Beta blockers, also spelled β-blockers, are a class of medications that are predominantly used to manage abnormal heart rhythms ( arrhythmia ), and to protect the heart from a second heart attack after a first heart attack ( secondary prevention ). [1]
β adrenergic receptor antagonists (also called beta-blockers or β-blockers) were initially developed in the 1960s, for the treatment of angina pectoris but are now also used for hypertension, congestive heart failure and certain arrhythmias. [1]
Propranolol, sold under the brand name Inderal among others, is a medication of the beta blocker class. It is used to treat high blood pressure, a number of types of irregular heart rate, thyrotoxicosis, capillary hemangiomas, performance anxiety, and essential tremors, as well to prevent migraine headaches, and to prevent further heart problems in those with angina or previous heart attacks.
Inderal (propranolol) – a beta blocker; it is used for acute anxiety, panic attacks, and hypertension; Intuniv - an extended release, non-stimulant alpha-2 adrenergic agonist used to treat attention deficit hyperactivity disorder. Available in instant-release under the brand-name Tenex.
Metoprolol is a beta blocker, or an antagonist of the β-adrenergic receptors. It is specifically a selective antagonist of the β 1-adrenergic receptor and has no intrinsic sympathomimetic activity. Metoprolol exerts its effects by blocking the action of certain neurotransmitters, specifically adrenaline and noradrenaline.
Beta 1 blocker. Myocardial infarction (heart attack) Since beta 1 receptor are mainly located in the heart, most beta 1 blockers take abnormalities associated with the heart as the target. [5] It treats medical conditions like hypertension, arrhythmias, heart failure, chest pain, myocardial infarction.
The cellphone-friendly website and "MYmta" app, currently in a beta test phase, show straphangers real-time subway, bus and commuter rail information that has been housed in separate apps.
Timolol is a non-selective beta blocker. Timolol was patented in 1968, and came into medical use in 1978. It is on the World Health Organization's List of Essential Medicines. Timolol is available as a generic medication.
The app is still in Beta testing, but will eventually succeed the MYmta app. The new app has schedules and service alerts for subways, buses, Long Island Rail Road and Metro-North Railroad all in ...
The beta-1 adrenergic receptor (β 1 adrenoceptor), also known as ADRB1, can refer to either the protein-encoding gene (gene ADRB1) or one of the four adrenergic receptors. [5] It is a G-protein coupled receptor associated with the Gs heterotrimeric G-protein that is expressed predominantly in cardiac tissue.
