Beta blockers vary in their lipophilicity (fat solubility) and in turn in their ability to cross the blood–brain barrier and exert effects in the central nervous system. Beta blockers with greater blood–brain barrier permeability can have both neuropsychiatric therapeutic benefits and side effects, as well as adverse cognitive effects.
Common side effects include nausea, abdominal pain, and constipation. It may worsen the symptoms of asthma. Propranolol may cause harmful effects for the baby if taken during pregnancy. Its use during breastfeeding is probably safe. It is a non-selective beta blocker which works by blocking β-adrenergic receptors.
Nebivolol is a beta blocker used to treat high blood pressure and heart failure. As with other β-blockers, it is generally a less preferred treatment for high blood pressure. It may be used by itself or with other blood pressure medication. It is taken by mouth. Common side effects include dizziness, feeling tired, nausea, and headaches.
Atenolol. Atenolol is a beta blocker medication primarily used to treat high blood pressure and heart-associated chest pain. [3] Atenolol, however, does not seem to improve mortality in those with high blood pressure. [4] [5] Other uses include the prevention of migraines and treatment of certain irregular heart beats.
Bisoprolol. Bisoprolol, sold under the brand name Zebeta among others, is a beta blocker which is selective for the beta-1 receptor [7] and used for cardiovascular diseases, [7] including tachyarrhythmias, high blood pressure, angina, and heart failure. [7] [8] It is taken by mouth. [7]
Metoprolol is classified as a moderately lipophilic beta blocker. More lipophilic beta blockers tend to cross the blood–brain barrier more readily, with greater potential for effects in the central nervous system as well as associated neuropsychiatric side effects. Metoprolol binds mainly to human serum albumin with an unbound fraction of 0.88.
Adrenergic antagonist. Visual definition of an antagonist, where it compared to agonists and reverse agonists. An adrenergic antagonist is a drug that inhibits the function of adrenergic receptors. There are five adrenergic receptors, which are divided into two groups. The first group of receptors are the beta (β) adrenergic receptors.
Common side effects include dizziness, tiredness, joint pain, low blood pressure, nausea, and shortness of breath. Severe side effects may include bronchospasm. Safety during pregnancy or breastfeeding is unclear. Use is not recommended in those with liver problems. Carvedilol is a nonselective beta blocker and alpha-1 blocker.
Studies have found serious side effects to be more common in individuals also taking digoxin, possibly because of pre-existing heart failure in those people. As with other beta blockers, it may interact with calcium channel blockers, catecholamine-depleting drugs, insulin or antidiabetic drugs, β 2-adrenergic receptor agonists, and clonidine.
Celiprolol. Celiprolol is a medication in the class of beta blockers, used in the treatment of high blood pressure. It has a unique pharmacology: it is a selective β1 receptor antagonist, but a β2 receptor partial agonist. It is also a weak α2 receptor antagonist. It was patented in 1973 and approved for medical use in 1982.
