ß-adrenergic receptor blocker poisoning

Management of Beta-Adrenergic Blocker Poisoning

4 Beta-adrenergic blocking agents or β-blockers are prescribed for the treatment of a broad array of common disorders. Their widespread use, coupled with a narrow therapeutic index, contributes to their being a significant cause of poisoning from overdose and the second most common cause of mortality from cardiovascular agents. This article provides an overview of beta-adrenergic system pathoph...

ß-adrenergic receptor function and regulation in hypertension

Alterations in platelet o2-adrenoceptor and mononuclear leucocyte ß2-adreno-ceptor characteristics in primary hypertension have been studied quite exten-sively The results of these studies are not consistent, which may be due to therelatively small number of subjects in most of the studies. In the present study,the o2-adrenoceptor characteristics were compared between 65 hyperte...

Adrenergic hypersensitivity after beta-blocker withdrawal.

We investigated the possibility of a rebound increase in sympathetic response after stopping beta-blocker treatment by measuring heart rate under conditions of increased sympathetic drive, as provided by standing with vasodilatation, or the Valsalva manoeuvure. Significant rebound increases in heart rate were observed after stopping propranolol given for one or more weeks but not when given for...
