Effects of dopamine on kidney function and on the adenyl cyclase phosphodiesterase system in man. 1976

J Vlachoyannis, and G Weismüller, and W Schoeppe

Clearance studies were made to determine the influence of intravenous infusions of dopamine (between 2.5 and 3.5 mug.kg.-1min.-1) on renal function and on the adenyl cyclase phosphodiesterase system in eleven patients with chronic renal disease. Glomerular filtration rate (+ 19%), effective renal plasma flow )+ 29%), sodium (+ 199%) and potassium (+ 40%) clearances were significantly increased. These effects were associated with a stimulation of the adenyl cyclase phosphodiesterase system demonstrated by an increase of cyclic adenosine 3'5'-monophosphate in plasma and urine. The results suggest that dopamine probably affects renal function by activating the adenyl cyclase phosphodiesterase system.

D004298	Dopamine	One of the catecholamine NEUROTRANSMITTERS in the brain. It is derived from TYROSINE and is the precursor to NOREPINEPHRINE and EPINEPHRINE. Dopamine is a major transmitter in the extrapyramidal system of the brain, and important in regulating movement. A family of receptors (RECEPTORS, DOPAMINE) mediate its action.
