10 Oct 2014 Abstract. Direct vasodilators and sympatholytic agents were some of the first antihypertensive medications discovered and utilized in the past century. However, side effect profiles and the advent of newer antihypertensive drug classes have reduced the use of these agents in recent decades. Outcome data
the postganglionic functioning of the sympathetic nervous system. They can block at 3 different levels : Peripheral sympatholytic drugs block the action of NA at the effector organ (heart or blood vessel). Ganglionic blockers that block impulse transmission at the sympathetic ganglia. Centrally acting sympatholytic
SUMMARY Antihypertensive drugs with pharmacological action due to sympatholytic activity have been second only to diuretics in their use and efficacy in normalizing blood pressure. Their pharmaco- logical actions have resulted in the notable absence of chemical toxicity, but because of symptomatic side effects, their use
pressure (BP)–lowering effect of methyldopa. Subse- quently, other direct-acting central sympatholytic drugs such as guanfacine and guanabenz were approved for treatment of hypertension in the United States. Moxo- nidine and rilmenidine are also centrally acting drugs used in England and other European countries but
The Effect of "Sympatholytic Drugs on the. Cardiovascular Responses to Epinephrine and Norepinephrine in Man. By EDWARD D. FREIS, M.D., J. CALVIN MACKAY, M.D., AND WILLIAM F. OLIVER, M.D.. Under controlled conditions the effects of various "sympatholytic" agents on the cardiovascular responses to
In recent years our understanding of molecular mechanisms of drug action and interindividual variability in drug response has grown enormously. Meanwhile, the practice of anesthesiology has expanded to the preoperative environment and numerous locations outside the OR. Anesthetic Pharmacology: Basic Principles

A sympatholytic (or sympathoplegic) drug is a medication that opposes the downstream effects of postganglionic nerve firing in effector organs innervated by the sympathetic nervous system (SNS). They are indicated for various functions; for example, they may be used as antihypertensives. They are also used to treat
