A drug which stops the sympathetic nervous system working.
A drug that opposes the effects of the sympathetic nervous system. Drugs such as ‘guanethidine and methyldopa block the transmission of impulses along adrenergic nerves; they are used to treat high blood pressure. Drugs such as phentolamine and phenoxybenzamine block alpha-adrenergic receptors, causing, in particular, dilation of peripheral blood vessels; they are used for disorders of the circulation or to lower the blood pressure. Other sympatholytic drugs are beta blockers, which selectively block the beta-adrenergic receptors and principally affect the heart.
Drugs that inhibit or antagonize function within the sympathetic nervous system.
Interfering with, opposing, inhibiting, or destroying impulses from the sympathetic nervous system.
