Atenolol is a

blood pressure medications.[6]

Common

feeling tired, heart failure, dizziness, depression, and shortness of breath.[3] Other serious side effects include bronchial spasm.[3] Use is not recommended during pregnancy[3] and alternative drugs are preferred when breastfeeding.[7] It works by blocking β1-adrenergic receptors in the heart, thus decreasing the heart rate and workload.[3]

Atenolol was patented in 1969 and approved for medical use in 1975.

generic medication.[3] In 2021, it was the 47th most commonly prescribed medication in the United States, with more than 14 million prescriptions.[10][11]

Medical uses

Atenolol is used for a number of conditions including

The role for β-blockers in general in hypertension was downgraded in June 2006 in the United Kingdom, and later in the United States, as they are less appropriate than other agents such as

angiotensin receptor blockers, particularly in the elderly.[14][15][16]

Side effects

Hypertension treated with a β-blocker such as atenolol, alone or in conjunction with a thiazide diuretic, is associated with a higher incidence of new onset type 2 diabetes mellitus compared to those treated with an ACE inhibitor or angiotensin receptor blocker. [17][18]

β-blockers, of which atenolol is mainly studied, provides weaker protection against stroke and mortality in patients over 60 years old compared to other antihypertensive medications.[19][20][21][14] Diuretics may be associated with better cardiovascular and cerebrovascular outcomes than β-blockers in the elderly.[22]

Overdose

Symptoms of

hexoprenalin or salbutamol will terminate bronchospasms. Blood or plasma atenolol concentrations may be measured to confirm a diagnosis of poisoning in hospitalized patients or to assist in a medicolegal death investigation. Plasma levels are usually less than 3 mg/L during therapeutic administration, but can range from 3–30 mg/L in overdose victims.[23][24]

Pharmacology

Pharmacodynamics

Atenolol is a

intrinsic sympathomimetic activity (i.e., partial agonist activity) or membrane-stabilizing activity.[25][2] However, the preferential action atenolol is not absolute, and at high doses it can also block β2-adrenergic receptors.[2]

Beta-blocking effects of atenolol include reduction in

duration of action of atenolol is dose-related and is correlated with circulating levels of atenolol.[2]

Pharmacokinetics

The

pharmacokinetic profile of atenolol results in it having relatively consistent plasma drug levels with about 4-fold variation between individuals.[2]

The

neuropsychiatric side effects.[25]

Atenolol undergoes little to no metabolism by the liver.[2] This is in contrast to other beta blockers like propranolol and metoprolol, but is similar to nadolol.[2] Instead of hepatic metabolism, atenolol is eliminated mainly via renal excretion.[2] Atenolol is excreted 50% in urine with oral administration and more than 85% in urine with intravenous administration.[2]

The

renal impairment, with the elimination rate being closely related to the glomerular filtration rate and with significant accumulation occurring when the creatinine clearance rate is under 35 mL/min/1.73 m2.[2]

Society and culture

Atenolol has been given as an example of how slow healthcare providers are to change their prescribing practices in the face of

patient compliance factor, such as treatment cost and duration, also affect adherence and popularity of therapy.[27]

    . Further research should be of high quality and should explore whether there are differences between different subtypes of beta-blockers or whether beta-blockers have differential effects on younger and older people [...] Beta-blockers were not as good at preventing the number of deaths, strokes, and heart attacks as other classes of medicines such as diuretics, calcium-channel blockers, and renin-angiotensin system inhibitors. Most of these findings come from one type of beta-blocker called atenolol. However, beta-blockers are a diverse group of medicines with different properties, and we need more well-conducted research in this area." (p. 2-3)
