Adrenergic beta-receptor blockade in hyperthyroidism.

Pharmacodynamic Effects of Beta-adrenergic Receptor Blockade in Patients with Hyperthyroidism.

Effect of beta-adrenergic blockade on plasma dopamine-beta-hydroxylase activity and triiodothyronine in hyperthyroidism.

The effect of propranolol on plasma dopamine-beta-hydroxylase activity and triiodothyronine was investigated in twelve subjects with Graves' disease. Plasma DBH activity, serum triiodothyronine and thyroxine were determined beforehand and electrocardiograms were recorded on the same days as the blood samples were taken. Propranolol administration was associated with clinical amelioration in blo...

Effect of chronic beta-adrenergic receptor blockade in congestive cardiomyopathy.

Adrenergic beta-blocking agents were given to 7 patients with advanced congestive cardiomyopathy who had tachycardia at rest (98 plus or minus 13 beats/min). The patients were on beta-adrenergic receptor blockade for 2 to 12 months (average 5-4 months). One patient was given alprenolol 50 mg twice daily and the other patients were given practolol 50 to 400 mg twice daily. Virus infection had oc...

Esmolol and beta-adrenergic blockade.

Tachycardia often presents difficult management problems in anesthesia. Because it increases myocardial oxygen demand so sharply, tachycardia can quickly place patients at risk of myocardial ischemia. It can occur for any number of reasons. Deepening the anesthetic, either with inhalation agent or opioids, will ablate increases in heart rate, but changes in heart rate are often transient and ch...
