Atenolol is a beta blocker medication primarily used to treat high blood pressure and heart-associated chest pain. [7] Although used to treat high blood pressure, it does not seem to improve mortality in those with the condition. [8] [9] Other uses include the prevention of migraines and treatment of certain irregular heart beats.
Actions of atenolol include the reduction in myocardial contractility and heart rate, hence producing the effect of lowering blood pressure and cardiac output. [14] Side effects of atenolol include cold extremities and exacerbation of cardiac failure , hence this drug is not suitable for patients with heart failure. [ 14 ]
In pharmacology, the term mechanism of action (MOA) refers to the specific biochemical interaction through which a drug substance produces its pharmacological effect. [2] A mechanism of action usually includes mention of the specific molecular targets to which the drug binds, such as an enzyme or receptor . [ 3 ]
Adrenergic blocking agents are a class of drugs that exhibit its pharmacological action through inhibiting the action of the sympathetic nervous system [1] in the body. The sympathetic nervous system(SNS) is an autonomic nervous system that we cannot control by will.
Atenolol/chlorthalidone, also known as co-tenidone, is a combination medication used to treat high blood pressure. [2] [3] It is made up of atenolol, a beta-blocker and chlortalidone, a diuretic. [4] It is not recommended as an initial treatment but may be used in those who are taking atenolol and chlortalidone individually. [5] It is taken by ...
Studies of combined oral alpha- and beta-blockade using an alpha-blocker (e.g., doxazosin or terazosin) in combination with a nonlipophilic beta-blocker with more reliable bioavailability (e.g., betaxolol, bisoprolol, atenolol and others) have shown a larger antihypertensive effect.
The action of drugs on the human body (or any other organism's body) is called pharmacodynamics, and the body's response to drugs is called pharmacokinetics. The drugs that enter an individual tend to stimulate certain receptors, ion channels, act on enzymes or transport proteins. As a result, they cause the human body to react in a specific way.
Beta blockers inhibit these normal epinephrine- and norepinephrine-mediated sympathetic actions, [3] but have minimal effect on resting subjects. [citation needed] That is, they reduce the effect of excitement or physical exertion on heart rate and force of contraction, [68] and also tremor, [69] and breakdown of glycogen. Beta blockers can ...
