sympatholytic การใช้

• ?-blockers are sympatholytic drugs.
• Alpha 2 receptors are associated with sympatholytic properties . ? Adrenergic agonists have the opposite function of alpha blockers.
• Beta blockers, in addition to their sympatholytic ?1 activity in the heart, influence the renin angiotensin system at the kidneys.
• Sympathomimetic drugs mimic or enhance at least some of the effects of norepinephrine released by the sympathetic nervous system; sympatholytic drugs, in contrast, block at least some of the effects.
• Side-effects include combined sympatholytic ( e . g ., orthostatic hypotension and sexual dysfunction ) and parasympatholytic ( e . g ., constipation, urinary retention, glaucoma, blurry vision, decreased lacrimal gland secretion, dry mouth ( xerostomia ) ) effects.
