Dopamine is a neurotransmitter normally produced by the body and it acts as a precursor to norepinephrine. Its effects ultimately depend on the dosage prescribed, as well as the patient’s condition. Dopamine given in low doses typically stimulates the receptors that produce vasodilation of the renal and mesenteric arteries.

Dopamine Injection: Uses, Dosage & Side Effects
dopamine causes renal vasodilation and natriuresis. angiotensin II exerts a constrictor effect on the efferent arterioles. prostaglandins increase blood flow in the renal cortex and decrease blood flow in the renal medulla. acetylcholine produces renal vasoconstriction . Erythropoietin: is produced in the juxtaglomerular cells of the kidney

One of our research interests is studying if the action of locally produced dopamine, a neurotransmitter, has an effect on the sodium-permeable ion channels and the relationship of dopamine to the sodium transporters. The inhibition of kidney dopamine receptor expression reduces daily urinary sodium excretion significantly, and disruption of ...

Dopamine β -hydroxylase catalyses the oxidation of dopamine in order to introduce an alcohol function leading to the formation of noradrenaline. N-Methyl transferase introduces a methyl group onto the nitrogen atom of noradrenaline. Page reference: 595-596. a. A = Tyrosine hydroxylase. b. B = Dopa decarboxylase. c.

Low dose (1-5ug/kg/min): acts on D receptors (Dopamine receptors are also located in brain) but these are structurally different from the ones in the kidney, D receptors in kidney are affected – produces renal dilation and hence improves renal flow ( prevents renal failure during shock (especially septic shock).
