OBSERVATIONS ON THE URINARY EXCRETION OF SULFADIAZINE

Abstract
The greatest and most prolonged increase in excretion of sulfadiazine resulted from the adm. of NaHCO3 in amts. sufficient to insure a highly alkaline urine. A decrease in the conc. of the drug in the urine was obtained most rapidly by the intraven. inj. of a large volume of 5-10% glucose soln. in distilled water. The ingestion of water in large amts. produced a similar result somewhat less rapidly. The intraven. infusion of physiological saline gave a less marked reduction in the conc. of drug in the urine and the effect was more delayed. Only the first of these 3 procedures was accompanied by a large increase in drug output.
