sympatholytic

 [sim″pah-tho-lit´ik]
1. blocking transmission of impulses from the adrenergic (sympathetic) postganglionic fibers to effector organs or tissues, inhibiting such sympathetic functions as smooth muscle contraction and glandular secretion.
2. an agent that produces such an effect; called also antiadrenergic.

sym·pa·tho·lyt·ic

(sim'pă-thō-lit'ik),
Denoting antagonism to or inhibition of adrenergic nerve activity.
See also: adrenergic blocking agent, antiadrenergic.
[sympatho- + G. lysis, a loosening]

sympatholytic

/sym·pa·tho·lyt·ic/ (-lit´ik)
1. antiadrenergic; opposing the effects of impulses conveyed by adrenergic postganglionic fibers of the sympathetic nervous system.
2. an agent that so acts.

sympatholytic

(sĭm′pə-thō-lĭt′ĭk)
adj.
Opposing the physiological effects caused by stimulation of the sympathetic nervous system: a sympatholytic treatment.

sym·pa·tho·lyt·ic

(sim'pă-thō-lit'ik)
