Summary Riboflavin excretion by renal tubular cells would seem to use the transport system for organic bases. This conclusion is based on the fact that tolazoline selectively inhibits riboflavin while not impairing PAH excretion. PAH excretion was even enhanced by tolazoline presumably as a result of diversion of more blood to the portal circulation. Benemid can inhibit transport of both PAH and riboflavin.

Renal clearances of riboflavin and inulin-14C-carboxylic acid were determined in Wistar rats anaesthetized with ethanol + N2O or amobarbital sodium and it is suggested that rib oflavin, as well as being secreted into the tubules, is in addition reabsorped from the tubule by an easily saturable mechanism.
Absorption, Protein Binding, and Elimination of Riboflavin
The absorption, distribution, metabolism, and excretion of riboflavin have been studied most extensively in man and in the rat, and considerable species differences in the intestinal absorption, protein binding, biliary excretion, and renal excretion have been revealed.
Riboflavin transport by isolated perfused rabbit renal proximal tubules.
Rabbit renal proximal tubular transport of riboflavin was examined by using the in vitro isolated tubule perfusion technique and addition of chlorpromazine, a phenothiazine derivative, inhibited both J(lb) and J(bl), raising the concern about the nutritional status in patients receiving such a type of medication.
Organic cation transport in avian renal brush-border membrane vesicles.
The present study focuses on the characterization of Organic Cation Transport by Avian Renal Brush-Border Membrane Vesicles and the effects of transmembrane potential on organic cation transport in avian renal brush border membranes.
