Tclk. Wa et al., EFFECTS OF FRUSEMIDE ON THE URINARY-EXCRETION OF DOPAMINE AND 5-HYDROXYTRYPTAMINE IN NORMAL MAN, British journal of clinical pharmacology, 42(4), 1996, pp. 522-524
The effects of frusemide on the urinary excretion of dopamine and 5-hy
droxytryptamine (5-HT) were investigated in eight healthy male subject
s in a randomized, placebo-controlled, cross-over study. Frusemide pro
duced the expected rise in urinary dopamine excretion but it did not a
ffect 5-HT excretion when compared with placebo. The lack of an effect
on 5-HT excretion in man contrasts with studies in the rat which have
reported a marked increase in 5-HT excretion after administration of
this loop diuretic.
