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]
Since it does not act on dopamine receptors to inhibit the release of norepinephrine (another α 1 agonist), dobutamine is less prone to induce hypertension than is dopamine. Dobutamine is predominantly a β 1 -adrenergic agonist , with weak β 2 activity, and α 1 selective activity, although it is used clinically in cases of cardiogenic shock ...
Dopamine therapy is the regulation of levels of the neurotransmitter dopamine through the use of either agonists, or antagonists; and has been used in the treatment of disorders characterized by a dopamine imbalance. Dopamine replacement therapy (DRT) is an effective treatment for patients with decreased levels of dopamine.
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.
Cabergoline, sold under the brand name Dostinex among others, is a dopaminergic medication used in the treatment of high prolactin levels, prolactinomas, Parkinson's disease, and for other indications. [3] It is taken by mouth. Cabergoline is an ergot derivative and a potent dopamine D 2 receptor agonist. [4]
Typically, the recommended starting dosage for Wellbutrin is 200mg per day, with a maximum dosage of 450mg per day. The starting dosage is taken as 100mg twice per day.
l-DOPA is the precursor to the neurotransmitters dopamine, norepinephrine (noradrenaline), and epinephrine (adrenaline), which are collectively known as catecholamines. Furthermore, l-DOPA itself mediates neurotrophic factor release by the brain and CNS.
Amisulpride is approved and used at low doses in the treatment of dysthymia and major depressive disorder. [10] [20] [11] [21] [22] [23] Whereas typical doses used in schizophrenia block postsynaptic dopamine D 2-like receptors and reduce dopaminergic neurotransmission, low doses of amisulpride preferentially block presynaptic dopamine D 2 and D 3 autoreceptors and thereby disinhibit dopamine ...
