Alpha- and beta-adrenoceptor antagonists.
Antagonists acting on the betaor alphaadrenoceptors are used widely in medicine and in anaesthesia. The major indications for betaadrenoceptor blockade are coronary artery disease and arterial hypertension, while those for alphaadrenoceptor blockade include arterial hypertension, paroxysmal hypertension and chronic cardiac failure. The adrenoceptor antagonists interfere with important regulator...
متن کاملTEACHERS’ TOPICS Antianginal Actions of Beta-Adrenoceptor Antagonists
Angina pectoris is usually the first clinical sign of underlying myocardial ischemia, which results from an imbalance between oxygen supply and oxygen demand in the heart. This report describes the pharmacology of b-adrenoceptor antagonists as it relates to the treatment of angina. The b-adrenoceptor antagonists are widely used in long-term maintenance therapy to prevent acute ischemic episodes...
متن کاملAdrenoceptor Antagonists
Drugs that produce responses by interacting with adrenoceptors are referred to as adrenoceptor agonists or adrenergic agonists. Norepinephrine and isoproterenol are examples of such compounds. Agents that inhibit responses mediated by adrenoceptor activation are known as adrenoceptor antagonists, adrenergic antagonists, or adrenergic blocking agents. Prazosin and propranolol are examples of rec...
متن کاملHaemoperfusion with R-004 Amberlite resin for treating acute poisoning.
Eleven patients who had taken overdoses of barbiturates, glutethimide, tricyclic antidepressants, and chloroquine were treated by resin haemoperfusion using an R-004 haemoperfusion cartridge containing XAD-4 resin. All but one patient showed rapid clinical recovery and the drugs were cleared rapidly from the plasma. There were few complications. Resin haemoperfusion is more effective than dialy...
متن کاملBeta-adrenoceptor-mediated responsiveness of human internal mammary artery
The internal mammary artery (IMA) is currently the preferred conduit for myocardial revascularization. However, pre-operative vasospasm and a hypoperfusion state during maximal exercise may limit its use as a bypass graft. The mechanism of spasm has not been clearly defined. Since β-adrenoceptor activation plays a major role in vasorelaxation, the present study was carried out to investigate th...
