Also known as 3,4-Dihydroxyphenethylamine, 3-Hydroxytyramine, Deoxyepinephrine, Dopamin, Dopamina, Dopamine Hydrochloride, Dopaminergic, Dopaminum, Dophamine, Hydroxytyramin, Hydroxytyramine, Oxytyramine

The hydrochloride salt form of dopamine, a monoamine compound with positive inotropic activity. Dopamine is a naturally occurring catecholamine formed by decarboxylation of dehydroxyphenylalanine and a precursor of norepinephrine and epinephrine. Dopamine binds to alpha-1- and beta-1- adrenergic receptors. Mediated through myocardial beta-1-adrenergic receptors, dopamine increase heart rate and force, thereby increasing cardiac output. Alpha-1-adrenergic receptor stimulation on vascular smooth muscle, leads to vasoconstriction and results in an increase in systemic vascular resistance. Stimulation of dopaminergic receptors in renal vasculature, leads to renal blood vessel dilation, and an increase in glomerular filtration rate, renal blood flow, sodium excretion, and urine output.

Can I take Dopamine while breastfeeding?

No information is available on the use of dopamine during breastfeeding. Because of its poor oral bioavailability and short half-life, any dopamine in milk is unlikely to affect the infant. Intravenous dopamine infusion may decrease milk production. Dopamine is known to reduce serum prolactin in nonnursing women, but no information is available on its effect on milk production in nursing mothers.

Possible effects on lactation

Intravenous dopamine infusion in doses of 2 to 5 mcg/kg/minute given to nonnursing subjects and in women with hyperprolactinemia decreases serum prolactin concentrations.[1][2][3][4][5] However, relevant published information on the effect of intravenous dopamine on milk production in nursing mothers was not found as of the revision date. The prolactin level in a mother with established lactation may not affect her ability to breastfeed.
