The adrenergic or sympathetic nervous system is part of the autonomic nervous system and comprises neural and endocrine circuits that use norepinephrine or epinephrine as neurotransmitters. The adrenergic system includes norepinephrine- and epinephrine-producing neurons in the central nervous system, norepinephrine-producing postganglionic sympathetic ...

Medical Clinics of North America, 1987
Although most of the centrally and peripherally-acting adrenergic inhibitors have been available for several years, they continue to contribute importantly to antihypertensive therapy. There are remarkably few contraindications to their use. They are useful in hypertension of all grades of severity, and are also valuable in complicated forms of ...

New England Journal of Medicine, 1995
Of the three classes of bronchodilators (β2-adrenergic–receptor agonists, methylxanthines, and anticholinergic agents), the β2-adrenergic–receptor agonists produce the greatest bronchodilation in patients with bronchial asthma.1 β2-Adrenergic agonists are generally preferred both for the relief of acute symptoms2,3 and for the prevention of exercise ...

Beta adrenergic agonists are the most widely used agents in the management of bronchospasm as a result of their rapid onset of action and predictable efficacy. Administration of these agents by inhalation provides several advantages, including rapid effect, decreased adverse effects, and fewer drug interactions.

Medicine & Science in Sports & Exercise, 1996
The gravity-dependency and age-dependency of noradrenergic vasoconstrictor outflow to skeletal muscle (muscle sympathetic nerve activity; MSNA) in humans was analyzed by applying microneurography technique. The basal level of MSNA in the horizontally supine position increased with aging without significant changes in arterial baroreflex sensitivity ...

Adrenergic Transmitter Release
Journal of Vascular Research, 1984Presynaptic release-modulating receptors on sympathetic nerve fibres have been found not only in a great number of animal tissues but also in various human blood vessels. Although basically the same types of receptors are present in animals and man (e.g., inhibitory muscarinic receptors and α<sub>2</sub>-adrenoceptors; facilitatory β ...
