“The administration of PABA in rats was followed by a substantial reduction in total urinary excretion of platinum (P < 0.05) and by a significant (P < 0.01) lower concentration of DDP derived platinum in the urine collected during the first 4 h after treatment.”
“The combined treatment with PABA produced a significant increase in the plasma concentrations of total platinum , without affecting the levels of platinum species in the plasma ultrafiltrate.”
“Total 24-h urinary excretion of platinum was also decreased, although not significantly, by PABA.”
