Dopamine, sold under the brand name Intropin among others, is a medication most commonly used in the treatment of very low blood pressure, a slow heart rate that is causing symptoms, and, if epinephrine is not available, cardiac arrest. [4] In newborn babies it continues to be the preferred treatment for very low blood pressure. [5]
It has been described as an MRA of serotonin and dopamine that lacks induction of aortic contraction in vitro and hence may lack concomitant norepinephrine release (i.e., it may be a serotonin–dopamine releasing agent (SDRA)). [1] [2] [3] However, EC 50 values for monoamine release by 4-MTDMA were not reported.
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.
Amphetamine, an NDRA and one of the most well-known DRAs. 4-Methylaminorex (4-MAR), the cis- isomer being one of the most dopamine-selective NDRAs known.. A dopamine releasing agent (DRA) is a type of drug which induces the release of dopamine in the body and/or brain.
It is thought that the therapeutic effects of docarpamine are mediated by activation of peripheral dopamine D 1 receptors. [ 3 ] Although docarpamine is orally active and can achieve therapeutic levels of dopamine in blood, [ 1 ] relatively high doses and frequent administration of the drug (e.g., 600–750 mg every 8 hours) are required when ...
Side effects of levodopa include nausea, the wearing-off phenomenon, dopamine dysregulation syndrome, and levodopa-induced dyskinesia, among others. [3] The drug is a centrally permeable monoamine precursor and prodrug of dopamine and hence acts as a dopamine receptor agonist. [3] Chemically, levodopa is an amino acid, a phenethylamine, and a ...
3,4-Dihydroxyphenylacetaldehyde (DOPAL), also known as dopamine aldehyde, is a metabolite of the monoamine neurotransmitter dopamine formed by monoamine oxidase (MAO). [ 2 ] [ 3 ] Other metabolic pathways of dopamine metabolism include methylation by catechol O -methyltransferase (COMT) into 3-methoxytyramine and β-hydroxylation by dopamine β ...
The epinine, an analogue of dopamine, can stimulate dopamine receptors and to a lesser degree adrenergic receptors. [9] Thus it is believed that epinine is the pharmacologically active moiety. It has been shown that the half-life of ibopamine is short to about 2 minutes in the aqueous humour owing to the fast hydrolysis. [ 10 ]
