Metoprolol, sold under the brand name Lopressor among others, is a medication used to treat angina, high blood pressure and a number of conditions involving an abnormally fast heart rate. [4] It is also used to prevent further heart problems after myocardial infarction and to prevent headaches in those with migraines . [ 4 ]
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.
Note that drugs may be cardioselective, or act on β 1 receptors in the heart only, but still have intrinsic sympathomimetic activity. Acebutolol (has intrinsic sympathomimetic activity, ISA) [80] Atenolol [80] Betaxolol [80] Bisoprolol [80] Celiprolol (has intrinsic sympathomimetic activity) [84] Metoprolol [80] Nebivolol [80] Esmolol [85]
The progress in β-blocker development led to the introduction of drugs with variety of properties. β-blockers were developed having a relative selectivity for cardiac β1-receptors (for example metoprolol and atenolol), partial adrenergic agonist activity , concomitant α-adrenergic blocking activity (for example labetalol and carvedilol) and ...
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. There are β 1, β 2, and β 3 receptors. The second group contains the alpha (α) adrenoreceptors.
The choice between the drugs is to a large degree determined by the characteristics of the patient being prescribed for, the drugs' side effects, and cost. Most drugs have other uses; sometimes the presence of other symptoms can warrant the use of one particular antihypertensive. Examples include: Age can affect the choice of medications.
It presents the drugs on two axes, instead of one, and is presented in tabular form. On the Y axis, each drug is listed, in roughly the Singh-Vaughan Williams order. On the X axis, the channels, receptors, pumps, and clinical effects are listed for each drug, with the results listed in a grid.
An antianginal is a drug used in the treatment of angina pectoris, a symptom of ischaemic heart disease. Myocardial ischemia arises from the dysfunction of coronary macrovascular or microvascular components, leading to a compromised supply of oxygen and nutrients to the myocardium. The underlying pathophysiological mechanisms encompass a range ...
