There are numerous classes of medications used to treat high blood pressure; they include diuretics, angiotensin-converting enzyme inhibitors (ACEIs), angiotensin receptor blockers (ARBs), calcium channel blockers (CCBs), beta-receptor
blockers, and alpha-receptor blockers.
Among specific topics are autonomic pharmacology and stress, beta-receptor
antagonists (beta-blockers), psychotherapeutic agents, analgesic and anti-inflammatory drugs, dietary supplements, and performance-enhancing substances.
Racepinephrine is an alpha- and beta-receptor
stimulant that works by widening the air passage and making it easier to breathe.
The new study unveiled an elegant intracellular signalling system in which beta-receptor
activation modulates alpha-adrenergic signaling.
Glucocorticoids enhance beta-receptor
stimulation by increasing the number and availability of beta receptors on the cell surfaces and by increasing affinity of the receptor for beta agonists.
, atheroma and cardiovascular damage.
3) Beta blockers prevent the flow of adrenalin to the beta-receptor
sites in the autonomic nervous system.
Although further investigation is required to examine the mechanism of action of propranolol in curing aphthous ulcers, our working hypothesis is that beta-receptor
inhibition may be crucial in alleviating one of the most important predisposing factors, namely stress," he said.
These agents are partial beta-receptor
agonists and, thus, do not affect resting heart rate, cardiac output, and peripheral blood flow.
In patients with obstructive lung disease and cardiac arrhythmia, bronchodilating agents such as beta-receptor
agonists or theophylline preparations have been reported to induce supraventricular tachyarrhythmias (23,24).
