Video answer: Beta-adrenoceptor blocking drugs
Top best answers to the question «Beta adrenoceptor blocking drugs»
Beta blockers, also known as beta-adrenergic blocking agents, are medications that reduce your blood pressure. Beta blockers work by blocking the effects of the hormone epinephrine, also known as adrenaline. Beta blockers cause your heart to beat more slowly and with less force, which lowers blood pressure.

Beta adrenoceptor blocking drugs are relatively well tolerated and adverse reactions to them are not common. The ones that do occur are reviewed in this paper under the following headings: Short term adverse reactions, drug interactions, long term adverse reactions, risks in pregnancy and hazards of abrupt withdrawal.
Carvedilol is indicated for the treatment of mild, moderate or severe heart failure of ischemic or cardiomyopathic origin, in conjunction with digitalis, diuretics and ACE inhibitor, to reduce the progression ...
Beta-adrenergic blocking agents are commonly referred to as beta-blockers. Beta-blockers can be grouped into those that are non-selective (block both beta-1 and beta-2 receptors, such as nadolol, penbutolol, pindolol, propranolol, sotalol, and timolol), and those that are cardioselective (only block beta-1 receptors, and include acebutolol, betaxolol, bisoprolol, esmolol, and metoprolol).
Adverse reactions and interactions with beta-adrenoceptor blocking drugs. beta-Blocking drugs are widely used throughout the world and serious adverse reactions are relatively uncommon. Most of those which do occur are pharmacologically predictable and may be avoided by ensuring that patients who are to be given beta-blockers do not have a ...
Beta-adrenoceptor-blocking drugs and blood sugar control in diabetes mellitus. Wright AD, Barber SG, Kendall MJ, Poole PH. The effects on diabetic control of the relative cardioselective beta-blocker metoprolol and the non-selective drug propranolol were compared in 20 hypertensive diabetic patients receiving diet alone or diet and oral hypoglycaemic agents.
Beta-blockers are drugs that bind to beta-adrenoceptors and thereby block the binding of norepinephrine and epinephrine to these receptors. This inhibits normal sympathetic effects that act through these receptors. Therefore, beta-blockers are sympatholytic drugs.
Other properties : Some beta-blockers also block effects mediated at peripheral alpha-adrenoceptors (e.g. carvedilol and labetalol), stimulate beta2-adrenoceptors (e.g. celiprolol) or have direct vasodilator activity (e.g. nebivolol).
What are beta blockers and how do they work? Beta blockers, also known as beta-adrenergic blocking agents, are a class of drugs that works by blocking the neurotransmitters norepinephrine and epinephrine from binding to receptors. There are three known types of beta receptors, known as beta 1 (β 1), beta 2 (β 2) and beta 3 (β 3).
