Bromocriptine inhibits norepinephrine release

Clin Pharmacol Ther. 1979 Feb;25(2):137-42. doi: 10.1002/cpt1979252137.

Abstract

Bromocriptine is a dopamine agonist that induces postural hypotension and can be used as an antihypertensive. The drug inhibits release of norepinephrine (NE) from an isolated artery by stimulating presynaptic receptors. In normotensive subjects it lowers both plasma and cerebrospinal fluid (CSF) levels of NE by 50% and lowers blood pressure moderately in standing subjects and slightly in recumbent subjects. Through central and peripheral mechanisms, bromocriptine inhibits sympathetic nervous discharge of NE.
