Studies on the inhibition of clearance of organic dyes by Saramycetin.

1. Saramycetin, a polypeptide antifungal antibiotic has been found to retard the clearance of sulphobromophthalein (BSP) in man. An explanation for this observation was sought in several lower species.2. Doses of Saramycetin without effect on the other standard tests of hepatic function or on hepatic morphology profoundly altered the disposition of BSP and several other dyes in mice and dogs.3. Saramycetin strongly inhibited the hepatic enzyme which conjugates BSP to reduced glutathione, provoked a regurgitation of BSP from the liver into the bloodstream, and was anticholeretic in the dog.4. These diverse actions of Saramycetin may, in concert, explain the altered clearance of BSP. It is suggested that low doses of Saramycetin exert a pharmacological effect on certain hepatic excretory processes, whereas high doses are toxic.
