hearts. Due to this, the heart beats weaker and less frequently, and the pressure decreases.
But there are also beta-stimulants like Salbutamol, which dilate the bronchi and... spur the heart. Therefore, asthma medications often cause palpitations.
And vice versa. Beta blockers that have been prescribed for the heart can provoke bronchospasm and asthma attacks.
Sometimes even beta-blocker eye drops for glaucoma can cause bronchospasm.
Many people think that modern selective beta-blockers like bisoprolol do not work for asthma. In general, beta-blockers are called selective, which block the receptors for adrenaline in the heart, but do not climb into other organs. So it turned out that such selective drugs are safer, but they can still harm. If a person has severe asthma and their lungs are not functioning well, then even a selective beta-blocker can suffocate the asthmatic.
It is also important to understand that the detrimental effect of beta-blockers on the bronchi is not fully understood. There are some different mechanisms involved and not necessarily the receptors for adrenaline.
Remember how adrenaline works on the bronchi? Hit or run! It expands the bronchi so that you can escape from danger, greedily gasping for the incoming air stream.
In short, tell the pulmonologist about the pressure, and the cardiologist about the asthma.
