What Are The Beta Blockers And Which Are The Main Beta Blockers Side Effects

What Are Beta Blockers

Beta Blockers Side EffectsThe beta blockers are a class of drugs which have as main effect the blockage of epinephrine (also known as adrenaline) and norepinephrine (also known as noradrenaline). Due to their effect, beta blockers are used to treat especially various conditions of the heart and circulatory system (i.e. atrial fibrillation, congestive heart failure, cardiac arrhythmias, angina pectoris, acute aortic dissection, Marfan syndrome, myocardial infarction, postural orthostatic tachycardia syndrome). Under the effect of a drug from the beta blockers class, heart beast more slowly, and there’s a decrease of the blood pressure, that’s why these drugs are also used for hypertension.

Beta blockers are also used for the treatment of glaucoma, migraine prevention, hyperthyroidism, anxiety disorders. Since they reduce essential tremor, they can be used to improve performance in certain activities that require finesse, for example shooting or archery sports.

Some of the most commonly used beta blockers are: nadolol, acebutolol, atenolol, bisoprolol, nebivolol, propanolol, pindolol, penbutolol, betaxolol, metoprolol.

Beta blockers side effects of mild nature can be: nausea, dyspnea (shortness of breath), dizziness, diarrhea, cold hands and feet, fatigue and drowsiness. Hair loss is also one of the side effects associated with the intake of beta blockers. Some of the beta blockers can also cause insomnia, nightmares, hallucinations and vivid dreams, that’s why they aren’t recommended to people with sleep disorders.
Needless to say, due to this class of drugs’ impact on the activity of the heart and blood flow, certain heart conditions and complications may occur.

Some of the beta blockers side effects that interest the heart and blood pressure are: heart blockage, heart failure, bradycardia (drop of the heart rate to under 50 beats/min. which may lead to cardiac arrest), hypotension or orthostatic hypotension (head rush, drop of blood pressure when a person stretches or stands up).

Beta blockers diminish the secretion of the aqueous humour, resulting in less of an intraocular pressure. Due to this effect, beta blockers are used for the treatment and management of glaucoma. However, in patients without this eye disease may experience abnormal vision as one of the beta blockers side effects. Also, some of the beta blockers are associated with edema as a side effect, one of the beta blockers that commonly causes this side effect is carvedilol.

One of the beta blockers side effects can be the alteration of the lipid or glucose metabolism. Especially beta blockers used for hypertension expose the patient to a higher risk of developing diabetes. That’s why in the United Kingdom, beta blockers are not recommended as first-line treatment for hypertension. Also, certain beta blockers may cause hyponatremia (low levels of sodium) and hyperkalemia (high levels of potassium).

Lastly, among the beta blockers side effects can be erectile dysfunction or sexual dysfunction.
