dopamine

 [do´pah-mēn]
a compound produced by the decarboxylation of dopa; it is the direct precursor in the synthesis of norepinephrine and is also a neurotransmitter in the central nervous system. It is administered intravenously to correct hemodynamic imbalance in persons with shock because it increases blood pressure, especially systolic pressure, as well as urinary output; it is also used as a cardiac stimulant.

do·pa·mine (DM),

(dō'pă-mēn),
An intermediate in tyrosine metabolism and precursor of norepinephrine and epinephrine; neurotransmitter is the peripheral and central nervous systems; depletion of dopamine produces Parkinson disease.

dopamine

(dō′pə-mēn′)
n.
A monoamine neurotransmitter formed in the brain by the decarboxylation of dopa and essential to the normal functioning of the central nervous system. A reduction in its concentration within the brain is associated with Parkinson's disease.

dopamine

Neurology A catecholamine hormone and neurotransmitter essential to CNS activity; it is involved motor control, cognition, and reward; abnormal dopamine levels occur in Parkinson's disease, paranoia, memory and concentration defects; dopamine may modulate endorphin levels, altering perception of pain and pleasure; it restricts prolactin, affecting libido See Biogenic amine, Catecholamine, Indolamine, Serotonin.

do·pa·mine

(DM) (dō'pă-mēn)
An intermediate in tyrosine metabolism and precursor of norepinephrine and epinephrine.

dopamine

A monoamine NEUROTRANSMITTER and hormone with an adrenaline-like action. Dopamine is the principal neurotransmitter in the extrapyramidal system. It is formed in the brain from the amino acid tyrosine via dopa and the latter, in the form of levodopa is used to treat PARKINSON'S DISEASE. Dopamine is the precursor of noradrenaline. It is also concerned with mood, memory and food intake. Excess is associated with psychiatric disorders. Dopamine is converted into at least 30 other substances some of which are hallucinogenic. The drug is on the WHO official list.

do·pa·mine

(dō'pă-mēn)
An intermediate in tyrosine metabolism and precursor of norepinephrine and epinephrine.
