It is unclear if dopamine is safe to use during pregnancy or breastfeeding. [4] At low doses dopamine mainly triggers dopamine receptors and β1-adrenergic receptors while at high doses it works via α-adrenergic receptors. [4] Dopamine was first synthesized in a laboratory in 1910 by George Barger and James Ewens in England. [8]
Domperidone has no officially established dosage for increasing milk supply, but most published studies have used 10 mg three times daily for 4 to 10 days (30 mg per day). [ 36 ] The US Food and Drug Administration (FDA) has expressed concerns about serious adverse side effects and concerns about its effectiveness. [ 34 ]
A dopamine reuptake inhibitor (DRI) is a class of drug which acts as a reuptake inhibitor of the monoamine neurotransmitter dopamine by blocking the action of the dopamine transporter (DAT). Reuptake inhibition is achieved when extracellular dopamine not absorbed by the postsynaptic neuron is blocked from re-entering the presynaptic neuron.
Ginkgo biloba extract (EGb761) — "The norepinephrine (NET), the serotonin (SERT), the dopamine (DAT) uptake transporters and MAO activity are inhibited by EGb761 in vitro" [157] St John's Wort — natural product and over-the-counter herbal antidepressant Hyperforin; Adhyperforin; Uliginosin B — IC 50 DA = 90 nM, 5-HT = 252 nM, NE = 280 nM ...
Medifoxamine (Cledial, Gerdaxyl) is an antidepressant that appears to act as an SDRI as well as a 5-HT 2 receptor antagonist. [3] Sibutramine (Reductil, Meridia, Siredia, Sibutrex) is a withdrawn anorectic that itself as a molecule in vitro is an SNDRI but preferentially an SDRI, with 18.3- and 5.8-fold preference for inhibiting the reuptake of serotonin and dopamine over norepinephrine ...
Tiapride is a dopamine D 2 and D 3 receptor antagonist. It is more selective than other neuroleptic drugs such as haloperidol and risperidone, which not only target four of the five known dopamine receptor subtypes (D 1-4), but also block serotonin (5-HT 2A, 2C), α 1 - and α 2-adrenergic, and histamine H1 receptors. [2]
TCAs do not block dopamine transport directly but might facilitate dopaminergic effects indirectly by inhibiting dopamine transport into noradrenergic terminals of the cerebral cortex. [29] Because they affect so many different receptors, TCAs have adverse effects, poor tolerability, and an increased risk of toxicity.
Dopexamine is a synthetic analogue of dopamine that is administered intravenously in hospitals to reduce exacerbations of heart failure and to treat heart failure following cardiac surgery. It is not used often, as more established drugs like epinephrine, dopamine, dobutamine, norepinephrine, and levosimendan work as well.
