After intraperitoneal administration of 14C-labeled PVP iodine with lower and higher molecular weights (viscosity constants K 17 and K 28) in 124 female Wi star rats, both substances were resorbed completely from the peritoneal cavity. The distribution and the retention of PVP with higher molecular weights in all organs is identicaL to the already known phenomena which occur after intravenous administration of PVP. Compared with the half­ life of PVP K 17, that of PVP K 28 is clearly prolonged in all organs. Furthermore, the renal elimination of the high-molecular weight PVP K 28 is significantly slower.
