Abstract
Pure bovine pancreatic polypeptide (PP) was infused into 23 healthy subjects at doses of 1, 3, and 5 pmol/kg/min over 60 minutes and plasma PP was measured by radioimmunoassay. During the infusions mean plasma levels of 203 +/- 34, 575 +/- 73, and 930 +/- 48 pmol/l respectively were achieved. Mean disappearance half time on stopping the infusion was 6.9 +/- 0.3 min (mean +/- SEM). The metabolic clearance rate was 5.1 +/- 0.2 ml/kg/min (mean +/- SEM) and the apparent volume of distribution was calculated to be 51 +/- 3 ml/kg (mean +/- SEM). This study provides for the first time pharmacokinetic data for PP in man.
